Anxiety and agitation may be caused by a number of different medical conditions, medication interactions or by any circumstances that worsen the person’s ability to think. Ultimately, the person with dementia is biologically experiencing a profound loss of their ability to negotiate new information and stimulus. Situations that may result in agitation include:

  • Moving to a new residence or nursing home.
  • Changes in environment, such as travel, hospitalization or the presence of house guests.
  • Changes in caregiver arrangements.
  • Misperceived threats.
  • Fear and fatigue resulting from trying to make sense out of a confusing world.
