Personality change after 'flow diverter implantation' for intracranial aneurysm in a patient with stroke: A case report.

OBJECTIVE: This study aimed to present a patient with psychiatric symptoms that occur after flow diverter stent placement in a posterior communicating artery (PComA) aneurysm in a patient. DESIGN: A case study. METHOD: We performed cranial magnetic resonance imaging (MRI), magnetic resonance angiography, computed tomography angiography, neuropsychological tests, Levenson Self-Report Psychopathy Scale (LSRP), and a 25-item version of the Wender Utah Rating Scale (WURS-25). The patient's recent MRI was compared with previous MRIs. Neuropsychological testing consisted of a clinical interview, clinical assessment of frontal lobe syndrome, and tests evaluating the prefrontal cortex functions (Wisconsin Card Sorting Test-128 card version and Iowa Gambling Test). RESULTS: Our results showed that the patient's personality change and psychiatric symptoms occurred after the stent placement. Symptoms were still present at evaluation two and a half years after stent placement. CONCLUSION: The study demonstrates personality changes and psychiatric symptoms that might occur as complications following the placement of a flow diverter for incidentally detected aneurysm.

Emotional context effect on recognition of varying facial emotion expression intensities in depression.

BACKGROUND: Previous research has indicated that Major Depressive Disorder (MDD) patients have deficits in the process of facial emotion recognition. In most of these studies, isolated emotional faces were used, and the effect of the surrounding context of the face was neglected. We aimed to investigate how context emotion (sad or happy) affects facial emotion recognition and whether this effect is different in depressive individuals compared to the control group. METHODS: Happy, sad, neutral facial expressions with congruent and incongruent visual contexts were presented to 51 MDD patients and 42 matched healthy controls. Emotional facial expressions are presented as morphs gradually expressing happiness or sadness with 40% and 80% intensity levels. Mean reaction time, mean accuracy rate, and mean emotion intensity rating score was calculated for each condition. RESULTS: The performances on facial emotion intensity rating and accuracy rate were similar between MDD patients and controls. MDD patients were slower to recognize all facial emotions and to recognize facial emotions with emotionally incongruent backgrounds compared to congruent ones. LIMITATIONS: Antidepressant therapy of patients might have affected our results. CONCLUSIONS: Emotional contextual features have an important role in facial emotion recognition but this effect is independent of depression. Longer reaction time in depression may be related to some cognitive impairments.

Burnout in Healthcare Professionals During the Covid-19 Pandemic in a Tertiary Care University Hospital: Evaluation of the Need for Psychological Support. / Üçüncü Basamak Bir Üniversite Hastanesinde Covid-19 Pandemisinde Saglik Çalisanlarinda Tükenmislik: Psikolojik Destek Ihtiyacinin Degerlendirilmesi.

OBJECTIVE: Anxiety, stress and burnout are observed in healthcare workers during the Covid-19 pandemic. This study aimed to determine the levels of anxiety and burnout and related risk factors in the healthcare workers and assistant personnel at a tertiary referral university hospital. METHOD: Hospital Anxiety Depression Scale (HADS), Maslach Burnout Inventory (MBI) and a sociodemographic questionnaire were delivered on-line to all employees of our hospital. 683 individuals were to the study who completed and returned the forms between April 15-30, 2020. RESULTS: Stress, depression and anxiety levels were significantly higher in nurses. Emotional burnout and depersonalization symptoms were higher and personal accomplishment scores were lower in resident physicians and nurses in comparison to the other groups. Being single, having a child and living away from home were factors underlying the burnout severity. Frontline work in the Covid-19 clinics did not affect the levels of anxiety, stress and depression. On the basis of the cut off points of the HADS scores; anxiety disorder (OR: 7.19) and depression (OR 3.43) were the most relevant risk factors for emotional exhaustion. Anxiety disorder was also the main risk factor for depersonalization. Depersonalization was 2.7-fold more among the nurses complaining of being overworked. Social support from the work environment and the family was protective against depersonalization. CONCLUSION: Covid-19 pandemic has adversely affected the wellbeing of healthcare workers. The presence of depression and anxiety increased the risk of burnout. Social support can be expected to protect against burnout. It is, therefore, of great importance to implement urgently effective psychosocial and organizational interventions in order to protect the mental health of healthcare workers and to prevent burnout.

Gray matter changes in patients with deficit schizophrenia and non-deficit schizophrenia.

OBJECTIVES: Reduced gray matter volume is a frequently reported finding in brain imaging studies performed with schizophrenia patients. Some studies suggest a probable link between the negative symptoms of schizophrenia and gray matter loss; however, some of the negative symptoms observed in schizophrenia patients are not primarily linked to the core of schizophrenia. This study aimed to compare gray matter volumes in patients with primary negative symptoms (deficit schizophrenia [DS]), non-DS (NDS) patients, and healthy controls. MATERIALS AND METHODS: The study included 11 DS patients, 18 non-DS patients, and 17 healthy controls. Magnetic resonance imaging (MRI) was performed using a 1.5 Tesla MR unit. The Schedule for Deficit Syndrome (SDS) was used to determine which patients were DS and non-DS. MR images were compared using voxel-based morphometry (VBM) analysis. RESULTS: Contrary to expectations, no evidence to support less gray matter in DS patients than in NDS patients was observed. Furthermore, NDS patients had less gray matter volume in several brain regions (frontal and temporal cortices) than did the DS patients. All patients had perisylvian gray matter volume deficits, though the NDS patients had more widespread volume deficiencies. CONCLUSION: No evidence to support the hypothesis that DS patients have less gray matter volume than those of NDS patients was observed. On the contrary, DS patients had more gray matter volume in some regions; the differences observed in gray matter volume in these brain regions between the 2 patient groups may be responsible for the differences in their clinical manifestations.

The disrupted connection between cerebral hemispheres in schizophrenia patients: a diffusion tensor imaging study.

AIM: In schizophrenia, the disruption of the communication between two brain hemispheres has not been shown clearly in the anatomical aspect despite other studies with different modalities suggested so. In this study, the structural integrity and the variables affecting the structural integrity of the corpus callosum, which is the main connection between two hemispheres, was investigated via diffusion tensor imaging (DTI). METHODS: The participants were evaluated by SCID-I and symptoms of the patients were assessed with PANSS. DT images of 25 schizophrenia patients and 17 healthy volunteers were acquired via 1.5 T MR. Fractioned Anisotropy (FA) values of two groups, measured on the DT images, were compared. RESULTS: It was found that fractioned anisotropy (FA) values were lower in the genu of the patients than the healthy controls; however, there was no difference between the FA values of the patients and the controls in the splenium. Moreover, a significant negative correlation between the splenium FA values and the antipsychotic medication doses; and a trend level negative correlation of splenium FA and PANSS scores were found. CONCLUSION: Corpus callosum is the most important structure that connects two frontal lobes. The hypothesis that posits the fundamental role of the disconnection of frontal lobes in schizophrenia is supported by the findings of this study.

[Small frontal gray matter volume in first-episode depression patients]. / Ilk Atak Depresyon Hastalarinda Azalmis Frontal Korteks Hacimleri.

OBJECTIVE: Brain imaging studies have shown that depressed individuals suffer from inadequate frontal lobe functions vis à vis smaller frontal lobes. The effects of depression's recurrent nature and long-term antidepressant treatment are not definitely known. This study aimed to examine frontal lobe volume at the onset of clinical depression by including first-episode drug-naive depressed patients. METHOD: The study included 23 first-episode drug-free major depression patients diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and 28 healthy age- and sex-matched controls. Cranial magnetic resonance (MR) images were obtained in both groups using a 1.5 Tesla device. Gray and white matter volumes in the frontal lobes were measured using the Medical Image Processing Analysis and Visualization (MIPAV) computer program. RESULTS: Frontal gray matter volume in the patients was lower than that in the control group. White matter and total intracranial volume did not differ between the 2 groups. Small gray matter volume was not correlated with the duration or severity of illness. CONCLUSION: The results of this study indicate that frontal lobe gray matter volume is low in first-episode depressed patients and is independent of both illness severity and duration. This result suggests that the observed changes in the frontal lobe could have occurred before the clinical symptoms of depression were observed.
