This research is backed up by the 15 years longitudinal electrophysiological study of 55 SCA2 gene cariers. During this time, 19 persons got sick and 36 remains healthy. Results proved the appearance of electrophysiological alterations before symtoms appear and precisely its early diagnosis can be the best way to delay the lounching of the desease.

Study of the saccadic ocular movement, demostrating alterations in the 100% of SCA2 , over a sample of 140 healthy persons. It is stated the significant correlation among the age the desease starts, the clinic scale and the size of the pathologic allele; evolution time is not correlated.

Markers which allow detecting neurophysiological alterations in absence of a desease clinical picture are detected. These studies have a high scientific novelty and, on the basis of the findings, different evoluting stages of the pathogenic SCA2 induced neurodegenerative process are described.

The greatest importance of this research lays on a superior characterization of the desease.
