Dementia is caused by a disease or condition affecting the brain.
Alzheimer's disease is the most common type of dementia, but there are different types - some far rarer than others.
Symptoms normally include memory loss and difficulties with thinking, problem-solving or language. They get worse with time, also affecting people's mood and behavior. They can become frustrated, irritable, anxious or easily upset and sad.
Around 850,000 people are affected by dementia in the UK. They need support and help from the early stages of this vulnerable situation.
