Studies of higher nervous activity in functional phychoses

Summary
Psychiatric illnesses offer insights into normal psychology. Research highlights how disturbances in unconditional reflex activity are key physiological markers in manic-depressive and schizophrenic psychoses.
Area of Science:
- Psychophysiology
- Experimental Psychology
- Psychiatric Research
Background:
- Psychiatric illnesses as natural experiments elucidating normal psychological processes.
- Reactive psychoses exhibit psychogenic origins with disturbances in higher nervous activity.
- Unconditional reflex activity is largely unaffected in reactive psychoses, with psychodynamic complexes playing a significant role.
Purpose of the Study:
- To investigate the physiological underpinnings of different psychiatric disorders, specifically manic-depressive and schizophrenic psychoses.
- To explore the role of unconditional reflex activity and psychodynamic factors in psychiatric conditions.
- To assess the predictive power of experimental performance models for long-term schizophrenic outcomes.
Main Methods:
- Clinical observation of reactive psychoses, manic-depressive psychoses, and schizophrenic psychoses.
- Assessment of unconditional reflex activity and its relationship to psychodynamic complexes.
- Development and validation of prognostic models based on experimentally established performance impairments.
Main Results:
- Manic-depressive psychoses show marked disturbances in unconditional reflex activity, suggesting a biological basis for mood and vegetative function changes.
- Schizophrenic psychoses present with inhibited unconditional reflex responses and dissociations between reflex levels and signaling systems.
- Experimental performance-based prognostic models effectively predict long-term schizophrenic defects, comparable to clinical symptom-based models.
Conclusions:
- Unconditional reflex activity is a crucial physiological factor in understanding manic-depressive and schizophrenic psychoses.
- Schizophrenia may be understood as a functional maladaptation explained by autokinesis and schizokinesis.
- Psychophysiology and experimental psychology are vital for future diagnosis and prognosis in functional psychoses, supporting prophylactic psychiatry.
