Huntington's disease-like syndrome is a group of inherited disorders that are similar in many ways to Huntington's disease. The disorders are characterized by a triad of symptoms: movement abnormalities, cognitive decline, and psychiatric disturbances.

Symptoms

The symptoms of Huntington's disease-like syndrome are similar to those of Huntington's disease. They include:

• Chorea: Uncontrolled, irregular, jerky movements
• Dystonia: Involuntary muscle contractions that cause slow repetitive movements or abnormal postures
• Parkinsonism: Symptoms similar to those of Parkinson's disease, such as bradykinesia (slowness of movement), rigidity (stiffness), and tremor
• Cognitive decline: Problems with memory, judgment, and thinking
• Psychiatric disturbances: Depression, anxiety, and changes in personality or behavior

Causes

Huntington's disease-like syndrome is caused by mutations in several different genes. The most common are the PRNP gene (Huntington's disease-like 1), the JPH3 gene (Huntington's disease-like 2), the TBP gene (Huntington's disease-like 4), and the SCA17 gene (Huntington's disease-like 4).

Diagnosis

Diagnosis of Huntington's disease-like syndrome is based on the symptoms, family history, and genetic testing.

Treatment

There is no cure for Huntington's disease-like syndrome. Treatment is focused on managing the symptoms and improving quality of life. This may include medications to control movement problems, therapy to manage psychiatric symptoms, and supportive care.
