The study, based on unique tissue samples from Denmark’s Brain Bank at SDU, could pave the way for new treatments that help the brain heal itself.
This was announced in a press release.
The Challenge of Repairing Brain Damage
A stroke occurs when blood supply to a part of the brain is blocked, leading to brain damage.
After a stroke, the brain attempts to repair damaged nerve fibers by restoring their protective layer, myelin.

Unfortunately, this repair process is often only partially successful, which means that many patients suffer long-term physical and mental impairments.
According to professor Kate Lykke Lambertsen, one of the study’s lead authors, the brain has its own ability to heal—but it often struggles under difficult conditions.
“We need to find ways to help the cells complete their work, even in challenging environments,” she explains in the press release.
Researchers have focused on how inflammation prevents proper healing.

The study identified a specific type of brain cell that plays a key role in the repair process. These cells work to rebuild myelin, but inflammatory responses often block their efforts.
Men and Women React Differently to Brain Injuries
An intriguing discovery in the study is that men’s and women’s brains respond differently to stroke-related damage.
“These differences highlight the importance of developing more targeted treatments that consider a patient’s sex and individual needs,” says Lambertsen.
In women, inflammation appears to interfere more with the brain’s ability to repair itself, whereas men seem to have a slightly better capacity to initiate the repair process.

This difference may explain why women often face greater difficulties recovering from a stroke.
