As part of the Atherosclerosis Risk in Communities (ARIC) Study assessment of the etiology and sequelae of atherosclerosis, a standardized questionnaire on transient ischemic attack (TIA) and nonfatal stroke and a computerized diagnostic algorithm simulating clinical reasoning were developed and tested at the four ARIC field centers :
North Carolina ;
and Washington County,
The diagnostic algorithm used participant responses to a series of questions about six neurologic trigger symptoms to identify symptoms of TIA or stroke and their vascular distribution.
Among 12,205 ARIC participants reporting their lifetime occurrence of one or more symptoms probably due to cerebrovascular causes, nearly half (47%) reported the sudden onset of at least one symptom sometime prior to their ARIC examination.
Of those with at least one symptom, only 12.9% were classified by the computer algorithm as having symptoms of TIA or stroke.
Dizziness/loss of balance was the most frequently reported symptom (36%) ; 1.2% of these persons were classified by the algorithm as having a TIA/stroke event.
Positive symptoms of speech dysfunction were classified most often (77%) as being symptoms of TIA or stroke.
Symptoms suggesting TIA were reported more frequently than symptoms suggesting stroke by both sexes.
TIA or stroke-like phenomena were more frequent (p<0. (...)
