What is Neurofibromatosis?

21:55 - 4 May , 2021


It is a condition that produces tumors or neurofibromas in the nervous system tissues, which can affect brain areas, the spinal cord, or the upper and lower layers of the skin, which can cause from cosmetic problems to loss of function or movement of the affected nerve.

Neurofibromatosis is a hereditary pathology transmitted by one of the parents affected with this disease, which is classified into three types:

  • Type 1: is the most common and occurs during childhood.
  • Type 2: less common than the previous one, it appears in adulthood.
  • Schwannomatosis: it is rare and affects people between 20 and 30 years old.

Generally, neurofibromas are benign, but sometimes they can become cancerous, so it is important to diagnose and treat them promptly, preventing possible complications.

  • Cardiovascular conditions.
  • Chronic and disabling pain.
  • Epilepsy and other neurological disorders.
  • Hearing loss.

Diagnosis and treatment Neurofibromatosis

Once your doctor analyzes your symptoms and clinical history, they will perform a physical and neurological examination, in addition to requesting blood tests, computed tomography, MRI, vision, hearing, and balance tests, as well as genetic tests to help identify the type of neurofibromatosis you have.

Treatment focuses on controlling symptoms according to each patient’s specific case, so different procedures and therapies can be used, including medications, surgery to remove tumors, stereotactic radiosurgery, cochlear and brain stem auditory implants, as well as radiotherapy and chemotherapy, among others.

At the Neurological Center, a select group of highly trained and certified doctors in the various neurological specialties are ready to assist you with the quality and warmth that characterizes us.
