sever pain in the leg along the course of the sciatic nerve felt at the bas of the spine, down the thigh, and radiating down the leg due to a compressed nerve
sciatica
temp. loss of consciousness due to the sudden decline of blood flow to the brain; aka fainting
synacope
syncope due to a drop in blood pressure brought on by the response of the nervous system to abrupt emotional stress, pain, or trauma
vasovagal
recording of electrical activity in the brain, whose cells emit distinct patterns of rhythmic electrical impulses
electroencephalography (EEG)
