By modifying a key gene in very early-stage embryos, the researchers demonstrated that a gene plays a…

Caregivers should be screened early, often to prevent depression, anxiety

Science Currently, more than 34 million people in the U.S. care for terminally ill love ones, but few resources are available to help them navigate the challenges they encounter. A study has found that nearly one-quarter of caregivers were moderately or severely depressed and nearly one-third had moderate or severe anxiety. The researchers recommend that health providers remember to treat the whole family, providing ongoing screening to family caregivers to identify early signs of depression and anxiety. Caregivers should be screened early, often to prevent depression, anxiety
