Timing matters in Parkinson-related dementia. If parkinsonian motor signs come first and cognitive problems appear more than a year later, we classify the dementia as Parkinson disease dementia. That descriptor—Parkinson disease dementia timing—highlights the temporal relationship, which is why it is the best fit among the options. The other terms either imply the wrong sequence (early) or are too vague (later) or simply name dementia without tying it to the Parkinson disease timeline.
