HUNTINGTON'S DISEASE

WHAT IS HD?

Huntington's disease is a genetic disorder resulting in the gradual breakdown of nerve cells in the brain. 

HOW COMMON IS HD?

Huntington's disease is considered extremely rare, with approximately 30,000 cases in the United States.

HOW IS HD TRANSMITTED?

Huntington's disease is an autosomal dominant disorder, meaning one copy of the defective gene is enough to inherit the disorder. Huntington's is passed on genetically and every child of a parent with HD has a 50% chance of inheriting the gene. 

WHAT ARE THE SYMPTOMS OF HD?

Symptoms of Huntington's disease usually appear between the ages of 30 - 50 in an affected individual and worsen over a 10-25 year period. Symptoms include personality changes, mood swings and depression, forgetfulness/impaired judgement, difficulty with control over physical movement, slurred speech, difficulty swallowing and significant weight loss.

TREATING HUNTINGTON'S DISEASE

There is currently no cure for Huntington's - treatments to date involve managing symptoms through drugs, physical and speech therapy. 

DIAGNOSING HUNTINGTON'S DISEASE

A genetic test to determine inheritance of Huntington's was developed in the early 1990's and is done using a blood sample.
