Background and Purpose: The recognition of clinical features of transient vestibular symptoms (TVSs) preceding posterior circulation stroke (PCOS) would be informative to discriminate dizziness/vertigo due to vertebrobasilar transient ischemic attack from the acute transient vestibular syndrome. We sought to determine the prevalence and characteristics of TVSs preceding PCOS. Methods: We performed a prospective multicenter observational study that had recruited 447 patients with PCOS from referral-based 4 university hospitals in Korea. We investigated the timing, pattern, frequency, duration, and accompanying neurological symptoms of TVSs during the 3 months preceding PCOS. Results: The prevalence of TVSs preceding PCOS was 12% (55/447) during the previous 3 months. The TVSs preceding PCOS occurred within 1 week (33%), between 1 week and 1 month (16%), or between 1 and 3 months (51%). The TVSs were mostly dizziness/vertigo with (36%) or without (60%) imbalance, while the remaining 4% had an isolated imbalance. The dizziness/vertigo was spinning in 38% and was aggravated during head position in 45%. The duration of TVSs was mostly a few seconds (55%) or minutes (38%). Approximately 72% of the patients with PCOS had TVSs 1 to 5 times, while 16% had >10 times. Accompanying neurological symptoms, including headache, tinnitus, limb weakness, sensory change, dysarthria, visual field defect, and diplopia, were reported in 11%. Conclusions: Preceding TVSs can occur in 12% of PCOS during the previous 3 months. Isolated dizziness/vertigo of unknown cause needs to be considered as a vertebrobasilar transient ischemic attack symptom, especially in patients with vascular risk factors. The characteristics of isolated vestibular symptom in vertebrobasilar transient ischemic attacks is highly variable and atypical compared with other transient ischemic symptoms.

Background and Objective: Patients with transient ischemic attack（TIA）occasionally showed nonfocal symptoms, such as decreased consciousness, amnesia and non-rotatory dizziness. This study intended to evaluate the effect of nonfocal symptoms on the prognosis of patients with TIA. Methods: Data from the prospective hospital-based TIA database of the First Affiliated Hospital of Zhengzhou University were analyzed. The predictive outcome was stroke occurrence at 1 year. Cumulative risks of stroke in patients with and without nonfocal symptoms were estimated with Kaplan-Meier models. Results: We studied 1384 patients with TIA (842 men; mean age, 56±13 years), including 450 (32.5%) with nonfocal symptoms. In the first year after TIA, stroke occurred in 168（12.1%） patients. There was no difference in the risk of stroke between patients with both focal and nonfocal symptoms and patients with focal symptoms alone (11.8% vs 12.4%, log-rank; P=0.691). Conclusions: The occurrence of nonfocal symptoms did not increase the risk of stroke at one-year follow-up compared to the occurrence of focal symptoms alone.
