Objective: Although previous studies have shown that the theory of mind (ToM) ability is impaired in Asperger's Syndrome (AS) and in schizophrenia, few controlled studies compared the ToM performance between the two disorders. Besides, the relationship between the degree of ToM impairment and symptom dimensions is unclear, and presence of ToM impairment in remitted patients with schizophrenia is controversial. Here, we tested the hypothesis that schizophrenia patients with prominent negative symptoms were closer to AS patients and different than schizophrenia patients without prominent negative symptoms and healthy controls in terms of ToM functioning.

Objectives: It has been shown that autistic spectrum patients have impaired theory of mind (ToM) performance; however, no study has investigated the relationship between ToM performance and brain neurochemistry in these patients. The present study aimed to investigate the correlations between dorsolateral prefrontal cortex (DLPFC) and anterior cingulate cortex (ACC) N-acetyl-aspartate (NAA)/choline (Cho), NAA/creatine (Cr), and Cho/Cr values based on H magnetic resonance spectroscopy and ToM tests.

Method: The study sample included 13 adult, right-handed, Caucasian males with Asperger’s syndrome (AS) (age range: 17–37 years) and 20 controls matched by age, gender, handedness, and Wechsler Adult Intelligence Scale, Revised (WAIS-R) full-scale IQ scores.

Objectives: Patients with bipolar disorder have been reported to have neurocognitive deficits; however, it is not known whether the cognitive dysfunctions are state-dependent or a stable trait. Lithium and valproate, 2 of the most widely used mood stabilizers in the treatment of bipolar disorder, have also been associated with cognitive impairment. However, the degree and pattern of neurocognitive impairment in euthymic bipolar patients on either monotherapy with lithium or valproate have not been compared before in depth.

Findings about the impairment of executive functions in schizophrenia are not conclusive. The authors hypothesized that the severity of the impairments in the abilities that comprise EF might be different. Forty patients were assessed with a comprehensive battery that included four measures of executive functions and were compared with 60 healthy subjects.

Objective: To determine reliability and validity of Turkish form of the 25 item Wender Utah Rating Scale (WURS), which is designed as an aid for diagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults.

Method: The scale was administered to 59 patients who were diagnosed as having ADHD according to DSM-IV criteria after comprehensive psychiatric and neuropsychological assessments in outpatient clinics of University of Ankara Medical School, Department of Psychiatry. Control groups consisted of 59 patients with depression, 44 patients with bipolar affective disorder in remission, and 145 healthy controls.

The Scale for the Assessment of Negative Symptoms (SANS) attention subscale has been found valid and reliable by some studies; however, there is some evidence to the contrary. We hypothesized that social inattentiveness (SANS 22) and inattentiveness during mental status testing (SANS 23) might be describing discrete constructs, and this dissociation might be a source of controversy. Thirty-five patients with DSM-IV schizophrenia were assessed by the Scale for the Assessment of Positive Symptoms (SAPS), SANS and a neuropsychological battery.
