Does sleep deprivation permanently affect...

[Amu]

...intelligence? Suppose you need 6-7 hours of sleep a night and you actually sleep 4-5 hours. I know this will drop intelligence temporarily but what about permanently. If the person starts sleeping normally after a year, will he/she FULLY recover his/her intelligence (IQ, coordination, memory; the lot)

The more memory gets screwed up the harder its to sort out reality from fantasy. I believe something like a math problem or another type of problem in logic could help with finding out if and how bad the memory is screwed up..Memory patterns can be restored if the right amount of repetitions are given ....but coordination and the rest for the most part starts to come back almost instantly once when a pattern has been restored!
