Main clinical and neuroimaging predictors of disability progression in multiple sclerosis
Keywords:relapsing remitting multiple sclerosis, clinically isolated syndrome, disability progression, clinical and neuroimaging factors
The objective: identification of the main predictors of progression of disability in patients with multiple sclerosis (MS ) , depending on the clinical and neuroimaging factors.
Patients and methods. The data presented was collected during a ten year observation of 180 patients with relapsing remitting multiple sclerosis (RRRS) from the first clinical signs of the disease (CIS). Age surveyed ranged from 18 to 42 years old with a mean of 31,5 ± 1,18 years . We determined clinical and neuroimaging factors of active dis ease course with development of moderate disability symptoms in dif ferent periods of the study.
Results. High relapse rate in the early years of the disease is significant factor in achieving a moderate level of disability as per EDSS scale in the long run – after 8 to 10 years since onset.
Conclusion. The main neuroimaging predictors of disability progres sion in RRRS is the presence of 9 or more T2 lesions with CIS, sub tentorial and periventricular localization of lesions, and the number of T2 cells ≥3 mm.
