Alzheimer’s Patients’Assistance Models

Abstract

Alzheimer’s is a neurodegenerative disease which primarily effects the neurons in the human brain. The severity gradually increases over time, considered as the main cause for cognitive impairment in elderly people. Alzheimer's Disease has a long incubation period before clinical symptoms emerge, the available treatment can only delay the disease but not the progression. Hence the patients need assistance for their day to day activities. There are few neuropsychological tests like mini-mental state examination to determine the need and way of diagnosis and few systems have been proposed to help such patients. It is necessary to study the available systems for their efficiency, feasibility, speed and other factors necessary for comparison in order to understand the work done so far which will open ways for further research and improvisation of existing models and approaches. Therefore, in this paper we will review some of the devices, approaches and systems designed in order to help the Alzheimer's Patients’ with their daily activities.
