What is Dizziness?
Nearly 20% of adults will experience significant dizziness at some point in their lives. Vertigo and dizziness are the 2nd most common complaint after headache.
Dizziness can be described as a sensation of lightheadedness, floating, unsteadiness, giddiness or faintness. In contrast to dizziness, vertigo is described as a sensation of movement of either self or the environment moving around the person in a rotational or spinning manner.
Human vestibular system is extremely important in a person’s core functioning, affecting our ability to perform day-to-day tasks. The sense of equilibrium is sustained by a complex interaction of the subsequent parts of the nervous system:
- The inner ear – monitors directions of movement (side to side, up/down, forward/backward)
- Muscle and joint receptors – relay information about which part of the body is moving
- The eyes – monitor the position of the body in space
- Pressure sensors in our feet and spinal cord – tell the brain what body part is on the ground
- The central nervous system that includes the brain and spinal cord – help to sort out information relayed from the above four.
Causes of Dizziness
There are many possible origins of dizziness, however some of the most common are:
- Inner ear disease
- Migraine associated Vertigo
- BPPV – benign paroxysmal positional vertigo (this is also the most common cause of vertigo)
- Superior semicircular canal dehiscencence syndrome
- Traumatic brain injury
- Meniere’s disease
- Ototoxicity – poisoning by certain medications
- Acoustic Neuroma
- Mal de debarquement
Evaluation of a patient that complains of dizziness can often be challenging. However, with a directed history and an extensive evaluation, the cause of the patient’s symptoms can almost always be identified. The goal of the balance evaluation is to find the underlying cause and site of the problem, as well as to rule out life threatening disease.
