I am the mother of four young children. My oldest is a magnificently quirky, confident, brilliant 8-year-old boy, named Linus, who just happens to have Asperger's Syndrome.
Asperger's Syndrome is a form of high functioning autism, characterized by: difficulties with reciprocal social interactions (ie. carrying on a two-sided conversation); impairments in language skills (ie. forming sentences or questions correctly); narrow range of interests and an insistence on set routines; motor clumsiness; cognitive issues (ie. difficulties with problem solving, organizations, carrying out requests) and sensory sensitivities.
Most autistic children require many different medicines and treatments such as Speech Therapy, Occupational Therapy, Social Skills Training, Feeding Therapies, etc. For most, these therapies are vital, even through teen years, to help grow an individual capable of living as independently as possible. United Healthcare has a policy that stops medical coverage, relating to autism (including these therapies) at age 9.
Autism does not magically disappear at age 9, but United Healthcare and other insurance companies like it, believe that medical coverage for it should.
