Early-stage memory care/dementia.
Print word game sheets, explain the exercise and be on hand to help. It could be describing the word that is searched for or pointing out the first half of a word if needed.
Mid-stage memory care/dementia
Point out the first half of a word if needed. You can sound out the options verbally, pair the first part with the different options and get to the word that sounds right.
Encourage as much active participation as possible. If a person is unable to write, rather than you crossing out words as you find them (even if the person can’t write, they may be able to cross a word out), you can assist further by indicating with your finger where to put the X.
