At the time of diagnosis, people with dementia reported significantly more pain than people without dementia.
The researchers note that, because the brain changes associated with dementia start decades before diagnosis, it is unlikely that pain causes or increases the risk of dementia.
Instead, they suggest that chronic pain might be an early symptom of dementia or simply correlated with dementia.
Future studies that include data on the cause, type, location, and characteristics of pain and the type and seriousness of a patient’s dementia could help define in more detail the link between dementia and pain.
