Behavioural Changes

Topic Overview

Personality word cloud

  • Most, but not all, behaviour changes seen in persons with dementia are thought to be a response to a cue or trigger they experience.
  • ‘Responsive behaviours’ are being recognized as a form of communication and the persons’ best attempt to respond to their current situation and communicate their unmet needs.
  • Some of these behaviours are disruptive and can be a great burden for family caregivers.
  • There are numerous strategies that can be tried to avoid or reduce disruptive behaviours.
  • Successful management of disruptive behaviours requires a team approach with health care providers and caregivers to understand a loved one needs that may be behind these dementia related behaviours.

  • sleep disturbance
  • increased agitation in the late afternoon or evening (sundowning)
  • repeating sounds words or phrases
  • physical aggression
  • arguing
  • wandering
  • showing signs of depression
  • resisting help with activities like dressing, washing, toileting, eating
  • suspiciousness
  • accusations (e.g., theft, infidelity)
  • delusions
  • hallucinations
  • paranoia about having clothing, jewelry or money stolen

Over time, these behaviours place a growing burden on caregivers. Successful management means making adjustments in the understanding of what can influence or trigger behaviours and implementing approaches to care tailored to the individual with an emphasis on their remaining abilities and strengths.

Ways to Avoid or Reduce Disruptive Behaviours

Ways to avoid or reduce these behaviours include:

  • set up daily routines
  • avoid big changes in the environment as this may trigger agitation
  • provide a calm and safe environment (e.g. avoid moving furniture, avoid throw rugs and trip hazards, reduce loud and unexpected noises)
  • encourage physical activity during the day, such as exercises or walks, to help work off anxiety and excessive energy
  • respond to your family member's emotions, provide reassurance, touch, and hugs
  • avoid arguing as this may increase agitation; instead change the subject and engage the patients’ long term memory such as asking about a spouse, children or a favorite sport
  • be empathetic to your family member's problems
  • maintain a consistent approach among all caregivers in managing the behaviour
  • consider whether a day program may be helpful, as program staff are usually familiar in dealing with behavioural issues and it will provide a break for you, the caregiver
What to Do

  • Never change medications or add new ones – this is the responsibility of the health care provider.
  • Ask others who have contact with your family member to see if they have noticed any changes in behaviour.

  • Some newer anti-psychotic and antidepressant medications, as well as the use of cognitive-enhancing drugs, have been shown to be helpful.
