Do Brain Cells Grow Back
I saw something about these new pills that grow back or make new brain cells? Is this true and would they be available to buy?
Save your money: Lots of ads these days for great medical breakthroughs, which have been suppressed by the "greedy drug companies", and somehow got to market. Unfortunately your product just doesn't exist yet, and these pills are just a reincarnation of the old-fashioned "medicine man's" come-on! ...Read moreSee 1 more doctor answer
After brain tumor is resected and going thru radiation and chemo how is it determined if the cancer is gone? Just if tumor doesn't grow back?
Why won't my hair grow back after radiation treatment? I had a brain tumor 15 years ago, with intense radiation following chemo. My hair has not grown back since. I'm very self conscious about it and really want it to grow back. Luckily, my hair grows ove
I : I am sorry to hear that you have permanent hair loss. This can occur after radiation therapy for brain tumors, although it is much more unusual today than it was 15 years ago due to better technology that focuses the radiation where it needs to go in the brain and avoids the scalp. Most non-surgical hair growth treatments like rogaine (minoxidil) or low-level light therapy do not work well in this situation because the number of hair follicles in the area of hair loss is decreased. There are some institutions and doctors that have performed surgical procedures to reverse the hair loss. If the skin is not scarred and is otherwise healthy, there has been some success with hair transplants like the ones men can get for male pattern baldness. If the skin is more significantly changed by the radiation or there is notable scaring, these types of procedures to transplant hair follicles are unlikely to work and more extensive reconstructive surgery using a tissue expander where they put a balloon under the skin and stretch out the normal skin nearby and then move the new skin over the bald patch has been tried. It's a lot to go through for a cosmetic problem and insurance probably won't pay for it. The risks of a healing problem after the surgery might also be a bit higher from the prior radiation. If you are really interested in pursuing this further, i'd try to find a plastic surgeon in your area with experience caring for burn patients as similar reconstructive techniques are used. ...Read moreSee 1 more doctor answer
No: I assume "brain cells" means neurons and not any of the several other types of "brain cells." Gradual loss of neurons occurs throughout life. Neurons that are destroyed by disease e.g. stroke do not grow back. Improvement occurs because the brain tries to reorganize itself to take over the functions that were performed by the lost tissue. ...Read more
During development : of the brain, about 1 1/2 times the number of neurons are formed than are found in the adult brain. The ones that are "extra", for a variety of reasons, are "pruned." There is an association between larger head/brain size & Autistic Spectrum Disorder. One theory is that normal " pruning" doesn't occur. So, having more brain cells may not be completely positive. Good question for you to work on! ...Read more
No for neurons: I interpret your questions to mean that if you have an injury or stroke and there is a loss of brain cells, will they grow back? The classic answer with neurons (these are the ones important for thinking and movement) is that they do not regenerate. These are also the most sensitive to injury. Other types of brain cells such as the glia or microglia are not as sensitive to injury. ...Read more
Hello dr, I had a MRI of my brain. It came back as slight chronic microvascular ischemic changes. What does that mean? Also what does a air cell mean?
Aging changes: As we get older, arteries harden and we see small vessel changes in the brain due to aging. They simply mean the brain doesn't work as well as it did when we are young and mostly attest to our slowly diminishing function. These are microvascular ischemic changes. You probably don't notice these changes. Air cells are bony areas of the skull with air spaces in them- normal. ...Read more
