The single condition known as 'autism' is quickly becoming outdated, and is now understood to be an umbrella term for a variety of genetic conditions. This can be confusing for parents of children who have been diagnosed as having an 'autism spectrum disorder'. ''A-Z of Genetic Factors in Autism'' provides parents with a complete overview of the genetic disorders most commonly associated with autism, including those linked to immune dysfunction, gastrointestinal disturbances, seizures, fits, and epilepsy. Kenneth Aitken demystifies the umbrella term 'autism' by alphabetically listing these conditions along with information about how common they are, their causes, signs, and symptoms, and appropriate methods of treatment and management. Information on support groups and sources of further information are also included to help parents obtain any additional support they need. This is a must-have book for any parent or carer who feels confused by their child's diagnosis, or who seeks a better understanding of the many genetic conditions linked to autism.
