External signs of trauma are usually absent;
  8. If the dizzy only when changing position of the body, then we can talk about positional vertigo, it is benign. The disease is determined by a simple positional test;
  9. Basilar migraine begins with the patient for a few minutes or an hour before the headache begins to get woozy. The disease is accompanied by other neurological symptoms: tinnitus, vomiting, preceded by nausea;
