Dementia is not a disease in itself, but it is a broader term for a host of mental health issues that are often connected with the loss of memory and other cognitive abilities.æA person who suffers from dementia may often find it hard to carry on day to day tasks and activities. While there is no known cure for dementia, diagnosing the condition on time and taking the necessary steps can help contain the condition, and make it easier for the patient to adapt.
