Summary

Schizophrenia patients show significant visual-motor impairments, including form distortion and rotation, compared to controls. The Bender-Gestalt Test effectively identifies these perceptual alterations in both acute and chronic schizophrenia.

Background:

Schizophrenia is a complex mental disorder affecting visual and motor functions.
Understanding these deficits is crucial for diagnosis and treatment monitoring.
The Bender-Gestalt Test is a widely used neuropsychological tool.

Purpose of the Study:

To investigate visual and motor function differences in chronic and acute schizophrenia patients compared to healthy controls.
To evaluate the utility of the Bender-Gestalt Test in detecting specific perceptual and motor deficits in schizophrenia.
To analyze parameters such as form distortion, rotation, integration, perseveration, use of space, subtle motricity, global score, and time.

Main Methods:

The study involved 26 chronic schizophrenic patients, 7 acute schizophrenic patients, and 26 normal controls.

Participants completed the Bender-Gestalt Test.

Performance was assessed based on specific parameters including form distortion, rotation, integration, perseveration, use of space, subtle motricity, global score, and time.

Main Results:

Highly significant differences were found in form distortion and rotation between chronic schizophrenic patients and controls.
Acute schizophrenic patients exhibited highly significant perseveration.
No significant differences were observed in integration and use of space among the groups. The global score showed significant differences between patient groups and controls.

Conclusions:

The Bender-Gestalt Test is effective in identifying alterations in perceptual closure and loss of objective structure in both acute and chronic schizophrenia patients.
Specific visual-motor deficits, such as distortion, rotation, and perseveration, are characteristic of schizophrenia.
These findings highlight the test's value in assessing cognitive and perceptual impairments associated with schizophrenia, even in patients undergoing neuroleptic treatment.
