Purpose: The aim of the study was to compare balance performance in mild-moderate stage Alzheimer's disease (AD) patients and healthy peers using clinical balance tests and computerized posturography. Methods: We recruited 95 patients and divided them into two groups; 51 patients (62 % (n=32) female) in AD group and 44 patients in healthy controls group (50 % (n=22) female). Berg Balance Scale (BBS) and Timed Up & Go (TUG) test were performed. Computerized posturography was performed. Results: The mean age was 77.2±5.5 years in the AD group and 73.8±4.4 years in the control group (p<0.001). Sensory organization test composite equilibrium score (60[30-81], p<0.001), step quick turn-sway velocity (69.2 [38.2-95.8], p<0.001) and step quick turn-time (3.8 [1.6-8.4], p<0.001) were significantly impaired in mild-moderate stage AD patients. Berg Balance Scale (50 [32-56], p<0.001) and TUG test (13.0 [7.0-25.7], p<0.001) results were worse in AD. Conclusions: Computerized posturography measures were impaired in mild-moderate AD patients. The results highlight importance of early screening for balance and fall risk in AD patients. The study provides multi-dimensional and holistic assessment of balance performance in early-stage AD patients. Alzheimer's disease patients at earlier stages are prone to fall risk and should be evaluated accordingly.
