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]
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]
Hemiballismus or hemiballism is a basal ganglia syndrome resulting from damage to the subthalamic nucleus in the basal ganglia. [1] It is a rare hyperkinetic movement disorder, [2] that is characterized by pronounced involuntary limb movements [1] [3] on one side of the body [4] and can cause significant disability. [5]
The DizzyFIX is a home medical device designed to assist in the treatment of benign paroxysmal positional vertigo (BPPV) and its associated vertigo. [1] The device is a head-worn representation of semi-circular canals. The device is filled with fluid and a particle representing the otoconia (loose hard particles) associated with BPPV.
Lizard tail autotomy can distract predators, continuing to writhe while the lizard makes its escape. Some animals are capable of autotomy (self-amputation), shedding one of their own appendages in a last-ditch attempt to elude a predator's grasp or to distract the predator and thereby allow escape. The lost body part may be regenerated later.
Since bubbles can form in or migrate to any part of the body, DCS can produce many symptoms, and its effects may vary from joint pain and rashes to paralysis and death. DCS often causes air bubbles to settle in major joints like knees or elbows, causing individuals to bend over in excruciating pain, hence its common name, the bends.
