Lack of sleep can cause brain damage

Can interrupted sleep patterns cause irreversible damage ? Image Credit: sxc.hu
Failing to get enough sleep could not only make you tired, it could permanently damage your brain cells.
Researchers at the University of Pennsylvania conducted a series of experiments by keeping mice awake for periods of time intended to mimic the interrupted sleep patterns of people whose work shifts forced them to sleep during the day and stay awake at night.

The results revealed that the mice seemed to lose up to 25 percent of their brain neurons on a permanent basis. Previous studies had also confirmed this brain cell loss but up until now scientists had believed that the damage was only temporary.

"In general, we've always assumed full recovery of cognition following short and long-term sleep loss," said lead author Prof Sigrid Veasey. "But some of the research in humans has shown that attention span and several other aspects of cognition may not normalize even with three days of recovery sleep, raising the question of lasting injury in the brain."

As a long term insomniac I guess I'm screwed. I figured most of my cognitive impairment was just coming with old age. Yeah I'm a long term insomniac too,I also start work at 4am each day.I guess I'm going to be a vegetable in a few years time

I guess we can't take it the other way. IF so, my wife would be the smartest person on the planet. I swear she sleeps more than she's awake. Five minutes after she gets home she's asleep.( A slight exaggeration, but you get the point.)

My wife even has fallen asleep standing up. It runs in her family. My mother-in-law can do the same thing.

As a long term insomniac I guess I'm screwed. I figured most of my cognitive impairment was just coming with old age. Crikey. I haven't gotten a decent night's sleep since I was a teenager. I'm lucky to have more than 2 brain cells left at my age.

How long have the people who created this, studied a number of people in a sleepless environment, or have they just used it as a thesis to get through an exam.AAAaaarrrgh,gotta go my brain just fell out of my ear.

Sleep loss may be more serious than previously thought, causing a permanent loss of brain cells, research suggests. In mice, prolonged lack of sleep led to 25% of certain brain cells dying, according to a study in The Journal of Neuroscience. If the same is true in humans, it may be futile to try to catch up on missed sleep, say US scientists. http://www.bbc.co.uk...health-26630647 Do you have any idea just how the electrosmog influences our quality of sleep? Is this electrosmog deliberately designed to create brain cell loss in us? I am telling you, last night, I slept for 10 hours straight, ... [More]

Now they should do another study to see if any of the cognitive damage could be repaired by administering doses of cannabis. I have read studies that suggest certain compounds in cannabis can aid in braincell growth. Seems like a perfect opportunity for further research.
