Association between serum irisin concentration and ischemic stroke: From etiology to clinic.

Background: To investigate the relationship between irisin levels in serum and classification of subtype of acute ischemic stroke, National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Score (mRS) at the time of discharge from the hospital in Turkish patients who had their first acute ischemic stroke (AIS). Methods: Serum irisin levels were measured using enzyme linked immunosorbent assay (ELISA) 180 patients who applied to emergency department with the diagnosis of AIS from May 2021 to November 2021. Results: A significant relationship was found between serum irisin levels and ischemic stroke aetiological factors (TAOST) (p=0.017). Increased serum irisin levels were detected in patients without neurological deficits with localization value than those with it (p<0.01). Serum irisin levels also have a negative correlation with high-density lipoprotein (HDL) value in ischemic stroke (r: -0.272, p<0.01). Conclusions: High serum irisin levels found in patients with stroke attributed to small vessel disease and in patients with ischemic stroke in whom we did not find any neurological deficits with a localization value. The results of the study show that serum irisin levels have an important role in the etiology of ischemic stroke. Although the question how the irisin is involved in the course of ischemic stroke and what the clinical reflection has not been answered, these findings are a pioneering study on this subject.

Effect of alexithymia and difficulty of emotion regulation, neuroticism, low extraversion, and suicidality on quality of life in epilepsy.

OBJECTIVE: The objective of this study was to investigate alexithymia, emotion dysregulation, suicidality, and personality traits in people with epilepsy (PWE) and to evaluate their effects on quality of life. MATERIALS AND METHODS: Forty-six consecutive PWE and forty healthy control subjects (HC) were recruited for the study. Both PWE and HC were interviewed and completed the following questionnaires: Toronto Alexithymia Scale-20(TAS-20), Difficulties in Emotion Regulation Scale (DERS), Eysenck Personality Questionnaire, Suicidal Ideation Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, and Quality Of Life In Epilepsy-31. RESULTS: TAS-20 and difficulty identifying feelings which was the subgroup of TAS-20, scores of total and non-acceptance, goals, impulse, strategies, and clarity subgroups of DERS were statistically significantly higher in PWE (p = 0.01, 0.004, 0.01, 0.07, 0.009, 0.06, 0.01, respectively). Considering the personality characteristics, neuroticism was more common in PWE, while extraversion was less common. Suicidal ideation and anxiety scores were higher in PWE than HC (p = 0.02, p = 0.003). Anxiety, suicidal ideation, neuroticism, alexithymia and emotion dysregulation had a negative relationship on quality of life. (r = -0.54, p < 0.001; r = -0.54, p < 0.001; r = -0.62, p < 0.001; r = -0.32, p = 0.02; r = -0.52, p < 0.001). CONCLUSION: Difficulty identifying feelings, dysregulation of emotions especially nonacceptance, goals, impulse, strategies, and clarity are common in PWE. Anxiety, suicidal ideation, neuroticism, alexithymia, and emotion dysregulation had a negative impact on quality of life. Each of these are important for psychosocial wellbeing of our patients and must be questioned considering their effects on quality of life.

Recognition of emotional face expressions in patients with restless legs syndrome.

OBJECTIVE: Restless legs syndrome (RLS) is one of the commonest neurologic diseases. Along with sensory and motor symptoms, cognitive impairment and psychiatric features can be seen with RLS. The present study, was planned to look for evidence of cognitive impairment by evaluating facial emotion recognition (FER) in patients with RLS. METHODS: In this study, 80 patients with RLS and 50 healthy controls (HCs) were included. Demographic data were recorded. All patients with RLS and HCs were tested with Beck anxiety inventory (BAI), Beck depression inventory (BDI) and with Ekman's test for recognition of facial emotions. RESULTS: Sixty-three of the patients with RLS and 37 of the HCs were female. The mean age of the patients was 45.41 ± 8.24, and the mean age of HCs was 43.12 ± 10.35. The patients and HCs were similar regarding sex, age, educational status, and marital status. Patients with RLS had FER difficulties comparing HCs. There was a negative correlation between Ekman's test scores and BDI (r = -0.311, p < 0.001) and BAI scores (r = -0.379, p < 0.001). CONCLUSION: FER is an invaluable research topic regarding cognitive function in RLS, which may help us develop different perspectives in terms of revealing the pathophysiology and is very important for the well-being of the patients' social interactions.

Microstructural changes of basal ganglia in migraine with restless legs syndrome: findings from a neuroimaging study.

In this study, it is planned to investigate the integrity of the basal ganglia structures in migraineurs with restless legs syndrome (RLS) to explore this relationship. In this study, 58 patients who were diagnosed migraine and 51 healthy controls (HCs) were included. Patients diagnosed with migraine were divided into two groups: Group I (migraine without RLS) and Group II (migraine with RLS). The integrity of basal ganglia was evaluated with region of interest diffusion tensor imaging method which allows us to assess microstructural changes of the tissue. The mean age of the patients was 35.98 ± 7.92 years, and the mean age of the HCs was 33.84 ± 11.06. 84.5% (n = 49) of the patients were female and 15.5% (n = 9) were male. 82.4% (n = 42) of the HCs were female, 17.6% (n = 9) were male. The number of  the patients without RLS was 41 (Group I), and the number of the patients with RLS was 17 (Group II). When basal ganglia structures were compared between groups of the patients with and without RLS, the fractional anisotropy (FA) value of the left putamen differed (Group I: 0.30 ± 0.06 vs. Group II: 0.25 ± 0.7, p = 0.01). The significant relationship was found attack frequency and presence of RLS with left putamen FA values according to multiple regression analysis. It was determined in this study that the changes in the microstructure of putamen, one of the basal ganglia structures, may be associated with the presence of RLS in migraineurs.

Social phobia and its relationship with perceived epilepsy-associated stigma in patients with epilepsy.

Patients with epilepsy (PWE) might feel stigmatized due to the likelihood of having uncontrollable seizures and the possibility of their sudden occurrence in the community, which may lead to increased rates of social phobia in these patients. People with social phobia interpret others' attitudes toward them negatively and hence feel stigmatized. This vicious circle may be applied to PWE, reduces the quality of life and might cause them more challenging psychosocial problems than seizure management. We aimed to investigate the relationship between social phobia and stigmatization in PWE. Forty PWE and 40 age- and sex-matched healthy control subjects (HC) were included in the study. Liebowitz social anxiety scale (LSAS), Beck anxiety inventory (BAI), and Beck depression inventory (BDI)-II were administered to all participants. In addition to these, the stigma scale of epilepsy (SSE) was applied to the PWE, and the subcategory scores of this scale were calculated. The mean ages of the patient group and HC were determined to be 32.68 ± 10.67 and 33.80 ± 7.81, respectively (p>0.05). A significant difference was determined in the BDI-II, LSAS, and BAI scores of the patient group compared to HC (p<0.05). A significant correlation was found between scores of LSAS and SSE and this relationship continued regardless of depression levels (p<0.05). Our results demonstrate that social phobia is positively correlated with stigmatization in PWE. In PWE, psychiatric disorders are generally under-recognized and mistreated. Plus, it has a substantial impact on patients' quality of life. To achieve the social reintegration of these patients, comorbid psychiatric conditions of the disease and the factors associated with these conditions should be identified and treated.

Long term neurological sequela of isolated infarctions according to the topographic areas of thalamus

Background/aim: Thalamus infarctions presented with various clinical findings are considered to be related to classical and variative infarction areas. In our study, we aimed to compare the sequela clinical findings of patients with isolated thalamus infarction according to anatomical areas. Materials and methods: Seventy patients diagnosed with isolated thalamus infarction in our clinic between 2010 and 2020 were included in the study. The infarction areas of the patients were divided into groups by the radiologist, including the variative areas to the classical areas using magnetic resonance imaging. Neurological examinations were performed and recorded. Sequela clinical findings of the groups were compared. Results: The mean age of all patients was 64.49 ± 13.75 (range between: 33­81) years, and the female ratio was 52.9% (n: 33). Inferolateral area infarction was detected most commonly. The most common complaints were sensory complaints (48.6%), speech disorders (20%), limb weakness (15.7%). There were no significant association between the neurological examination findings of classical and variative area infarctions of patients whose most common admission complaint is sensory deficits (p < 0.05), and significant signs of cognitive impairment were detected in the anterior area compared to other areas (p < 0.001). It can be considered that cognitive impairment we detected in the anterior area developed due to its associations. Conclusion: In our study where sequela findings were evaluated, the absence of a significant difference in neurological examination findings can be explained by the decline of many acute clinical findings over time.
