Dementia isn’t a joke – and people affected by it deserve to be treated with understanding and respect.

Ruchi recalls this story when she came back to her hometown after almost 4 years of staying abroad because of family disputes. She was sitting impatiently throughout the drive back home from the airport and kept fidgeting with her screen enabled toy gifted by her deceased Grandfather. Her impatience was palpable as she could not wait to see her old room, her old garden and most of all her old and lovely ‘Nani-mani’. That’s what she called her grandmother whom she had not seen since last 4 years. The taxi stopped right in front of the gated house and Ruchi saw her old garden fresh and blooming, her old room peeking at her from the window, and out walked her Nani-mani all laughing and smiling with no teeth in her jaw, without the dentures, and hugged Ruchi like she was waiting for her as a child waits for her mother. Like all grandmothers do, she admired the fact that how old Ruchi had grown and asked her a question which left Ruchi and her parents totally flabbergasted. “Where is your husband Richa”?

It would not be shocking to the entrepreneur Ruchi who now owns a company which enables old people to live an independent life, but for a 12-year-old girl that she was at that time, it was confusing and saddening as her Nani-mani could not recall her name, could not recognize her clearly and could not rightly keep up with the existing social norms. Ruchi’s Grandmother could recall only the old events and memories. For it had gotten erased from her recent memories all that could be registered. For her, Nani-mani kept asking about Ruchi’s husband during her entire stay for a month because she could not store any new information.

It is because she was suffering from dementia. A disease mostly affecting in the old age bringing impairment to Memory, Communication and Thinking. It makes memorizing new information very difficult. Patients often become forgetful, show decreased self-care, and have decreasing daily routine functions. They have trouble completing tasks that were once easy, have difficulty solving problems.

There are Problems with communications either written or spoken, confusion about places, people and events; visual changes and trouble drawing meaning out of images.
