Huntington’s Disease: Nursing Care, Symptoms, and NCLEX Review

Huntington’s disease is a rare, inherited neurological disorder that affects the brain’s nerve cells, causing progressive loss of physical and mental abilities. For any nurse, understanding this condition is essential—especially for registered nurses (RN nurses) preparing for the NCLEX or caring for patients with neurodegenerative diseases. This guide simplifies the key concepts, nursing interventions, and patient education points every nursing student should know.

🧠 What Is Huntington’s Disease?

Huntington’s disease (HD) is a genetic disorder that leads to the gradual breakdown of neurons in certain areas of the brain, particularly the basal ganglia and cerebral cortex. This degeneration affects a person’s movement, cognition, and behavior over time.

It is caused by a mutation in the HTT gene, which produces an abnormal form of the huntingtin protein. The defective protein accumulates in the brain, leading to nerve cell damage and loss of motor control.

🧬 Causes and Risk Factors

• Genetic inheritance (autosomal dominant): Only one copy of the defective gene is needed for a person to develop the disease.
• Family history: If one parent has the gene mutation, each child has a 50% chance of inheriting it.
• No cure or prevention: While genetic testing can identify carriers, there’s currently no known cure for Huntington’s disease.

⚠️ Early Signs and Symptoms

The symptoms often begin between ages 30 and 50, but juvenile cases can occur. Early manifestations can vary, but common signs include:

Motor Symptoms

• Involuntary jerking movements (chorea)
• Muscle problems, such as rigidity or dystonia
• Slow or abnormal eye movements
• Difficulty with speech or swallowing
• Impaired coordination and balance

Cognitive Symptoms

• Difficulty focusing or planning
• Memory problems
• Reduced ability to learn new information
• Poor decision-making

Psychiatric and Behavioral Symptoms

• Depression and anxiety
• Irritability and aggression
• Mood swings
• Social withdrawal

🩺 Diagnosis and Testing

Diagnosis involves a combination of:

• Neurological examination to assess motor and cognitive function
• Genetic testing to confirm the HTT gene mutation
• Brain imaging (MRI/CT) to detect structural changes in brain tissue

As a registered nurse, you should understand how these diagnostic tools help confirm the disease and guide care planning.

💊 Treatment and Management

Although there’s no cure, treatment focuses on managing symptoms and improving quality of life.

Medications

• Tetrabenazine or Deutetrabenazine: Reduce involuntary movements
• Antidepressants (SSRIs): Manage mood changes
• Antipsychotics: Control aggression or severe behavioral issues

Supportive Therapies

• Physical therapy: Maintains mobility and balance
• Occupational therapy: Assists with daily living activities
• Speech therapy: Helps with communication and swallowing
• Nutritional support: Ensures adequate calorie intake, as weight loss is common

👩‍⚕️ Nursing Care Plan for Huntington’s Disease

Every nurse caring for a patient with Huntington’s disease should provide holistic care that addresses physical, emotional, and social needs.

Nursing Diagnoses

1. Impaired physical mobility related to muscle incoordination
2. Risk for aspiration related to dysphagia
3. Impaired communication related to speech difficulties
4. Risk for injury due to choreic movements
5. Disturbed thought processes related to brain degeneration

Nursing Interventions

• Encourage safe ambulation and use of assistive devices.
• Implement aspiration precautions: elevate the head of the bed and monitor swallowing.
• Provide a calm environment to minimize stress.
• Educate caregivers about disease progression and home safety.
• Promote emotional support for both the patient and family.

Patient and Family Education

• Teach about genetic counseling for family members.
• Emphasize the importance of regular follow-ups and multidisciplinary care.
• Encourage support groups to reduce caregiver burnout.

🧾 Huntington’s Disease and the NCLEX

For NCLEX preparation, focus on:

• Recognizing key symptoms like chorea and cognitive decline
• Prioritizing safety and injury prevention
• Implementing nutrition and aspiration precautions
• Providing emotional support and patient education
• Understanding genetic transmission patterns

These points frequently appear in nursing bundles that cover neurological disorders.

💡 Tips for RN Nurses and Nursing Students

• Review the neurological system section in your nursing bundle before exams.
• Use mnemonics to remember chorea and cognitive symptoms.
• Practice NCLEX-style questions focusing on patient safety and family teaching.
• Remember: Compassion and patience are key to caring for these patients.

💬 Final Thoughts

For every nurse and RN nurse, understanding Huntington’s disease means more than just memorizing facts—it’s about compassionate care. Patients with this condition need nurses who can recognize symptoms early, manage complications, and support families through challenging times.
