I am usually bombarded with questions from parents/caregivers and other people working with children suffering from Autism to get answers to their specific queries and problems. Many a times parents have told me that they felt completely lost when they discovered their child has Autism and few years back there was very little awareness and orientation about the problem. They kept wondering what causes Autism and why has this happened to their children
One of the most frequently asked question is:
What causes Autism?
The answer to this is debatable and there is no word or theory supporting it. Many theories have been put forward, some have good scientific backing others have weak scientific backing.
Some of the known causes are genetic complications (there is no one single gene involved and the answer to this is complex with many genes having a role to play, complications like maternal bleeding in the first trimester/diabetes/increased maternal/paternal age, chromosomal abnormalities, immunological incompatibility, neonatal complications like respiratory distress syndrome and neonatal anemia, neuroanatomical factors (temporal lobe damage usually results in restlessness, impaired social behavior, repetitive motor behavior etc.) and in some cases biochemical factors (high plasma serotonin concentration, high concentrations of homovaillic acid). There could also be certain environmental factors at play like metal poisoning, infectious diseases, parental smoking, alcohol and illicit drug use.
It can also be associated with neurological conditions like congential rubella, phenylketonuria, tuberous sclerosis, rett’s disorder and genetic disorders like fragile X syndrome.
In many cases children suffering from Autism also have mental retardation (severity varies), seizure disorders, obsessive compulsive disorders etc.
These are only some of the possible causes and theories put forward in the course of time by various researchers, there are many more hypotheses put forward but have yet to be proved and have scientific backing.
I personally feel that it is the responsibility of every mental health worker to educate parents about possible causes, characteristics, scope of improvement and available treatment with advantages and disadvantages. Parental counseling programs, programs based on orientation to autism are a must and should be religiously carried out from time to time. The pattern followed by most professionals is quick diagnosis and directing a set of treatment but what they often forget is parental counseling and education about the problem. Unless this is achieved percentage of denial amongst parents will be high and weaker the scope of improvement.
The present article is to help parents/caregivers understand some of the causes related to autism and work towards effective treatment. :-)
