A new model of chronic dizziness: EXERTIONAL DIZZINESS and Dizziness Threshold.
representsthe majority of chronic dizziness, including psychogenic and psychophysiologic dizziness.
2)Presyncopewith feelings of passing out due to hypoperfusion of oxygen or sugar to brain from sudden low blood pressure from slow autonomic nervous system response ( orthostatic hypotension, cough or micturition syncope, etc ), or cardiac response ( heart failure, aortic valve stenosis, brady or tachyarrthymias ), or metabolic disturbances including hypoglycemia.
3)Vertigowith sensations of spinning inside the head or of the surroundings due to inner ear disorders ( The favorite diagnoses for dizziness includingBenign positional vertigo, Menieres disease, vestibular neuonitis,the top 3's, and central vertigo from accoustic neuroma or cerebrovascular ischemia or stroke). Dizziness is not the same as vertigo. Vertigo is only one subcategory of dizziness, and is not even the most common subcategory of dizziness. Terms Dizziness and Vertigo should not be used interchangibly.
4)Dyseqilibriumwith unsteadiness. from drugs, cerebellar disorder, or neuropathy with muscular weakness.
Significant Dizziness is found in 18 % of adults and 30 % of elderlies, roughly. But the majority of chronic dizziness belong to category 1) lightheadedness, vaguely described
more as wooziness and sometimes as spinning sensations inside one's head and usually not accompanied by other clear symptoms and signs. The major signs which clinicians always look for when confronted with a dizzy person are a) signs of presyncope: hypotension, orthostatic hypotension, cardiac abnormalities,or abnormal autonomic nervous system, b) vertigos from vestibular dysfunctions with nystagmus, hearing losses, or neurological deficits ,and c) dysequilibrium with gait ataxia or sensory neuropathy. However, these signs are missing more often than not, but because of frequent mentioning of mild spinning in the head, the diagnosis of benign paroxysmal positional vertigo ( BPPV ) is given despite the absence of nystagmus, and is the 2nd commonest etiology of dizziness, behind psychosomatic dizziness. If the criterion of nystagmus is strictly adhered to, then BPPV is not a common clinically important cause of dizziness at all. Even if BPPV is loosely attributed to be the cause of dizziness, still in 40 % of all chronic dizziness, Psychogenic make up is deemed to be the major etiology. At any rate, Antivert is the drug mostly prescribed despite ineffectiveness except in cases of genuine inner ear dysfuntion. If the criterion of nystagmus is strictly adhered to, then BPPV is not a common clinically important cause of dizziness. In short,most chronic dizziness belong to 1) light headedness/ wooziness with occasional spinning in the head, and no full biomedical explanation and drugs are available.
According to chinese herbal medicine, dizziness occurs 1) when the brain is malnourished( from qi,blood, yin, or yang deficiency ), 2) whenpathogenetic factors block the nourishments from reaching the brain( mental phlegms, blood stasis, uprising liver yang or heat ) or finally,3) bya combination of 2 above mechanismsof deficiency and excess. Biomedically translated, chronic dizziness is a symptom of chronic, recurrent and relativelytransient insufficency of oxygen and sugar to all parts of brain including the brainstem and inner ear, caused by evolutionarily IMPERFECT AUTOREGULATION OF CEREBRAL BLOOD FLOW, EITHER FUNTIONAL OR DUE TO ARTERIOSCLEROSIS, in response to surge of demandswhich is not demonstrable by MRI or MRA or lab measurements. Chronic dizziness is analogous to chronic exertional angina caused by insufficient blood flow to the heart muscles, when the demand for oxygen is increased above the threshold of compromised coronary circulation, as with excess exercise or emotional outbursts. Thismodel of demand and supply of brainexplains well why most oftendizziness flares up after strenuous mental exertionrequiring lots of oxygen and sugar. This also is why to control chronic dizziness, one needs to reduce the demands by mentally resting, whileherbal remedies work on the supply sideby 1)nourishing the brain with Qi and Blood, 2) getting rid of pathogenetic factors blocking the supply, and thereby improving the responsiveness of autoregulation of cerebral blood flow. In most chronic dizziness, one feels fine in AM after a goog night sleep, and dizziness appears after EXERTION ,especially mental, and one can even guess when dizziness will appear ( like reading a complex book for 2 hours). There is a Dizziness THRESHOLD for most chronically dizzy people, and our herbal formulas will elevate this threshold over time ( one may read on theories of mathematics for 4 hours instead of 2 hours before the onset of dizziness).
Dizziness is a commonsymptom for which biomedicine has little to offer except meclizzine( antivert)which is mildly effective for vertigo, butdoes not get to " the roots" of dizziness, which took decades to develop. OUR HERBAL REMEDIES CAN BE MORE EFFECTIVE,but for chronic dizziness, one is better taking the right formula(s) for a long term to heal or manage the root syndrome causing the particular dizziness. We can testify to our Korean elderlies whose chronic dizziness with spinnings and easy falls are well controlled with usage of our formulas.
ASimplified Guidefor choosing the appropriate formula for your kind of dizziness.The best herbal remedyforacute or flare of dizzinessisDIZZY/VERTIGO( Itcured our chihuahua's vertigo with severe nystagmus. Take 6 capsules 2 to 3 times daily for 1 to 2 weeks or chronically as necesary).
Chronic mild dizziness often has the same roots as chronic fatigueaccording to chinese herbal medicine. If one's fatigue is the major symptom, and dizziness is only a minor symptom ( Dizziness, nevertheless, alarms people much more, while many in American culture tend to resign easily to chronic moderate fatigue ), then one may take our formula for chronic fatigue for mild chronic dizziness, i.e. Fatigue & Blurry is an excellent formula for the middle aged with much fatigue and mild dizziness.
