Establishing a diagnosis for ataxia telangiectasia is most difficult in very young children, primarily because the full-blown syndrome is not yet apparent.
Genetic counseling is also of benefit to prospective parents with a family history of ataxia-telangiectasia.
Any family touched by ataxia telangiectasia is forever affected.
A-T support groups have been organized by all major A-T organizations, such as the Ataxia Telangiectasia Children's Project, the National Ataxia Foundation (NAF), and the Ataxia Telangiectasia Medical Research Foundation.
