Patients often stress and worry about an upcoming surgery. But stress can lessen your body’s ability to heal. It can increase inflammation—the swelling or heat your body makes to protect against injury or illness. You can take steps to improve your health before surgery. This is called prehabilitation. A new study showed that personalized prehabilitation programs lowered problems after surgery.…

Arsenic is a naturally occurring element. It’s found in soil, water, and air. Long-term exposure can cause health problems. Millions of people rely on water sources with unsafe levels of arsenic. A new study showed that reducing arsenic exposure can lower the chances of death from cancer and heart disease. The study tracked adults living in Bangladesh. Researchers measured the levels of arsenic…

Cancer cells multiply in an uncontrolled way, making them difficult for your body to stop. Chemotherapy, or chemo for short, uses drugs to kill cancer cells or stop them from growing. These drugs usually target cells that are growing quickly. Normal body cells can also get caught in the crossfire of many chemotherapy drugs, causing unwanted side effects. Scientists are finding ways to lessen…

Your brain contains a complex network of nerve cells, called neurons, that send signals to the rest of your body. These signals allow you to sense the world around you, control your body’s movements, and experience emotions. But sometimes things can go wrong. Groups of neurons may send abnormal bursts of signals all at once. This surge of brain activity is called a seizure. Any seizure is a cause…, Unraveling Symptoms, Anything that disturbs the pattern of normal brain activity can lead to seizures.

You may have [qtip:neurological|Related to the body’s nervous system, which is made up of the brain, spinal cord, and nerves throughout the body.] testing and blood tests done. Blood tests can check for infections or genetic conditions.…, Dr. Carrie McDonald, a scientist who specializes in imaging at the University of California, San Diego, is testing artificial intelligence (AI) to identify these brain patterns on MRI scans. Her group found that AI could correctly identify over 80% of individuals with temporal lobe epilepsy. “Using AI to identify brain areas with specific patterns of damage will not only help radiologists but…, Getting Treatment, Doctors usually prescribe antiseizure drugs first to control seizures. But some people don’t respond to these drugs. They may need to see a nervous system specialist, called a neurologist, who focuses on epilepsy. Dr. Sara Inati, an epilepsy specialist at NIH, is researching better ways to evaluate and treat people with drug-resistant epilepsy. They may have repeated seizures that can damage…
