How we can help

Visual Hallucinations: greet person in their line of sight so they look at you, not the hallucination. remember to use supportive stance-one foot front and weight on back leg. turn body slightly to the side. arms relaxed and in view. change the subject and keep them looking at you or something they like

Apathy: find out things they have been interested in the past and engage them in it or talk about it. or engage them in something new and simple tiredness and varying sleep cycles: don’t get too caught up in night and day for sleep. allow to sleep when tired, engage additional care partners if necessary when they are awake at night

Refusal of Care: if care is refused, reapproach after going to do something else or ask someone else to approach and attempt

Focus on what the person can do!
