When aggression reaches the point where you have a concern about harm to yourself, to the affected person or to others involved in the care of a person with Huntington's disease, you must get professional help as soon as possible. Behavioral modification techniques can work, but there are times when medications may be clearly needed as an adjunct to other techniques. Health care providers with expertise in Huntington's disease can be most helpful in this area.
