Putamen atrophy and its long-term progress during disease course were recently
shown in patients with multiple sclerosis (MS). Here we investigated
retrospectively the time point of atrophy onset in patients with
relapsing-remitting MS (RRMS). 68 patients with RRMS and 26 healthy controls (HC)
were admitted to 3T MRI in a cross-sectional study. We quantitatively analyzed
the putamen volume of individual patients in relation to disease duration by
correcting for age and intracranial volume (ICV). Patient's relative putamen
volume (RPV), expressed in percent of ICV, was significantly reduced compared to
HC. Based on the correlation between RPV and age, we computed the age-corrected
RPV deviation (?RPV) from HC. Patients showed significantly negative ?RPV.
Interestingly, the age-corrected ?RPV depended logarithmically on disease
duration: Directly after first symptom manifestation, patients already showed a
reduced RPV followed by a further degressive volumetric decline. This means that
atrophy progression was stronger in the first than in later years of disease.
Putamen atrophy starts directly after initial symptom manifestation or even years
before, and progresses in a degressive manner. Due to its important role in
neurological functions, early detection of putamen atrophy seems necessary.
High-resolution structural MRI allows monitoring of disease course.
