1. Huntington’s Disease

2.  A rare and incurable neurological disease that eats away at the nerves and the brain, causing total mental deterioration over a period of 12-15 years.  It affects a person ability to think, talk and move

3.  The Huntington gene codes for a protein that delivers molecules to cells.  The mutation causes the DNA sequence “CAG” to be repeated too many times and causes brain cells to accumulate clumps of protein that become toxic, resulting in cell death.  Some patients loose more that 25% of their brain cells before they die.

4. The brain Huntington’s Normal

5.  HD is autosomal dominant- that means everyone that inherits the faulty gene will eventually get the disease.  A parent with the HD mutation has a 50% chance of passing on the disease to their children.

7.  During pregnancy- taking a sample of fluid from around the baby (amniocentesis)  After birth- genetic test for gene mutation  THE TEST CANNOT TELL AT WHAT AGE A PERSON WILL BEGIN TO GET SICK.

8. Usually begin between the ages of 30 and 50 but may appear earlier or later in life Poor memory Depression and/or mood swings Lack of coordination Twitching or uncontrolled movements Difficulty in walking, speaking and /or swallowing In the late stages of the disease, a person will need help doing even simple tasks, such as getting dressed.

9.  While drugs can alleviate some of the symptoms of Huntington's disease, it is always fatal. Suicide rates are high. Within five years of developing symptoms, most people quit work.  Eventually, people with Huntington's disease die of illnesses like pneumonia, caused by food or liquids that slip into the lungs.

15.  He has chosen not to be tested  His children may feel differently
