Hi deadinbed, so good to hear from you. This full article can be found on the Parkinson's Foundation website. I included a couple of excerpts but the full article is worth reading in my opinion.
Cognitive impairment is different from dementia, which is when cognitive impairments occur in more than one area of cognition, leading to more severe loss of intellectual abilities that interferes with daily, independent living. While approximately 50% of people with PD will experience some form of cognitive impairment, not all lead to a dementia diagnosis.

Cognitive issues are never too mild to address with your care team. A doctor can provide ways to help, often referring you to a psychiatrist, neuropsychologist, speech or occupational therapist for further evaluation and assistance. The neuropsychological evaluation can be particularly useful, especially in the early stages of a cognitive problem. Having this baseline test can help the doctor determine whether future changes are related to medications, the progression of the PD itself or to other factors such as depression.

Two long-term studies suggest that many people with PD will eventually develop a mild form of dementia as the disease progresses, usually many years after their initial diagnosis. One medication, Exelon (rivastigmine tartrate), can treat dementia in PD. Other medications are being studied.

There is more to this article but I hope you find this portion helpful. I sought the help mentioned in this article and I'm so happy I had this difficult conversation with my neuro because I believe my cognition has improved as a result of new services and effort on my part so PLEASE don't give up!
