Headaches
Five Fast Facts! (1) There are four types of dizziness, all of which become increasing common with increasing age:
Faintness, the feeling of being about to black out when upright. This can result from dehydration, abnormal heart rhythms, overmedication with blood pressure drugs and disorders of the autonomic nervous system. Loss of balance, feeling unsteady and about to fall even though muscle strength is normal. This can be caused by disorders of the inner ear; the cerebellum because of stroke or chronic alcoholism; or the basal ganglia, because of Parkinson's disease, for example. It can also result from overmedication with drugs like sedatives and anticonvulsants, vision disturbances and neuropathy or spinal cord disease that causes a loss of position sense in the legs. Vertigo, a false sense that the person or the surroundings are moving or spinning. This can result from motion sickness, Ménière's disease, middle-ear infections, migraines, multiple sclerosis, damage to the vestibular nerve and reduced blood flow to the brain after a stroke or transient ischemic attack. In the most common form, benign paroxysmal positional vertigo, sudden head movements cause a sensation of motion. Vague lightheadedness, a feeling of giddiness or detachment from the world that can be caused by a panic attack, depression, anxiety disorders or hyperventilation.
(2) Diagnosis
Diagnostic tests may include trying to reproduce the symptoms. For example, by rapidly standing and sitting, standing after lying down or lying on a tilt table while changes in blood pressure are measured. The doctor may test heart function with an electrocardiogram or an echocardiogram, an exercise stress test or a Holter monitor to detect abnormal rhythms. Vision tests may be performed, along with tests to evaluate balance and gait and C.T. or M.R.I. scans of the head, including noninvasive tests that check for narrowed or blocked arteries to the brain. If no physical explanation for dizziness is found, the patient may be checked for psychological disorders like depression, panic attacks or dissociation from the world (3) Treatment:
Treatment will depend on the cause of the dizziness. For example, for benign paroxysmal positional vertigo, a simple head-turning maneuver that repositions crystals in the inner ear may bring lasting relief. If ministrokes are the cause, the treatment may involve anticlotting drugs or opening a blocked artery with a stent. If medication is the problem, adjusting the dose or changing the drug can relieve dizziness. If dizziness persists despite treatment, lifestyle adjustments can help like avoiding sudden movements, keeping often-used items within easy reach, standing up slowly and clenching hands and flexing feet before standing. Physical therapy can help, as can exercises that strengthen muscles and that combine eye, head and body movements. (4) How to Massage for Headache Relief?
