Abstract

Ageing can be defined as progressive physiological changes in the organisms that lead to reduce the biological functions. The current study focus on the changes occurs in the brain during ageing. These changes includes physiological changes, Cellular, Structural, Chemical, Cognitive changes. The brain shrinks with increasing age and there are changes at all levels from molecules to morphology. Incidence of stroke, white matter lesions, and dementia also rise with age, as does level of memory impairment and there are changes in levels of neurotransmitters and hormones. Among these mentioned changes each change plays a key role in highlighting the ageing process at brain level. There are some neurological diseases such as Alzheimer's Disease, dementia, Parkinson’s, depression and may more are associated with brain ageing.
