Effects of Acute Hypoglycemia on Cognitive Function in T1DM
Effects of Acute Hypoglycemia on Cognitive Function in T1DM
Mood is often assessed in two basic domains, namely tense arousal (feeling anxious or nervous rather than relaxed or calm) and energetic arousal (feeling lively and active rather than tired and sluggish). Hedonistic tone (happiness versus sadness) can also be evaluated. Hypoglycaemia provokes negative emotions. Tense arousal is increased and energetic arousal is reduced, producing a state of 'tense tiredness', a combination that is rarely observed in response to any other type of stress. Hedonistic tone declined in non-diabetic health care professionals during experimental hypoglycaemia, who on questioning expressed a much more pessimistic view of their career prospects. Feelings of anger also increase in some people during hypoglycaemia. In non-diabetic individuals it takes around 30 minutes for mood to be restored to baseline following experimental hypoglycaemia.
Motivation is another important determinant of performance, and this has been assessed during hypoglycaemia using the Dundee Stress State Questionnaire. Motivation declined as testing progressed, both in the experimental and control arms. Reduced motivation was apparent in the hypoglycaemia arm, and perceived workload was higher.
Negative mood, poor motivation, and anger during hypoglycaemia may have an adverse effect on many activities including sport, recreation, interpersonal relationships and work performance. These emotional changes may also have an impact when using experimentally-induced hypoglycaemia to test cognitive function, which cannot be tested in isolation. The profound effect that hypoglycaemia exerts on mood and emotions is frequently overlooked and may contribute to the development of chronic anxiety states or depression.
