MRI neuroimaging can distinguish between memory loss caused by Alzheimer's disease and traumatic brain injury. Using new image analysis software, researchers discovered TBI causes the most amount of damage to the ventral diencephalon, a brain area associated with memory and learning, and the least amount of atrophy to the hippocampus, a brain region most impacted by Alzheimer's.
Former NFL players who received a concussion while playing are more likely to report low testosterone and erectile dysfunction. Researchers speculate the reason could be damage to the pituitary gland caused by concussion may spark a cascade of hormonal changes.
A new study identifies specific consumer products related to non-fatal brain injuries in children between the ages of 0 to 19. For infants, the leading cause of head injury is falling from beds, while in the teenage group, sporting equipment was the leading cause of TBI.
Many survivors of domestic violence are likely to have experienced repeated head injuries and oxygen deprivation. The injuries resulted in memory loss, anxiety, and visual problems. Of the 49 people interviewed for this study, 81% report being hit in the head by their partner, while 83% report strangulation events.
Neuroimaging helps researchers observe what happens in the brain as a person is rotated. The study, which gives insight into how the brain moves after the head stops moving, also provides critical information for advancing studies of TBI.
Disruptions in the supply of allopregnanolone, a hormone created by the placenta late in pregnancy, to the developing fetus can leave children more vulnerable to brain injuries associated with ASD. Losing the supply of ALLO alters cerebellar development, an area of the brain critical for motor coordination and social cognition, impacting the post-birth development of cerebellar white matter. An experimental model revealed deficient cerebellar white matter resulted in social impairments and an increase in repetitive behaviors, two hallmark features associated with autism.
A number of patients in intensive care units for non-brain-related illnesses may suffer from cognitive dysfunction. Inflammation that occurs as a result of infection and problems with oxygen flow to the brain which occur when breathing is affected, could contribute to cognitive impairments.
Animal-assisted therapy improves social behaviors and reduces negative emotions in those with TBI. The findings report those with brain injuries exposed to AAT experienced higher social engagement, satisfaction and motivation following therapy sessions.
Retinal ganglion cell survival following a stroke depends on whether the pathway to the primary visual area remains active. Cells connected to inactive areas of the visual cortex suffer atrophy and degenerate, leading to permanent visual impairment.
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.
