Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

If I treat neurofibromatosis will it be gone, or do I need to keep worrying? I have so much on my mind.

Its In your genes: If you do have one of the many forms of nf you have it forever. Treatment programs focus on early detection of some of the possible complications (abnormal growths in vital areas) & educating you on your form. Many cases represent new mutations. Some are inherited from parents who never knew they carried the genes. Your dr can refer you to a genetic counselor to begin your orientation. ...Read more

Is it normal for optic nerve tumors to cause impairment in vision (neurofibromatosis 1)?

Is it normal for optic nerve tumors to cause impairment in vision (neurofibromatosis 1)?

Usually: The symptoms are caused by tumor growing and pressing on the optic nerve and nearby structures. Symptoms may include: •involuntary eyeball movement, eyes bulging outward, squinting, loss of vision in one or both eyes leading to eventual blindness this may be losso of peripheral vision or more general loss. ...Read more

Could anybody get neurofibromatosis?

Congenital condition: Neurofibromatosis is an autosomal dominant genetic disease, meaning if one of your parents has the disease you have a 50% chance of inheriting the disease. There are also instances of spontaneous mutation in about half of cases where an individual has the disease but it is not seen in family members. Either way, you are born with the condition, but may not see symptoms until later. ...Read more

What is the history of neurofibromatosis?

Long history: Von Recklinghausen's (NF1) has pictorial history, dating back to thirteenth century. In 1768, Akenside published a scientifically-based description of NF1, recognizing that scholars such as Parè and Aldrovandi, in fact suffered from a disorder of the nerves. Neuromas of NF1 were first detailed by Smith in 1849, but Frederick von Recklinghausen is credited with its discovery and coined the name. ...Read more

What symptoms make you think of neurofibromatosis?

There are 2 froms.: Nf-1 is characterized by tumors on small nerves under the skin. The worst form of this was depicted in a movie called the "elephant man". Tumors on spinal nerves can cause numness and weakness of certain arm or leg muscles. Nf-2 is characterized by brain tumors. The most common form is a tumor on both hearing nerves. Hearing loss, dizzyness, and ringing in the ear are common symptoms of nf-2. ...Read more

What is the definition or description of: Neurofibromatosis?

Genetic disorder: Neurofibromatosis is a set of genetic disorders which emanate from mutations from either the NF1 or NF2 genes. There is a characteristic phenotype for each, which derives the diagnostic criteria for the diseases. NF1 is associated with a number of tumor types, while NF2 is particularly associated with acoustic neuromas. ...Read more

Is there any research is being done on neurofibromatosis (nf)?

Yes: Research teams located the exact position of the NF1 gene on chromosome 17.Product of NF1 gene is a large and complex protein called neurofibromin, which is primarily active in nervous cells as a regulator of cell division. Intensive efforts have let to the identification of the NF2 gene on chromosome 22. NF2 gene product is a tumor-suppressor protein called merlin. Ongoing research to discover genes ...Read more

Is there a cure or treatment for neurofibromatosis?

Neurofibromatosis: There is no cure for neurofibromatosis and the goal of treatment is to relieve symptoms. Painful cutaneous and subcutaneous tumors and those that occur on visible areas of the body may be removed surgically.
