abdominal aura

abdominal aura
   Also known as visceral aura and epigastric aura. The term abdominal aura is indebted to the Latin words abdomen (belly) and aura (wind, smell). It is used to denote a type of * somatosensory or *somaesthetic aura that typically manifests itself as a rising epigastric sensation. Other presentations of the abdominal aura include viscerosen-sitive sensations such as abdominal discomfort, visceromotor symptoms presenting in the form of tachycardia, borborygmi or vomiting, and vegetative symptoms such as blushing and sweating. Pathophysiologically, the abdominal aura is associated with aberrant neuronal discharges in sensory cortical areas representing the abdominal viscera. Etiologically, it is associated primarily with paroxysmal neurological disorders such as migraine and epilepsy. The abdominal aura can be classified as a * somatic or *coenesthetic hallucination. The term is used in opposition to various terms denoting other types of somatosensory aura, notably * splitting of the body image and * paraesthesia.
