^aP = 0.088 compared with 8 weeks before baseline. ^bP = 0.047 compared with baseline. ^cP = 0.045 compared with 8 weeks before baseline. ^dP < 0.0001 compared with baseline. ^eCalculated value for all 75 patients according the description in Materials and methods. *Significant change.

Calculated with the Wilcoxon test. MMSE, the Mini-Mental State Examination (0 to 30 points); a higher score indicates better cognition. AQT, A Quick Test of cognitive speed (measured in seconds); less time indicates better cognition.
