		<description>I live right by where the attack happened so i have been following this closely. 
Good article but couple issues taken into account

1. he does a history of violence and was actually the first person in north miami beach to be tased by the police. when he was about 17 or 18 he had a fight with his mother and she called 911 saying he was going to kill her. The police officer actually remembers the case and said his eyes looked empty and he could not understand or hear commands made by officers for him to calm down, and they had to tase him several times to get him under control. This is what made me think he had a psychotic break maybe caused by underlying schizophrenia emerging.  his age puts him in the range most men develop the illness and the tendencies were there if you believe the officers story.
2. he had a bunch of pills in his stomach and i don&#039;t know why but they have not been able to identify them, so who knows why they were and what they activated. It was also 95 degrees that day and he walked over 5 miles in the heat.
3. he told his best friend he had some important news but he was afraid no one would understand and his family were deeply religious hatian immigrants who apparently bombarded him with threats of the devil and things of that nature, which to a person in the beginning of schizophrenia, would be very stressful. 
thats all, just wanted to share</description>

		<description>Maybe... he was just hot and hungry.  

AND... he didn&#039;t actually &#039;kill&#039; anybody... he was biting the dude, but not actually eating the flesh.  

Therefore he was not a killer nor a cannibal... he was just hot and hungry!!!

Just kidding... enjoyed the explanations Dr. Novella.</description>

		<description>I&#039;ve done a lit search in PubMed and haven&#039;t found anything that would relate &quot;mitochondrial uncoupling,&quot; to psychiatric disorders. Uncoupling Protein 2 (UCP2) mRNA was increased in the post-mortem brain of schizophrenia and bipolar patients in one study. I just don&#039;t think that &quot;mitochondrial uncoupling&quot; is a diagnosable medical phenomenon. Especially a psychotic episode. The fully developed human brain relies on glucose for energy. Though it could survive on keytone bodies, it only does this during starvation situations.

I wonder if they saved Eugene&#039;s brain for pathological study. Should follow up on it. I think that he was in a socioeconomic group where psychiatric disorders may go undiagnosed &amp; untreated for a long, long time. People in his situation usually end up as a &quot;crazy homeless guy.&quot; It is possible that he had something like a psychotic schizophrenic event; and completely lost touch with reality. 

Also, I don&#039;t think we should refer to him as a cannibal anymore. He didn&#039;t swallow the tissue, and it doesn&#039;t seem as though he was planning or choosing to eat human flesh. The crazy college student in Baltimore is another story, though. I would call him a cannibal because he saved specific parts for consumption.

Also, regarding the clothing thing. We don&#039;t know whether his body temperature was actually elevated or not. During psychotic events, people take their clothes off. Some people have heightened sense of touch or itch or pain and that coupled with a loss of inhibition will cause them to take their clothes off. Probably the disinhibition is enough (I&#039;ve known toddlers who make a habit of getting naked for no apparent reason). If his body temperature were actually elevated, I highly doubt that his brain was actually physically &quot;hot.&quot; I believe that the hypothalamus controls body temperature -- if it was somehow not functioning properly and its sensors indicated that his body temperature was colder than it actually was, it would cause his core body temperature to rise; whatever the heightened emotional state and hormones or neuropeptides were signaling to his hypothalamus was out of control and caused his metabolism to go out of whack to the point that his temperature elevated (or he stopped sweating or something). Maybe this is your UCP response, Daed, but I think it&#039;s a step or 3 in the process, not the cause of his breakdown.</description>

		<description>Nitpick, the brain can function on ketone bodies.  Pretty much any cells with mitochondria can survive on ketone bodies.  Red blood cells don&#039;t have mitochondria and so they require glycolysis.  

There are 3-carbon intermediates in the Krebs cycle that can&#039;t come from lipids and as they need to be replaced, amino acids need to be broken down to supply them.  

A lot of immune cells need to use glycolysis because they need to operate in hypoxic regions of necrotic tissues.</description>

		<description>Etatro, perhaps a minor point but fat cannot be broken down to sugars. Fat supplies energy as ketone bodies. (Technically triglycerides do provide a small amount of sugar but in terms of energy supplied it&#039;s not significant.)

That&#039;s why during starvation muscle tends to be destroyed. The brain can&#039;t function on ketone bodies, so the body digests muscle proteins to create glucose, at the expense of the actual muscle.</description>

		<description>They found what appeared to be undigested pills in his stomach, so other extreme events involving  bath salts led to the initial suspicion. Which begs the question, did they or could they not directly test these &quot;undigested pills&quot;? No one here mentioned that, it&#039;s very much hanging in the air...</description>

		<description>Applying Occam&#039;s razor - the devil made him do it.

Excepting this case of a live victim, what is the intrinsic difference between cannibalism and transplantation?</description>

		<description>I don&#039;t think that it is necessary to assume that he suffered from an psychiatric illness or that his psychosis was drug induced until there is good evidence for it.
I think its perfectly possible that he had something like an brief reactive psychosis: http://en.wikipedia.org/wiki/Brief_reactive_psychosis
It would be interesting to know, if something stressful or traumatic happend to Eugene before his bizarre and violent attack.</description>

		<description>One of the very important signaling pathways that is activated in fight-or-flight is the lowering of nitric oxide.  This is absolutely necessary to generate a high flux of ATP by mitochondria, the normal basal level of NO at rest is what inhibits cytochrome c oxidase and prevents O2 binding.  Mitochondria have to release that inhibition by lowering the NO level, which they do by generating superoxide.  With cytochrome c oxidase blocked, the respiration chain accumulates electrons and becomes reduced, O2 picks up electrons from complex 3 and forms superoxide.  The superoxide pulls down the NO level, cytochrome c oxidase becomes disinhibited, binds O2, O2 is reduced to water, the respiration chain becomes oxidized and superoxide production goes down.  

High rate production of ATP requires a high mitochondria potential which increases superoxide production.  Disinhibiting cytochrome c oxidase allows O2 to be consumed to a low partial pressure which provides the driving force for the passive diffusion of O2 to mitochondria.

The low NO also regulates ATP levels to be low via their combined effects on sGC.  The reduced ATP concentration turns off non-essential ATP consuming pathways to free up more ATP production capacity for running from the bear.  

That low NO also has neuropsychiatric effects.  It is part of what causes roid rage, and many of the rage-inducing effects of stimulants.  There was work done with decorticated cats.  If you remove certain brain centers, cats are ok, until they are triggered to be in a fight-or-flight state.  That state has hysteresis and with those centers gone, they can&#039;t get out of it and so they are in a rage until they die from exhaustion, usually in a few hours.  Fight-or-flight is a global response, you need a global control system to turn it on, and a global control signal to turn it off.</description>
