Lecture by Mark Hutten, M.A. - Part 1 discusses obsessive thinking among individuals with Asperger's and High-Functioning Autism:
More about intrusive thoughts in the autistic mind:
Research has shown that obsessive thinking is associated with a variety of negative consequences, including depression, anxiety, binge-drinking and binge-eating. For some people, drinking or binge-eating becomes a way to cope with life and drown out their obsessive thinking.
When people obsess while they are in depressed mood, they remember more negative things that happened to them in the past, they interpret situations in their current lives more negatively, and they are more hopeless about the future. Obsessive thinking also becomes the fast track to feeling helpless. Specifically, it paralyzes your problem-solving skills. You become so preoccupied with the problem that you’re unable to push past the cycle of negative thoughts. It can even turn people away. When people obsess for an extended time, their family members and friends become frustrated and may pull away their support.
