Mean age and mean disease duration were 60.9-year old and 10.4 years, respectively.
Mean disease duration was 14.1 years (12.3 the CCH group and 15.7 in the ECH group).
The mean disease duration at first SPECT imaging ranged from 2.4 to 7.9 years.
The mean age was 53.8 years (range, 29 75) and the mean disease duration was 11.2 years (range, 2 38).
Among the 26 participants reporting an onset date for their migraines, the mean disease duration was 24 years.
We studied 27 RRMS (mean disease duration, 5.6 years), 10 SPMS (mean disease duration, 12.7 years), and 8 healthy controls.
Mean disease duration at time of the study was 5.5±3.3 years.
The mean disease duration even for the relapsing remitting group was over 15 years.
The patients consisted of 90 females (mean age 61, age range 24 87, mean disease duration 10 years (0 41 years)) and 40 males (mean age 59, age range 25 84, mean disease duration 9 years (0 39 years)).
34 prospective patients (24 women, 10 men, 22 65 years, Ø 41 years, mean disease duration 6 years) were examined.
The patients' mean age was 64.8±11.8 (SD) years and mean disease duration was 7.9±7.8 years.
