5. The prior treatment for migraines included medicine that
-
A. eliminated any pain.
-
B. tightened blood vessels.
-
C. eliminated the aura.
-
D. eliminated stress.
Correct Answer
A. B. tightened blood vessels.Explanation
The prior treatment for migraines included medicine that tightened blood vessels. This suggests that the medication used in the past aimed to constrict the blood vessels in order to reduce the severity of migraines. Tightening blood vessels can help alleviate migraines as it reduces the blood flow to the brain, which is believed to be a contributing factor to migraines.Rate this question:

This magnetic field can induce electrical currents in the neurons, leading to their activation or inhibition. TMS is used in neuroscience research to study brain function, as well as in clinical settings to treat certain neurological and psychiatric disorders.Rate this question:
