[...] Evidence suggests that DLB, Parkinson’s disease and Parkinson’s disease dementia may be linked to the same underlying abnormalities in the brain processing of alpha-synuclein. [...] The study, which examined the cells of living mice and postmortem brain tissue in humans, reveals that these proteins perform a crucial function by repairing breaks that occur along the vast strands of DNA present in the nucleus of every cell of the body. [...] Guidelines for diagnosing Parkinson’s disease dementia and DLB are: The diagnosis is Parkinson’s disease dementia when a person is originally diagnosed with Parkinson’s disease based on symptoms related to movement and dementia symptoms don’t appear until a year later or more.
