Children with autism often shown repetitive behaviours, ranging from repeated movements to compulsively collecting or arranging objects and desiring that daily routines are always done in the exact same way. Repetitive behaviour is often considered one of the three core features of autistic disorders (alongside difficulties in social interaction, and difficulties in communication).
SSRI antidepressants are often used to try to treat repetitive behaviours. Unfortunately, they don't work, at least according to a new study - Lack of Efficacy of Citalopram in Children With Autism Spectrum Disorders and High Levels of Repetitive Behavior.
