Social impact of an ageing society

Anti-ageing therapies

Particular efforts are being made to learn more about possible life prolongation and more attention is being given to life extension science. Premature ageing diseases (progeria, Werner syndrome, Senescent accelerated mice), animals genetically modified by insertion or inactivation of genes (transgenic animals) and in vitro cell cultures allow identification of several mechanisms involved in life extension. Increased capacity to resist oxidative stress is particularly important.

There is compelling evidence that dietary restriction can lead to better health and longer life in laboratory animals.

Diet

Equilibrated diet is a source of proteins, sugars, lipids, vitamins and naturally occurring anti-oxidants.

The unbalance in the dietary supply of sugars, proteins, and lipids may initiate major health problems including obesity, coronary heart disease, cancer, diabetes mellitus, high blood pressure, stroke, gout, and gall bladder disease. In old people a lack of vitamins causes vitamin deficiency.

You can test your own sugar sensitivity.

Antioxidants are natural substances that may help prevent ageing-related diseases.

Antioxidants fight ROS and can prevent partially ROS-initiated diseases. Some antioxidants, such as the enzyme superoxide dismutase, catalase, glutathinone peroxydase are produced in the body. Others come from food.

With age, the efficiency of antioxidant enzymes declines and ROS induced damage increases. To compensate for antioxidant enzyme failure, food supply in antioxidant is necessary. The best way to get antioxidants is by eating fruit and vegetables rather than by taking vitamin pills but more research is needed before specific recommendations can be made.

You can perform a nutrition quiz.

Hormone replacement therapy

Hormone replacement therapy (HRT) can ease symptoms of menopause and protect against risk of heart disease, stroke, and osteoporosis.

However, all treatments related to hormone replacement should be undertaken with caution since several side effects may be observed.

Memory loss prevention

Memory loss is not inevitable. Some simple devises may help to keep the memory intact: writing things down, always putting frequently used items in the same place, repeating information that one needs to remember over and over again, making associations and relying on situation to trigger the memory (for example, leaving an umbrella by the door).

Memory test : with Shock wave remote; without plugging.

Physical exercise

Physical exercise is essential for a successful ageing. It helps to keep cardiovascular fitness reduces risks of osteoporosis and increases the sense of equilibrium

Social impact of an ageing society

An ageing population certainly has an impact on society. The presence of an increasing number of old people may provoke intergenerational tensions by generating competition between the young and old for a limited amount of resources, (economical, ecological, social, individual and political). This tension may compromise the intergenerational equity and the global sustainable development.

In order to deal with an ageing population and create an ageing " society for all ages ", it is necessary to constantly review and revise social systems relating to employment, pensions, medical care, welfare, education, social involvement and living environments so as to adapt them to an ageing society. To achieve this goal, both national and local governments, as well as corporations, local communities, households and individuals, must co-operate.
