The Morning Muster: A Column For and By Veterans

Invisible Wounds: Combat TBI and Early Onset Dementia

For many veterans, stepping away from a combat zone and returning to normal life feels like  reaching a safe haven. Once the deployment ends, weapons are turned in, and the immediate threats from direct engagement  subside. But for the thousands of service members who answered the call in Iraq and Afghanistan, an unseen burden, whose damage is not revealed until years later, came home with them.

Traumatic Brain Injuries (TBI) are largely discussed in terms of immediate symptoms, such as headaches, light sensitivities, and dizziness from concussions sustained during an improvised explosive device (IED), breaching exercises, or artillery fire. However, what often gets overlooked is the long term neurodegenerative impact, including the astonishing link between combat related TBIs, repeated low-level blast exposures, and early onset dementia.

The Hidden Mechanics of Blast Trauma

Unlike visible wounds like broken bones, or shrapnel lacerations, blast injuries operate on a microscopic level. Once an explosive detonates, the high pressure shockwaves can pass through biological tissue in milliseconds. The brain experiences rapid pressure shifts that shear delicate blood vessels and tear neural pathways.

Even if you do not lose consciousness, the repeated exposure to explosions from heavy machinery, breaching charges, or motor fire can cause escalating micro trauma. This disruption initiates a chronic inflammatory response in brain tissue, which over time, causes abnormal proteins to accumulate in the brain that damage neuronal communication. This eventually paves the way for conditions like Chronic Traumatic Encephalopathy, dementia, and Alzheimer’s to strike much earlier in combat veterans than their civilian counterparts.

Recognize the Early Signs

Since progression of these conditions happen gradually, initial symptoms might be falsely attributed to normal aging, burnout, or standard PTSD. While PTSD and TBI often overlap, neurodegenerative decline has key indicators to watch for, including:

Short-Term Memory Gaps: Forgetting recent conversations, misplacing important items repeatedly, or the inability to follow daily routines.

Executive Function Breakdown: Issues with multitasking or solving every day problems that were once easy to solve.

Mood and Personality Shifts: Seemingly unjustified mood swings, frustration over minor issues, and impulse control issues.

Speaking Issues: Pausing in the middle of a sentence, struggling to find simple words, or losing train of thought during conversations.

When these symptoms start to appear in younger veterans, it is easy to immediately react with denial and self isolation. However, recognizing these indicators early is imperative in slowing cognitive decline and receiving vital care.

Fighting for Advocacy and Policy Shift

In the past, many veterans with memory issues that arose decades after services have faced uphill battles to prove their conditions were service connected. Fortunately, the landscape has begun to shift due to advocacy from veteran organizers and policy changes.

With the passing of the PACT Act, and increased research from the VA into blast exposure, the medical system is increasingly recognizing TBI as a systemic, lifelong condition and not an isolated event that heals after a few months. In Rockland County, local groups are continuing to press for expanded federal funding, specialized neurological screenings, and community care access.

Local Resources in Rockland County

If you or a veteran you love is experiencing the lasting effects of combat blast exposure, such as memory issues and cognitive decline, you are not alone. Rockland County has several direct avenues for evaluations, filing service connection claims, and building a local support system. The local Veterans Service Agency (VSA) in New City has a staff of accredited Veteran Service Officers who can help file service connected disability claims and reopen previous claims, and can link you directly to VA benefits related to brain injury care. The PFC Joseph P. Dwyer Peer Support Program located at the Palisades Center offers vet-to-vet peer connection and hosts weekly walks and monthly events to provide emotional relief and keep veterans from isolating during challenging times.  The VA Hudson Valley Health Care System allows veterans to access neurological care, cognitive therapies, and imaging through their New City Community Based Outpatient Clinic and Castle Point and Montrose facilities.

Continuing the Mission

Just because we have hung up our uniforms does not mean the oath to look after one another has expired. If you notice a fellow veteran pulling away, forgetting details, or struggling to adapt, reach out, Reclaiming health and securing proper care requires the same teamwork we learned in the military. By breaking the stigma around cognitive decline and using the available resources in our community, we ensure that no veteran battles the long term impacts of war alone.
