What would you do if you were concerned Peeshe lacked mental capacity to make decisions regarding his care and treatment?

Arrange for him to have a mental capacity assessment to determine whether he had capacity to make decisions in this area. Remember he may still have capacity to make decisions regarding other aspects of his life

Consider the impact of Peeshe’s dementia on his wife, children, grandchildren, and friends and neighbours.

This may be difficult to answer as there is not enough detailed information on the type of relationships he had with various people in his life. If he was close to them then you can only speculate that it would be very profound indeed. Loved ones seeing their partner losing skills and memory can be very distressing. Behavioural changes can also add much stress to relationships. On the other hand if Peeshe was not well liked or respected then others in his life may take a different view on his dementia. For example, neighbours may be relieved if he can no longer sing or use his love of music to entertain others.  You can find further information on the impact of dementia on carers at this link 

Who is in the best position to safeguard Peeshe?

Usually it would be people who are closet to him. For example, his wife and children. However, everyone has a responsibility and neighbours and close friends can provide support and keep a watchful eye if he wanders off from the family home. Remember, safeguarding should be a proactive activity so being positive, offering support and encouragement is vital to adults at potential risk of harm.
