The Science Of Migraine What Happens In The Brain During An Attack

The Science Of Migraine What Happens In The Brain During An Attack The trigeminovascular system, which relays head pain signals to the brain, plays a key role in migraine pathophysiology and has components in the periphery (ie, outside the blood brain barrier) as well as in the central nervous system (cns) (ie, inside the blood brain barrier). 3,48 50. migraine may occur as a result of a dysfunctional. Premonition phase: a shift in mood or behavior could occur hours or days before the headache. aura phase: one third of people who have migraine headaches report an unusual “feeling” or aura before the headache. the aura phase is characterized by visual, sensory, or motor symptoms that appear just before the headache.

The trigeminal pathway. although it is clear from functional imaging studies that multiple brain regions involved in nociception are activated during a migraine attack (weiller et al., 1995; cao et al., 1999, 2002; bahra et al., 2001; afridi et al., 2005; denuelle et al., 2007), the site where the initial activation of these nociceptive pathways occurs has not been determined with certainty. One aspect of migraine pain theory explains that migraine pain happens due to waves of activity by groups of excitable brain cells. these trigger chemicals, such as serotonin, to narrow blood vessels. serotonin is a chemical necessary for communication between nerve cells. it can cause narrowing of blood vessels throughout the body. In the past, researchers thought of migraine as a blood vessel disorder, in part because some patients can feel a temple pulsation during a migraine attack. now, migraine is considered a sensory perceptual disorder, because so many of the sensory systems—light, sound, smell, hearing—are altered. during an attack, patients have concentration.
