Is it true that you stop producing brain cells after the age of 25?
457891
I thought it was just that the body slows down the production of all cells around age 30,,  I know you generally reproduce your entire body every 7 years until it slows at  30 ,, an old dude,,  with old brain cells,,,,,,,

for the record- the test you get at 8 years old is NOT the same as when youre an adult.  AND YES it will change from 8 years old to when youre older, WHY? Because your database of experience has increased, or OUGHT to have. Your BRAIN size also increases because your SKULL hasnt "completely closed" BY COMPARISON at 8 years old compared to 22. Example being, ONE part of standard IQ test, will test to see if you KNOW certain words and what the words are SIMILAR to. One cant expect an 8 year old to know the same words that a college grad has been exposed to concidering that the words they test you on, are college level words. IQ test online ought not be t aken seriously theyre put out by schools who want to fool you into believing that you possess a high score, in oreder to sign up at their school. You can see this because AFTER the test, youre greeted by ads to 'further your education' at slect schools. REAL IQ tests take HOURS to be administered and the one I had was over 4 hours and had the whole Warshak  Ink Blots test and I got to be timed while putting together red and white divided cubes to match flash cards of complex designs. Now, when you have an IQ test as an ADULT and you have another one say, 15 years later your test score is 'supposed' to be the same. Your brain ought to be the same as it was because 'everything' is supposed to stop growing by the time youre AROUD 22 on average. BY THIS they mean that it varies PLUS or MINUS by 15 points. THIS is due to the same reason we miss anything on a test, we GUESS some answers that we dont know, especially because its a timed test. Its also do to HOW you feel that day, and if youve had enough sleep etc etc. So the score will vary for these reasons. You cannot expect the scores to be anything like that of an 8 year olds. If you havent improved your intellect from an 8 year old to adult hood, somethings impairing you. Im leaving my quickly typed typos in to see if some lamer dares to point out how dumb I must be.

no because of the effects it can do on your brain at that young age is really bad b/c ur so young and small drink can cause horible damage to your brain. but as you get older u get bigger and your organs can filter out the alcohol easier.

Mild atrophy - the brain is slightly shrunken compared with the "normal" appearance of a 20 or 30 year old brain. If you are in your 50s or above, mild atrophy is pretty much normal, and if you're in your 70s or above it's very good! (most of them have "moderate to severe atrophy.")\n\nPeriventricular and subcortical nonspecific white matter changes - is a common neuroradiology phrase on MRI. It means there are tiny blips of high signal in the white matter (nerve fiber tracts - as opposed to the grey matter which are the "bodies" of the nerve cells), which indicate there has been some damage or tissue loss there. They are "nonspecific" because they are *not* caused by known pathologies like multiple sclerosis, HIV, "mad cow", or other infections. The accepted explanation is that they are caused by tiny areas of insufficient blood supply - like very very tiny strokes. Again, this is a common finding in scans on older people; however, if it gets severe, it may produce dementia.\n\nChronic microangiopathic disease - this means problems with the tiny blood vessels (micro = small, angio = blood vessel, path/pathology = diseased) that is chronic (long-standing) as opposed to acute (like in a sudden stroke). This is common as we age - the tiny blood vessels get a bit stiff, crackly, sometimes blocked. As a result, the deeper areas that they supply don't get enough blood and some of the white matter is damaged, leading to overall brain shrinkage.\n\nThis is not a particularly worrying report (depending on age.) However, if you are a smoker, or have high blood pressure, and/or have other risk factors for stroke (family history, personal history of heart or peripheral blood vessel disease, high cholesterol) you should see a doctor for advice about improving your lifestyle.

Sorry! It decreases with age. After 30 yrs old there is a decline in the amount of testosterone produced.

yes the brain cells can regenerate.. by process called WALLERIAN DEGENERATION(here degenerate means the dead cll has to gone off first later new one will regenrate... firt of all u have to knw wht r the cells in brain , most of are neurons..and other supporting cells like .neuroglial cells,ependymal cells,schwann cells. satellite cells(ofcourse they r named as they surround peripheral ganglia(ganglia means bunch of neurons )).\nhere wallerian degeration is happend in axon(stem) of neuron.  but it depends of type of injury to axon(whether whole or partial axon is involved).

The more active your mind is, and the more pathways you have built in your brain, the longer it takes for you to degenerate.  It's no guarantee.

of course its never confirmed,however some neuro surgeons believe long time usage can cause cell damage

no. as soon as the brain is cut off from the body. the body would not walk.

wait until you are 35.

During prenatal development, enough "stem cells" differentiate into neurons that each newborn infant has enough multipolar neurons to last a lifetime.  While neurons die continually throughout the life span, barring accident or disease, we still have plenty of neurons left, even into the 2nd century of life.\n\nHowever, certain diseases (e.g., Alzheimer's Disease) cause premature and widespread death of neurons - with devastating results.  \n\nOne of the great hopes we have for stem cell research is that there is very promising data from animal models that "flooding" a neuron-depleted area of the brain with stem cells can repopulate the lost neurons and reform the neural network.

I did when I was a kid, but now I'm 38 and know better. It doesn't get good 'till you hit 30. I think our idea of "old" tends to change the older we get.

25 years younger than the person you are talking about.

It is possible to have too many waves going into the brain in too short of a period of time...\nNow if you were dying anyway and had nothing to lose, then by all means, if you wanted to help science you should do so and get paid well to leave something for your family...\nHowever, it is not a good idea if you are doing it just for fun or for the money...\nIt could alter your brain wave pattern in some way we may not be equipped to understand yet...

Never say that.  If you do, when your 40, your going to wonder why you didn't go when you were 25.  I'm  22 and I just started last year.  I enrolled in my local community college and I take evening and weekend classes. I found that there are      people of all ages (and I do mean all) starting over.  In my Anatomy class, theres a guy that looks every bit of 60. If your thinking about going back to school please go.  it will benefit you in so many ways. don't ever think its too late.  My first day i was so nervous because I thought I was going to be surronded by a bunch of teenagers (even though it wasn't that long ago for me) but it really wasn't.  Some of my classmates have kids my age.

If you are getting older  could be due to aging process

It has to do with what we now know about the brain and its' development.  Younger than 18 all the parts that you need to cope and use for your self control aren't done until them.  While the brain doesn't finish 'growing' until around 20 -21 by 18 most of what you need to function in an adult world is there.
