The way they diagnose Huntington’s Disease is by testing close members of your family for a history of Huntington’s disease or the Huntington’s gene, by running genetic testing to locate the Huntington’s gene, as well as assessments of neurological, emotional and physical symptoms. The gene of Huntington’s disease can be passed on from biological parents with Huntington’s or parents carrying the Huntington’s gene having a child, that child then has a fifty percent chance of getting the gene from their parents and developing the disease.

Patients who can possibly have the gene can take a gene test to see if they have the Huntington’s gene. To have the test for Huntington’s you are required to be at least 18 years of age. Deciding if you would like to have the test to identify the gene or not is a difficult decision that requires a lot of thought. A lot of organizations offer counselling to help people who have Huntington’s disease and their family, carers, and friends to cope with the genetic result.
