  • 1. HUMAN AGEING
  • 2. INTRODUCTION Ageing (British English) or aging (American English) is the accumulation of changes in a person over time. Ageing in humans refers to a multidimensional process of physical, psychological, and social change. Some dimensions of ageing grow and expand over time, while others decline.
  • 3. AIMS AND OBJECTIVES Ageing is the single greatest challenge our society is facing today. Recent breakthroughs have demonstrated that it is possible to combine a long life with the absence of age-related disease.
  • 4. THEORIES OF AGEING  Biological Theories      Wear and tear theory Cellular theory Auto-immune theory Genetic mutation theory Free radical theory  Psychosocial Theories       Disengagement theory Activity theory Continuity theory Social exchange and support Gero-transcendence Socio-emotional selectivity
  • 5. SUCESSFUL AGEING The concept of successful ageing can be traced back to the 1950s, and was popularised in the 1980s. Successful ageing consists of three components. 1.Low probability of disease or disability. 2.High cognitive and physical function capacity. 3.Active engagement with life.
  • 6. NORMAL CHANGES DURING AGEING
  • 7. PREMATURE AGEING DISEASE: PROGERIA Progeria (Hutchinson-Gilford Progeria Syndrome, HGPS, Progeria syndrome) is an extremely rare genetic disease wherein symptoms resembling aspects of aging are manifested at a very early age. The disorder has a very low incident rate, occurring in an estimated 1 per 8 million live births. It is a genetic condition that occurs as a new mutation, and is rarely
  • 8. MOLECULAR ASPECTS OF AGEING Telomere shortening during human ageing: Changes in mitochondria with ageing
  • 9. CAUSES OF AGEING
  • 10. CONTROL OF AGEING ANTI-OXIDANTS ENDOGENOUS EXOGENOUS
  • 11. COSMETIC UV-PROTECTION
  • 12. CONCLUSION     From these above discussions we can conclude that: We all change physically, as we grow older. Steps can be taken to help prevent illness and injury, and which help maximize the older person's independence, if problems do occur. There is no need for most people to fear getting older.
