Huntington’s disease is a genetic disorder which can be fatal in nature. It is caused by a defect in a single gene which causes mutant proteins. It also causes progressive breakdown of nerve cells in the brain and deteriorates a person’s physical and mental abilities.
It is known as quintessential family disease because every parent who has Huntington disease has 50% chances that his child will be affected with that disease by carrying the defective gene.
It affects the whole brain.
Symptoms usually appear in the age between 30 to 50.
• Pneumonia, heart failure
• Personality changes, mood swings
• Forgetfulness and impaired judgement
• Slurred speech
• Weight loss
• Difficulty in swallowing.
