Lyrics:

Huntington's disease: part one of a two-part feature
In the first of this two part feature Lynne Malcolm traces one brave family's personal experience of the genetic progressive disorder known as Huntington's disease. It mostly affects adults, with symptoms usually appearing between the ages of 30 and 50. They cause cognitive difficulty and psychiatric illness as well as uncontrolled jerky movements. If one of your parents has the genetic mistake you have a fifty-fifty chance of inheriting it. It's an incurable illness which raises many complex issues in families and society.
