Dizziness due to TIA and Stroke (dizziness-and-balance.com)
Controllable risk factors include being overweight, having high (> 140/90) or low blood pressure, heart disease, diabetes and smoking. Atrial fibrillation is a particularly important risk factor -- stroke occurs in 4.5% of untreated patients with atrial fibrillation per year. While uncommon, chiropractic neck manipulations can cause compression or tears of the vertebral arteries (Vibert et al, 1993; Smith et al, 2003), and for this reason, maneuvers involving neck "cracking" should be specifically avoided in individuals with vertigo. Whiplash injuries can also damage the vertebral arteries as the arteries traverse the vertebrae of the neck.
