Depression as a risk factor for Diabetes:neurobiological/psychoneuroendocrinological mechanisms • Depression is an independent risk factor for type 2 Diabetes (Eaton et al., 1996; Kawakami et al., 1999) Evidence for endocrinological mechanisms: Depression is associated with • increased serum glucocorticoids, catecholamines, and growth hormone (which counter the effects of insulin) and • insulin resistance and • secrection of inflammatory cytokines, which could facilitate development of diabetes (Musselmann et a., 2003).

Anxiety Disorders common amongst Diabetics • Hypoglycaemia anxiety • This can be associated with impaired perception of hypoglyaemic symptoms, which increases the probability of unexpected hypoglycaemic episodes and, therefore, the development of severe anxiety. • Specific type of blood-injection-injury phobia • Can lead to irregular insulin injections with all adverse consequences. • Panic Disorder (with or without Agoraphobia) • Panic attacks are often accompanied by very similar symptoms than hypoglycaemic episodes. Hypoglycaemic episodes can, therefore, contribute to the development of Panic Disorder.
Eating Disorders common amongst Diabetics • The management of Diabetes requires patients to constantly be aware and check their food. The cognitive pattern (restrained eating) is typical for patients with Eating Disorders. • Anorexia nervosa and Bulimia nervosa are not more prevalent amongst Diabetics compared to community samples. However: • EDNOS (sub-clinical Eating Disorders syndromes) are more than twice as prevalent amongst young female Type-I diabetics. • Insulin-purging: deliberately reduced insulin intake in order to promote weight-reduction and fat-loss
