What are the blue flowers for?

It looks as though the badges are in support of those living with Alzheimer’s, with this week marking the Alzheimer’s Society annual conference.

It took place on May 14 with this week also marking Dementia Action week. 

The conference brought "together key decision makers who understand the urgent necessity of tackling dementia".

What is Alzheimer’s?

Alzheimer’s is a physical illness which causes damage to a person’s brain and eventually causes dementia.

Symptoms include memory problems, thinking and reasoning difficulties and language problems.
