Do people with Parkinson's who experience cognitive impairment or brain fog have a higher risk of developing dementia?
Yes, experiencing cognitive impairment or brain fog can indicate a higher risk of developing dementia in Parkinson's disease. Many people with Parkinson's develop mild cognitive impairment (MCI), which involves problems with thinking and memory that aren't severe enough to affect daily functioning.
MCI is considered a state between normal cognitive aging and dementia. When MCI related to Parkinson's progresses, it can develop into Parkinson's disease dementia (PDD).
Research shows that between 18 percent and 41 percent of people with Parkinson's develop some form of cognitive decline or dementia. Some studies found that up to 19 percent of people already had mild cognitive impairment at the time of their Parkinson's diagnosis.
However, it's important to know that not everyone with MCI will progress to dementia. For those who do develop dementia, it typically takes time - the average is about 10 years between initial movement symptoms and a dementia diagnosis. Some people may take up to 20 years to progress from cognitive impairment to dementia.
If you're experiencing brain fog or memory issues, talk with your doctor about regular neuropsychiatric evaluations to monitor any changes. Early awareness can help you and your care team plan appropriate support and treatment options.
