According to the National office for statistics, dementia is the second biggest killer in the UK after heart disease.
Although there are some common symptoms of dementia, such as memory loss, specific symptoms often depend on the part of the brain affected by the condition.
Alzheimer’s disease, one of the most common causes of dementia, occurs when an abnormal protein surrounds brain cells, damaging their internal structure.
Problems with day-to-day memory tend to be one of the first signs of the condition, but other symptoms may include difficulty finding the right words, making decisions, or perceiving things in three-dimensions.
