  • Vertiginous epilepsy

    serch.it?q=Vertiginous-epilepsy

    Vertiginous epilepsy is infrequently the first symptom of a seizure, characterized by a feeling of vertigo. When it occurs there is a sensation of rotation or movement that lasts for a few seconds before full seizure activity. While the specific causes of this disease are speculative there are several methods for diagnosis, the most important being the patient's recall of episodes. Most times, those diagnosed with vertiginous seizures are left to self-manage their symptoms or are able to use anti-epileptic medication to dampen the severity of their symptoms. Vertiginous epilepsy has also been referred to as Epileptic vertigo, Vestibular epilepsy, Vestibular seizures, and Vestibulogenic seizures in different cases, but vertiginous epilepsy is the preferred term.

  • Orthostatic intolerance

    serch.it?q=Orthostatic-intolerance

    Orthostatic intolerance (OI) is the development of symptoms when standing upright which are relieved when reclining. There are many types of orthostatic intolerance. OI can be a subcategory of dysautonomia, a disorder of the autonomic nervous system occurring when an individual stands up. There is a substantial overlap between syndromes of orthostatic intolerance on the one hand, and either chronic fatigue syndrome (CFS) or fibromyalgia (FM) on the other. It affects more women than men (female-to-male ratio is at least 4:1), usually under the age of 35. Orthostatic intolerance occurs in humans because standing upright is a fundamental stressor and requires rapid and effective circulatory and neurologic compensations to maintain blood pressure, cerebral blood flow, and consciousness. When a human stands, approximately 750 mL of thoracic blood is abruptly translocated downward. People who suffer from OI lack the basic mechanisms to compensate for this deficit.

  • Dizziness

    serch.it?q=Dizziness

    Dizziness is an impairment in spatial perception and stability. The term dizziness is imprecise: it can refer to vertigo, presyncope, disequilibrium, or a non-specific feeling such as giddiness or foolishness. One can induce dizziness by engaging in disorientating activities such as spinning. Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find vertigo very disturbing and often report associated nausea and vomiting. It represents about 25% of cases of occurrences of dizziness. Disequilibrium is the sensation of being off balance and is most often characterized by frequent falls in a specific direction. This condition is not often associated with nausea or vomiting. Presyncope is lightheadedness, muscular weakness, and feeling faint as opposed to a syncope, which is actually fainting. Non-specific dizziness is often psychiatric in origin. It is a diagnosis of exclusion and can sometimes be brought about by hyperventilation.A stroke is the cause of isolated dizziness in 0.7% of people who present to the emergency department.
