The possible relationship between postsynaptic alpha(2)-adrenoceptor functi
on, as assessed by the growth hormone (GH) response to clonidine (CLON) and
aspects of mental well-being by self-report of mood using the Swedish Mood
Adjective Check List, was investigated in alcohol-dependent patients in th
e early withdrawal period. Patients had blunted GH responses to CLON and wo
rse mental well-being than control subjects immediately after the end of al
cohol intake. No relation was found between mental well-being and postsynap
tic alpha(2)-adrenoceptor function. After 1 week, the GH responses to CLON
remained blunted, whereas the state of mental well-being had improved to le
vels similar to those of control subjects. The results further support a do
wnregulated alpha(2)-adrenoceptor function during 1 week of alcohol withdra
wal. Furthermore, even if subsensitive postsynaptic alpha(2)-adrenoceptor f
unction was not generally related to state of mood, patients with the lowes
t postsynaptic alpha(2)-adrenoceptor function reported the highest levels i
n the dimensions pleasantness/unpleasantness and activation/deactivation wh
en sober.
