The mismatch between the information coming from the ear that is malfunctioning and the remaining normal senses can cause disturbance in balance and eye movement and nausea/vomiting. If the inner ear is working abnormally either sending too few signals or too many signals, a disturbance can occur causing the patient to feel dizziness. Even at rest, the inner ear on each side sends signals to the brain. In addition, the information allows patients to maintain a sense of orientation in space. This allows a person to keep their balance and to allow them to keep their eyes on a target whilst moving their head. Using this information the brain can control the movements of the eyes and body. This information is sent from each inner ear to the brain and integrated with information from the eyes and proprioception (sensation from joints and skin) to provide sensory information for the brain. The inner ear is involved in the detection of movement and gravity. Signals from these senses also provide a person with a sense of orientation in space. The signals from the inner ear and vision help control eye movements allowing a person to keep their vision on a target while their head is moving. The brain integrates the signals from these 3 senses and sends signals to the muscles to control body movement and eye movement.
#MIGRAINE HEARING HEARTBEAT IN EAR SKIN#
The sensations involved in balance include the inner ear, vision and proprioception (signals from joints (particularly the ankle and neck) and skin(particularly skin of the feet)).
To allow a person to maintain their balance a number of sensory structures/systems must be intact and working correctly. In a number of cases, the exact cause of dizziness cannot be determined with certainty. In other cases, specific treatments may be required. In some cases, particularly if the problem is improving nothing but reassurance is required. The appropriate management/treatment can then be instituted. In order to determine if the problem is serious, doctors will assess patients using a combination of history taking (the story of the dizziness), examination and if required special investigations/tests. Some types of dizziness/light headiness can be due to more serious problems such as an irregular heartbeat or low blood pressure. Dizziness/imbalance, particularly those due to inner ear problems, usually do eventually resolve spontaneously. In some cases, however, the problem can be longer-lasting and disabling. Again these tend not to be caused by inner ear balance system disorder.įor many patients, the dizziness is short-lasting and the patient does not seek any medical attention. Other types of descriptions may include: “spaced out feeling” or “out of body experience”. Irregular heartbeat or low blood pressure can cause this. Generally, this is not due to inner ear problems.
This can progress to loss of consciousness. Light-headedness or fainting: This is a sensation one experiences if their blood pressure drops.The causes of this are more varied but can include inner ear problems, problems with the balance part of the brain, abnormal sensation in the feet/ankle/legs, muscle weakness and age-related changes (or a combination of problems).
Patients use many different words such as dizziness, giddiness, unsteadiness, imbalance, spinning, light-headedness etc. The experience of dizziness can be difficult to describe. Dizziness: Vertigo Unsteadiness Lightheadednessĭizziness is a common problem.
