Depression and dementia are common in older adults. Depression is highly prevalent in the older population than in the general adult population. A WHO study says that 21.9% of the elderly in India suffer from depression. Meanwhile, there are 4.4 million older adults in India having some form of dementia.

What is Dementia?

Dementia is a process of cognitive decline. It is usually characterized by short-term and long-term memory loss. In extreme cases, there might be a complete character change in an individual with dementia. It is caused by different degenerative neurological diseases like Alzheimer’s disease. Dementia is irreversible in most cases. However, when it is caused by affective disorders like depression or bipolar disorder, it is reversible.

Cognitive decline due to dementia is virtually indistinguishable from depression. In the early stages, the symptoms of dementia are similar to depression. The common symptoms of both depression and dementia in the elderly are:

  1. Overpowering negative feelings (helplessness, worthlessness)
  2. Have negative opinions on almost everything
  3. Isolation and actively avoiding socialization
  4. Disinterest and inability to concentrate
  5. Unexplained urge to cry
  6. Sleeping unnaturally
  7. Loss of appetite and weight
  8. Fatigue and no motivation
  9. Little to no sense of direction
