I thought it was mainly the brain cells in the hippocampus that get replaced. Others might have some level of regeneration, but not full replacement. I believe antidepressants mimic the process of replacing cells in the hippocampus to give those with depression some kind of mitigation with their negative feelings.
But anyways, I'm almost positive that not everything in the brain is replaced. We come equipped with 100 billion brain cells at birth and I'd be willing to bet that not every one of them is replaced.
