Dementia is a degenerative disorder of the brain that severely affects the ability of a person to think and remember to the extent that daily functioning is impaired. Treatment of dementia in India is a viable option that is significantly less costly that the treatment options in other countries. Although dementia is a rigid disorder to cure, a large percentage of patients who come to India are able to recover from the symptoms and enjoy a re-integrated life.

Dementia represents a wide range of symptoms that involve the decline of memory and thinking skills severe enough to adversely affect the daily life of a person often making it very difficult for the person to perform daily activities. Dementia causes degeneration of the brain and if not treated leads to a serious loss of functioning in the patient that cannot be reversed. A feature of the disorder worth noting is that the sufferer’s consciousness is not affected. A person is typically diagnosed with dementia if there is a significant decline in cognitive abilities and functioning more than what is expected due to ageing. Dementia also has a substantial effect on the person’s caregivers.
The most commonly encountered form of dementia is Alzheimer’s disease which constitutes about 50% to 70% of cases. Alzheimer’s disease is a slow and progressive degeneration of the brain having unknown causes. Other common variants are vascular dementia (25%), Lewy body dementia (15%) and frontotemporal dementia. Less frequently encountered causes include normal pressure hydrocephalus, Parkinson disease, syphilis, and Creutzfeldt–Jakob disease among others. It is very much possible for a person to have more than one type of dementia. A small percentage runs in family. In the diagnostic statistical manual-5, dementia is classified as a neuro-cognitive disorder with varying degrees of affliction. Cognitive and behavioural interventions may be highly relevant in the treatment of symptoms of dementia. About 36 million people in the world suffer from dementia. With the increase in life expectancy of individuals, dementia is becoming more common in the population as a whole. People suffering from dementia are often restricted more than necessary causing concerns about violations of their human rights. More common in the old, dementia is a fairly common cause of disability in the elderly.
