Investigating associations between Parkinsonian symptoms and outcomes in people with dementia.

Stiffness in the limbs and slowed movements can be symptoms of Parkinson’s disease but are also commonly seen to co-occur with dementia. Some studies have suggested that people with dementia who have these symptoms may have a worse outcome, but this is still unclear. This study will develop a means to ascertain these symptoms when they are mentioned in routine clinical records and will then evaluate associations with dementia progression, hospitalisation and mortality.
