[Huntington's disease in psychiatric practice]

Area of Science:

• Neurology
• Psychiatry
• Genetics

Background:

• Huntington's disease (HD), also known as Huntington's chorea, is a rare genetic neurodegenerative disorder.
• While chorea is a hallmark motor symptom, psychiatric and cognitive manifestations are also significant contributors to disability and social isolation in HD patients.
• These non-motor symptoms can precede the onset of motor deficits, impacting diagnosis and management.

Purpose of the Study:

• To review the most common comorbid mental disorders in Huntington's disease.
• To describe the characteristics and clinical course of these psychiatric comorbidities.
• To highlight the importance of recognizing non-motor symptoms in the early stages of HD.

Main Methods:

• Literature review of psychiatric comorbidities in Huntington's disease.
• Analysis of own clinical observations and patient data.
• Synthesis of information on the prevalence, phenomenology, and progression of mental disorders in HD.

Main Results:

• Psychiatric symptoms, including depression, anxiety, and psychosis, are highly prevalent in Huntington's disease.
• Cognitive impairments, such as executive dysfunction and memory deficits, frequently co-occur with psychiatric conditions.
• The onset and severity of psychiatric and cognitive symptoms vary among individuals but significantly contribute to overall disease burden.

Conclusions:

• Huntington's disease presents a complex interplay of motor, psychiatric, and cognitive symptoms.
• Comprehensive assessment and management of mental health are crucial for improving the quality of life for individuals with Huntington's disease.
• Early identification of psychiatric and cognitive manifestations is essential for timely intervention and patient support.
