This study has used neuropsychological tasks--Wisconsin Card Sort (WCST), Trail Making (TMT) A and B, Verbal Fluency, Digit Span--to compare acute and currently off-medication schizophrenics, patients with unipolar nonpsychotic major depression and healthy controls. Both patient groups differed significantly from healthy controls in their neuropsychological(More)
This study investigated the performance of individuals with familiar loading of schizophrenia (healthy siblings of schizophrenic inpatients) on three neuropsychological tasks assumed to require frontal lobe functions: Trail Making Test (TMT), verbal fluency and Wisconsin Card Sorting Test (WCST). Healthy siblings of schizophrenics differed in performance(More)
The Wisconsin Card Sorting Test (WCST) is a neuropsychological test, hypothesized to be an indicator of dorsolateral prefrontal cortex (DLPFC) functioning. The performance of schizophrenic patients in our sample (off medication) was worse than the performance of healthy controls in all variables of the WCST, including perseverative responses (PR) as well as(More)
Preclinical data indicated that seroquel (ICI 204 636), a dibenzothiazepine with 5-HT2 and D2-like receptor antagonistic properties, might be an effective antipsychotic agent, causing fewer extrapyramidal side effects than typical neuroleptics. In the present study, 12 patients suffering from schizophrenia or schizophreniform disorder with predominantly(More)
BACKGROUND In the treatment of panic disorder with agoraphobia, the efficacy of pharmacological, psychological and combined treatments has been established. Unanswered questions concern the relative efficacy of such treatments. AIMS To demonstrate that moclobemide and cognitive-behavioural therapy (CBT) are effective singly and more effective in(More)
Thirty-five schizophrenic patients in the early stages of illness, 26 of their healthy siblings, and 35 normal control subjects performed the Continuous Performance Test, Identical Pairs version (CPT-IP). Both schizophrenic patients and their siblings were significantly impaired in their attentional performance compared with normal subjects. These results(More)
In a search for an external validation of the negative syndrome construct and the attentional impairment item on Andreasen's scale, 49 unmedicated schizophrenic patients were administered the Span of Apprehension Test and a Continuous Performance Test with two levels of difficulty. This schizophrenic sample performed significantly more poorly on the(More)
To assess the frequency and quality of formal thought disorder in schizophrenic patients and their first-degree relatives, a consecutive series of 36 unmedicated patients, 20 siblings of these patients and 37 normal control subjects were examined with Holzman's Thought Disorder Index (TDI). As a proof of the internal validity of this tool, the patients(More)
Schizophrenia is associated with enduring deficits in neuropsychological functioning. It is widely undecided if the various aspects of neuropsychological impairment are a consequence of the disorder or if they are also present premorbidly and in populations at increased risk for schizophrenia (vulnerability markers). Neuropsychological deficits in healthy(More)
Deviant response patterns in experimental reaction time paradigms in schizophrenic probands are well documented. Although simple reaction times are strongly influenced by the current psychopathological status of the proband (e.g. florid psychotic patients versus remitted patients) these influences are less clear for measures obtained from more complex(More)
