[Psychiatric symptoms of Huntington's disease]

Area of Science:

• Neurology
• Genetics
• Psychiatry

Background:

• Huntington's disease (HD) is an autosomal dominant inherited neurodegenerative disorder.
• It manifests with a triad of motor, cognitive, and psychiatric symptoms.
• Psychiatric symptoms often precede motor deficits and significantly impact quality of life.

Purpose of the Study:

• To provide a comprehensive overview of the psychiatric manifestations in Huntington's disease.
• To discuss diagnostic approaches for HD-related psychiatric symptoms.
• To review current pharmacological and non-pharmacological treatment strategies.

Main Methods:

• Literature review of existing studies and clinical guidelines.
• Synthesis of information on diagnostic criteria and genetic testing for HD.
• Analysis of established treatment modalities for psychiatric symptoms in HD.

Main Results:

• Psychiatric symptoms in HD are diverse, including apathy, depression, anxiety, OCD, psychosis, and aggression.
• Diagnosis is confirmed by genetic testing for expanded CAG repeats in the Huntingtin gene.
• Current treatments focus on symptom management, as disease-modifying therapies are under investigation.

Conclusions:

• Psychiatric symptoms are a core feature of Huntington's disease, requiring careful management.
• Established clinical practice relies on expert opinion and experience from treating similar symptoms in other conditions.
• Further research into disease-modifying treatments for HD is crucial.
