Overview
Dizziness is a complex and subjective complaint that encompasses a wide spectrum of symptomatology.It is a sensation of postural unsteadiness or deceptive motion. It is one of the most communal presenting complaints that accounts for 5% of primary care practice for individuals aged 65 or older. Dizziness is a nonspecific term mainly used by many people and is classified into different categories: vertigo, spinning, disequilibrium, giddiness, presyncope, faintness, lightheadedness, or feeling woozy.[1] It is one of the most common presenting symptom among patients seen by emergency medical physicians, primary care physicians, neurologists, and otolaryngologists.[1]
Classification
Dizziness may be classified based on the symptoms of the patient into 4 main subtypes including vertigo, presyncope, [[BPPV], and disequilibrium.
Pathophysiology
It is understood that pathophysiology of dizziness depends on the etiological subtype including orthostatic hypotension, benign paroxysmal positional vertigo, Menier's disease, Parkinson's disease, hyperventilation syndrome, peripheral neuropathy, and vestibular migraine.
Causes
Dizziness may be caused by hypotension, dehydration, arrhythmia, labyrinthitis, Meniere's disease, stroke, or hypoglycemia. Other causes are based on the organ system such as cardiovascular, neurological, musculoskeletal, dermatological, endocrine, infectious, pulmonological or side effects of the medicine.
Differentiating dizziness from other diseases
Dizziness must be differentiated from other diseases that cause vertigo, nystagmus, and hearing problems, such as vestibular neuritis, HSV oticus, Meniere disease, labyrinrhine concussion, perilymphatic fistula, semicircular canal dehiscence syndrome, vestibular paroxysmia, Cogan syndrome, vestibular schwannoma, otitis media, aminoglycoside toxicity, recurrent vestibulopathy, vestibular migraine, epileptic vertigo, multiple sclerosis, brain tumors, cerebellar infarction/hemorrhage, brain stem ischemia, [[Arnold-Chiari malformation|chiari malformation], presyncope and disequilibrium.
