Current research on the causes of autism and related pervasive developmental disorders is uncovering some possible genetic predisposition to the syndromes. There seems to be a connection with other psychological conditions including depression, bipolar disorder, schizophrenia, and PDD syndromes.
Environmental factors affect pervasive developmental disorders?
Some research is investigating the possibility of environmental factors in the development of conditions, such as Asperger syndrome.
- Heavy metals are being investigated as possible contributors to autism.
- MMR vaccines that contained a mercury-based preservative are to blame.
- Environmental factors also include pollutants.
Does diet play a part in the autism spectrum of disorders?
- Speculations are that Asperger syndrome is caused by a reaction to certain foods.
- This food allergy results in the symptoms of autism and related pervasive developmental disorders - main culprits are thought to be casein and gluten.
