Imagine losing control of your body, thoughts, and emotions—slowly and progressively. That’s the reality for people living with Huntington’s Disease, a rare but serious genetic disorder that affects both the brain and body. Though symptoms can begin subtly, recognizing the signs early is essential for planning treatment and support.
If you’ve noticed mood swings, clumsy movements, or changes in thinking and behavior, you may wonder: could it be Huntington’s Disease? This article breaks down what you need to know, from how it starts to what testing looks like, so you can feel more informed—whether you’re seeking answers for yourself or someone you love.

What Is Huntington’s Disease?
Huntington’s Disease is a rare, inherited neurological condition that gradually damages certain brain cells. It leads to progressive problems with movement, thinking (cognition), and emotions. The condition is caused by a defect in a single gene—specifically, a mutation in the HTT gene on chromosome 4. This defect leads to the production of a toxic protein that slowly kills neurons in key areas of the brain.
Unlike many brain disorders, Huntington’s is genetic. If one parent carries the faulty gene, there’s a 50% chance their child will inherit it. The condition affects both men and women and typically shows up in adulthood, often between ages 30 and 50. However, a rarer form, known as juvenile Huntington’s disease, can begin during childhood or adolescence.
While there is no cure, treatment can improve quality of life and help manage symptoms. Research is advancing, with several promising gene-silencing therapies currently in development or early clinical trials.

Signs and Symptoms to Watch For
Symptoms of Huntington’s Disease can vary widely, even among family members who share the gene. Early on, changes may be mistaken for depression, clumsiness, or simple forgetfulness. However, the disease progresses in predictable stages, affecting physical, cognitive, and emotional health.
Motor Symptoms
Most people first notice changes in movement. These may include:
- Involuntary jerking or twitching (chorea)
- Poor coordination or balance
- Trouble with speech or swallowing
- Slowed movements or muscle rigidity in later stages
Some individuals appear fidgety, clumsy, or unsteady years before receiving a formal diagnosis.
Cognitive Decline
Problems with attention, memory, and planning also arise. Many experience:
- Difficulty organizing tasks
- Slower processing of information
- Poor impulse control or judgment
- Trouble learning new things
These changes can impact job performance, relationships, and decision-making. For caregivers, it’s often the cognitive and emotional symptoms—not the movement issues—that cause the most stress.
Emotional and Behavioral Changes
Mood disorders are common and may even appear before motor symptoms. These can include:
- Depression or apathy
- Irritability and anger
- Anxiety or obsessive behavior
- Social withdrawal
Some patients struggle to recognize their own symptoms, a condition called anosognosia, which can make early intervention more difficult.
How It’s Diagnosed and Who’s at Risk
Diagnosing Huntington’s Disease involves a combination of family history, clinical evaluation, neurological exams, and genetic testing. If someone has a parent with Huntington’s, a genetic test can confirm whether they carry the mutation—even before symptoms appear.
However, predictive testing is a personal decision. Genetic counseling is strongly recommended to help individuals weigh the emotional and ethical implications of knowing their risk.
Doctors may also use:
- MRI or CT scans to assess brain atrophy
- Neuropsychological testing to evaluate memory and reasoning
- Blood tests to rule out other causes of symptoms
The decision to pursue testing depends on many factors, including age, family planning, and symptom progression. If you’re considering testing, speak with a medical geneticist or a professional through Healthcare.pro to find a specialist near you.
What You Can Do Next
If you or a loved one shows symptoms of Huntington’s Disease, early action is crucial. Although there is no cure, a care team can help manage symptoms through medications, therapy, and planning. Approved drugs like tetrabenazine (Xenazine) and deutetrabenazine (Austedo) help reduce chorea. Antidepressants and antipsychotics are sometimes used for mood and behavior.
In addition, occupational therapy, physical therapy, and speech therapy can all extend independence and improve daily function.
Consider the following steps:
- Document symptoms and changes in behavior
- Schedule a neurology consult for a comprehensive evaluation
- Engage a support network through forums, counselors, and community programs
- Plan ahead by discussing legal and financial matters early
Importantly, many people with Huntington’s live fulfilling lives for years after diagnosis. Advances in research—including gene-editing and RNA-targeting therapies—offer real hope for future treatments.

FAQs
What is Huntington’s Disease?
Huntington’s Disease is a genetic brain disorder that causes progressive decline in movement, thinking, and emotional control due to a mutation in the HTT gene.
How do I know if I have Huntington’s Disease?
Symptoms like jerky movements, memory issues, and mood swings may signal the disease. A genetic test is required for a definitive diagnosis.
Is Huntington’s Disease curable?
Currently, there is no cure. However, treatments can manage symptoms, and promising research is underway, including gene-targeting therapies.
Can children get Huntington’s Disease?
Yes, though it’s rare. Juvenile Huntington’s Disease can affect those under 20 and typically progresses more rapidly.
Should I get tested if Huntington’s runs in my family?
Genetic testing is a personal choice. If you’re at risk, speak with a genetic counselor to explore your options.
