Huntington’s disease (HD) is a rare, inherited neurodegenerative disorder that primarily affects the brain
1
. It’s caused by a genetic mutation in the huntingtin gene (HTT), which leads to the gradual breakdown and death of nerve cells in certain parts of the brain
2
. This disease typically manifests in middle age, usually between 30 and 50 years old, but it can also appear earlier or later in life
1
.
The symptoms of Huntington’s disease are diverse and can be categorized into three main areas: movement disorders, cognitive impairments, and psychiatric conditions
3
. Movement disorders are often the most noticeable and include involuntary jerking or writhing movements known as chorea
3
. These movements can affect all muscles, including those in the arms, legs, face, and tongue
3
. As the disease progresses, individuals may experience muscle rigidity, slow or unusual eye movements, trouble walking, and difficulty with speech or swallowing
3
.
Cognitive impairments in Huntington’s disease can include difficulties with organizing, prioritizing, and focusing on tasks
3
. People with HD may also exhibit a lack of impulse control, leading to outbursts, impulsive actions, and even sexual promiscuity
3
. Additionally, they may struggle with learning new information and experience a decline in their ability to process thoughts
3
.
Psychiatric conditions are also common in Huntington’s disease, with depression being the most prevalent
3
. This isn’t simply a reaction to the diagnosis but rather a result of changes in brain function and structure
3
. Other psychiatric symptoms can include apathy, irritability, and a lack of awareness of one’s own behaviors and abilities
3
.
Unfortunately, there is no cure for Huntington’s disease, and treatments are primarily aimed at managing symptoms
3
. Medications can help control movement disorders and psychiatric symptoms, but they cannot halt the progression of the disease
3
. Supportive care, including physical therapy, occupational therapy, and counseling, can also be beneficial in improving the quality of life for individuals with HD.
Huntington’s disease is inherited in an autosomal dominant manner, meaning that a child has a 50% chance of inheriting the mutated gene if one parent carries it
1
. Genetic testing can confirm the presence of the mutation, and predictive testing can help individuals make informed decisions about their future

Huntington’s disease is a challenging condition, but ongoing research and advancements in medical science offer hope for better treatments and, eventually, a cure. If you or someone you know is affected by HD, it’s important to seek support from healthcare professionals and organizations dedicated to helping those with the disease.
