Concerns about traumatic brain injuries to US troops have resurfaced amid the Iran war. A former Marine, Joe Shearer, experienced blasts from an enemy mortar round and a roadside bomb while fighting in Iraq. These incidents, which occurred in 2005, have been linked to traumatic brain injuries that were only recently diagnosed.

Shearer, now 40, continues to suffer from symptoms such as dizziness and migraines. Further details about Shearer's experiences and the lasting impact of traumatic brain injuries are available from the source, including resources for those who may be struggling with similar issues.
