Öğe Adult attention-deficit hyperactivity disorder in patients with bipolar I disorder in remission: Preliminary study(Blackwell Publishing, 2006) Tamam, Lut; Tuglu, Cengiz; Karatas, Gonca; Ozcan, SevilayAttention-deficit hyperactivity disorder (ADHD), a syndrome that typically first appears in early childhood, can occur in individuals of all ages. Prospective studies have demonstrated that at least half of children diagnosed as having ADHD continue to suffer the symptoms of this disorder in their adult life with significant impacts on their social status, achievement level and sense of well-being. The purpose of this preliminary study was to determine the rate of ADHD in patients with bipolar disorder (BD) and to examine the effects of comorbid ADHD on several clinical and sociodemographic variables of bipolar patients. Forty-four BD-I patients followed up in psychiatric outpatient clinics in two university hospitals, were assessed for the presence of adult ADHD according to DSM-IV. All patients also completed the Wender Utah Rating Scale for objective evaluation of ADHD. Of 44 patients with BD-I, only seven (15.9%) fulfilled criteria for a diagnosis of adult ADHD. Bipolar disorder-I patients with comorbid ADHD were more likely to be female, and have more affective episodes (especially depressive episodes) than bipolar patients without comorbid ADHD. Age at onset of affective illness was not significantly different between the two groups. In line with results of several previous reports, the present study also showed higher prevalence of ADHD in patients with BD-I than in normal population. A higher number of affective episode in patients with comorbid ADHD may suggest a more severe clinical course of BD in these patients. A larger group of samples is required to clarify the exact association and interaction between these two clinical entities.Öğe The relation of homocysteine levels with deficit syndrome and working memory in schizophrenic patients(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2011) Tuglu, Cengiz; Ozcan, Sevilay; Erdogan, Yasin; Sut, Nejdet; Vardar, Erdal; Abay, ErcanObjective: There are many theories about etiology of schizophrenia and many studies are going on to find out a biologic determinant specific for schizophrenia. Single carbon metabolism theory has been suggested for the etiology of schizophrenia. There are also many data about a defect in homocysteine metabolism and increased levels of homocysteine in schizophrenic subjects but the correlation of hyperhomocysteinemia with the clinical reflections and symptom dispersion of schizophrenia has not been studied yet. Methods: For forty-one schizophrenic patients, clinical assessments were performed. The patients were divided into two groups, as deficit syndrome group and nondeficit syndrome group, using the deficit syndrome chart. Various test batteries have been applied to all patients to asses the clinical symptomatology and working memory. Serum homocysteine, vitamin B-12, and folic acid levels were measured concurrently. Results: Homocysteine levels were higher in the study group and mild to moderate hyperhomocysteinemia has been observed at the sample group independent folic acid levels. The homocysteine levels and clinical scale scores did not correlate statistically but folic acid levels did with negative symptomotology and functional disturbance. Conclusion: Serum homocysteine levels were elevated in both male and female schizophrenia patients. Hyperhomocysteinemia with the deficit syndrome as well as working memory did not show a statistically significant correlation. (Anatolian Journal of Psychiatry 2011; 12:169-176)
