Presenting symptoms and onset-to-arrival time in patients with acute stroke and transient ischemic attack.
Delayed arrival to the emergency department (ED) precludes most stroke patients from receiving thrombolytic treatment. Our objective in this study was to examine the association between presenting symptoms and onset-to-arrival time (ie, time between onset of symptoms to arrival at the ED) in a statewide stroke registry. Demographics, clinical data, and presenting symptoms were collected for patients with acute stroke or symptomatic transient ischemic attack (TIA) admitted to 15 Michigan hospitals (n = 1922). ⋯ Difficulty with walking, balance, or dizziness (12%), confusion (9%), loss of consciousness (6.7%) and falls (3.4%) were associated with lower likelihood of arriving within 2 hours (walking: aOR, 0.7; 95% CI, 0.4-1.0; confusion: aOR, 0.5; 95% CI, 0.3-0.8; consciousness: aOR, 0.5; 95% CI, 0.1-0.9; falls: aOR, 0.4; 95% CI, 0.3-0.9). Presenting symptoms were strongly associated with time of arrival; patients with unilateral symptoms and speech difficulties were more likely to seek care early. Future studies should consider including more specific patient-level data to identify psychosocial and behavioral aspects of recognition and action to stroke symptoms.

Factors associated with misdiagnosis of acute stroke in young adults.
Misdiagnosis or delayed diagnosis of acute ischemic stroke can result in neurologic worsening or a missed opportunity for thrombolysis. Because stroke in young adults is less common than stroke in the elderly, we sought to determine clinical characteristics associated with misdiagnosis of stroke in young adults. Patients from the prospectively maintained Young Stroke Registry in our comprehensive stroke center were reviewed. ⋯ Patients presenting with vertebrobasilar territory ischemia have a greater rate of misdiagnosis. Our study demonstrates the increasing need for "young stroke awareness" among emergency department personnel. Initial misdiagnosis can potentially lead to a lost opportunity for thrombolysis in otherwise good candidates.
