describe EPILEPSY
CNS disorder where the neural cells' activity is disrupted; characterized by seizures, repeated twitching of limbs, & occasional loss of consciousness
describe POSTPARTUM PSYCHOSIS
rare condition within the 1st week after birth w/ confusion, disorientation, hallucinations, delusions, obsessive thoughts about baby, paranoia, sleep...
describe FUNCTIONAL MRI (fMRI)
detects changes in blood flow in brain; pictures relevant brain tissue when accomplishing task

ultrasound study of carotid artery to detect plaque buildup or predict/diagnose ischemic stroke
define ELECTROENCEPHALOGRAPHY (EEG)
record electrical brain activity via electrodes & displayed as waves to diagnose conditions affecting brain function & consciousness
describe MYELOGRAPHY
fluoroscopic & CT study of cord w/contrast via lumbar puncture; done only if MRI of spine not good enough
