Well lets analyze point by point shall we?

What does he mean by poisoning? Normal doses of caffiene are not neurotoxic. Sure if you drink too much coffee at once (like any stimulant) it may generate obsessive like symptoms. Though, OCD and ADHD are different disorders, one involves prefrontal overactivity (OCD) and one involved prefronal hypoactivity (AHDH).
>Several factors are involved with OCD. First, >caffeine anaphylaxis poisons the prefrontal >cortex.This is not a scientific statment at all. There is no evidince that caffiene is neurotoxic to the prefrontal cortex. In most animal models caffine is neuroprotective. Caffiene can activate the prefrontal cortex, but this is not poisoning it.
>Obsessive-compulsive disorder is due to >dysfunction of the prefrontal area. (1-3)
He is misusing references. The reference supports that one statment, but not his overall argument.
>Caffeine, a monoamine oxidase inhibitor (MAOI)Caffiene is NOT a monoamine oxidase inhibitor.

>(noradrenaline, adrenaline, and dopamine) >production and delays catecholamine reuptake.It does not affect catecholamine production (in my understanding) but rather release. It does not affect catecholamine reuptake at all.
>Monoamine activity, (4), (5) including an >increase in dopamine activity, (4) is believed >involved with OCD.Yes, too much caffiene may make some OCD worse.
>Due to caffeine's MAOI properties, caffeine >delays serotonin breakdown.Caffine is not an MAOI. Certain compounds in coffee are, but not caffiene.
>A deficiency in >serotonin metabolism is >involved with OCD. (6), >(7)
Well, not according to current theory. Current theory says that serotonin metabolism in OCD is excessive, that is why MAOI's and serotonin uptake inhibitors are used for OCD, because they reduce serotonin metabolism, which would suggest that serotonin metabolism isn't deficiant but excessive.
>Caffeine anaphylaxis reduces cerebral oxygen. >Anaphylactic shock causes circulatory failure, >resulting in decreased blood flow and oxygen.
This is simply talking about people with caffiene hypersensitivity.
>Caffeine reduces cerebral oxygen, (8), (9) and >hyperventilation, a symptom of anaphylaxis, (10->12) contributes to oxygen deprivation.
Caffiene, in nomal doses does not normally produce hyperventalation.
>Commonly, patients diagnosed with OCD suffer a >decrease in cerebral blood flow. (13-15)
It depends on the region of the brain. In OCD certain parts of the brain have a increase in cerebral blood flow.

His use of the term "poisoned brain" is not very scientific. Of course too much caffiene, or any stimulant make OCD worse. You need to know yourself.
>The caffeine allergic individual never suspects >a toxic brain.

It usually does the opposite.

Sure, these are symptoms of OCD.

Caffiene and aphetamine/cocaine are totally different beasts. Not everybody reacts to caffiene this way. Just know how you react to it.

Only some researchers believe this theory. I'm sure these studies were done with stronger stimulants that caffiene.

In some people it may *temporarily* produce some side effects which mimic phychological disorders, like anxiety, or obsessivness, but there is no evidence that it actually causes these disorders.

Caffine does not poison the brain. Quite a few studies have shown that people with the highest intake of caffinated beverages have a lower risk of developing dementia or Alzheimers. There are many studies which suggest that regular intake of coffee helps to preserve cognition over time.
