Adults who voluntarily take part in mindfulness courses are less likely to experience symptoms of anxiety and depression for at least six months after completing the programs, compared to adults who do not take part, a new analysis pooling data from 13 studies has confirmed.
Jul 5, 2023 - A new study suggests that depression after traumatic brain injury (TBI) could be a clinically distinct disorder rather than traditional major depressive disorder, with implications for patient treatment.
Jul 5, 2023 - New research has found that the way childhood abuse and/or neglect is remembered and processed has a greater impact on later mental health than the experience itself. The authors suggest that, even in the absence of documented evidence, clinicians can use patients' self-reported experiences of abuse and neglect to identify those at risk of ...
Jun 27, 2023 - Major depressive disorder (MDD) is not only among the most common mental illnesses, affecting over 8% of Americans, but it is also extremely variable from one person to another.
