Ageing is a natural process characterized by progressive deterioration of biological functions. Ageing causes both morphological as well as biochemical alterations in various body organs leading to deterioration of health. Proteins, enzymes and neurotransmitters are affected, which in turn can result in dysregulation of various pathways. WHO has reported that by 2020, three quarters of all deaths in developing countries will be age-associated. Currently more than 300 theories exist to explain the phenomenon of ageing; amongst them the oxidative stress theory of ageing is most studied and accepted for the molecular basis of ageing. All these processes can progress at an unprecedented pace on contact with triggering factors, leading to the development of pathological ageing. The probability of developing neurodegenerative and metabolic disorders is relatively high under such circumstances. This review emphasizes the theories and mechanisms of ageing and an overview on the aspects of age associated biochemical changes and the implications on the brain, liver and various organ systems.
