Dr. Roach: Capgras syndrome causes woman to believe spouse is dead
The Detroit News • • health
Key Points:
- Capgras syndrome is a delusional disorder where a person believes a close family member has been replaced by an imposter, often worsening at night and frequently leading to violence against the perceived imposter.
- Approximately 70% of Capgras cases are linked to Lewy body dementia, with symptoms including the belief that someone else is living in the home, aiding diagnosis.
- Treatment involves both medications (such as donepezil and antipsychotics) and non-drug approaches, but drug treatments have limited effectiveness and require expert supervision.
- Involuntary treatment is possible if the person poses a danger to themselves or others and lacks decision-making capacity, but this requires legal processes that vary by state and should be managed by psychiatric experts.
- Families affected by Capgras syndrome are advised to consult psychiatrists specialized in psychosis and delusions to explore treatment options and support strategies.
