title: Accelerated post-glucose glycaemia and altered alliesthesia-test in Seasonal Affective Disorder.
abstract: BACKGROUND
  Little is known about the link between mood, food and metabolic function in Seasonal Affective Disorder (SAD).
  
  
  METHODS
  We investigated this link in a combined glucose tolerance-alliesthesia test in eight SAD patients in winter before and after one week light therapy, and in summer.
  
  
  RESULTS
  SAD patients exhibited faster post-glucose glycaemic and insulin responses (p <0.05), and increased hedonic ratings of high concentrated sucrose solutions (p <0.035) when depressed in winter than when euthymic (one week after light treatment or in summer).
  
  
  CONCLUSIONS
  The rapid glycaemic and insulin responses to an oral glucose load may be a result of accelerated gastric emptying.
  
  
  CONCLUSIONS
  The number of studied patients was rather small and no control group was studied in parallel.
  
  
  CONCLUSIONS
  the more rapid post-glucose glycaemia may impair glucose homeostasis in depressed SAD patients.
