37
Catatonic Type
involves a disturbance in movement. Some might stop moving (catatonic stupor) or experience radically increased movement (catatonic excitement). Also, these individuals might assume odd positions, continuously repeat what others are saying (echolalia) or imitate another person’s movement (echopraxia).
38

Brain Structure Differences
-Enlarged ventricles, ↑ brain tissue loss over time
Diathesis-stress Model
- Disturbed Home Environment Example:
- Sz bio mom + disturbed adoptive home = high risk of Sz
- Sz bio mom + healthy adoptive home = moderate risk
- No Sz bio mom + disturbed adoptive home = low risk
Prenatal Environment
Malnutrition, viral infection, birth complications : ↑ risk
