To be the earliest onset of illness, is often more rapid progression.

Currently, although there are lines of investigation open very promising, there is no treatment for this disease.


Genetic counseling (the carriers)

By molecular genetics techniques can be performed prenatal diagnosis.

Diagnosis and Treatment.


The diagnosis is made through the visit and clinical neurological exploration.

By molecular genetics techniques can be performed on presymptomatic diagnosis.

It is sometimes used tests, such as brain imaging (CT scan, MRI or other) to rule out other causes of the clinic.
