ABSTRACT

Patients with epilepsy experience stigmatization quite often. Studies investigating stigmatization perceived by patients with epilepsy in Turkey are limited in number. In this study, we aimed to understand the relationship between stigmatization and psychopathology and also to identify the effects of stigmatization on the quality of life in epilepsy. Patients completed a socio-demographical data form and epilepsy information form. They were evaluated in terms of psychiatric diagnosis using SCID I and they were asked to complete SCL-90 R, Epilepsy Stigmatization Scale and SF 36. The percentages of patients who did and did not report perception of stigmatization were similar in the study group. Depression was the most common diagnosis followed by anxiety disorder. In comparison to patients who did not feel stigmatized, patients who reported perceived stigmatization had a higher frequency of generalized tonic clonic seizures and injuries during seizures and more frequently missed taking their medication. They also showed higher rates of both suicide attempts and psychopathology as evidenced by a higher rate of psychiatric diagnosis and higher score in all the subscales of SCL 90. With regard to their quality of life they were observed to be more disabled in the physical functioning, general health perception, vitality, social role functioning and mental health dimensions. A logistic regression analysis revealed that stigmatization was best predicted by three variables: history of suicide attempts, receiving a psychiatric diagnosis and higher score in SCL90PST. Our study has shown that psychopathology is a more significant predictor of stigmatization than the other variables related with seizure control.

ABSTRACT

OBJECTIVE: The relationship between homocysteine (HCY) levels and cognitive impairments, particularly executive functions in bipolar disorder (BD), has recently been investigated. However, conflicting results were reported. The aim of the present study is to investigate changes in serum HCY, methionine, vitamine B12 and levels in BD patients are relative to controls and to investigate the relationship between HCY, methionine, vitamin B12, and folate levels and clinical features, cognitive functions and psychosocial functioning in euthymic BD patients and controls. METHODS: Sixty BD type I euthymic patients and twenty controls were assessed with Global Assessment of Functioning and a battery of neuropsychological tests including the Wisconsin card sorting test, the Rey's auditory verbal learning test, the Cancellation test, Trail making test A, Trail making test B, and the Stroop test. HCY, vitamin B12, methionine and folate levels were measured together after collecting blood samples from both patient and controls. RESULTS: Mean serum methionine concentration was different between groups. Low serum methionine was found to be a predictor of BD. However, a statistically significant difference was not detected between groups for mean serum values of HCY, folate, or vitamin B12. HCY levels showed a positive correlation with illness duration, the number of total episodes, and the number of manic episodes. A significant correlation was not found between HCY, methionine, folate, B12 levels with cognitive functions and functioning in the BD group. CONCLUSION: Low serum methionine was found to be a predictor of BD, a condition which can lead to a decrease in SAM synthesis and thus to a variety of complications in methylation reactions. Additional studies are needed to clarify the impact of single carbon metabolism on BD.

ABSTRACT

OBJECTIVE: Tumor necrosis factor-alpha (TNF-α) may play an important role in bipolar disorder (BD) pathogenesis. There is only one study about a relationship between TNF-α levels and cognitive impairments in BD. The aim of the present study was to see whether TNF-α, soluble P55 TNF receptor (sTNFR1), and soluble P75 TNF receptor (sTNFR2) levels in BD patients are different from controls and to investigate the relationships between the levels of TNF-α, sTNFR1, and sTNFR2 and the cognitive functions in euthymic BD patients and controls. METHODS: We assessed 54 BD type I patients and 18 controls by using a battery of neuropsychological tests. Serum TNF-α levels were measured using a commercially available enzyme-linked immunosorbent assay, whereas serum sTNFR1 and sTNFR2 levels were measured using a commercially enzyme-amplified sensitivity immunoassay kit. RESULTS: We found that levels of sTNFR1 and sTNFR2 in BD patients were different from controls. No difference was detected between the BD group and the control group for levels of TNF-α. TNF-α level was found to have a negative correlation with the delayed recall in RAVLT. CONCLUSIONS: High levels of sTNFR1 and sTNFR2 in euthymic patients showed that it may support that proinflammatory process continues in euthymic period. This is the first study which showed increased sTNFR2 levels in euthymic period, which could be interpreted as a compensatory mechanism and again the first which deals with verbal memory.
