Understanding Neurofibromatosis: Causes, Symptoms, and Treatment


Known as an uncommon genetic disorder that typically disturbs the normal growth of nerve cell tissues, neurofibromatosis has been the subject of immense medical research and study. This genetic disease primarily comes in three different types, each with its own unique set of symptoms and potential complications.

The Different Types of Neurofibromatosis

There are primarily three major types of this genetic disorder: Neurofibromatosis type 1 (NF1), Neurofibromatosis type 2 (NF2), and Schwannomatosis.

NF1, the most common, usually makes its appearance in childhood and is characterized by changes in skin coloring and benign tumors along the nerves.

NF2, while less common, typically surfaces in late teen years or early adulthood, and is marked by tumors in the spinal cord or brain.

Schwannomatosis, the rarest, causes chronic pain due to tumors called schwannomas, lacking the distinctive skin changes seen in NF1 and NF2.

Causes of Neurofibromatosis

Neurofibromatosis is primarily caused by mutations in specific genes. For NF1, the mutation occurs in a gene on chromosome 17, while for NF2, the alteration takes place in a gene on chromosome 22.

Schwannomatosis is a bit complex since it can be related to mutations in several genes. It’s extremely important to note that these mutations can either occur spontaneously or be inherited from a parent.

Symptoms Associated with Neurofibromatosis

The symptoms vary greatly for each type of neurofibromatosis.

For NF1, the symptoms include flat, light brown spots on the skin, presence of freckles in the armpits or groin area, tiny bumps within nerves of the skin, and soft bumps on or under the skin.

NF2 patients can experience balance difficulties, gradual loss of hearing, vision changes, facial drop, numbness and weakness in the arms or legs.

Schwannomatosis symptoms, on the other hand, are primarily characterized by chronic pain that can occur anywhere in the body.

Diagnosis of Neurofibromatosis

Diagnosing neurofibromatosis requires a comprehensive evaluation that includes family history, a physical examination, and a series of tests. These can range from genetic tests, imaging tests, eye examinations, hearing tests, to even utilizing diagnostic criteria.

Treating Neurofibromatosis

Although there’s no definitive cure for neurofibromatosis, treatments vary widely and often focus on controlling symptoms and managing complications. Surgical removal or reduction of tumors, pain management, monitoring and management of cardiovascular issues, and physical therapy for mobility issues form a crucial part of this procedure.

Living with Neurofibromatosis

Living with neurofibromatosis certainly has its challenges. Nonetheless, it’s crucial for patients to regularly follow up with their healthcare provider to monitor for new symptoms or complications. Joining support groups, seeking counseling, and educating oneself about the disorder can significantly help in dealing with the physical and emotional challenges posed by the disease.


The journey of understanding neurofibromatosis is vast, but it’s essential for patients and their families. Through continual research and advances in medical technology, we are inching closer to more effective treatments, and possibly, a cure for this disorder. Until then, patient’s resilience, healthcare providers’ concerted efforts, and society’s understanding continue to be the driving force behind battling neurofibromatosis.
