What is dementia

The word “dementia” is an umbrella term used to describe a set of symptoms, including impairment in memory, reasoning, judgment, language and other thinking skills.

Dementia usually begins gradually, worsens over time and impairs a person’s abilities in work, social interactions and relationships.

Often, memory loss that disrupts your life is one of the first or more recognisable signs of dementia.

Other early signs might include asking the same questions repeatedly, forgetting common words when speaking, taking longer to complete familiar tasks, misplacing items in inappropriate places.
