What is dementia?

Dementia is an umbrella term that covers a range of symptoms associated with a decline in cognitive function. This can include memory loss, difficulties with problem-solving, and changes in mood or personality. Unlike Alzheimer’s disease, dementia is not necessarily a progressive condition—some forms of dementia can actually be reversed with medical treatment.
