OBJECTIVESThe prevalence of balance problems in people with Alzheimer’s disease (AD) reaches 20-35%, and the number of patients is rapidly increasing. The terms Imbalance cover a variety of symptoms regarding disorders of spatial orientation, which can affect objectively the ability to achieve a posture, stable gaze, and normal gait. The aim of this study was to recognize main signs of this problem and determine rapid support recommendations.METHODS25 patient wish AD, with acute dizziness, admitted to Neurological department, were investigated. The main symptoms was acute vertigo with fall (n=10) and acute vertigo with unsteadiness (n=15). After exclusion of cerebral stroke (CS), investigation of balance system was provided by vestibular Romberg test, Fukuda step test, vestibular ocular reflex (VOR) and Dix–Hallpike maneuver (DHM).RESULTSIn all patients, CS was not revealed. In 12 cases, reason of dizziness was bilateral vestibulopathy, in 8 cases, - benign paroxysmal positional vertigo, in 2 cases, - vestibular neuritis and in 3 cases, somatosensory loss. In all cases, VOR and DHM were effective for balance recovery as well as first medical support. After the acute period (24hr) vestibular rehabilitation (VR) exercises were more effective than DHM.CONCLUSIONSDizziness/Imbalance in patients with AD, except of Stroke, can be treated with physical and pharmacologic therapy as well to help improve symptoms and reduce risk for falls.
