Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

PTSD Linked to Accelerated Brain Aging

With your risk of PTSD post stroke you doctor needs to prevent it; NOT WAIT TO TREAT IT AFTER THE FACT!

And the prevention solution is simple; 100% recovery!

Since there is a 23% chance of stroke survivors getting PTSD what is your doctor's prevention plan? Not a treatment protocol; a prevention protocol!

PTSD Linked to Accelerated Brain Aging

Summary: A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure at Ground Zero.

These findings suggest that PTSD may contribute to neurobiological aging and increase vulnerability to age-related cognitive decline. The work highlights brain age as a potential biomarker for monitoring neurological health in trauma-exposed populations.

Key Facts

  • Older-Appearing Brains: WTC responders with PTSD showed significantly accelerated brain aging compared to peers without PTSD.
  • Exposure Matters: Longer durations at Ground Zero further amplified advanced brain age effects.
  • New Biomarker: Brain age may help detect early neurobiological impacts of trauma and guide long-term monitoring.

Researchers from the Icahn School of Medicine at Mount Sinai have found that post-traumatic stress disorder (PTSD) may be linked to accelerated brain aging among World Trade Center (WTC) responders involved in rescue and recovery operations after the 9/11 terrorist attacks.

The study, published in Translational Psychiatry, is the first to apply a deep learning-based brain age model to this population.

The team used BrainAgeNeXt, a cutting-edge artificial intelligence model trained on more than 11,000 MRI scans, to estimate each participant’s “brain age.” They found that WTC responders with PTSD had brains that appeared significantly older than their chronological age compared to those without PTSD. Longer exposure duration at Ground Zero further amplified this effect.

“These findings suggest that PTSD is not only a psychological condition but may also have measurable effects on the brain’s aging process,” said Azzurra Invernizzi, PhD, a postdoctoral fellow in the Department of Environmental Medicine at the Icahn School of Medicine at Mount Sinai and the study’s first author.

“Understanding these changes helps us recognize the neurobiological toll of trauma and can guide early interventions to protect brain health.”

The results provide new evidence that the long-term impact of PTSD extends beyond mental health, potentially increasing the risk of age-related neurodegenerative conditions. The study offers a new biomarker—brain age—that could be used to monitor neurological health in trauma-exposed populations.

The findings also underscore the importance of continued monitoring and support for WTC responders as they age, and highlight the need for policies that integrate mental and neurological health care for trauma-exposed populations.

“Many 9/11 responders continue to experience the effects of trauma decades later,” said Megan K. Horton, PhD, MPH, Professor of Environmental Medicine at Icahn Mount Sinai and senior author of the study.

“By applying advanced neuroimaging tools, we’re uncovering how PTSD and prolonged stress may alter brain structure and function over time. This work is crucial for developing strategies to detect and prevent early signs of cognitive decline.”

The study involved collaboration with researchers from the Renaissance School of Medicine at Stony Brook University. It was funded by the Centers for Disease Control and Prevention/National Institute for Occupational Safety and Health, the National Institute on Aging, the National Institutes of Health, and the Swiss National Science Foundation, among others.

“Mount Sinai has long been at the forefront of caring for World Trade Center responders,” said Michael A. Crane, MD, MPH, Medical Director, World Trade Center Health Program Clinical Center of Excellence at Mount Sinai.

“This study exemplifies our commitment to combining neuroscience, environmental health, and advanced computational tools to better understand and address the long-term impacts of trauma.”

Key Questions Answered:

Q: How does PTSD affect brain aging in 9/11 responders?

A: Responders with PTSD showed significantly older-than-expected brain age estimates, indicating accelerated neurobiological aging.

Q: What tool did researchers use to measure brain age?

A: They used BrainAgeNeXt, a deep learning model trained on over 11,000 MRI scans to estimate “brain age” from neuroimaging data.

Q: Why do these findings matter for long-term health?

A: Accelerated brain aging may increase risk for cognitive decline, making brain age a valuable biomarker for monitoring trauma-exposed individuals.
