Age-Related Diseases

Abstract

Age-related diseases occur frequently in the older population which signifies age as a major risk factor for old age disorders. Aging itself is not a disease but there are certain manifestations associated with aging that contribute to age-related diseases. There are many underlying causes that exacerbate age-related disorders, they include, inflammation, exposure to environmental pollutants, radiation, lifestyle, and dietary conditions. These factors tend to affect different people at a different rate and the disease progression depends on cellular aging and molecular pathways. Some of the prominent diseases associated with aging are cardiovascular, neurodegenerative, and metabolic in nature. Currently, many research models are proposed to determine the effect of aging on human body and how the rate of aging can be reduced by changes in lifestyle, specially controlling the social and mental stressors that catalyse aging by causing early cognitive impairment.
