• Don’t take mood swings personally—even though they seem directed at you. The root cause is what is happening in the brain rather than something you’ve done.

  • Be as supportive as possible and don’t pick fights.

  • Help the person compensate for memory loss by sticking to routines, leaving notes, repeating yourself, and issuing reminders.

  • It can help to name the feelings that than ignoring them. For example, “You seem upset today”.

  • Watch for signs of depression, which people with dementia are higher risk of developing.
