Caregiver Techniques for Coping with Delusions

Alzheimer's disease is a process of neural degeneration. As memory fails it is not uncommon for people with Alzheimer's to become suspicious of what is going on around them. A delusion can be thought of as a false belief that, even in the light of contradictory evidence, remains fixed. This is distressing for both the sufferer and their caregiver as delusions can lead to any number of false accusations.

The most common delusions are persecutory in nature. Beliefs about food or drinks being poisoned, being spied on, or things being stolen are typical. The person may believe their partner is having an affair. They may believe they are being held captive in someone's else's house. Some relatives find it very distressing when they are accused of being an imposter.

Coping With Delusions

  • Keep in mind that delusions are 'fixed'. This means any attempt to argue the case only causes more distress to everyone.

  • Inform your doctor as some variation in medication may help to settle things a little.

  • Sometimes just a little reassurance is sufficient to reduce concerns.

  • Sometimes the person may actually be correct, so don't assume delusional talk affects all aspects of their life.
  • Distraction Techniques:

  • Ask a question that you feel sure they will have a view on

  • Read out a section from the newspaper that is interesting

  • Ask if they will help you with some task

  • Ask the time
  • The nature of delusions and the way you cope with them will vary from person to person and also need to be adapted to the stage of Alzheimer's. It can also be useful to get ideas from healthcare professionals or your Alzheimer's Chapter or support group.
