REM Sleep Behavior Disorder and Cognitive Functions in Parkinson's Patients: A Systematic Review.

Sleep disorders, such as REM sleep behavior disorder (RBD) and excessive daytime sleepiness, are among the most common non-motor symptoms in subjects with Parkinson's disease (PD). Sleep disorders have a major negative impact on the quality of life of patients and their caregivers. In addition, REM sleep behavior disorder is an important risk factor for cognitive impairment in PD. This systematic review was conducted on studies investigating the influence of RBD on cognitive performance in PD subjects. We searched the PubMed and Scopus databases, screened the references of the studies included, and reviewed articles for additional citations. From the first 244 publications, we included only 11 studies that met the search criteria. The results showed that sleep disorders in PD were associated with impaired executive functions, visual-constructive abilities, reduced attention, and episodic verbal memory, and could predict the possible risk of developing dementia.

Psychological symptoms in Multiple Sclerosis and the role of marital status: results from a retrospective single-center study.

BACKGROUND: Married people have, on average, better mental health than no married people. Psychological symptoms as anxiety and depression occur frequently in patients with multiple sclerosis (MS), increasing the severity of neurologic disability. The aim of this retrospective study was to investigate the relationship between functional disability and psychological symptoms differentiating by marital status. METHODS: In this study 150 MS outpatients without a history of psychological disorders were selected from the hospital database. The outpatient procedure for all patients includes the administration of the Expanded Disability Status Scale and the questionnaire Symptoms Checklist-90-Revised (SCL-90-R) a multidimensional self-report inventory, consisting of 90 items covering nine clinical dimensions: somatization (SOM), obsessive-compulsive (OC), interpersonal sensitivity (IS), depression (DEP), anxiety (ANX), hostility (HOS), phobic anxiety (PHOB), paranoid ideation (PAR), psychoticism (PSY), and three global indices of distress: global severity index (GSI), positive symptoms total (PST) and positive symptom distress index (PSDI). According to marital status, subjects were subdivided in single, married (including cohabitants), and divorced (including separated). A nonparametric group comparisons analysis was performed, as well as multivariate analysis which included generalized linear regression models. RESULTS: Regression results showed that functional disability was a significant predictor for all SCL- 90-R subscales. Moreover, it would seem that the single condition might be a protective factor for the development of psychological symptoms in SM patients. Notably, findings showed that younger subjects were predominantly single and had less psychological symptoms, whereas patients with greater psychological alterations were older in a stable affective couple relationship, presenting an elevation in depression, anxiety, somatization and compulsive, and obsessive scales. CONCLUSION: Numerous factors contribute to the onset of psychological disorders in multiple sclerosis. Marriage does not represent a protective factor for the development of psychological symptoms in SM patients. Future investigation is needed to ascertain the prevalence and underlying causes of psychological symptoms.

Paving the Way for Predicting the Progression of Cognitive Decline: The Potential Role of Machine Learning Algorithms in the Clinical Management of Neurodegenerative Disorders.

Alzheimer's disease (AD) is the most common form of neurodegenerative disorder. The prodromal phase of AD is mild cognitive impairment (MCI). The capacity to predict the transitional phase from MCI to AD represents a challenge for the scientific community. The adoption of artificial intelligence (AI) is useful for diagnostic, predictive analysis starting from the clinical epidemiology of neurodegenerative disorders. We propose a Machine Learning Model (MLM) where the algorithms were trained on a set of neuropsychological, neurophysiological, and clinical data to predict the diagnosis of cognitive decline in both MCI and AD patients. METHODS: We built a dataset with clinical and neuropsychological data of 4848 patients, of which 2156 had a diagnosis of AD, and 2684 of MCI, for the Machine Learning Model, and 60 patients were enrolled for the test dataset. We trained an ML algorithm using RoboMate software based on the training dataset, and then calculated its accuracy using the test dataset. RESULTS: The Receiver Operating Characteristic (ROC) analysis revealed that diagnostic accuracy was 86%, with an appropriate cutoff value of 1.5; sensitivity was 72%; and specificity reached a value of 91% for clinical data prediction with MMSE. CONCLUSION: This method may support clinicians to provide a second opinion concerning high prognostic power in the progression of cognitive impairment. The MLM used in this study is based on big data that were confirmed in enrolled patients and given a credibility about the presence of determinant risk factors also supported by a cognitive test score.

Traumatic Brain Injury and Related Antisocial Behavioral Outcomes: A Systematic Review.

Background and Objectives: Higher level of aggression and antisocial behavior have been found in the period following head trauma. These changes are attributable to specific brain alterations that generally involved frontal lobe, insula and limbic system. A descriptive review was conducted on the specificity of aggressive behavior in relation to traumatic brain injury by evaluating numerous variables, focusing on age at the time of trauma and neuroimaging studies. Materials and Methods: We searched on PubMed and the Web of Science databases to screen references of included studies and review articles for additional citations. From an initial 738 publications, only 27 met the search criteria of describing the relationship between aggression, brain alterations and traumatic brain injury. Results: These findings showed that traumatic brain injury (TBI) is related to changes in behavior, personality and mood. Conclusions: The development of aggressive and criminal behavior is associated with multiple factors, including the etiology of injury, environmental, psychosocial and personality factors and age at the time of trauma.

The Impact of Non-Motor Symptoms on Quality of Life in Cervical Dystonia.

Cervical dystonia (CD) is characterized by cranial muscle overactivity leading to abnormal intermittent or continuous posturing of the head. Nowadays, the treatment of patients suffering from this condition focuses principally on the motor component of the disorder, certainly the invaliding part; however, it leaves out the non-motor one that has a similarly invalidated effect on the quality of the subject's life. This review was conducted on studies investigating the impact of non-motor symptoms on levels of quality of life. We searched on the PubMed, EMBASE and Web of Science databases and screening references of included studies and review articles for additional citations. From an initial 150 publications, we included only five studies that met the search criteria. The results showed that anxiety, depression, pain and sleep quality have a great influence on patients' health and on the outcome of the disease. Future studies should focus more on investigating the non-motor components of CD as an integral part of the clinical management of dystonic patients in order to improve their well-being.

Toward social-health integration in Sicily: description of the first hub and spoke model to improve the diagnostic therapeutic care paths for neurorehabilitation.

Introduction: The study describes a hub and spoke network for neuro-rehabilitation recently activated in Sicily, and evaluates the before-after changes yielded, in terms of integrated care. Methods: A set of indicators based on data contained in the administrative database of inpatients of the Regional Health System are presented and discussed. Statistical analysis was conducted both globally and separately for the 9 Sicilian provinces (Agrigento, Caltanissetta, Catania, Enna, Messina, Palermo, Siracusa, Ragusa, and Trapani). Results: Results showed an increase in admissions of people residing in the province where the Spokes have been opened: Trapani (+32.4%), Messina (+7.8%) and Palermo (+4.4%); besides a significant increase of patients from healthcare facilities proportion (p = 0.001) and from acute wards (p = 0.029). In addition, we found a decrease of discharge to protected healthcare facilities (p = 0.001) and to acute wards (p < 0.001), as well as an increase of discharges to home (p = 0.018). Discussion: In conclusion, it would seem that the activation of this network has facilitated the management of these patients, avoiding unnecessary migrations to other provinces and/or regions, and improving the regional care service for neuro-rehabilitation. Future research will be direct to investigate this aspect, focusing on before-after variations in hospitalization rates and origin- destination patient flows.

Body Image and Emotional Status in Patients with Acquired Brain Injury.

Emotional experiences can lead to a real or distorted self-representation. After brain damage, altered self-perception of one's own body image is frequent. This study evaluates the relationship of mood disorders and lesion sites on body image in a cohort of ABI patients. A total of 46 patients (26 men, 20 women) without severe physical impairments were found eligible for this study. Patients underwent Beck's Depression Inventory and the Hamilton Rating Scale for Anxiety to assess mood disorders, whereas the Body Image Scale and Human Figure Drawing were used to evaluate body dissatisfaction and implicit body image. The Montreal Cognitive Assessment was used to assess patients' cognitive condition. We found a moderate correlation between depression and body image (r = 0.48), as well as between anxiety and body image (r = 0.52), and the regression model also reported the right lesion site as a predictive variable for body image score. In addition, the regression model built by Human Figure Drawing scores showed anxiety, cognitive functioning, and a marital status of single to be significant predictors. The study confirmed that participants with acquired brain injury have deficits in body representation associated with mood disorders, regardless of the side of the lesions. A neuropsychological intervention could be useful for these patients to improve their cognitive performance and learn to manage emotional dysfunction in order to increase their self-perception of body image and improve their quality of life.

The Relationship between Body Image, Disability and Mental Health in Patients with Multiple Sclerosis.

BACKGROUND: Multiple sclerosis is a progressive degenerative disorder that frequently involves the development of physical and emotional changes, including loss of limb function or sensitivity, sexual dysfunction, and cognitive and mood alterations. It is likely that these alterations lead to changes in body aspects. However, knowledge about body image perception in multiple sclerosis is lacking. PURPOSE: The present study investigated the relationship between body image perception and its correlation with a disability, neuropsychiatric symptoms, and self-esteem. METHODS: A total of 100 outpatients with relapsing-remitting multiple sclerosis underwent neurological assessment using the Expanded Disability Status Scale. Participants also completed the Body Image Scale (BIS), Rosenberg Self-Esteem Scale (RSES), and Symptom Checklist-90-Revised (SCL-90-R). RESULTS: We found a significant positive correlation between body image and disability (r = 0.21; p = 0.03), body image and self-esteem (r = -0.52; p < 0.001), body image and somatization (r = 0.44; p < 0.001), body image and depression (r = 0.57; p < 0.001), and body image and anxiety (r = 0.5; p < 0.001). CONCLUSIONS: The body is considered one of the main parts of a person's identity. Dissatisfaction with one's own body changes the general evaluation of the "self". The body image construct has important health outcomes and should be studied more in patients with multiple sclerosis.

Migraine Treatment Using Erenumab: Can Lead to a Cognitive and Psychological Qualitative Improvement?

Migraine is one of the most disabling disorders in the world, associated with poor quality of life. Migraine prevention strategies have increasingly evolved since monoclonal antibodies against the calcitonin gene-related peptide (CGRP), or its receptor, were identified. CGRP is the ideal target of monoclonal antibodies (mAbs). In particular, erenumab is the mAb that has shown good therapeutic efficacy in reducing pain intensity and having high tolerability. In this study, we aimed to investigate the efficacy of erenumab on both cognitive performance and psychological well-being. This was a pilot study with a retrospective design that included 14 subjects (2 males and 12 females), with a mean age of 52.29 ± 9.62, who attended the Headache and Migraine outpatient clinic of the IRCCS Centro Neurolesi Bonino-Pulejo of Messina. The evaluation consisted of measuring cognitive and psychological functioning. Comparing clinical and psychometric test scores between baseline and follow-up, we found a significant improvement in both cognitive performance and quality of life. We also observed a decrease in migraine disability. Our findings have shown improvements in global cognitive performance and quality of life in migraine patients taking erenumab.

Role of Nutrition in the Etiopathogenesis and Prevention of Nonalcoholic Fatty Liver Disease (NAFLD) in a Group of Obese Adults.

Nonalcoholic fatty liver disease (NAFLD) is liver damage characterized by an accumulation of triglycerides in hepatocytes of >5% (due to an alteration of the balance of the lipid metabolism in favour of lipogenesis compared to lipolysis) that is not induced by the consumption of alcohol. The pathology includes simple steatosis and nonalcoholic steatohepatitis, or NASH (steatosis associated with microinflammatory activities), which can evolve in 15% of subjects with hepatic fibrosis to cirrhosis and the development of hepatocellular carcinoma. The aim of this study is to report the role of macro- and micronutrients in the pathogenesis and prevention of NAFLD in obese subjects. A total of 22 obese or overweight patients with hepatic steatosis were monitored periodically, evaluating their eating habits, fasting glycaemia, lipid picture, liver enzymes, anthropometric parameters, nutrition status, liver ultrasound, oxidative stress, and adherence to the Mediterranean diet. A statistical analysis shows a significant positive relationship between total cholesterol and the Mediterranean adequacy index (MAI) (r = -0.57; p = 0.005) and a significant negative relationship between ALT transaminases and the MAI (r = -0.56; p = 0.007). Nutrition and diet are important factors in the pathogenesis and prevention of NAFLD. The dietary model, based on the canons of the Mediterranean diet, prevents and reduces the accumulation of fat in hepatocytes. Therefore, in agreement with other studies in the literature, we can state that a dietary model characterized by foods rich in fibre, carotenoids, polyphenols, ω3 fatty acids, folic acid, and numerous other molecules is inversely correlated with the serum levels of ALT transaminases, an enzyme whose level increases when the liver is damaged and before the most obvious symptoms of organ damage appear.

Auditing the Audits: A Systematic Review on Different Procedures in Telemedicine.

Telemedicine is a process of delivering health care using information and communication technologies. Audit and feedback (A&F) constitute a systematic intervention that is aimed at collecting data, which are subsequently compared with reference standards and then returned to health care operators through feedback meetings. The aim of this review is to analyse different audit procedures on and by mean of telemedicine services and to identify a practice that is more effective than the others. Systematic searches were performed in three databases evaluating studies focusing on clinical audits performed on and by means of telemedicine systems. Twenty-five studies were included in the review. Most of them focused on telecounselling services with an audit and a maximum duration of one year. Recipients of the audit were telemedicine systems and service users (general practitioners, referring doctors, and patients). Data resulting from the audit were inherent to the telemedicine service. The overall data collected concerned the number of teleconsultations, service activity, reasons for referral, response times, follow-up, reasons why treatment was not completed, technical issues, and other information specific to each telemedicine service. Only two of the considered studies dealt with organizational aspects, and of these, only one analysed communicative aspects. The complexity and heterogeneity of the treatments and services provided meant that no index of uniformity could be identified. Certainly, some audits were performed in an overlapping manner in the different studies, and these show that although attention is often paid to workers' opinions, needs, and issues, little interest was shown in communicative/organizational and team dynamics. Given the importance and influence that communication has in teamwork and care settings, an audit protocol that takes into account intra- and extra-team communication processes could be essential to improving the well-being of operators and the quality of the service provided.

Audit as a Tool for Improving the Quality of Stroke Care: A Review.

INTRODUCTION: A clinical audit is a tool that allows the evaluation of and improvement in the quality of stroke care processes. Fast, high-quality care and preventive interventions can reduce the negative impact of stroke. OBJECTIVE: This review was conducted on studies investigating the effectiveness of clinical audits to improve the quality of stroke rehabilitation and stroke prevention. METHOD: We reviewed clinical trials involving stroke patients. Our search was performed on PubMed databases, Web of Science, and Cochrane library databases. Of the 2543 initial studies, 10 studies met the inclusion criteria. RESULTS: Studies showed that an audit brought an improvement in rehabilitation processes when it included a team of experts, an active training phase with facilitators, and short-term feedback. In contrast, studies looking at an audit in stroke prevention showed contradictory results. CONCLUSIONS: A clinical audit highlights any deviations from clinical best practices in order to identify the causes of inefficient procedures so that changes can be implemented to improve the care system. In the rehabilitation phase, the audit is effective for improving the quality of care processes.

Music Therapy in Global Aphasia: A Case Report.

Patients affected by global aphasia are no longer able to understand, produce, name objects, write and read. It occurs as a result of functional damage of ischemic or hemorrhagic origin affecting the entire peri-silvan region and frontal operculum. Rehabilitation training aims to promote an early intervention in the acute phase. We described a case of a 57-year-old female patient with left intraparenchymal fronto-temporo-parietal cerebral hemorrhage and right hemiplegia. After admission to clinical rehabilitative center, the patient was not able to perform simple orders and she presented a severe impairment of auditory and written comprehension. Eloquence was characterized by stereotypical emission of monosyllabic sounds and showed compromised praxis-constructive abilities. Rehabilitation included a program of Neurologic Music Therapy (NMT), specifically Symbolic Communication Training Through Music (SYCOM) and Musical Speech Stimulation (MUSTIM). Rehabilitative treatment was measured by improved cognitive and language performance of the patient from T0 to T1. Music rehabilitative interventions and continuous speech therapy improve visual attention and communicative intentionality. In order to confirm the effectiveness of data presented, further extensive studies of the sample would be necessary, to assess the real role of music therapy in post-stroke global aphasia.

Importance of telemedicine in mild cognitive impairment and Alzheimer disease patients population during admission to emergency departments with COVID-19.

In March 2020, the World Health Organization declared a global pandemic due to the new coronavirus SARS-CoV-2, and several governments have planned a national quarantine to control the spread of the virus. Acute psychological effects during hospitalization in frail elderly individuals with special needs, such as patients with dementia, have been little studied. The greatest distress manifested by these kinds of patients was isolation from their families during hospitalization. Thus, structured video call interventions were carried out to family caregivers of patients diagnosed with dementia during their hospitalization in the COVID-19 ward. The purpose of this quasi-experimental study was to assess changes in cognitive and behavioral symptoms in both patients and caregivers. All study participants underwent psychological assessments. Specifically, the psychological well-being states of patients and their caregivers were measured at admission (T0) and discharge (T1) using psychometric tests and clinical scales. Each participant received an electronic device to access video calls in addition meetings were scheduled with the psychologist and medical team to keep caregivers updated on the health status of their relatives. A psychological support and cognitive rehabilitation service was also provided. Significant differences were found in all clinical variables of the caregiver group. Results showed a significant relationship in the quality of life score between the patient and caregiver groups. The results of this study has highlighted the importance of maintaining significantly effective relationships during the hospitalization period of patients admitted to COVID wards.

Hypnotherapy as a Nonpharmacological Treatment for the Psychological Symptoms of Multiple Sclerosis.

Context: Stress and chronic pain are the factors that most influence the quality of life and well-being of people with MS, and 90% of adults with MS suffer from persistent fatigue. These symptoms can be associated with other disorders such as depression, and drug treatments provide inadequate comfort for most people with them. Objective: The study intended to examine the impact of hypnosis and hypnotherapy in the management of symptoms of people with multiple sclerosis (MS), such as stress, chronic pain, an inferior quality of life, and a lack of psychological well-being. Design: The research team performed a systematic narrative review by searching the PubMed and Web of Science databases, including review articles and other studies for additional citations. Setting: The study was conducted at our Scientific Institute for Research (IRCCS) in Messina. Results: Only 14 of 121 publications met the inclusion criteria and were selected. Hypnotic treatment is an effective therapy that has beneficial impacts on the intensity of perceived pain, psychological well-being, mood disorders, and fatigue, and in addition, it significantly improves physical functioning in MS patients. The same effects haven't been obtained with other nonpharmacological techniques. Conclusion: Hypnosis is an appropriate psychological therapy for the management of MS patients' symptoms.

Anxiety and Perception of Disease Control in Multiple Sclerosis Subjects Treated with Natalizumab.

Multiple sclerosis subjects treated with natalizumab face anxiety about developing progressive multifocal leukoencephalopathy (PML), besides the psychological distress caused by the disease. The aim of this study is to investigate whether increasing the frequency of neurological and nuclear magnetic resonance screening may affect anxiety and the perception of disease control in patients treated with natalizumab. A total of 62 relapsing-remitting multiple sclerosis patients were recruited from 2019 to 2020. All patients received conventional infusion treatments with natalizumab, along with a screening protocol for PML. Three clinical assessments were considered: at the beginning of the study (T0), after 3 months (T1) and after 6 months (T2). Patients were classified into three levels of risk, where level 1 represented a low risk of PML and level 3 a high risk. This classification determined treatment and screening protocol, i.e., the frequency of performing the Stratify test and the brain 3T NMR exam, as well as the frequency of infusion treatments. Anxiety and perception of disease control were assessed at T0, T1, and T2 by a skilled psychologist. The Friedman test and the Wilcoxon signed-rank test were used to compare outcomes at baseline with the two follow-ups. Statistical test results showed that the risk of PML (per 1000 patients) was significantly lower in women than in men (W = 198.5; p = 0.01). Moreover, significant differences between baseline and the two follow-ups were found, both for anxiety (F(2) = 122.6, p < 0.001) and for perception of disease control (F(2) = 123.5, p < 0.001). In both cases, there was significant improvement between baseline (T0) and the end of the study (T2) in any risk level (p < 0.001). An increase in the number of follow-ups, as well as an increase in instrumental investigations, might have a positive effect on both anxiety and the perception of disease control. However, there are many variables involved in the disease process that have an impact on patients' psychological well-being. Therefore, further and more extensive studies are necessary to evaluate how, and how much, each variable impacts the disease course.

Multisensory stimulation and rehabilitation for disability improvement: Lessons from a case report.

RATIONALE: Spastic quadriplegia is most severe form of Infantile Cerebral Palsy. Patients are unable to use their legs, arms and body and show language disorder and profound intellectual disability. The treatment of patients diagnosed with spastic quadriplegia is complex and multidisciplinary. In this case report we described the positive effect of multisensory environment (MSEs) rehabilitation, and the strategies and technologies used to provide child who have to severe spastic quadriplegia and intellectual disability, palsy with playful and fun activities designed according to his abilities. PATIENT CONCERN: A 7-years-old boy diagnosed with spastic quadriplegia and severe intellectual disability began rehabilitation by MSEs. DIAGNOSES: Spastic quadriplegia is most severe form of Infantile Cerebral Palsy. Patients are unable to use their legs, arms and body and show language disorder and profound intellectual disability. INTERVENTIONS: Multisensory room is a large environment containing various elements where child can interact spontaneously and independently. OUTCOMES: The comparison scores between T0-T1 showed a reduction in self-harm and motor stereotypies (hand flapping). Sustained attention was improved and we observed a better therapeutic compliance by means of greater involvement in gaming activities. CONCLUSION: The stimuli within the MSEs provided the child opportunities to express himself with facilities more suited to his potential. Future research should project designed randomized controlled trials to examine the efficacy of multisensory on reduction disability.

Effects of COVID-19 in Endocrine Patients: A Cross-Sectional Study.

Introduction: Home confinement due to COVID-19 lockdown led to changes in daily routines, including social interactions, as well as restrictions on the possibility of playing sports and eating habits. These changes could have a greater impact on patients suffering from chronic diseases, such as endocrine patients, especially in emotional and behavioral dimensions. Materials and Methods: This study aimed to assess the effects of COVID-19-induced quarantine on daily habits in a group of patients with endocrine disorders, focusing on food consumption, eating habits and sleep during the confinement. Eighty-five endocrine patients were enrolled. A structured interview was administered to investigate socio-demographic information, general medical conditions, and habits adopted during quarantine. All patients underwent the Spielberger State Anxiety Inventory (STAI-Y1) to assess state anxiety. Result: Results showed that subjects mainly had a sedentary lifestyle. We found a significant increase in the number of cigarettes in smokers and in meals consumed during confinement, as well as a high rate of sleep disturbance, especially insomnia. Notably, physical well-being resulted to be a predictive factor (OR = 0.38; 95%CI = [0.95,0.66]), whereas anxiety was a risk factor for sleep disorder (OR = 1.22; 95%CI = [1.10,1.40]), as was working in public and private offices and being a student. Conclusions: Changes in daily habits were likely due to the alterations in routine, resulting in greater boredom and inactivity during the day. In addition, future research should focus on the importance of patient adherence to therapy.

Feasibility, Usability, and Customer Satisfaction of the Tele-COVID19 Project, Sicilian Model.

Background and Objectives: In March 2020, COVID-19 pandemic affected the world. All countries, to limit viral transmission, imposed quarantine. This emergency exerted personal, social, economic, and psychological impact on people. For health systems, was needed to create alternative care pathways. Telemedicine can be helpful to reduce isolation, provide health care services, and monitor virus infections. Italian regions, including Sicily, have activated telemedicine services for management of patients with COVID-19. Objective: The purpose of study is to describe a Sicilian telemedicine model for management of COVID-19 patients, showing results on feasibility, usability and quality of service and patient satisfaction. Materials and Methods: This is a descriptive exploratory study on a telemedicine service for residents in Messina infected by COVID-19. It included monitoring of vital signs and specialist consultations (i.e., doctor, psychologists, social workers, and nutritionist biologists). Results: More than twenty percent (23.8%) of participants used tele-monitoring and tele-counselling services; 14.3% were only telemonitored. Participants judged positively telemedicine service (30% were quiet and 50% were very satisfied), as well as tool (70% were quiet and 10% were very satisfied). Telemonitoring had a low agreement (10% were slightly satisfied and 50% were neutral); tele-counselling had a high rate of satisfaction (40% quiet and 60% were very satisfied). Conclusions: This study showed that telemedicine model for Sicilian population affected by COVID-19 was feasible, easy to use and appreciated by patients. Our promising results allow us to assume that if in Sicily there was a return of the emergency, we would be ready to manage it This system can be the solution to remote management of these patients, to reduce isolation, provide health services, and monitor virus infections. The use of this technology should encourage future research to change the health care system and provides opportunities to ensure health and care for oneself and others.

Diffusion tensor imaging studies on subjects with suicidal thoughts and behaviors: A descriptive literature review.

OBJECTIVE: Globally, suicide represents the second leading cause of death in young people aged 15-29 years for both sexes, after traffic accidents. Suicide occurs not only in high-income countries, in high-income countries but it is a global phenomenon in all regions of the world and it represents a serious public health problem. METHOD: This review was conducted on studies focused on white matter alterations in people who have attempted or thought about suicide. We searched PubMed and Scopus databases and screened references of included studies and reviewed articles for additional citations. From the initial 21 publications, we included only 12 studies that met search criteria and described the association between white matter alterations and suicide. RESULTS: White matter alterations in suicidal behaviors were found in the prefrontal cortex, orbitofrontal cortex, internal capsule, corpus callosum, and default mode networks, which are critical cerebral areas involved in emotion processing and regulation, decision-making, executive functions, and empathy. CONCLUSIONS: White matter alteration in cerebral areas involving high cognitive process and emotional regulation to confer a heightened vulnerability for suicidal behavior. Suicide is a complex process ranging from suicidal ideation to planning, attempting, or committing suicide. The identification of abnormalities in underlying neural circuitry may help delineate the neurobiological basis for suicide risk.
