Experiencing three or more concussions is linked with worsened brain function in later life, according to major new research. The study – the largest of its kind - also found having just one moderate-to-severe concussion, or traumatic brain injury (TBI), can have a long-term impact on brain function, including memory.
A new study published in Neurology dispels the notion that "mild" concussions have no lasting impact on mental skills like thinking, remembering, and learning. Poor cognitive outcomes are common 1 year after injury.
Is concussion and/or mild traumatic brain injury (TBI) associated with a higher risk of suicide? This systematic review and meta-analysis found a 2-fold higher risk of subsequent suicide among more than 700 000 patients diagnosed with concussion and/or mild TBI, compared with more than 6.2 million individuals who had not been so diagnosed. Experiencing concussion and/or mild TBI was also associated with a higher risk of suicide attempt and suicidal ideation. These results suggest that experiencing concussion and/or mild TBI is associated with an increased risk of suicide.
A University of Washington study finds 81% of sexual assault survivors experience significant PTSD-related symptoms just one week after the attack, 75% after a month, 53% after three months. After a full year, 41% percent met the criteria for PTSD diagnosis. Study authors discovered that many started feeling better within three months.
Light-induced pain or discomfort, or ‘photalgia’ (otherwise known as light sensitivity, photophobia, asthenopia, photoallodynia or photodynia) is a well-known consequence of mild traumatic brain injury.
A study comparing depression rates in men and women one year after moderate or severe TBI shows no significant gender differences in depression symptom levels. But researchers did find different patterns of other symptoms.
