ABSTRACT

An influence of the Covid-19 pandemic on First Episode Psychosis (FEP) has been hypothesized. We previously reported an increase of FEP during the early stages of the pandemic in Milan, Italy. Here we report a 1-year follow-up of the same cohort and comparison with a FEP cohort from 2019. The higher proportion of non-chronic psychoses observed during the pandemic (58.62% in 2020 vs 43,75% in 2019) should be confirmed in larger cohorts over a longer follow-up period.

ABSTRACT

Anorexia Nervosa is one of the most common form of eating disorders. Cardiac involvement occurs in approximately 80% of patients. Few reports focused on the association between body weight fluctuations and echocardiographic abnormalities, considering linear measurements. We describe echocardiographic and clinical features among male and female patients with anorexia nervosa and the effect of weight gain on these parameters. We performed a single center, retrospective study of patients followed at a dedicated multidisciplinary Unit. The study population consisted of 81 patients, mean age 25 ± 11 years, 94% female. Median body mass index was 14.4 kg/m2 (25th-75th percentile 12.7-15.6 kg/m2). Patients with body mass index below the median value had more often pericardial effusion, smaller left ventricular mass and left ventricular end-diastolic volume and thinner interventricular septum. However, when indexed to body surface area, left ventricular mass and volumes were within the normal range in 90% of population. Patients with pericardial effusion showed mitral valve abnormalities and lower values of white blood cells and platelets, although within normal limits. Presence of pericardial effusion was not related to inflammatory parameters or low plasma protein levels. In 39 patients who displayed weight gain during a median follow-up of 189 days (25th-75th percentile 47-471), increased left ventricular mass, interventricular septum thickness, white blood cells and platelet count and decreased pericardial effusion were observed. Patients with anorexia nervosa have a specific echocardiographic pattern which seems to be proportional to the body size, suggesting a pathophysiological adaptation to the lack of substrates.

ABSTRACT

OBJECTIVE: The contribution of psychological and psychiatric symptoms in the development of Functional Neurological Disorders (FND) is unclear. We therefore aimed to investigate the role of different attachment styles (AS) and their relationship with psychiatric symptoms in FND patients as compared with both subjects with neurological disorders (ND) and healthy controls (HC); and the possible differences between patients with functional movement disorders (FMD) and with functional seizures. METHODS: In this case-control study, forty-six patients with FND were compared to 34 with ND and 30 HC, by means of an extensive battery to investigate the presence of alexithymia, depression, anxiety, dissociation and to explore their AS using the Revised Experiences in Close Relationships instrument (ECR-R). RESULTS: Patients with FND had higher depression and alexithymia as well as an avoidant pattern on the ECR-R than patients with ND. In the FND group, ECR-R avoidance was an independent predictor of psychiatric symptoms and, altogether, ECR-R avoidance, the somatic-affective component of depression and difficulty identifying feelings were independent predictors of FND. Gender, anxiety and difficulty identifying feelings predicted the presence of functional seizures. CONCLUSION: The avoidant AS may be an important psychological factor influencing the presence of mood disorders and alexithymia. Their co-occurence might drive maladaptive responses underlying the presence of FND. Although we demonstrated a large overlap between FND phenotypes, patients with functional seizures might have higher alexithymia, which in turn could explain a defensive response less anchored to body reactions and physical symptoms.

ABSTRACT

The ongoing Corona Virus Disease 2019 (COVID-19) pandemic appears to increase risk for mental illness, either directly due to inflammation caused by the virus or indirectly due to related psychosocial stress, resulting in the development of both anxious-depressive and psychotic symptoms. The purpose of the present study was to assess the frequency and characteristics of all patients with First Episodes Psychosis (FEP) without COVID-19 infection hospitalized in the first four months since lockdown in Milan. We recruited sixty-two patients hospitalized between March 8 to July 8, 2020 versus those first  hospitalized in the same period in 2019. The two subgroups were compared for sociodemographic variables and clinical characteristics of the episodes. Patients with FEP in 2020 were significantly older than patients with FEP in 2021, and presented with significantly less substances abuse. Interestingly, patients presenting with FEP in 2020 were significantly older than patients with FEP in 2019. These data are compatible with the greater vulnerability to stressful factors during the pandemic, as well as with the greater concern regarding a possible COVID-19 infection producing brain damage causing the FEP.

ABSTRACT

Psychiatric disorders in migraine patients have a higher prevalence than general population. The presence of psychiatric comorbidities may influence the complexity of the migraine pictures and be related to medication overuse. Severely impaired chronic migraineurs presenting with medication overuse are a challenge for headache clinics. Psychiatric comorbities, such as dependency-like behaviors, anxiety and mood symptoms, might account for headache-related disability and recurrent relapses into medication overuse after a successful detoxification. Within a sample of 63 chronic migraineurs with medication overuse and severe disability, we investigated to which extent clinical severity, affective states and attitudes about medication impact the overall functioning at time of detoxification. To unravel whether some of these factors could predict their long-term outcome, we followed and retest them 1 year after withdrawal. We hypothesized that the detoxification would have led to a partial improvement and not modified the attitudes toward medication and dependence. Detoxification improves most of the clinical and affective measures, but does not free from significant levels of pain intensity and headache-related disability. The partial benefit from detoxification, the severity bias and the maladaptive cognitive profile led us to believe that subgroups of chronic-relapsing migraineurs deserve a multidisciplinary approach that addresses not only the reduction of clinical severity but also specific cognitive and behavioral impairments.

ABSTRACT

Patients with chronic migraine developing medication-overuse headache (MOH) show dependency-like behaviors such as loss of control over analgesics despite adverse consequences on headaches, high rates of relapse after withdrawal from symptomatic medications, and compromised social functioning. Neuroimaging research suggests a common pathophysiology between substance-use disorders and MOH, which involves functional alterations in fronto-striatal networks, particularly in the orbitofrontal region of prefrontal cortex. These findings could explain the impaired decision-making observed in substance-use disorders. We hypothesize that MOH could share fronto-striatal circuit dysfunction and relative decision-making deficit with addiction. We further examine whether this deficit is a persistent cognitive trait or a reversible consequence of medication overuse. This study shows a dataset of 50 patients with MOH before the detoxification. All patients underwent a complete neurological and psychiatric examination. Psychiatric examination consisted of a clinical interview, Structured Clinical Interview for DSM-IV TR Axis II Personality Disorders, Anxiety and Depression Hamilton Scales, Severity of Dependence Scale. The neurological examination included the migraine disability assessment questionnaire. Neuropsychological assessment of fronto-striatal circuits was investigated using the Iowa gambling task (IGT). Twenty patients monitored for any relapse into medication overuse had 12 months of follow-up. Our sample, characterized by high rates of disability and dependency-like behaviors, exhibited a deficit in IGT performance, indicating an overall impairment in decision-making. All the 20 patients showed neurological and psychiatric improvement at 12-month follow-up, notwithstanding the overuse relapse, but a persistent IGT deficit was found. To our knowledge this is the first study that assesses this cognitive function in patients with MOH. Medication-overuse headache seems to share a persistent decision-making deficit with substance abuse that confirms the orbitofrontal cortex hypometabolism described in literature from a neuropsychological perspective. Looking at these shared neurocognitive features, our results suggest that MOH could belong to the addiction spectrum. Fronto-striatal dysfunction could be a premorbid psychobiological condition of vulnerability explaining the clinical onset of medication overuse and recurrent relapses. We propose that IGT could be used to identify chronic migraine patients with higher risk for medication overuse and relapse.

ABSTRACT

OBJECTIVE: The primary goal was to identify risk factors for post-surgical depression in subjects operated on for drug-resistant epilepsy. Secondary goals were to confirm the high rate of depression in subjects suffering from epilepsy (prior to surgery) and to look for first post-surgical depressive episode. METHODS: Case series study of 150 subjects surgically treated for partial epilepsy (side of surgery: 72 right, 78 left; site of surgery: 97 Unilobar Temporal, 17 Unilobar Frontal, 14 Posterior, 22 Multilobar). All subjects routinely had three psychiatric evaluations: before surgery (baseline) and at 6 and 12 months after surgery. Psychiatric diagnoses were made according to DSM-IV-TR criteria. Bivariate (Fisher exact test and Kruskal-Wallis rank sum test) and multivariate (logistic regression model fitting) analyses were performed. RESULTS: Thirty-three (22%) subjects had post-surgical depressive episodes, 31 of them in the first 6 months. Fourteen out of 33 experienced depression for the first time. Post-surgical depressive episodes are not associated with gender, outcome on seizures, side/site of surgical resection, histological diagnosis, psychiatric diagnoses other than depression. Depressive episodes before surgery and older age at surgery time are risk factors for post-surgical depression (p= 0.0001 and 0.01, respectively, at logistic regression analysis). No protective factors were identified. CONCLUSIONS: Our data show that lifetime depressive episodes and older age at surgery time are risk factors for postsurgery depression. Moreover, a prospective study could be useful in order to assess whether depression is really a consequence of surgery.

ABSTRACT

Screening of headache patients for psychiatric disorders is needed, because of the well-known high rates of comorbidity with depression and anxiety. Screening for both depression and anxiety is highly advisable in order to identify subjects who need psychiatric consultation and therapy. Screening tools for depression and anxiety range from informal questions to self-report instruments to structured interviews and the choice is up to the clinician and the setting of the clinical evaluation. Data on psychiatric disorders and medication overuse are till now not consistent. The treatment of mood and anxiety disorders in headache patients needs to take into account the possible drug interactions with headache therapies. The collaboration between neurologists and consultation-liaison psychiatrists helps the identification of headache patients who need a psychiatric therapeutic program and follow-up.

ABSTRACT

AIM: The aim of this study was to estimate the prevalence of depressive symptoms in patients affected by subclinical hypothyroidism by means of Hamilton Rating Scale for Depression (HAM-D) and Montgomery-Asberg Depression Rating Scale (MADRS); to assess which depressive symptoms are prevalent in our population, with references to the factorialization of HAM-D by Cleary and Guy (1977); to verify whether levothyroxine replacement therapy alone can induce total remission of depressive symptoms. METHODS: The study enrolled 63 patients affected by subclinical hypothyroidism undergoing follow-up at the endocrinology service of San Paolo Hospital in Milan. All patients underwent an evaluation by means of HAM-D and MADRS scales and serum TSH, free T4, free T3, TPO-Ab and Tg-Ab levels were measured. RESULTS: We estimated a prevalence of depressive symptoms in our population of 63.5%. Concerning the qualitative assessment of psychiatric disturbances in the population we considered, our results showed that the most frequent symptoms were part of four factors, according to the Cleary and Guy factorialization of HAM-D: these factors are representative of anxiety and somatisation (factor I), cognitive impairment disturbances (factor III), psychomotor retardation (factor V) and sleep disorders (factor VI). Levothyroxine replacement therapy alone wasn't effective in inducing total remission of depressive symptoms. CONCLUSION: This study suggests the importance of a psychiatric evaluation in patients affected by subclinical hypothyroidism.

ABSTRACT

Patients suffering from schizophrenia have an impaired meta-representation also known as Theory of Mind (ToM). Moreover, the presence of delusions or other positive symptoms of schizophrenia has been correlated to poor ToM performances. Lack of insight is a common symptom of schizophrenia and can be considered a critical manifestation of impaired ToM abilities. In particular, the present study addresses the role of perspective ToM ability in schizophrenic patients. Thirty severely delusional schizophrenic patients completely lack insight when interviewed about their delusions. Seven subsequently gain insight about their mental state when perspective is shifted from the first person to third person. These data suggest that in some delusional schizophrenic patients, it may be possible to gain access to and modify their mental states.

ABSTRACT

OBJECTIVE: To verify the association of ribosomal anti-P antibodies (anti-P), as detected by a sensitive ELISA, with serological findings and clinical manifestations, including neuropsychiatric involvement evaluated according to the American College of Rheumatology (ACR) nomenclature, in a large cohort of patients with systemic lupus erythematosus (SLE). METHODS: Anti-P were evaluated in the serum of 149 consecutive Italian SLE patients by an ELISA using a multiple antigen peptide carrying four copies of a common P0, P1 and P2 epitope. A complete laboratory evaluation and clinical examination were performed in each patient. In addition, all patients underwent an accurate neuropsychiatric and neuropsychological assessment performed by trained specialists according to the 1999 ACR suggestions. RESULTS: Serum anti-P were detected in 18/149 patients (12.1%). The anti-P prevalence was similar (11.7%) when the analysis was performed in a larger series of sera including 82 additional SLE patients, who were not included in the clinical study. The age of anti-P-positive patients at disease onset was less than 33 yr and, in comparison with the anti-P-negative patients, these patients showed more active disease activity and a higher prevalence of photosensitivity and malar and discoid rash. A strong association between IgG anticardiolipin antibodies and anti-P was also found. However, anti-P were associated with neither neuropsychiatric syndromes nor cognitive impairment. CONCLUSION: This study does not seem to confirm the described association of anti-P with SLE neuropsychiatric manifestations. However, it supports the anti-P association with different skin manifestations as well as the presence of anticardiolipin in a subset of patients with SLE characterized by early disease onset.

ABSTRACT

OBJECTIVE: To verify whether features of CNS involvement can be detected in SLE patients without overt neuropsychiatric manifestations. METHODS: 114 SLE patients who had never received a diagnosis of neuropsychiatric lupus (never-NPSLE) were studied and compared to 65 SLE patients with known neuropsychiatric involvement (NPSLE). The study relied on evaluation of neurocognitive functions by means of a battery of neuropsychological tests, on psychiatric and neuropsychological assessments and on neuroimaging studies (computed tomography, magnetic resonance, single photon emission computed tomography (SPECT)). RESULTS: Clinical features, including disease duration/activity and pharmacological therapy, of never-NPSLE and NPSLE patients were similar. Short-term and long-term memory, visuo-spatial and verbal information processing were similarly compromised in never-NPSLE and in NPSLE patients; only attention was significantly more compromised in NPSLE patients. Psychiatric morbidity was higher than expected in never-NPSLE patients, although less than in the control neuropsychiatric group. Ischemic lesions, multiple small high intensity lesions and cortical atrophy, detected by CT and MR scans, as well as abnormal SPECT were also frequently detected in never-NPSLE patients. Interestingly, left parietal and occipital area hypoperfusion by SPECT was significantly more frequent in the patients with impaired visuo-spatial intelligence and short-term memory. CONCLUSIONS: Most abnormalities detected by available diagnostic tools and characteristics of neuropsychiatric SLE are also present in non-symptomatic patients. They may derive from an unexpected widespread involvement of the CNS and are not per se sufficient, in the absence of clinical manifestations, for a diagnosis of neuropsychiatric SLE.

ABSTRACT

Several researchers have underscored the importance of precise characterization of eye-tracking dysfunction (ETD) in patients with schizophrenia. This biological trait appears to be useful in estimating the probability of genetic recombination in an individual, so it may be helpful in linkage studies. This article describes a nonlinear computational model for using ETD to identify schizophrenia. A back-propagation neural network (BPNN) was used to classify schizophrenia patients and normal control subjects on the basis of their eye-tracking performance. Better classification results were obtained with BPNN than with a linear computational model (discriminant analysis): a priori predictions were approximately 80 percent correct. These results suggest, first, that eye-tracking patterns can be useful in distinguishing patients with schizophrenia from a normal comparison group with an accuracy of approximately 80 percent. Second, parallel distributed processing networks are able to detect higher order nonlinear relationships among predictor quantitative measurements of eye-tracking performance.

ABSTRACT

This study used eye tracking movement tests to examine the relationships between frontal field functions and clinical features. Smooth pursuit and voluntary saccadic eye movements were recorded and analyzed in 34 delusional disorder (DD) patients and in 40 normal subjects. The DD group differed significantly from the group of normal subjects in some eye tracking performances. As reported in our previous study (Gambini et al., 1993), DD patients showed abnormalities of voluntary saccadic eye movements. In this study, we also found abnormal smooth pursuit eye movements, indicating a cerebral dysfunction similar to those detected in schizophrenic patients. Moreover, normal smooth pursuit eye movement performance in DD patients was related to remitted depressive mood and probably to benefit from antipsychotic medications, thus supporting the idea of the biological and clinical heterogeneity of DD.

ABSTRACT

Recent studies in the literature point out that HIV-infected subjects are affected by depression with a relatively high frequency. The aim of this study was to assess the efficacy and tolerability of paroxetine for the treatment of depression in the context of HIV infection. 15 HIV-infected subjects (10 patients with a major depressive episode and 5 patients with an adjustment disorder with depressed mood, according to the DSM IV diagnostic criteria) were administered paroxetine at a daily dosage of 20 mg. Depressive symptomatology was monitored by means of the Hamilton Rating Scale for Depression (HAM-D) at the time of enrollment and 2 weeks, 4 weeks, and 6 weeks later; at the same times adverse effects were recorded. 14 patients completed the study, and all of these recovered from depression; HAM-D mean scores significantly improved from baseline to final assessment, both when all subjects were considered (ANOVA for repeated measurements: p < or = 0.0001) and when only patients with a major depressive episode were included in the statistical analysis (ANOVA for repeated measurements: p < 0.0001). No significant adverse effects were recorded. Because of its efficacy and good tolerability paroxetine seems to be suitable for the treatment of depression in the context of HIV infection.

ABSTRACT

Several authors have investigated the presence of thought disorder in psychiatric patients using different reliable methods. Under the hypothesis of a genetic predisposition to thought disorder, the degree and quality of thought disorder have also been studied in populations at a high risk for psychosis, in particular for schizophrenia. As a result, an increasing incidence of thought disorder was detected in relatives of schizophrenics. To account for the thought disorder also found in normal subjects, researchers propose that thought disorder exists in normal subjects on a continuum with schizophrenic patients. In the following report, we evaluated the inherited component of thought disorder in normal subjects, using a sample of 25 normal twin pairs, 16 monozygotic and 9 dizygotic twin pairs. We applied the Thought Disorder Index (TDI) to assess disordered thinking, genetic estimates were made with classical methods, controlling for environmental sources of variability where possible. Our findings suggest a strong additive genetic component for the global TDI rating variable, with a heritability estimate approaching 80-90%. New approaches in neuropsychology and neuropsychiatry-based on genetic methodologies should further define the cerebral physiology responsible for disordered thinking.

ABSTRACT

All the HIV-infected patients having referred to our Liaison Psychiatry Service between October 1992 and June 1994 were considered in this study. Seventy patients underwent psychiatric assessment and medical/neurological evaluation. Forty-seven of these patients were also subjected to cognitive/neuropsychological examination by means of the Milan Overall Dementia Assessment (MODA). Depressive episodes, adjustment disorders and substance abuse were the most frequently encountered diagnoses. Taking into account neuropsychological data, we found that symptomatic patients performed worse on tests than did asymptomatic ones.

ABSTRACT

BACKGROUND: The presence of psychiatric disorders (according to DSM-III-R), the discriminating power of a psychiatric structured interview, and sleep monitoring were investigated in psychophysiological insomnia. METHOD: Forty young (20-40 years old) patients, selected for putative psychophysiological insomnia, underwent a psychiatric structured interview and home ambulatory sleep monitoring for 2 nights. The results were compared with those of a group of nine young normal sleepers. RESULTS: 48% of the insomniacs showed some psychiatric disorders, while 52% did not meet DSM-III-R criteria for a psychiatric diagnosis. Both groups, but not the controls, showed a slight first-night effect in the sleep analysis. The sleep structure of all insomniacs was found to be disturbed, mainly in sleep continuity, but essentially the two groups showed no significant differences. When we used a stepwise logistic regression analysis, the number of sleep stage shifts (indicating sleep instability) was the best variable in discriminating the insomniacs from controls, but not the patients with psychiatric disturbances from those without psychopathologies. CONCLUSION: The evaluation of young insomniacs with a structured psychiatric interview rather than with ambulatory sleep monitoring seems to be most useful in discriminating between patients with only psychophysiological insomnia and patients with both insomnia and an associated diagnosis of another mental disorder.

ABSTRACT

The aim of this study was to evaluate the WCST, a task linked to the frontal (prefrontal) cortex, in normal twins to detect an inherited component of frontal lobe function. The WCST scores of 15 monozygotic (MZ) twin pairs, 9 dizygotic (DZ) twin pairs, and 15 unrelated control pairs were used to compute genetic estimates. No significant differences were detected between MZ, DZ and control groups intrapair correlation coefficients. No significant heritability estimates different by zero were computed. The frontal lobe function measured by WCST performance in normal twins does not seem to have a high degree of genetic component, and larger samples of twins are required to detect low genetic effects. The possible implications of such results about the genetic predisposition of frontal deficit in schizophrenia have been discussed.
