Abstract [en]

Neurocognitive deficits are considered a core feature of schizophrenia.

Deficits covering a wide range of functions have been well

documented. However there are still relatively few longitudinal

studies regarding the long-term development of neurocognitive

impairment. The current study examined the effect of time in

schizophrenic patients and controls concerning cognitive functions. A

neurocognitive test-battery was administered on two occasions to 36

schizophrenic patients and 46 healthy controls with approximately 4.5

year interval. Results showed that schizophrenic patients performed

significantly worse on all measures on both occasions. No significant

decline was found over time for either group except for on Trail

Making Test, part B. Improvement on Continuous Performance Test

was found for affected patients and improvement on Rey Auditory

Verbal Learning Test was found for controls. Age was related to

outcome in controls and education was related to outcome in patients.

The conclusion is drawn that neurocognitive measures are relatively

stable over 4.5 years in patients with schizophrenia, in line with earlier

research. The authors discuss the impact of age and education and

limitations of the study.
