Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear. [3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [ 1 ]
Vertigo typically indicates a problem in a part of the vestibular system. [2] Other causes of dizziness include presyncope, disequilibrium, and non-specific dizziness.

Vertigo or dizziness; Weakness of limbs; Symptoms are frequently worsened by a Valsalva maneuver, or by being upright for long periods of time. The reason that being upright is problematic is that gravity allows increased interaction between the brain stem and the top of the spinal column, increasing symptoms.
There are several disadvantages proposed by Cohen for the classic maneuver. Patients may be too tense, for fear of producing vertigo symptoms, which can prevent the necessary brisk passive movements for the test. A subject must have adequate cervical spine range of motion to allow neck extension, as well as trunk and hip range of motion to lie ...
Vertiginous epilepsy has also been referred to as epileptic vertigo, vestibular epilepsy, vestibular seizures, and vestibulogenic seizures in different cases, but vertiginous epilepsy is the preferred term.
Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is an autosomal recessive late-onset heredodegenerative multisystem neurological disease. The symptoms include poor balance and difficulty walking.
Cervical spinal nerve C7 controls triceps and wrist extension. Cervical spinal nerve C8 helps control the hand. [18] The cervicocranial syndrome occurs when symptoms arise due to cervical vertebrae damage (misalignment, collapse, shift or disease, such as tumor) resulting in the improper functioning of the cervical spinal nerves.
