...while others who have never had a seizure will show abnormalities. It's unclear when to perform the test, though most studies suggest that the best chance of spotting abnormalities is in the first 24 hours. If a serious underlying brain disorder is suspected, doctors may also recommend an MRI scan (which is now preferred over C.T. scans), but these tests won't tell you much about epilepsy...
GLOWING GRAY MATTER Having the Alzheimer's gene takes its toll--even when the memory is still intact. A special MRI shows that asymptomatic folks who are at genetic risk for Alzheimer's work harder to answer easy mental tests than other people. How can doctors tell? On the MRI, the area of the brain responsible for thinking lights up more than other areas. The tool may one day be used as a kind of mental stress test to detect Alzheimer's earlier, much as a treadmill tests for heart disease today...
...stroke. Even for specialists this can be a tricky business, as there are two major groups of strokes and each requires different tests and treatments. In a hemorrhagic stroke, a blood vessel bursts and causes bleeding in the brain, which can be detected immediately by a C.T. or MRI scan. In the other, major family of strokes, ischemic, a clot obstructs the flow of blood, starving and killing brain tissue beyond the blockage. This kind of stroke, which Ford suffered in the balance center at the base of the brain, may also be seen by C.T. or MRI, but sometimes...
Officially, Coelho resigned for health reasons, and his maladies are real. He suffers from epileptic seizures, and checked into a Virginia hospital last week because of diverticulitis, an inflamed colon. Also, Coelho told a friend that an MRI had revealed a cyst on his brain, which may be the reason he has been suffering more frequent seizures. Tipper Gore and campaign manager Donna Brazille visited him last Tuesday; the next day, when Brazille called, Coelho told her, "It's not good...
ATTENTION! Using a special MRI technique, researchers have mapped out regions of the brain involved in paying attention. The frontal cortex and parietal cortex--in the front and back of the brain, respectively--appear to light up when subjects focus on certain signals. Then, as the new stimuli are processed, the visual cortex in the lower rear of the brain moves into action. The finding may help researchers better understand attention-deficit/hyperactivity disorder and even schizophrenia...
