What symptoms are there?
The specific symptoms that someone with dementia experiences will depend on the parts of the brain that are damaged and the disease that is causing the dementia. A person with dementia will have cognitive symptoms (problems with thinking or memory) as well as often having changes in their mood. Dementia is progressive, which means the symptoms gradually get worse over time. How quickly dementia progresses varies greatly from person to person. As dementia progresses, the person may develop behaviours that seem unusual or out of character. The Alzheimer's Society has produced an informative factsheet that explains what dementia is and its causes and symptoms. It also looks at some of the different types of dementia. More information about the possible symptoms of each type of dementia can also be found on the NHS Choices website. On the Alzheimer's Research UK website you can also tour the brain and discover what different areas of the brain do and how they can be affected by dementia.
Worried about your memory?
If you are worried you may becoming increasingly forgetful, you should visit your GP to talk about your symptoms. Your forgetfulness could be caused by a number of factors, not necessarily dementia. If you are concerned someone you know may have dementia and are unsure how to help them, you can find useful information about this by visiting the NHS Choices website. The Alzheimer's Society's top tips can also provide help with starting the conversation about your concerns with the person.Last reviewed: 11/03/2015
