Contribution of Actigraphy and Recognition Video in Apathy Assessment of Alzheimer's Disease : Experimental Research

2014-08-27 03:16:39 | BioPortfolio

Summary

Neuropsychiatric symptoms form part of the clinical picture of Alzheimer's disease (AD) and other dementias. Irrespective of the severity of the disease, the most frequently encountered symptom is apathy. Apathy is increasingly diagnosed in patients with neurological and psychiatric conditions. Apathy is a disorder of motivation, defined as "the direction, intensity and persistence of goal-directed behaviour". Most of the current descriptions acknowledge this point and consider apathy in terms of a lack of goal-directed behaviour, cognition or emotion. The classical neuropsychiatric symptom assessments are subjective structured interview-based, using input from the caregiver and/or the patient. New technologies are likely to provide us with a more objective measure. An example is ambulatory actigraphy, consisting of a piezoelectric accelerometer designed to record arm movement in three dimensions.

The aim of the present study is to assess using actigraphy and video recording signal, AD patients with (n = 15) and without (n = 15) apathy and control subjects (n = 5) during an activity of daily living scenario .

Medical and Biotech [MESH] Definitions

The storing or preserving of video signals for television to be played back later via a transmitter or receiver. Recordings may be made on magnetic tape or discs (VIDEODISC RECORDING).

The measurement and recording of MOTOR ACTIVITY to assess rest/activity cycles.

Used with articles which include video files or clips, or for articles which are entirely video.

Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.

Vaccines or candidate vaccines used to prevent or treat ALZHEIMER DISEASE.
