Zusammenfassung. Zielsetzung: Die Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) im Erwachsenenalter tritt sehr häufig gemeinsam mit Störungen des Substanzkonsums (SUD) auf. Es gibt Befunde, dass beide Erkrankungen mit veränderten neuronalen Prozessen in frontalen Netzwerken assoziiert sind, was im Einklang mit aufgezeigten Beeinträchtigungen in Exekutivfunktionen (EF) steht. Dieser Übersichtsartikel wird den aktuellen Forschungsstand darstellen und darauf eingehen, inwiefern EF einen verbindenden Faktor zwischen beiden Störungen und ihrer zugrundeliegenden Pathogenese darstellen könnten. Methodik: Für diese narrative Übersicht wurde eine pubmed-Literaturrecherche durchgeführt. Ergebnisse: Neben dem gehäuften gemeinsamen Auftreten von ADHS und SUD zeigt sich insbesondere, dass aus der Störungskombination eine stärkere Beeinträchtigung der EF resultiert. Betroffene Patienten weisen frühzeitige, persistierende und besonders starke EF-Störungen auf. Außerdem finden sich EF-Veränderungen bereits in Risikopopulationen für ADHS und SUD und sagen eine spätere SUD zum Teil voraus. Schlussfolgerungen: Die Ergebnisse weisen darauf hin, dass exekutive Dysfunktion einen neurokognitiven intermediären Phänotypen darstellen könnte, der sowohl bei der Pathologie der ADHS als auch der SUD eine Rolle spielt. Dies sollte beim diagnostischen und therapeutischen Vorgehen beachtet werden. Bei EF-Störungen im Kindes-/Jugendalter können präventive Therapiemaßnahmen zur Stärkung dieser Funktionen frühzeitig eingeleitet werden.

Smoking is among the leading causes of mortality worldwide. Discontinuing smoking can increase life expectancy to the presmoking level. Unaided attempts are often ineffective, strengthening the necessity of cognitive-behavioral therapy (CBT), nicotine replacement or pharmacotherapy. Still, relapse rates are high. Recently, a modulation of nicotine craving, which predicts relapse, through transcranial magnetic stimulation to the prefrontal cortex was shown. In a pilot study, we investigated whether 4 sessions of intermittent theta burst stimulation (iTBS) as add-on treatment to CBT reduces nicotine craving and improves long-term abstinence (at 3, 6 and 12 months). Smokers were randomly assigned to a treatment (n = 38) or a sham group (n = 36). Although we did not find reduced craving, we could show higher abstinence rates in the treatment group at 3 months. At 6 and 12 months abstinence rates did not differ significantly. Results at 12 months, however, have to be interpreted cautiously due to significant differences in the dropout rates between the two groups at this time point. We provide first evidence for a beneficial effect of additional iTBS on intermediate nicotine abstinence; however, the low number of iTBS sessions might have prevented longer effects. More lasting effects might be achieved by iTBS maintenance sessions in analogy to the treatment of depression.

Background: Reliable population-based data on the prevalence and characteristics of primary headache across the lifespan are essential. However, robust data are lacking. Methods: We utilized questionnaire data from a random general population sample in Germany, that comprised 2,478 participants aged ≥14 years. A standardized questionnaire addressing headache and headache treatment was filled in during the face-to-face survey. Results: The 6-month prevalence of self-reported headache in the total sample amounted to 39.0% (known diagnosis of migraine 7.2%; tension-type headache 12.4%; another diagnosis or unknown diagnosis 23.4%). Age-specific prevalence rates were 37.9% (14-34 years), 44.6% (35-54 years), 38.5% (55-74 years), and 26.9% (≥75 years). Compared to age group 14-34, participants aged 35-54 were more (OR = 1.29, 95%-CI 1.05-1.60, p = 0.018) and those aged ≥75 were less (OR = 0.55, 95%-CI 0.40-0.76, p 14 days per month. The frequency of headache did not differ significantly between age groups in men [χ2(3, N = 384) = 1.45, p > 0.05], but in women [χ2(3, N = 651) = 21.57, p 14 days per month: 1.8 (14-34 years), 2.5 (35-54 years), 3.2 (55-74 years), and 3.4 (≥75 years), respectively 7.9 (14-34 years), 11.4 (35-54 years), 18.4 (55-74 years), and 22.8 (≥75 years). Conclusions: In general, the prevalence of headache decreases with age. However, older women suffer from more frequent attacks and older participants take analgesics on more days per month than younger participants. This might put them at risk of medication overuse which may lead to medication overuse headache. More research is needed to understand these specifics in headache frequency and treatment behavior in older people.

Background: Headache sufferers in need of professional health care often do not utilize the care available, and factors influencing headache-specific physician consultation are not yet understood. Objectives of this study are (1) to assess self-reported headache-specific physician consultations and (2) to identify headache-related and sociodemographic predictors. Methods: Data of a random sample of the general population in Germany aged ≥14 years were analyzed (N = 2461). A multivariate binary logistic regression was conducted to identify a parsimonious model to predict physician consultation. Results: 50.7% of the participants with headache reported at least one headache-specific physician consultation during lifetime. Of these, 53.6% had seen one, 26.1% two, and 20.3% more than two physicians because of their headaches. The odds of physician consultation increased with the number of headache days per month (HDM) (reference HDM 1) HDM 1–3 (OR = 2.29), HDM 4–14 (OR = 2.41), and HDM ≥15 (OR = 4.83) and increasing Headache Impact Test score (HIT-6) (reference "no or little impact") moderate impact (OR = 1.74), substantial impact (OR = 3.01), and severe impact (OR = 5.08). Middle-aged participants were more likely to have consulted than younger and older ones (reference 14–34 years) 35–54 years (OR = 1.90), 55–74 years (OR = 1.96), ≥75 years (OR = 1.02). The odds of physician consultation among self-employed subjects were lower than among employed manual workers (OR = 0.48). The living environment (rural versus urban) did not have an influence on the consultation frequency. Conclusion: The results indicate that apart from burden-related factors (headache frequency; headache impact), health care utilization patterns are also influenced by patients' occupational status and age. Further research is needed to analyze whether the lower consultation rate means that the self-employed have a higher risk of chronification or that they have more effective self-management strategies regarding headache.
