History of stroke is based on clinician review of self-report questions, neurological exam (when available), cognitive testing, and interview of participant. The clinician is first presented with an algorithmic diagnosis and has the ability to modify if necessary. For any given cycle, this variable indicates diagnosis of stroke in past history or in at least one follow-up cycle up to and including that cycle.
Clinician diagnosis of stroke:
The clinician rating is then dichotomized into history of stroke = 1 or no history of stroke = 0.
|0||No history of stroke - Diagnosis of possible or not present in all cycles|
|1||History of stroke - Diagnosis of highly probable or probable in at least one cycle prior to or in the given cycle|
