It's fairly common, at least for some people, to get brain fog during
the first few weeks of a low/zero carb diet, esp. if they are coming
from a mixed diet, and esp. if that mixed diet was grain-heavy. Similar
to the brain fog many smokers get in the first few weeks of quitting
smoking (increased oxygen flow,for one - in my case, I was a raving
idiot for awhile!!)

The findings of the study also show that once carbs are reintroduced into the diet of participants following a low-carb diet, cognitive functioning returns to normal, pre-study levels".

More research is needed to determine whether this effect on brain functioning continues as a low-carb diet is continued or whether cognitive functioning returns to normal once the body adjusts to being on a new diet."

In the past, when I have experimented with zero-carb I would often find myself "thinking through a fog". Once a small amount of carbs were reintroduced, the fog magically lifted. Now, I realize the body compensates somewhat, but I have my doubts about its efficiency at doing so.
