How is giddy cannot rise to return a responsibility

First: dizziness, also known as vertigo, is a subjective sensory abnormality. It can be divided into two categories: one is rotational vertigo, which is mainly caused by vestibular nervous system and cerebellum dysfunction, mainly by the feeling of dumping, feeling self shaking or scene rotation. The second is general dizziness, which is mainly caused by some systemic diseases, with dizziness as the main feeling.

Second: it's related to our inner ear and brain stem. There is a structure called vestibule in the inner ear, which is composed of anterior, outer and posterior semicircular canals, crista ampullaris and utricle. There is lymph flow in the semicircular canals. The cells at the end of vestibular nerve sense the spatial position of the body, and transmit the information into the brain and into the vestibular nucleus of brain stem. Vestibular and vestibular nucleus lesions, such as inflammation, ischemia, tumor cyst compression, all cause the illusion of position and dizziness.

Third: dizziness is related to our vision. We can see the position of objects through our eyes. When our vision is wrong, there will be hallucination of the position of objects, leading to dizziness. For example, ametropia, optic neuritis, visual cortex ischemia, and even visual cortex damage appear cortical blindness.
