Vertigo might be another symptom of stroke. If you feel like losing the balance or ability to control every body function, you should know how this phenomenon is usually called. It’s vertigo. Many people confuse this symptom with being poisoned. However, if you also feel dizzy, the sign may be associated with the stroke. Those could be just viral attacks. Poisonous air, food, or drugs are not always the only sources of intoxication. It is better to see a doctor anyway.
