Here is a study going in the other direction, investigating whether a history of concussion increases the odds of COVID becoming long COVID.  This study is just getting started, though:

Some markers in patients' blood during a COVID-19 infection are similar to those in patients who've had a concussion, Linseman said. That suggests that while a viral infection and a hit on the head may feel different to patients, they could share some underlying biology.

And a Denver study looking at the similarities between concussion and long COVID:

“A lot of it is thinking about which parts of the brain are affected when COVID enters,” Stoot says. “If we talk about where our sense of taste and smell is, it’s located in our brain stem. If we talk about the area that gets dinged when you have a concussion, it’s also in our brain stem.”

As expected, the study found similarities between the effects of long COVID and the effects of concussions. While it remains unclear why, both diseases involve brain inflammation, meaning they could involve similar treatments.
