- Background: Non-motor symptoms (NMS) in patients with dystonia have a relevant impact on health-related quality of life; however, a comprehensive easy to use NMS assessment tool for clinical bedside use is currently not available. Objective: The validated German version of the dystonia non-motor symptoms questionnaire (DNMSQuest) for assessing NMS in craniocervical dystonia is presented. Methods: The DNMSQuest in the German language was developed based on internationally recognized standards for intercultural adaptation of self-completed patient questionnaires. Translation of the original English questionnaire into the German language as well as back translation to English was carried out independently by four bilingual specialists in neurological movement disorders. In each case a consensus version accepted by each translator was created by another neurologist. The back translated English version was compared with the original English questionnaire for relevant linguistic and content discrepancies by a neurologist who was significantly involved in the development of the original questionnaire. The final German version was used in 130 patients with cervical dystonia and 48 healthy controls in an international, multicenter validation study. Results: An interculturally adapted validated version of the DNMSQuest in the German and English languages was developed for rapid bedside assessment and evaluation of NMS in cervical dystonia. Conclusion: The DNMSQuest successfully bridges the current gap of a validated disease-specific, patient self-administered, short, comprehensive questionnaire for NMS assessment in routine clinical practice in craniocervical dystonia. It is envisaged that this tool will be useful for the clinical practice and trials.

- Pioneering papers by Munday and colleagues have reported profound effects of end-of-century ocean acidification—simulated by experimentally elevated CO2 levels in seawater—on the behaviour of coral reef fishes, such as extreme attraction of prey species to the chemical cues of their predators. Later studies by the same group reported that a range of other behaviours of coral reef fishes, including swimming activity, behavioural lateralization, homing and different predator avoidance behaviours, were also impaired by ocean acidification and that predator-escape behaviours in a coral reef mollusc were also impaired through the same physiological mechanism reported for fishes (that is, through effects on ‘GABAA-like receptors’), which led to the idea that “elevated-CO2 could cause behavioural impairment in a broad suite of marine animals”. In 2014, we initiated experiments to further explore the physiological mechanism(s) that impaired coral reef fish behaviour in elevated levels of CO2; however, we immediately ran into a problem: despite several attempts, and many improvements to the standard methodology used in this field, we were unable to observe an effect of ocean acidification on fish behaviour. Our initial goal changed from what was meant to be a series of original experiments into a three-year effort to transparently examine behavioural effects of ocean acidification in coral reef fishes; the findings of our study are the basis for the accompanying Comment by Munday et al.
