Abstract [en]

BACKGROUND: Seasonal affective disorder (SAD) has been regarded as a melatonin disorder, but the pathophysiological mechanisms of SAD are to a large extent unclarified. Serotonergic mechanisms have also been studied, but they have shown inconsistent results. METHODS: We have compared [3H]paroxetine and [3H]lysergic acid diethylamide (LSD) binding in platelets from 23 SAD patients and 23 controls. Then SAD patients had 4 weeks of light therapy. On the last treatment day new blood samples were drawn. Symptoms before and after light treatment were measured by SIGH-SAD. RESULTS: Bmax for paroxetine binding before light treatment was higher in SAD patients compared to controls and also higher in responders than in nonresponders. Bmax decreased significantly during light treatment. We also found a negative correlation between the two Bmax values before but not after light treatment. There was a negative correlation between Bmax for paroxetine binding before treatment and clinical status after treatment. Patients with reduced Bmax for LSD binding after treatment had a better clinical treatment response. CONCLUSIONS: The present study indicates that serotonin receptor parameters might be suitable in the prediction of clinical response to light treatment.
