Causes of Dizziness
There are different causes behind the disease dizziness. The function of our balance organ depends on many health factors in the body. The information needed for the brain to control balance comes from the three senses: hearing (ears), sight (eyes), and touch and depth. The brain converts the information in such a way that all movements in the body are coordinated and our usual movements take place. The necessary movement sequences are saved. In order for everything to function smoothly, the areas responsible for our balance and the brain must be sufficiently supplied with nutrients and oxygen. An intact blood flow is just as important as a functioning blood pressure. If disturbances or obstacles occur, various types of dizziness occur.
The brain gives us an indication that our equilibrium system is disturbed. The vestibular system is irritated by harmless stimuli, but certain diseases, for example in the inner ear, can also affect the balance function. The reason for this is the position of the balance organ, which is located in the inner ear. Disorders in the balance center of the brain, vascular problems, cardiovascular disorders, nerve inflammation, mental illness or metabolic diseases also lead to dizziness. Another possible cause is the natural signs of aging.
The most common type of vertigo is benign positional vertigo. The seizures occur due to changes in the position of the head. The reason for the dizziness can be ear stones, which are deposited in the posterior semicircular canals of the inner ear. The stones can be caused by wear and tear from a head trauma or vestibular neuritis (failure of the balance organ on one side).
In the case of bilateral vestibulopathy, the vestibular system on both sides and parts of the vestibular nerves are dysfunctional. The cause of the failure is usually unknown. For example, inflammation in the brain, such as meningitis, can be related, but also Meniere’s disease, a rare disease of the inner ear. The inner ear may also have been attacked by antibiotics (aminoglycosides) that are rarely used, which can disturb the sense of balance. Canvas syndrome also behaves suspiciously, which can cause bilateral vestibulopathy with staggering and vertigo as well as changes in the brain with coordination disorders.
Other possible causes of dizziness are: alcohol, an inner ear or middle ear infection, a tumor on the vestibular nerve, vertigo migraines (vestibular migraines), vascular changes, vertebrobasilar insufficiency (circulatory disorders in the inner ear and brain), an occlusion of the clavicle artery or a stroke. However, a drop in blood pressure when the body is upright (orthostatic hypotension), Parkinson’s disease, an injury to the base of the skull, damage to the cervical spine or high or low blood sugar in diabetics can also cause dizziness.
