Iran War Renews Concerns About Brain Injuries to US Troops
The lasting effects of traumatic brain injuries are raising fresh concerns about the toll of the Iran war on American troops. Nearly 700 US service members have been wounded by drone and missile attacks on bases in the Middle East, and military officials say the majority have suffered traumatic brain injuries.
Most of the wounded troops have returned to duty after their injuries, according to public statements from military officials. But doctors have no way to predict who will suffer lasting problems — a vexing question that has gained renewed attention as the conflict continues without a clear end.
What Are Traumatic Brain Injuries?
Traumatic brain injuries, or TBIs, occur when a sudden force or impact damages the brain. In military contexts, TBIs are commonly caused by explosions, blasts, and concussive events. The injuries range from mild concussions to severe brain damage that can result in permanent disability.
The Pentagon's chief spokesman, Sean Parnell, recently described the vast majority of injuries from a two-week period as minor concussions. However, medical experts caution that even mild TBIs can have significant long-term consequences.
"There's no such thing as a minor brain injury," said Dr. David Hovda, director of the UCLA Brain Injury Research Center. "Every concussion is a disruption to normal brain function, and we're still learning about the cumulative effects of multiple concussions."
Between 2000 and 2025, more than 500,000 US service members were diagnosed with TBIs, with 82% of cases considered mild. Advocates say the injuries could still be undercounted because symptoms often overlap with post-traumatic stress disorder and other conditions.
How the Iran War Is Different
The Iran war has introduced a new type of warfare that is creating different patterns of brain injury than previous conflicts. Unlike the wars in Iraq and Afghanistan, where roadside bombs and improvised explosives primarily caused TBIs through ground-level blasts, the Iran conflict features drone and missile attacks that may explode closer to troops' heads.
"In Iraq and Afghanistan, the blast wave from an IED would come up through the floor of a vehicle," explained Dr. James Kelly, a neurologist who has treated thousands of veterans with TBIs. "In this conflict, we're seeing drones that detonate at head level, which can cause more direct brain injury."
The nature of drone warfare means that troops may experience multiple blast exposures over time, even if each individual event seems minor. Research has shown that cumulative blast exposure can lead to progressive brain damage, even when each individual blast doesn't cause immediate symptoms.
The Port Shuaiba Incident
The concerns about TBI care have been heightened by the ongoing investigation into an Iranian drone strike at Port Shuaiba in Kuwait that killed six US soldiers on March 1. Democratic lawmakers are calling for a full investigation into the care that wounded troops received following the attack.
Wisconsin Senator Tammy Baldwin pressed the military this week to release the findings of its investigation into the attack. "I spoke directly with Wisconsinites who sustained traumatic brain injuries from Trump's war in Iran and went weeks without so much as a screening, let alone specialized care, for their injuries," Baldwin said.
The Defense Health Agency has stated that it is policy that service members are screened for TBI, but advocates say the screening process is often inadequate and that many troops fall through the cracks.
The Port Shuaiba incident has become a focal point for批评 of the military's TBI care, with critics arguing that the system is not prepared to handle the volume of brain injuries generated by the Iran conflict.
Long-Term Consequences
The long-term consequences of TBI can be devastating for both individuals and their families. Common symptoms include chronic headaches, memory problems, difficulty concentrating, mood swings, and sleep disturbances. In severe cases, TBIs can lead to dementia, depression, and an increased risk of suicide.
"I'm still dealing with forgetfulness after so many years out of the military," said Army veteran Spencer Milo, who sustained multiple TBIs during his service. "It affects everything — your relationships, your ability to work, your quality of life."
The economic costs of TBI are also significant. A study by the RAND Corporation estimated that the lifetime cost of caring for a single veteran with a severe TBI can exceed $3 million. With hundreds of thousands of veterans affected, the total cost to the VA system could run into the hundreds of billions.
For the troops currently serving in the Iran war, the uncertainty about their long-term health is a source of significant anxiety. Many have seen colleagues return from deployments with cognitive difficulties and mood changes, and they worry about their own futures.
What's Being Done
The military has made significant strides in TBI screening and treatment in recent years, but advocates say much more needs to be done. The Defense Department has invested in new diagnostic tools, including blood tests that can detect brain injury biomarkers, and has expanded its network of TBI treatment centers.
However, the system still faces significant challenges. Many military medical facilities lack specialized TBI expertise, and troops in combat zones often have limited access to neurologists and other brain injury specialists.
Congress has also gotten involved, with several lawmakers introducing legislation to improve TBI care for service members. The proposals include mandatory screening for all troops returning from combat zones, expanded access to specialized treatment facilities, and increased funding for TBI research.
"We owe it to our troops to take care of them when they're injured," said Senator Baldwin. "That means providing proper screening, timely treatment, and long-term support for those who suffer brain injuries in service to our country."
What This Means for Military Families
For military families, the TBI crisis adds another layer of stress to an already difficult situation. Spouses and children often bear the brunt of caring for loved ones with brain injuries, and the effects on family dynamics can be profound.
"When your husband comes home and he's not the same person you sent off, that's incredibly difficult," said Maria Gonzalez, whose husband sustained a TBI during a deployment. "You have to learn to live with someone who has mood swings, who can't remember things, who sometimes doesn't even recognize you."
Support groups and family counseling services have become increasingly important as the number of TBI-affected families grows. Organizations like the Brain Injury Association of America offer resources and support for families navigating the challenges of life after brain injury.
As the Iran war continues, the TBI issue is likely to remain in the spotlight. The troops who serve deserve to know that their injuries will be properly treated and that their families will be supported — now and in the years to come.
