What is dementia?

Dementia is a common condition that affects one in three people over the age of 65 in the UK.

The term dementia describes a set of symptoms that usually includes loss of memory, difficulty with communication, reasoning and decision-making, changes in mood and behaviour and difficulty completing day to day activities.

Changes you may notice include:
  • Having difficulty remembering recent events or learning new information, but being able to recall things that happened in the past
  • Feeling confused or lost even when in a familiar environment
  • Forgetting the names of friends and relatives or of everyday objects
  • Finding it difficult to make decisions or plan future events
  • Losing the thread of whatís being said and needing prompts to maintain a conversation
  • Repeating things that have been said or done before
  • Losing things and thinking other people are to blame
  • Feeling irritable or upset and worrying about having memory problems
  • Needing help with looking after the house, shopping and paying the bills
  • Needing help with personal activities such as eating, washing or dressing
