As dementia progresses, your relationships are almost certain to change.

It is easy to feel isolated and alone if you or someone you care for has dementia. Keeping in contact with others is good for people with dementia because it can help keep them active and stimulated.

Some people find it difficult to talk about their own or a family member's dementia, or want to help but don't know how. If a friend or family member finds it hard to talk to you, don't lose touch.

Make the first move – explain that you still need to see them and tell them how they can help you. You may also find it helpful to join a local group of people with dementia and their families.

Good luck!

Thank you guys so much you have certainly helped, one follow question

which mixed method design can i use to further investigate the question

Living with dementia is likely to have an impact on the people around and relationships. Dementia can result in communication difficulties and memory loss, which can make sharing experiences and memories increasingly difficult. Many carers and family members can feel that as a person with dementia changes, due to their symptoms, that the heart of the relationship is lost.
