What People Often Get Wrong About Huntington’s Disease
Huntington’s disease is one of those conditions many people have heard of, but few truly understand. Too often, it gets reduced to “a movement disorder” or confused with other neurological diseases. In reality, Huntington’s affects movement, thinking, mood, behavior, and families across generations.
One common misconception is that Huntington’s disease only causes involuntary movements. While uncontrolled movements can be part of it, the disease can also bring changes in memory, decision-making, depression, anxiety, irritability, and personality. For many families, the emotional and cognitive symptoms can be just as difficult as the physical ones.
Another misconception is that people with Huntington’s are “acting out” or choosing their behavior. They are not. Huntington’s causes progressive changes in the brain, which can affect impulse control, communication, emotions, and judgment. Compassion matters because what looks like stubbornness, anger, or withdrawal may actually be part of the disease.
Some people also think Huntington’s only affects older adults. Symptoms most often appear between ages 30 and 50, but they can begin earlier or later, and juvenile Huntington’s can affect children and teens.
There is also confusion about heredity. Huntington’s is genetic, and each child of a parent with Huntington’s has a 50% chance of inheriting the gene expansion that causes the disease. That means Huntington’s does not affect just one person. It affects entire families who may be living with symptoms, caregiving responsibilities, genetic testing decisions, grief, fear, and uncertainty.
And perhaps the biggest misconception is that a diagnosis means a person’s life is over. Huntington’s is serious and currently has no cure, but people with Huntington’s still deserve dignity, connection, support, good care, and full recognition of their humanity. A diagnosis does not erase who someone is.
Awareness matters. The more we understand Huntington’s disease, the better we can support the people and families living with it.
If you know someone affected by Huntington’s, listen without judgment. Learn before assuming. Offer help without waiting to be asked. And most of all, remember that behind every diagnosis is a person, a family, and a story that deserves compassion.
