Well, that is a complicated question it is not a simple matter of good or bad things happening after eating junk food.
For example, it would all depend on who the person is, is their brain healthy, are they young or old, how bad is the junk food? etcetera.
Though I would imagine if the junk food is highly processed and doesn't offer much nutrients it will be a burden on the whole system. Not just the brain.
However, there are studies that show negative consequences from certain junk foods,
E-numbers, preservatives, modified fats and proteins etc.
Typically the bad fats have an adverse affect on the brain since the brain uses fats more intricately than other systems. There could even be blood clots.
Like I said it all depends.
