DEMENTIA AWARENESS

Abstract

Theory of functional consequences state that changes in body function accompany increasing age.These changes are caused by the aging process and the accompanying risk factors. The theory of biological aging explains the decline in cell function, which accelerate tissue damage and affects changes in the function of the human body system. The nervous system experiences changes in structure and function due to aging in the elderly, characterized by a decline in thinking and remembering processes

Dementia occurs as a result of a disease process that increasingly damages the brain over time. Dementia affects all groups of society and is not linked to social class, gender, ethnic group, or geographic location. Dementia is not a part of normal ageing. Although dementia is more common among older people, younger people can also be affected

Dementia is a major cause of disability and dependency among older people worldwide, and it has a significant impact not only on individuals but also on carers, families, communities and societies. Dementia accounts for 11.9% of the years lived with disability due to a noncommunicable disease (NCD) worldwide. Dementia leads to increased costs for governments, communities, families and individuals, and to loss in productivity for economies
