I don't think regenerate is the right word. I think you mean duplicate and I believe that until recently the answer to your question would have been no. However, I have heard that some people suffering from cerebral palsy, when they're born, if they're left at a colder temperature in an incubator then some of their brain cells "regrow" to some extent and the effects of the disease are therefore lessened. I have also heard that some pregnant women who have a particular type of brain damage, receive stem cells from the fetus growing inside them that help to restore parts of their brain. I'm unsure how true either of these statements are as I have no idea how reliable my sources are.

Neurons are terminally differentiated cells that once lost are generally believed not to be replaced. However, recent studies have indicated that there are reservoirs of neural stem cells that might be able to replace some cells lost to injury or disease. The supply is not vast however, and there are very limited indications for them to overcome any major injuries to the brain. Interestingly, a recent study has shown that in the brain region that is damaged in Parkinson's disease (the substantia nigra), use of a certain class of therapeutic drugs leads to the increase in mitosis (cell division) of cells in this region. The work is still in its early stages but may give us a glimpse of features of the central nervous system that were heretofore unknown.

No, brain cells and certain associated nerve cells do not regenerate. That is why you must be careful how you "spend" them. It is true excessive alcohol consumption does indeed kill brain cells through asphyxiation.
This is one of the reasons it is so hard to recover from a stroke. The brain does have the ability to rewire itself to work around dead cells, but when too much damage occurs in one area this can be a slow and painful process.

They do not regenerate in the sense of the word. They reproduce but eventually they will die. the mental disease Altzimers is the rabid decay of cells related to memory.

In the fully developed human brain, once a brain cell dies it never comes back. But don't worry, most of us have plenty to last us a lifetime!

Nope once a brain cell is dead, it is dead. Other places e.g. your skin can create new cells to replace the old ones which died but that doesn't happen in your brain.

new ones are created but only if you have active life,
active life is not watching TV
you have to make your brain to think so than he will be encouraged to make more cells:)

New brain cells, more importantly new nueral pathways.

There is Neuroneogenesis. But if you find out how it is done, you will get a Nobel prize. Mostly an open question
