Head | Neurology | Neurofibromatosis (Disease)


Neurofibromatosis is a genetic disorder of the nervous system. It mainly affects how nerve cells form and grow. It causes tumors to grow on nerves.

There are three types of neurofibromatosis:

(1) Type 1 (NF1) causes skin changes and deformed bones and usually starts at birth.

(2) Type 2 (NF2) causes hearing loss, ringing in the ears and poor balance. It often starts in the teen years.

(3) Schwannomatosis causes intense pain. It is the rarest type.

Causes and Risk factors

You can get neurofibromatosis from your parents, or it can happen because of a mutation (change) in your genes. Once you have it, you can pass it along to your children.

Diagnosis and Treatment

There is no cure. Treatment is aimed at controlling symptoms. Depending on the type of disease and how bad it is, treatment may include surgery to remove tumors, radiation therapy and medicines. Three distinct types of neurofibromatosis exist, each with different signs and symptoms.
