Dizziness is a physical sensation that most people have experienced before. In the process, those affected feel that their surroundings are spinning or they feel unsteady on their feet, forcing them to interrupt their previous activity.
Dizziness can take a certain direction ( eg rotation and Schwankschwindel ), but also be undirected, ie the affected feels a tumble.
In case of dizziness there is an additional feeling of dizziness ( eg weak knees, etc. ), concentration is difficult or drowsiness occurs.
The following text focuses on dizziness combined with dizziness.
If the dizziness manifests itself with additional dizziness, a distinction should be made between a frenzy and a trend-setting dizziness. If one speaks of a directional dizziness, one means a fluctuating or rotating feeling, that is, a describable direction. Taumel is more of an uncertainty or lack of feeling that you are not able to describe a direction.
In a directed dizziness are more likely to disturbances of the sense of balance and the involved nerves in question. There are various possibilities, ranging from a position-dependent dizziness ( sticking of direction-indicating crystals in the organ of equilibrium ) via an inflammation of the nerves to an infarct in the corresponding area.
With undirected dizziness both internal and neurological diseases as well as overdoses of drugs or stimulants are considered. Especially with a simultaneous dizziness is the suspicion of cardiovascular abnormalities ( eg too low blood pressure shortly after getting up ) or metabolic imbalances ( eg high / low blood sugar ) close.
Certain classes of medication ( eg water-secreting drugs, antihypertensive agents, insulin, various heart medicines ) tend to overdose or overdose to this combination of symptoms.
Stroke or cerebral hemorrhage may play a role in neurological disorders, both of which can cause dizziness.
Dizziness with concomitant drowsiness may also be due to motion sickness, defective vision or movement disorders of the eyes, a cervical syndrome, or changes in older age, or may occur during hyperventilation.
Muscular or bony changes reduce mobility and the ability to relay information about the location of the head. This can cause dizziness or a feeling of drowsiness in those affected.
Fatigue or drowsiness with dizziness is common in motion sickness. The motion sickness is triggered by unusual movements, such as on a staggering ship. Contradictory information about the sense of balance causes nausea, dizziness and fatigue.
It may also be accompanied by other symptoms such as cold sweat, paleness or headache. Just as well, fatigue during a dizziness can be caused by low blood pressure or anemia ( red blood cell poverty ).
In psychologically stressful conditions such as depression or anxiety, dizziness and tiredness may occur, as well as other symptoms.
Dizziness often causes nausea or even vomiting. This is mostly due to the brainstem located in the brain stem, which is connected to many other areas of the brain. If the brain does not get matching information about the movement of the body and the immediate environment, it often causes nausea.
At the same time as dizziness, headaches or a feeling of pressure in the head can also occur. The headache can occur unilaterally as in a migraine and still be associated with photosensitivity. If the headache occurs at the back of the head, this may be a sign of a cervical spine syndrome.
It is not uncommon to experience visual disturbances of any kind ( eg double vision, blurred vision, restriction of the field of vision ) during dizziness. The information of the eye contributes to a large extent to the sense of balance of the person. Therefore, a vision disorder may be the trigger of the dizziness or a symptom that may have the same cause as dizziness.
A detailed history of the dizziness in terms of the time of onset, duration, dizziness, and other concomitant symptoms may already reveal the root cause or at least narrow the range of possible causes. Also, the question of existing pre-existing conditions and currently taken medication helps in this case on.
Internal and neurological diseases are excluded by various studies as a trigger for dizziness. This often includes a blood pressure measurement, the collection of blood sugar or an ECG as well as an orienting neurological examination with examination of the reflexes, coordination or sensory perception abilities. The so-called nystagmus test can also be enlightening here. An abnormal eye movement is checked.
If these tests are not sufficient to determine the cause of dizziness, further options are available. For example, a computed tomography of the head, an ultrasound of cerebral vessels, measurement of nerve conduction velocity or long-term ECG / blood pressure measurement.
Since undirected dizziness and parallel dizziness can lead to various causes (see above), therapy must be closely geared to the triggering factors. Here, drug adjustments and a stabilization of the circulatory and metabolic situation are in the foreground.
With age-related dizziness, gait training or balance training can be beneficial. If a cervical spondylosis is the suspected trigger, physical therapy may be effective.
