Dementia is an umbrella term for all the progressive neuro-degenerative conditions which affect your brain and are severe enough to interfere with your normal functioning. It generally affects the elderly population above the age of 60 but is not a normal process of aging. Unfortunately there is no cure for dementia, but certain conditions are reversible. If any form of dementia occurs at an age less than 60 years, such cases are termed as early onset.

Alzheimer’s disease is one of the most common form of dementia, amounting to 60-70% of the cases. Other conditions include vascular dementia, Lewy body dementia, mixed dementia, Creutzfeldt-Jakob disease, Parkinson’s disease dementia and Huntington’s disease.

According to a World Health Organization (WHO) report, at present there are more than 40 million people suffering from dementia globally. This number will increase to an estimated 75.6 million in 2030, and 135.5 million in 2050. Much of the increase is expected to be in developing countries.
