What are the best treatments for Benign Hereditary Chorea BHC?

TL;DR: There is currently no curative treatment for Benign Hereditary Chorea (BHC), so management focuses on symptom relief through multidisciplinary care tailored to the individual. Because symptoms of Benign Hereditary Chorea often stabilize or improve slightly with age, treatment is primarily supportive and aimed at improving quality of life.

What are the first-line treatments for Benign Hereditary Chorea?

Treatment for Benign Hereditary Chorea is highly personalized because the severity of choreic movements varies significantly between patients. While many individuals with Benign Hereditary Chorea require no medication at all, those with significant functional impairment may be prescribed dopamine-depleting agents or dopamine receptor antagonists to manage involuntary movements. It is critical that any pharmacological intervention be managed by a movement disorder specialist, as the goal is to balance symptom control with the avoidance of side effects.

What non-pharmacological therapies are used for Benign Hereditary Chorea?

Non-pharmacological approaches are the cornerstone of managing Benign Hereditary Chorea. These therapies focus on maintaining physical function and adapting to daily challenges:

• Physical Therapy: Essential for improving balance, gait, and coordination to prevent falls.


• Occupational Therapy: Focuses on adaptive strategies for daily tasks, such as writing or using utensils, to maintain independence.


• Speech Therapy: Recommended if choreic movements affect the muscles involved in swallowing or speech articulation.

Which specialists should be on the care team?

Because Benign Hereditary Chorea is a rare, lifelong condition, a coordinated team approach is vital. Your care team should ideally include a neurologist specializing in movement disorders, a clinical geneticist to discuss inheritance patterns, and physical or occupational therapists. Two members of the DiseaseMaps community have already begun connecting to share their experiences with managing these multidisciplinary needs.

Are there emerging treatments for Benign Hereditary Chorea?

Clinical research into Benign Hereditary Chorea remains limited due to its rarity. Currently, there are no specific curative clinical trials for this condition. Most research focuses on the broader spectrum of chorea-related disorders, with clinicians applying evidence-based strategies from other hyperkinetic movement disorders to support patients with Benign Hereditary Chorea.
