What is dementia?

We explain more about what dementia is, how it affects people and how this might impact on your life.

Your brain is the most complex part of your body. It’s where sights, sounds and sensations are interpreted, helping you to make sense of the world. It’s where memories are stored, emotions are felt, problems are solved and decisions are made. It’s also the control centre for everything you say and do. Your brain is the part of your body that makes you, you.
