OBJECTIVE Follow-up studies of cognitive functions of poor-outcome (long-term institutionalized) elderly patients with schizophrenia have demonstrated deterioration over time, while stable cognitive functions over time have been reported for younger, better-outcome schizophrenic patients. This study examined whether cognitive changes in elderly(More)
BACKGROUND Individuals with schizotypal personality disorder (SPD) share cognitive deficits with schizophrenic patients, suggesting that these deficits represent a core feature of the schizophrenia spectrum. We investigated the neuropsychological profile in SPD patients compared with two comparison groups: healthy volunteers (HV) and patients who met(More)
Gender effects have been reported quite consistently in schizophrenia, with male patients having an earlier age of onset, poorer functional outcome, greater negative symptoms and cognitive impairment, and less severe positive symptoms. Because age of onset, cognitive impairments, and negative symptoms are all correlated with poorer functional status, it is(More)
Cognitive dysfunction is increasingly being recognized as a major contributor to the adaptive impairment seen in most patients with schizophrenia. Reported here is a prospective longitudinal evaluation of the relationship between cognitive and adaptive functioning in elderly patients with schizophrenia. It was hypothesized that baseline cognitive and(More)
This study examined the relationship between clinical rating of cognitive symptoms and performance on neuropsychological tests in acute and chronic samples of patients with schizophrenia. Two separate studies examined patients who varied widely in their lifetime functional outcome, including 263 elderly poor-outcome inpatients and 20 acutely admitted(More)
BACKGROUND Attentional deficits are prominent in schizophrenia, and skill learning is impaired. Novel antipsychotic treatment has been reported to improve certain cognitive skills in schizophrenic patients, but no information is yet available about the effect of newer medications on skill learning. METHODS Clinically stable patients with schizophrenia(More)
BACKGROUND Our study examined the differential performance of cognitive skills in geriatric, cognitively impaired schizophrenic patients (n = 165) with a lengthy course of institutional stay and a poor overall functional outcome. Their relative deficits were compared with a sample of healthy elderly individuals. METHODS Schizophrenic patients were matched(More)
The authors assessed whether cognitive functioning and negative symptoms are related to functional outcome across severity of negative symptoms and examined relationships between symptom domains in patients with high versus low negative symptom severity. The interrelationships between cognitive functioning and functional skills in poor-outcome geriatric(More)
