Benign positional vertigo is a condition in which a person develops a sudden sensation of spinning, usually when moving the head. It is the most common cause of vertigo .
Vertigo - positional
Causes, incidence, and risk factors
Benign positional vertigo is due to a disturbance within the inner ear. The inner ear has fluid-filled tubes called semicircular canals. The canals are very sensitive to movement of the fluid, which occurs as you change position. The fluid movement allows your brain to interpret your body's position and maintain your balance.
Benign positional vertigo develops when a small piece of bone-like calcium breaks free and floats within the tube of the inner ear. This sends the brain confusing messages about your body's position.
There are no major risk factors. However, the condition may partly run in families. A prior head injury (even a slight bump to the head) or an inner ear infection called labyr...
Definition Vertigo is a sensation of motion or spinning that is often described as dizziness. Vertigo is not the same as light-headedness . People with vertigo feel as though they are actually spinning or moving, or that the world is spinning around them. Alternative Names Peripheral vertigo; Central vertigo Causes, incidence, and risk factors There are two types of vertigo: Peripheral vertigo occurs if there is a problem with the part of the inner ear that controls balance (vestibular labyrinth or semicircular canals) or with the vestibular nerve, which connects the inner ear to the brainstem. Central vertigo occurs if there is a problem in the brain, particularly in the brainstem or the back part of the brain (cerebellum). Vertigo related to the areas in the inner ear that control balance (vestibular labyrinth or semicircular canals) may be caused by: Benign positional vertigo (also called benign paroxysmal positional vertigo) Drugs such as aminoglycoside antibiotics, cisplatin, diuretics, or s...
Stress can wreck havoc on your health. And if you have asthma, you no doubt know that stress can cause asthma symptoms. The signs and symptoms of stress range from the benign to the dramatic – from simply feeling tired at the end of the day to having a heart attack. Researchers estimate that 75 percent to 90 percent of all visits to primary care physicians are for complaints and conditions that are, in some way, related to stress. And every week, approximately 112 million people take some form of medication for stress-related symptoms. Combine stress and asthma, and the result can be shortness of breath, panic attacks, a feeling of anxiousness, and a whole lot of worrying. In short, when stress rears its ugly head and you have asthma, you may trigger an asthma attack.“Asthma can be set off by stress, but I am not sure that anyone fully understands why,” says Dr. Marjorie L. Slankard, Clinical Professor of Medicine at Columbia University College of Ph...
