Hamworld, we have plenty of patience. We told you over and over what would happen if you did not have O2 for 5 minutes, yet you kept asking the same thing over and over.

Understand that patience can wear thin if you have to give the same answer almost 40 different times.

That's an exaggeration! I did not give the same answer 40 times nor was it even close.

Nobody gave the same answers 40 times.

You're right, but the point is giving an answer is only important the first or maybe second time. It's like telling a joke. The joke isn't funny if you have to repeat yourself or explain the answer.

Giving answers to serious questions is nothing like telling jokes.

It could be, and often is, that the questioner needs further and better information, and anything that leads them towards understanding is worthwhile, regardless of the number of attempts it takes to eliucidate the facts.

There is nothing funny about amnesia. I might have had amnesia myself once, but I can't remember.

Yes, it is possible to live with brain damage. A brain deprived of oxygen for five minutes will suffer irreperable damage if the person survives such a long period of anoxia.

I am aware of that. I used the "jokes" thing as a comparison for proving a particular point.

You didn't say anything about dying. Did you mean including death?

I said "if a person survives." If they do not survive, then they are dead. The degree of brain damage will determine life or death. As a rule, five minutes wothout O2 will be fatal (deadly), but some have been found to buck the trend and survive, usually with massively disabling brain damage.

My advice to you is - DON'T TRY IT!

Why is it unlikely to have amnesia?

After being unable to breath for 5 minutes... Is it because you'd die?

Just so!

That's it? That's why? Just because you can die? What a very simple answer.

It is a very simple propblem. Deprived of oxygen for a sufficient length of time the brain is unable to compensate, and rapidly begins to suffer damage. The longer the anoxic period, the greater the damage. When the vital centres are sufficiently impaired brain death follows. There is nothing complicated about it.

Let's say you somehow survived... Why is it still unlikely to have amnesia?

It is neither unlikely nor probable. It is, however, possible, but would depend solely on the area of the brain that was affected.

If you've somehow survived...

I have one more question( I hope) Why does it depend solely on the area of the brain that was affected?

The symptoms of brain damage reflect the area of damage because various functions are controlled by different areas of the cerebral cortex. Thus, damage to the occiptal cortex that controls vision could result in damaged or total loss of vision or visula disturbances depending on the exact locus and extent of the damage.

Prefrontal lobe damage is likely to affect emotional stability or mood, because that is the area of the brain that apparently controls mood.

The most common cause of brain damage, however, is not anoxia or hypoxia, but physical trauma, a blow to the head, and brain heamorrhages - strokes - where blood escapes from one of the vessels that serve the cerebrum and invade surrounding tissues, the damage resulting from pressure on the brain itself from escaping blood, because the brain is encased in a bony box and there is no escape for the extravasated blood.

Again, the degree of damage depebnds on the severity of the bleed or the physical trauma to the brain. Shaken babies suiffer brain damage because the brain sloshes about during violent shaking causing damage as it does so. Put an egg in a box and shake it violently, and what happens to the egg happens to the brain inside the skull during physical trauma.

Is there such a thing as a non-inquisitive question? I encourage youngsters to ask questions. How will they get to know anything otherwise? An unquenchable spirit of inquiry is often evidence of latent genius.

Can being unable to breath for 5 minutes cause cerebral hypoxia? Maybe I'm not being specific. There are plenty of ways that can cause you to be unable to breath for 5 minutes...

What would be the easiest way to give yourself amnesia? Maybe if you had severe depression, you could get amnesia and then forget all the memories.

Depression is not going to give you amnesia.
Like the others said you are more likely to risk brain damage than get amnesia if you try for amnesia.
