If dementia symptoms appear before or at the same time as people start to have movement problems, then a diagnosis of DLB is likely to be given.
If movement problems are present for a year or more before signs of dementia, then a diagnosis of Parkinson’s dementia is likely to be given.
If your GP suspects dementia, they may refer you to a memory clinic or another specialist clinic. You will be asked about your symptoms and medical history and may have a physical check-up and a memory test. They may also send you for tests like brain scans and blood tests. Together these tests will help to identify the likely cause of the memory and thinking problems.
Brain scans such as MRI (magnetic resonance imaging) or CT (computerised tomography) can help to rule out other causes of dementia. To help make a specific diagnosis of DLB, a type of scan called a DaT scan may be used to look for changes in the brain which are more common in this type of dementia.
It is important to get the right diagnosis so that appropriate treatments and help can be given. If you are worried about your health or someone else’s, you should talk to your GP.
