Scary happening - being in limbo

A reminder of the timelessness of the Akhirah.

Trapped in his own body for 23 years - the coma victim who screamed unheard

• Misdiagnosed man's tale of rebirth thanks to doctor

• Total paralysis masked fully functioning brain

For 23 years Rom Houben was ­imprisoned in his own body. He saw his doctors and nurses as they visited him during their daily rounds; he listened to the conversations of his carers; he heard his mother deliver the news to him that his father had died. But he could do nothing. He was unable to communicate with his doctors or family. He could not move his head or weep, he could only listen.

Doctors presumed he was in a vegetative state following a near-fatal car crash in 1983. They believed he could feel nothing and hear nothing. For 23 years.

Then a neurologist, Steven Laureys, who decided to take a radical look at the state of diagnosed coma patients, released him from his torture. Using a state-of-the-art scanning system, Laureys found to his amazement that his brain was functioning almost normally.

"I had dreamed myself away," said Houben, now 46, whose real "state" was discovered three years ago, according to a report in the German magazine Der Spiegel this week.

Laureys, a neurologist at the ­University of Liege in Belgium, published a study in BMC Neurology earlier this year saying Houben could be one of many cases of falsely diagnosed comas around the world. He discovered that although Houben was completely paralysed, he was also completely conscious — it was just that he was unable to communicate the fact.

Houben now communicates with one finger and a special touchscreen on his wheelchair – he has developed some movement with the help of intense physiotherapy over the last three years.

He realised when he came round after his accident, which had caused his heart to stop and his brain to be starved of oxygen for several minutes, that his body was paralysed. Although he could hear every word his doctors spoke, he could not communicate with them.

"I screamed, but there was nothing to hear," he said, via his keyboard.

The Belgian former engineering student, who speaks four languages, said he coped with being effectively trapped in his own body by meditating. He told doctors he had "travelled with my thoughts into the past, or into another existence altogether". Sometimes, he said, "I was only my consciousness and nothing else".

The moment it was discovered he was not in a vegetative state, said Houben, was like being born again. "I'll never forget the day that they discovered me," he said. "It was my second birth".

Experts say Laureys' findings are likely to reopen the debate over when the decision should be made to terminate the lives of those in comas who appear to be unconscious but may have almost fully-functioning brains.

Belgian doctors used an internationally-accepted scale to monitor Houben's state over the years. Known as the Glasgow Coma Scale, it requires assessment of the eyes, verbal and motor responses. But they failed to assess him correctly and missed signs that his brain was still functioning.

Last night his mother, Fina, said in an interview with Belgian RTBF that they had taken him to the US five times for reexamination. The breakthrough came when it became clear that Houben could indicate yes and no with his foot.

"Powerlessness. Utter powerlessness. At first I was angry, then I learned to live with it," he tapped out on to the screen during an interview with the Belgian network last night, AP reported.

Laureys, who is head of the Coma Science Group and department of neurology at Liege University hospital, has advised on several prominent coma cases, such as the American Terri Schiavo, whose life support was withdrawn in 2005 after 15 years in a coma.

Laureys concluded that coma patients are misdiagnosed "on a disturbingly regular basis". He examined 44 patients believed to be in a vegetative state, and found that 18 of them responded to communication.

"Once someone is labelled as being without consciousness, it is very hard to get rid of that," he told Der Spiegel.

He said patients suspected of being in a non-reversible coma should be "tested 10 times" and that comas, like sleep, have different stages and need to be monitored.

Houben hopes to write a book detailing his trauma and his "rebirth".

Contesting evolution - a muslim speaks out

Response from http://adamdeen.blogspot.com/2008/09/responding-to-usama-hasans-muslim-apes.html is also relevant.

Knowledge regained

In contrast to their forebears, modern Muslims have a childlike view of science, especially evolution. This needs to changeComments (182) Usama Hasan guardian.co.uk, Thursday 11 September 2008 13.30 BST Article historyProfessor Richard Dawkins recently said that most Muslims were creationists, and their children are taught that the theory of evolution is wrong, which causes a huge problem in schools.

He's largely correct, and the Muslim world desperately needs to debate the matter properly without fear, since science can neither prove nor disprove God. Whereas the Christian world, where Charles Darwin first proposed his thesis, has had a century and a half to come to terms with the theory of evolution, it has only begun to be taught rather recently in the Muslim world, where faith and religious practice is still relatively strong.

No wonder then that the theory is opposed by some religious elements, especially those that are ignorant of science. Snazzy websites, videos and books produced by fundamentalist Muslim "creationists" such as those at www.harunyahya.com, are obscuring clear scientific thinking.

Creation or evolution? Many believers in God have no problem with an obvious solution: that God created man via evolution. Here is some explanation of this view from a Muslim perspective.

I have a background in physical sciences, not biological ones, but there are parallels. Just as we can see clear evidence for the fact that planets, stars and galaxies evolved very gradually over the last 13 billion years since the big bang and weren't just beamed into existence by God, it would seem intuitive that life in its breathtaking variety on Earth also arose through a gradual evolutionary processes. There are plenty of Muslim biologists who have no doubt about the essential correctness of evolutionary theory.

The Qur'an teaches that humanity began with Adam, whose wife Eve was made "of like nature". The raw materials from which Adam was created are variously described as dust, clay and water, ie a mixture of water and minerals found on earth and in its soil. God completed the creation of Adam, breathed his spirit into him and taught him the names of everything. Since the angels were ignorant of these names, he commanded them to bow down to Adam, to symbolise human superiority over angels due to our free will, intelligence, capacity to understand and express ourselves in eloquent language.

One problem is that many Muslims retain the simple picture that God created Adam from clay, much as a potter makes a statue, and then breathed into the lifeless statue and lo! it became a living human. This is a children's madrasa-level understanding and Muslims really have to move on as adults and intellectuals, especially given the very serious scientific heritage of the medieval Islamic civilisation.

Another objection that is sometimes posed is the following: doesn't evolution denigrate and insult all humans, but especially the prophets of God, by insisting that we all originate from apes? I reply that the theory doesn't insult anyone, but does remind us of the humble origins of our created form. This is nothing new or blasphemous, since numerous Qur'anic verses remind us that we are all created from "dust" via sexual discharges: "despised drops of water". Those verses clearly do not insult the prophets. Meanwhile, our spiritual form remains the most exalted, since it is from the spirit of God breathed into Adam: we exist for the most noble purpose of knowing and loving God, freely and after having been given a choice.

Another irony in this whole debate is that several medieval Islamic thinkers had ideas that were broadly similar to the theory of evolution. The 10th-century Persian philosopher Ibn Miskawayh may have had ideas about the natural world that were, broadly speaking, evolutionist. The 14th-century philosopher Ibn Khaldun wrote:

One should then look at the world of creation. It started out from the minerals and progressed, in an ingenious, gradual manner, to plants and animals.

Although Ibn Khaldun wasn't speaking directly about evolution in the modern sense, I don't think he would have had a major problem with Darwin's theory, judging from the passage above. But it is precisely the loss of the heritage of people like Ibn Khaldun that has led to the current, appalling state of science in the Muslim world and the Muslim consciousness
