All these conditions have specific and visible gut symptoms, chemical exposure and nutritional reasons. Based on where it is affected this group of diseases demonstrate different conditions and symptoms. Here are the current observations based on research and clinical findings.
- Asperger Syndrome - This is on the milder end of the Autism Spectrum. This is often with a child's obsessive interest in a single object or topic to the exclusion of any other. Because of their narrow interest and poor social skills, children with this disorder are often isolated and have trouble making normal conversation.
- Childhood Disintegrative disorder. It's relatively rare and hence, very few children meet the criteria for this particular disorder. The loss of vocabulary is more dramatic in this condition than in classical autism. This disorder is also accompanied by loss of bowel and bladder control and, in many cases, seizures and a low IQ. It described children who develop normally and then quickly lose many social, language, and mental skills, usually between ages 2 and 4. Often, these children also developed a seizure disorder.
- Pervasive developmental disorder, not otherwise specified (PDD-NOS) - Autism is the most characteristic and best-seen in this group of disorders. There is a delay in the development of social and communication skills. Children with this disorder vary widely in abilities, intelligence, and behaviours. Early intervention, gut upgrade, detoxification, and natural lifestyle are the answers. This diagnosis included most children whose autism was more severe than Asperger's syndrome, but not as severe as autistic disorder.
- Rett Syndrome - Usually affects females. Rett syndrome is a PDD. Its symptoms begin after a period of normal development that lasts between 6 and 18 months, after which the child's mental and social development regresses. Scientists have discovered that a mutation in the sequence of a single gene can cause Rett syndrome. This discovery may also lead to methods of screening for the disorder.
- Autistic disorder. This older term is further along the autism spectrum than Asperger’s and PDD-NOS. It includes the same types of symptoms, but at a more intense level.
