Dizziness is a sensation caused by impaired or impaired spatial orientation, without the false or distorted sensation of motion. Its not used to describe pre-syncope or reality detachment, nor is it used to describe non-specific symptoms such as weakness, discomfort, or fatigue of the patient. Vertigo is a type of dizziness that refers to the sensation of self-motion felt in the absence of self-motion or the distorted sensation of self-motion felt during normal head movements. It is an intrinsic vestibular sensation, unlike extrinsic vertigo with an external visual sensation of motion, which is a vestibular visual symptom. In mild cases, it can be stopped by closing the eyes, but in severe cases, it is like riding in a boat or a car, or even unstable, and is accompanied by nausea, vomiting, sweating, and fainting.
