Smerte et symptom på skade eller er det noe mer komplekst?

Smerte er noe vi alle kjenner til og fra (heldigvis), men ikke alle føler den hele tiden. Vi har ennå ikke funnet ut hvorfor noen blir bra etter en akutt skade/smerte, mens andre ikke blir bra og utvikler langvarige smerter. Det man veit er at skaden ikke er noe verre i utgangspunktet, og man veit også at det ikke handler om et personlighetsproblem. #MT  

En av de fremste innen smerteforskning, Prof Lorimer Moseley, svarer her på relevante spørsmål knyttet til dette; Hva er smerte? Er smerte et symtpom på en skade i vevet eller noe mer komplekst?

Anbefales!

Et lite utdrag:

"The International Association for the Study of Pain defines pain as an experience. Pain is usually triggered by messages that are sent from the tissues of the body when those tissues are presented with something potentially dangerous.

The neurones that carry those messages are called nociceptors, or danger receptors. We call the system that detects and transmits noxious events “nociception”. Critically, nociception is neither sufficient nor necessary for pain. But most of the time, pain is associated with some nociception.

The exact amount or type of pain depends on many things. One way to understand this is to consider that once a danger message arrives at the brain, it has to answer a very important question: “How dangerous is this really?” In order to respond, the brain draws on every piece of credible information – previous exposure, cultural influences, knowledge, other sensory cues – the list is endless.

How might all these things modulate pain? The favourite theory among pain scientists relies on the complexity of the human brain. We can think about pain as a conscious experience that emerges in response to activity in a particular network of brain cells that are spread across the brain. We can call the network a “neurotag” and we can call the brain cells that make up the neurotag “member brain cells”."
