Refer a patient with suspected Huntington's disease to a specialist (such as a neurologist with expertise in movement disorders) promptly for further evaluation and management. This referral should be made as soon as Huntington's disease is suspected based on clinical features, to confirm the diagnosis, exclude alternative diagnoses, and initiate appropriate multidisciplinary care.
Although the provided guidelines do not explicitly mention Huntington's disease, the general principle for suspected progressive neurological conditions with movement disorder features is to arrange specialist referral without delay, similar to the approach for Parkinson's disease and other movement disorders.
Early specialist involvement allows for accurate diagnosis, genetic counselling, symptom management, and support for the patient and family.
