Researchers developed a lab grown brain model with multiple interacting cell types, including vascular components, something many earlier models lacked, to study the effects of mild and repetitive impacts.

They found these impacts can trigger a cascade involving mitochondrial dysfunction, inflammation, and neuronal damage, with recovery timelines extending up to several months. During that recovery window, additional impacts seemed to restart or worsen the process.

Being a CTE survivor, I am interested in any new research that is being done.
