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] This can occur with turning in bed or changing position. [3]
Vestibular dysfunction can exist unilaterally, affecting only one side of the body, or bilaterally, affecting both sides. [2] The most commonly known vestibular disorder is called Benign Paroxysmal Positional Vertigo (BPPV). The BPPV is characterized by a temporary dizzy feeling associated with blurred vision in relation to certain head positions.
Vertigo typically indicates a problem in a part of the vestibular system. [2] Other causes of dizziness include presyncope, disequilibrium, and non-specific dizziness. [2] Benign paroxysmal positional vertigo is more likely in someone who gets repeated episodes of vertigo with movement and is otherwise normal between these episodes. [9]
Information from the semicircular canals reflects rotational movement of the head. Both are necessary for the sensation of body position and gaze stability in relation to a moving environment. Axons of the vestibular nerve synapse in the vestibular nucleus are found on the lateral floor and wall of the fourth ventricle in the pons and medulla.
Benign paroxysmal positional vertigo (BPPV) - This is the most common cause of vertigo in adults, but it is rarer in children. Unlike BPVC, BPPV is provoked by changes in the head position. [4] Otitis media and Vestibular neuritis - Unlike BPVC, these conditions are both associated with ear pain or fullness, and the vertigo is not episodic. [3]
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.
Occlusion of AICA is considered rare, but generally results in a lateral pontine syndrome, also known as AICA syndrome.The symptoms include sudden onset of vertigo, vomiting, nystagmus, dysarthria, falling to the side of the lesion (due to damage to vestibular nuclei), and a variety of same-side features including hemiataxia, loss of all types of sensation of the face (due to damage to the ...
The pyramidal tracts include both the corticobulbar tract and the corticospinal tract.These are aggregations of efferent nerve fibers from the upper motor neurons that travel from the cerebral cortex and terminate either in the brainstem (corticobulbar) or spinal cord (corticospinal) and are involved in the control of motor functions of the body.
