It was a firm belief in science for a long time that brain cells did not regenerate. However, new studies on the brains of primates show that the brain does regenerate and reproduce brain cells.

the answer is yes damaged brain cells can be replaced.

The brain's ability to act and react in ever-changing ways is known, in the scientific community, as "neuroplasticity." This special characteristic allows the brain's estimated 100 billion nerve cells, also called neurons (aka "gray matter"), to constantly lay down new pathways for neural communication and to rearrange existing ones throughout life, thereby aiding the processes of learning, memory, and adaptation through experience. Neuroplasticity is the saving grace of the damaged or disabled brain; without it, lost functions could never be regained, nor could disabled processes ever hope to be improved. Plasticity allows the brain to rebuild the connections that, because of trauma, disease, or genetic misfortune, have resulted in decreased abilities. It also allows us to compensate for irreparably damaged or dysfunctional neural pathways by strengthening or rerouting our remaining ones.

Most of the cells in your body can not reproduce. Only one type of cell in your body can reproduce, stem cells. Depending on where stem cells are, they turn into different types of cells. A stem cell in your muscle will turn into a muscle cell. Stem cells in your liver turn into liver cells. There are some stem cells in your brain. They turn into brain cells. You do your thinking with brain cells. Stem cells are undifferentiated. They can not think. They must turn into specialized cells before they can work.

A better question you should be asking why can't ALL brain cells reproduce? Try reading up on 'neurogenesis'
