Approximately 40% of individuals may have mild cognitive impairment at the time of Parkinson's disease diagnosis.

“essentially they're reporting about 40 even upon diagnosis may already have some cognitive issues now that's not the same thing as dementia so this is called mild cognitive impairment and mild cognitive impairment is defined by the idea that a person may be noticing some memory related issue or their family members noticing that but they're not functionally impaired meaning they can do all their adls but they themselves are noting this and and we can actually pick that up on some diagnostic testing as well”
