P3‐174: ACTIGRAPHIC MOTOR ACTIVITY IN MCI PATIENTS CARRYING OUT SHORT FUNCTIONAL ACTIVITY TASKS

Cognitive and behavioral disturbances in MCI subjects usually accelerate loss of autonomy for instrumental activities of daily living.Additionally, ageing mightbeassociated with changes in motor abilities. The main aim is to assess motor activity in MCI subjects carrying out short functional activity tasks using ambulatory actigraphy. 20 MCI subjects and 14 cognitively healthy subjects wore a chest actimeter and carried out a 30-minute standardized scenario comprising directed activities (eecution of motor tasks), semi-directed activities (execution of actiities if daily living) and undirected activities. MCI subjects had significantly reduced motor activity while carrying out directed and semi-directed activities, compared to healthy subjects. The two subgroups did not differ on usual assessment scales for activities of daily liing (IADL). Motor activity assessment using actimetry might be an objective and more accuratetool, compared toclassical assessment questionnaires,for the detection of early motor changes during the evaluation of basic instrumental activities of daily livingin elderly non demented subjects with cognitive impairment.
