Huntington's Disease Awareness Month – May 2024

Huntington Disease Awareness Month is celebrated in May every year. Huntington’s disease (H.D.) is a genetic disorder that has no cure. It causes a progressive breakdown of nerve cells in the brain leading to the deterioration of a person’s physical, mental, and emotional abilities. Every month is an important time to raise awareness about Huntington’s disease but each May, there is a focus and concentrated effort to educate people, break down stigma, support and bring hope to people with H.D. and their families. During May, buildings, monuments, and statues are usually lit up in blue and purple, blue to raise awareness of Huntington’s disease, and purple for juvenile Huntington’s. Patients, caregivers, families, and friends nationwide are organizing fundraisers, planting virtual flowers, lighting landmarks blue and purple, taking hikes, flooding social media, and sharing stories about H.D. It is all intended to heighten awareness among the general public and draw the attention of policymakers, public authorities, scientists, health professionals, and industry representatives.

History of Huntington's Disease Awareness Month

Huntington Disease Awareness Month in May is sponsored by the Huntington’s Disease Society of America. It is a nonprofit organization and the world’s leader in improving the lives of people living with H.D. Through community services, education, advocacy, and research, they provide help and bring hope to people with H.D. and their families.

Initiated by the Huntington’s Society of Canada, over the years, May has become an international Huntington’s Disease Awareness Month. Huntington’s disease is a rare, progressive, inherited brain disorder that causes uncontrolled movements like jerking or twitching, emotional problems, and loss of thinking ability (cognition). The disease causes brain cells called neurons to die in various areas of the brain, including those that help to control voluntary and intentional movement. The disease is named after George Huntington, who described it among residents of East Hampton, Long Island in 1872. In 1993, a collaborative group of investigators discovered the gene that causes H.D. With this discovery, it is now possible to diagnose H.D. with blood or tissue samples.

While some people are born with the mutated gene for H.D., in most cases, they will not develop the symptoms until later in life. Therefore, someone can be without H.D. or pre-symptomatic for several years. The initial signs of this disorder may be subtle. It is characterized by a movement disorder, dementia and psychiatric disturbances, personality changes, weight loss, difficulty swallowing and hard-to-understand speech are additional characteristics of H.D.

One of the initial ways to raise awareness for Huntington’s Disease was the #LightItUp4HD Campaign, where landmarks and monuments across Canada were lit in blue and purple. Blue for H.D. and purple for Juvenile H.D. Huntington Disease Awareness Month is a time to raise awareness of Huntington’s with the wider public.

  2. It is a time for fundraising

    The H.D.A. During the #HDHike challenge encourages supporters to participate in fundraising for people living with H.D. by organizing their own five-mile walk or individually taking at least 8,000 steps daily through May. The aim is for each participant to raise £100.
