Our brain needs a constant mind exercise which we could also characterize as a mind aerobics .

Find few minutes to train the brain of your senior .
Memory games:
***Finding opposites***
When you say the word, senior has to tell the opposite of this word.
Example: the trainer says new, the participant says old.

***Matching words with colours***
You say a certain word and the senior has to say the colour/colours in connection to this word.
