What are the best treatments for Hereditary Neuropathy With Liability To Pressure Palsies HNPP?

There is currently no cure for Hereditary Neuropathy with Liability to Pressure Palsies (HNPP), so treatment focuses on managing symptoms, preventing nerve injury, and maintaining functional independence. Management is primarily conservative and multidisciplinary, centered on avoiding nerve compression and providing physical and occupational therapy to support daily activities.

What are the primary management strategies for HNPP?

Because the nerves in Hereditary Neuropathy with Liability to Pressure Palsies (HNPP) are hypersensitive to compression, the most effective "treatment" is prevention. Patients are advised to avoid prolonged limb crossing, leaning on elbows, or repetitive tasks that put pressure on vulnerable nerves. When episodes of weakness or sensory loss occur, they are typically managed with supportive care, as most palsies resolve spontaneously over weeks or months.

What non-pharmacological therapies are used?

Physical and occupational therapy are cornerstones of care for those living with Hereditary Neuropathy with Liability to Pressure Palsies (HNPP). These interventions help maintain muscle strength, prevent contractures, and provide adaptive equipment for daily living. Useful tools include:

• Custom orthotics: Such as ankle-foot orthoses (AFOs) to assist with foot drop.


• Ergonomic adjustments: Using specialized cushions or workspace modifications to reduce nerve pressure.


• Splinting: Protecting vulnerable nerves during sleep or periods of high activity.

Which specialists should be on the care team?

Managing Hereditary Neuropathy with Liability to Pressure Palsies (HNPP) requires a multidisciplinary team. Your care team should ideally include a neurologist (specializing in neuromuscular disorders), a physical therapist, an occupational therapist, and a clinical geneticist to provide counseling for family members. Surgical intervention is rarely indicated and is generally avoided, as patients with Hereditary Neuropathy with Liability to Pressure Palsies (HNPP) may have poor outcomes from nerve decompression surgery.

Are there emerging treatments or clinical trials?

Currently, there are no specific pharmacological treatments that reverse the underlying genetic defect of Hereditary Neuropathy with Liability to Pressure Palsies (HNPP), which is typically a deletion of the PMP22 gene. Research remains focused on understanding the molecular mechanisms of the disease. At DiseaseMaps.org, 89 community members share their experiences, which can be an invaluable resource for learning how others manage their symptoms.

Next steps

• Consult a neurologist to confirm a baseline for your nerve function.


• Work with an occupational therapist to identify and modify pressure points in your daily routine.


• Connect with the Hereditary Neuropathy with Liability to Pressure Palsies (HNPP) community at DiseaseMaps.org to share management tips with peers.


• Consult a genetic counselor to discuss family planning and inheritance patterns.
