[Neuropsychological study of the schizophrenic defect]

Area of Science:

• Neuropsychology
• Neurology
• Brain Imaging

Background:

• Neuropsychological disorders can stem from various brain dysfunctions.
• Understanding the specific patterns of these disorders is crucial for diagnosis and treatment.
• Previous research has explored the link between cognitive deficits and brain structure.

Purpose of the Study:

• To classify and describe distinct variants of neuropsychological syndromes.
• To investigate the correlation between the severity of neuropsychological deficits and anergy.
• To compare neuropsychological findings with computer-aided tomography (CT) data.

Main Methods:

• Utilized A. R. Luria's neuropsychological examination method.
• Examined 30 patients (18 men, 12 women) aged 17-47 years.
• Correlated neuropsychological data with computer-aided tomography (CT) scans.

Main Results:

• All patients exhibited deficiencies in activation components and higher regulatory functions.
• Three variants of neuropsychological syndromes were identified based on affected brain regions (frontal, fronto-subcortical, and widespread cortical).
• A strong positive correlation (r = +0.75) was found between neuropsychological disorder intensity and anergy magnitude.

Conclusions:

• Neuropsychological syndromes present with distinct patterns related to specific brain system dysfunctions.
• Anergy levels significantly correlate with the severity of observed neuropsychological impairments.
• While CT scans showed no group differences initially, more severe structural changes were noted in patients with widespread cortical involvement and a history of perinatal harm.
