Aims: In the present study, the effect of previous detoxifications on prefrontal function and decision making was examined in alcohol-dependent patients. Further, we examined whether the length of abstinence affects cognitive function. Methods: Forty-eight alcohol-dependent patients were recruited from an inpatient detoxification treatment facility and cognitive function was compared to a control group of 36 healthy controls. The patient population was then divided into a group of patients with less than two previous detoxifications (LO-detox group, n = 27) and a group of patients with two or more previous detoxifications (HI-detox group, n = 21) and cognitive function was compared. In addition, cognitive function of recently (i.e. less than 16 days; median split) and longer abstinent patients was compared. We assessed prefrontal function, memory function and intelligence. Results: Alcoholics, when compared to healthy controls, performed worse with regard to the performance index Attention/Executive function. Cognitive impairment in these tasks was pronounced in recently abstinent patients. We found no significant differences between HI-detox and LO-detox patients with regard to the Attention/Executive function. However, in the IOWA gambling Task, the HI-detox group seemed to be less able to learn to choose cards from the more advantageous decks over time. Conclusions: Our results provide additional evidence for cognitive impairment of alcohol-dependent patients with regard to tasks sensitive to frontal lobe function and underline the importance of abstinence for these impairments to recover. We found only little evidence for the impairing effects of repeated withdrawal on prefrontal function and we suggest that executive function is affected earlier in dependence.

  Aims  To estimate the association between depressive symptoms and Type 2 diabetes, as well as previously undetected diabetes, in a large population-based sample in Germany and to determine associated variables.

Methods  We used baseline data on 4595 participants (age 45-75 years, 50.2% women) from the German Heinz Nixdorf Recall study, a population-based, prospective cohort study which started in 2000. Diabetes mellitus was assessed by self report (physician diagnosis or medication), undiagnosed diabetes based on blood glucose levels. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale short form (cut-off ≥ 15 points). We fitted multiple logistic regression models.

Results  The prevalence of diagnosed and previously undetected diabetes was 9.3% (95% confidence interval 8.2-11.6) and 7.6% (6.6-8.8) in men and 6.0% (5.1-7.1) and 3.2% (2.5-4.0) in women, respectively. Compared with non-diabetic women, the prevalence of depressive symptoms was not significantly different in diabetic women (age-adjusted odds ratio, 95% confidence interval 1.48; 0.98-2.24) and women with undiagnosed diabetes (0.67; 0.33-1.36). In men, the prevalence of depressive symptoms tended to be lower in diabetic than in non-diabetic subjects (0.62; 0.35-1.09), but the depressive symptoms were significantly less frequent in men with undiagnosed diabetes (0.30; 0.13-0.70). The pattern remained after further adjustment. Significant associations with depressive symptoms were found for co-morbidities and living without a partner in both women and in men, and for body mass index and activity level in women only.

Conclusions  After adjustment for relevant covariates, the association between depressive symptoms and Type 2 diabetes was heterogenous in our population-based study. In subjects with undiagnosed diabetes, however, depressive symptoms were less frequent in men. Co-morbidities and psychosocial conditions are strongly associated with depressive symptoms.
