Vertigo, instability and dizziness: Vertigo is usually rotational but can also cause the sensation of moving from one side to the other or falling to the ground. A typical vertigo attack is characterized by an intense feeling of spinning which coexists with intense sweating, nausea, vomiting, malaise, a feeling of fear and anxiety.

Labyrinth disorders, Vestibular system damage, Cerebellar tumor, Multiple sclerosis, Meniere’s disease, Vestibular migraine, Stroke, Diabetes mellitus.
