Dementia Test Online

The most common early sign of dementia is memory impairment, mainly problems with remembering newly learned information (short term memory loss). Other early signs of possible dementia can include problems with executive function (planning & reasoning skills), and getting lost in familiar surroundings.

Occasional forgetfulness is not the same as memory loss. Normal age related memory lapses include forgetting what you walked into a room for, and sometimes misplacing personal items. More serious memory problems could be an early warning of Alzheimer’s/dementia – see this description of normal age related memory changes for more detail.
