Blocking substance P following a head injury can prevent tau protein tangles from forming in the brain and lower the risk for CTE and other head injury associated dementias.
Cognitive symptoms such as problems with memory and executive function, but not mood or motor disorders, were associated with CTE pathology. The findings advance the ability to diagnose CTE in living people. Until now, post mortem analysis was the only reliable method to detect CTE.
Longer career length and playing specific positions put NFL players at greater risk of developing cognitive problems and mental health issues. Playing for 10 or more seasons increased the risks for depression, anxiety, and cognitive impairment twice as much than those who played for a single season. For every five seasons of play, the risks increase 20% for cognitive impairment. Those most at risk are running backs, linebackers and those who played special teams positions.
Sustained hits following one season of playing football are enough to cause structural alterations to the brain. When players sustain a concussion, structural brain integrity decreases, and levels of tau increase. Researchers say, while concussions are a prime concern for those who play football, sustained hits also pose a threat to neurological health.
PET imaging of former NFL players who exhibited cognitive decline and psychiatric symptoms linked to CTE showed higher levels of tau in areas of the brain associated with the neurodegenerative disease.
Researchers say a single season of playing high school football is all it takes to cause microscopic alterations to the structure of the brain.
Researchers find evidence of cognitive issues and miRNA biomarkers, indicating brain injuries from concussions or head-to-head contact, in college football players. The findings indicated lasting damage caused by sports related concussions occur earlier than expected.
Researchers report activating microglia may help reduce the imbalance between neuroprotection and neurotoxicity for neurodegenerative diseases.
A new study, which involved a small sample of former professional athletes, found no evidence of early onset dementia.
A new study of football players who were diagnosed with CTE reveals those who started playing tackle football before the age of 12 had earlier onset of emotional and cognitive problems.
