abstract = {Trait-like differences in cognitive performance after sleep
loss put some individuals more at risk than others, the
basis of such disparities remaining largely unknown.
Similarly, interindividual differences in impairment in
response to alcohol intake have been observed. We tested
whether performance impairments due to either acute or
chronic sleep loss can be predicted by an individual’s
vulnerability to acute alcohol intake. Also, we used
positron emission tomography (PET) to test whether acute
alcohol infusion results in an up-regulation of cerebral A1
adenosine receptors (A1ARs), similar to the changes
previously observed following sleep deprivation. Sustained
attention in the psychomotor vigilance task (PVT) was tested
in 49 healthy volunteers (26 ± 5 SD years; 15 females) (i)
under baseline conditions: (ii) after ethanol intake, and
after either (iii) total sleep deprivation (TSD; 35 hours
awake; n = 35) or (iv) partial sleep deprivation (PSD; four
nights with 5 hours scheduled sleep; n = 14). Ethanol-
versus placebo-induced changes in cerebral A1AR availability
were measured in 10 healthy male volunteers (31 ± 9 years)
with [18F]8-cyclopentyl-3-(3-fluoropropyl)-1-propylxanthine
(CPFPX) PET. Highly significant correlations between the
performance impairments induced by ethanol and sleep
deprivation were found for various PVT parameters, including
mean speed (TSD, r = 0.62; PSD, r = 0.84). A1AR availability
increased up to $26\%$ in several brain regions with ethanol
infusion. Our studies revealed individual trait
characteristics for being either vulnerable or resilient to
both alcohol and to sleep deprivation. Both interventions
induce gradual increases in cerebral A1AR availability,
pointing to a potential common molecular response
mechanism.},
