Dementia

Dementia is not a disease itself. It is a collection of symptoms that result from damage to the brain caused by different diseases such as Alzheimer's. These symptoms can vary according to the part of the brain that is damaged.

There are some common early symptoms that may appear sometime before diagnosis of dementia, these include:

  • Memory loss
  • Difficulty concentrating
  • Finding it hard to carry out familiar daily tasks, such as getting confused over the correct change when shopping
  • Struggling to follow a conversation or find the right word
  • Being confused about time and place
  • Mood changes
These symptoms are often mild and may worsen very gradually. It is often termed “mild cognitive impairment” (MCI) as the symptoms are not severe enough to be diagnosed as dementia.

You may not notice these symptoms if you have them, and family and friends may not notice or take them seriously for some time. In some people, these symptoms will remain the same and not worsen. but some people with MCI will go on to develop dementia.

Dementia is not a natural part of ageing. This is why it's important to talk to a GP if you are worried about memory problems or other symptoms as soon as possible.
