“CTE is linked to repetitive brain trauma and has a distinct pathology that can only be diagnosed at autopsy,” says Dr. Ross Zafonte, a principal investigator of the Football Players Health Study at Harvard University and executive vice dean at the University of Missouri School of Medicine.

The changes that occur in traumatic brain injury are generally too small and too subtle to pick up on brain scans, unlike strokes, says Dr. Maura Boldrini, professor of psychiatry at Columbia University Medical Center. “We are talking more about microstrokes in which repeated shaking can cause the capillaries [tiny blood vessels in the brain] to break. This leads to some leaking into the brain and starts the process of inflammation, which can lead to the death of brain cells and brain neurons.”

We explain what we know about the disease after the shooting in Manhattan.

Somatic, mind-body therapies could bridge the disconnect to heal from trauma.

As emergency responders focus on clearing debris and searching for victims, a less visible and slower disaster has been unfolding: the need for ongoing mental health support long after headlines fade.

This phase is no less critical than restoring power or rebuilding bridges. Disasters destabilize emotional well-being, leaving distress, prolonged recovery and long-term impacts in their wake long after the event is over.
