If fainting spells occur often without a triggering event, syncope may be a sign of an underlying heart disease. [37] In the case where syncope is caused by cardiac disease, the treatment is much more sophisticated than that of vasovagal syncope and may involve pacemakers and implantable cardioverter-defibrillators depending on the precise ...
Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger. Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...
Throughout the 20th century the dominant model [2] for language processing in the brain was the Geschwind–Lichteim–Wernicke model, which is based primarily on the analysis of brain-damaged patients. However, due to improvements in intra-cortical electrophysiological recordings of monkey and human brains, as well non-invasive techniques such ...
Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in developed countries. [3]
Since one of the focuses of this field is the testing of linguistic and psycholinguistic models, the technology used for experiments is highly relevant to the study of neurolinguistics. Modern brain imaging techniques have contributed greatly to a growing understanding of the anatomical organization of linguistic functions.
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
In 2019, Karina Drury was diagnosed with postural orthostatic tachycardia syndrome, POTS
The medical term for fainting, or ataques de nervios, is syncope, which happens when the brain does not receive enough oxygen and there is a brief decrease of blood flowing to the brain. Situational syncope occurs when situations affect the nervous system, such as anxiety, fear, pain, dehydration, hyperventilation, and the use of alcohol or ...
