Certain forms of behaviour are particularly common in people with dementia. If the person you are caring for has difficulty expressing him or herself in words, the unusual behaviour may become more extreme. By working out what each behaviour means, and finding ways to overcome the problem, the situation can become more manageable.

Common types of unusual behaviour include:

  • Repetitive behaviour
  • Restlessness
  • Shouting and screaming
  • Lack of inhibition
  • Night-time waking
  • Trailing and checking
  • Hiding and losing things
  • Suspicion
  • Sleeplessness and ‘sundowning’
