Catatonia in autistic spectrum disorders.
Summary
Catatonia can be a severe complication of autistic spectrum disorders (ASD) in adolescents and adults. Early signs like impaired language and social passivity may predict this later exacerbation.
Area of Science:
- Neuroscience
- Developmental Psychology
- Psychiatry
Background:
- Autistic spectrum disorders (ASD) can present with clinical features overlapping with catatonia.
- Catatonia represents a severe deterioration in skills and behavior observed in some individuals with ASD.
Purpose of the Study:
- To investigate the exacerbation of catatonic features in individuals with autistic spectrum disorders during adolescence and early adulthood.
- To identify potential predictors and characteristics associated with severe catatonia in ASD.
Main Methods:
- A semi-structured interview was conducted with caregivers of 506 individuals referred to an ASD specialist clinic.
- Individuals with severe catatonic features were compared to a control group of similar age without such deterioration.
Main Results:
- Approximately 17% of referrals aged 15 and over exhibited severe catatonic features.
- Pre-existing impaired language and social passivity were significantly more common in individuals who developed severe catatonia.
Conclusions:
- Catatonia is identified as a significant later-life complication of autistic spectrum disorders, increasing caregiving challenges.
- Further research is crucial to understand the underlying causes, neuropathology, and early indicators of vulnerability for catatonia in ASD.
