Minor physical anomalies in schizophrenia
1Department of Psychiatry and Medical Psychology, Higher Medical Institute, Plovdiv, Bulgaria.
Objective:
The study was conducted to evaluate the spread of the minor physical anomalies (MPAs) in patients with schizophrenia and normal subjects, and the relevance of MPAs to sex, age of onset of the disease, birth order, and season of birth.
Methods:
Forty two inpatients satisfying the DSM-IV criteria for schizophrenia and 36 normal controls were evaluated for MPAs using the Waldrop scale. Subjects with schizophreniform, schizoaffective and schizotypal personality disorders were excluded from the sample to prevent these from possible confounding of the results.
Results:
The schizophrenic patients showed significantly more anomalies than the controls. In both male and female patients, there was a higher incidence of anomalies in the region of the head. Significantly higher scores for minor physical anomalies were associated with later position in the birth order. Gender differences were without statistical significance. No relationship was found between minor physical anomalies and age of onset of the disease and birth season.
Conclusion:
The results are consistent with the theory of disturbed craniofacial development in at least one subpopulation of schizophrenic patients and indicate the origins of the disturbance in the early embryonal period. The higher incidence of anomalies in the region of head reflects the complex processes in the morphogenesis of mouth, ears and eyes.
Insights
Patients with schizophrenia exhibit more minor physical anomalies (MPAs), particularly in the head region, compared to controls. These anomalies correlate with birth order, suggesting early developmental disturbances.
Area of Science:
- Neuroscience
- Developmental Biology
- Psychiatry
Background:
- Minor physical anomalies (MPAs) are potential indicators of neurodevelopmental disturbances.
- Schizophrenia is a complex psychiatric disorder with suspected early developmental origins.
Purpose of the Study:
- To assess the prevalence of MPAs in schizophrenia patients versus controls.
- To investigate the association of MPAs with demographic and perinatal factors in schizophrenia.
Main Methods:
- Evaluation of 42 schizophrenia patients and 36 controls using the Waldrop scale for MPAs.
- Exclusion of related psychiatric disorders to ensure sample purity.
Main Results:
- Schizophrenia patients displayed significantly higher MPA scores than controls.
- Head region anomalies were more frequent in both male and female patients.
- Higher MPA scores were linked to later birth order; no significant gender, age of onset, or birth season correlations were found.
Conclusions:
- Findings support theories of disturbed craniofacial development in schizophrenia, originating in early embryogenesis.
- Increased head anomalies reflect complex morphogenesis of facial features like mouth, ears, and eyes.
