What is otolith disease?
Abstract. Benign paroxysmal positional vertigo (BPPV) (otolith disease) is the most common neurological and position change related vertigo, accounting for 17–20% of peripheral vertigo. BPPV occur in the elderly. The high incidence age for BPPC was 50 to 70 years and mostly in female.
Is hyperlipidemia a circulatory disorder?
Hyperlipidemia is a common metabolic disorder and one of risk factors for cardiovascular disease. Clinical studies have shown that hyperlipidemia increases the risk of non-ischemic heart failure, while decreasing serum lipids can reverse heart dysfunction.
Why is hypercholesterolemia a risk factor for atherosclerosis?
Hypercholesterolemia is an acknowledged risk factor for atherosclerosis. It is associated with abnormal endothelium-dependent vasodilation and decreased NO bioavailability in both animal and human studies, independent of the presence of atherosclerosis (41).
What is the pathophysiology of BPPV?
BPPV occurs when tiny calcium crystals called otoconia come loose from their normal location on the utricle, a sensory organ in the inner ear. If the crystals become detached, they can flow freely in the fluid-filled spaces of the inner ear, including the semicircular canals (SCC) that sense the rotation of the head.
What is the importance of otolith?
Otoliths in bony fishes play an important role in the senses of balance and hearing. Otolith mass and shape are, among others, likely to be decisive factors influencing otolith motion and thus ear functioning.
What does the cupula do?
The ampullary cupula, or cupula, is a structure in the vestibular system, providing the sense of spatial orientation.
Is hyperlipidemia the same as hypercholesterolemia?
Hyperlipidemia means your blood has too many lipids (or fats), such as cholesterol and triglycerides. One type of hyperlipidemia, hypercholesterolemia, means you have too much non-HDL cholesterol and LDL (bad) cholesterol in your blood.
How does hyperlipidemia cause cardiovascular disease?
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
How does hypercholesterolemia cause heart failure?
How does cholesterol contribute to cardiovascular disease?
How Does High Cholesterol Cause Heart Disease? When there is too much cholesterol in your blood, it builds up in the walls of your arteries, causing a process called atherosclerosis, a form of heart disease. The arteries become narrowed and blood flow to the heart muscle is slowed down or blocked.
Is BPPV a neurological disorder?
Unlike some other causes of vertigo, BPPV doesn’t cause nervous system symptoms such as severe headache, speech problems, or loss of limb movement. It also doesn’t cause hearing problems. The symptoms of BPPV may seem like those of other health conditions.
What is the most common cause of BPPV?
When there is a known cause, BPPV is often associated with a minor to severe blow to your head. Less common causes of BPPV include disorders that damage your inner ear or, rarely, damage that occurs during ear surgery or long periods positioned on your back, such as in a dentist chair.
What is otolithic disorder?
Otolithic Disorders refers to damage of the otolith organs, saccule and utricle that sense linear acceleration in the vertical and horizontal planes. हिंदी में पढ़ें.
Can we measure the damage to the otolith organs?
Patients suffering from the disease often complain about the feeling of chronic unsteadiness, rocking or floating. However, until recently, there was no method of measuring the damage to the otolith organs.
What are the tests used to diagnose otolith disorders?
The cervical ( c-VEMP) and ocular (o-VEMP) have been used to test the function of the utricle and saccule. Otolith disorders are treated by long term vestibular rehabilitation aimed at otolith stimulation. Dr.Anita Bhandari is MS (ENT) and a consultant Neurotologist practising in Jaipur, India.
What happens if the otoliths of the eye are damaged?
Any damage to the otoliths or their central connections impairs the body’s equilibrium and visual stability. Patients suffering from the disease often complain about the feeling of chronic unsteadiness, rocking or floating.
