Fear of public places is common in adults with epilepsy

A recent study found that phobic and agoraphobic symptoms are prevalent in adults with epilepsy, affecting their quality of life. The research, led by Dr. Heidi Munger Clary, analyzed a diverse sample of 420 adults with epilepsy and discovered that more than one-third reported significant phobic/agoraphobic symptoms.

Children’s immune response to coronavirus: fast but doesn’t last

New research reveals that children's immune systems have a strong initial reaction to coronavirus but don't develop long-lasting memory T cells like adults do. This means they are at risk of getting sick when reinfected and may experience an immune over-reaction, leading to severe symptoms.
