Neurofibromatosis: Symptoms and Treatments

Neurofibromatosis: Symptoms and Treatments

Neurofibromatosis is a rare genetic disorder that usually manifests itself with the presence of dermatological (skin) lesions and / or involvement of the nervous system.

There are no symptoms of neurofibromatosis. several ways in which neurofibromatosis can manifest in the nervous system, sometimes benign or malignant, but usually this is due to the finding of tumors that can compromise hearing, vision, motor, language, among others. These tumors are known as gliomas, meningiomas, or schwannomas.

Types of Neurofibromatosis

  • Neurofibromatosis type 1 : most frequent, beginning in childhood and resulting from a mutation (genetic alteration) in chromosome 17. Levi coffee-and-milk stain on the skin of the affected person, in addition to the fibroids that are tumors that grow as nodules from the lower layers of the skin
  • Neurofibromatosis type 2 : less common, due to genetic alterations in chromosome 22 and usually manifests with hearing impairment due to the growth of benign tumors in the vestibulocochlear nerve, which is responsible for hearing.

Symptoms of Neurofibromatosis

Symptoms of neurofibromatosis will depend on the type of disease and the presence or absence of tumors in the system nervousness beyond skin changes. There may be large variations between individuals, some with many symptoms and others with almost no symptoms from the disease.

In cases of Neurofibromatosis type 1, the most common symptoms are brown spots on the skin, small lumps under the skin, and development, and deformation of bones.

In cases of Neurofibromatosis type 2, the most common symptoms are balance difficulties, gradual reduction of vision or hearing, spinal problems such as scoliosis and vision and hearing problems.

However, the researchers believe that the mosquito is susceptible to the virus more in rural and wild environments. It is believed that it may have been infected by monkeys in the wild, but its potential as a yellow fever vector is not yet known. "This finding is important because Aedes albopictus may establish an intermediate (rural) cycle, of the Yellow Fever in the Americas, similar to what occurs in Africa, "says Pedro Vasconcelos, director of the Evandro Chagas Institute, in an interview with the Institute's website.
