Background: The inpatient Parkinson's disease multimodal complex treatment (PD-MCT) was applied more than 15,000 times in 2022, in Germany. This number is increasing as is Parkinson's disease (PD), which affects more than 400,000 people in Germany and leads to 100,000 disability-adjusted life years. In recent years, several observational studies have been conducted on the effectiveness of this kind of multidisciplinary care.

Objective: To summarize and discuss the evidence on the nature, benefits and potential of PD-MCT.

Methods: A narrative review of selected empirical findings was carried out.

Results: The PD-MCT frequently lasts for 2-3 weeks and aims to maintain the quality of life of people with PD. Disease symptoms and activities of daily living are jointly improved by pharmacological strategies and activating therapies (physiotherapy, occupational therapy, speech and language therapy, physical training, art therapy). The PD-MCT is a useful measure to avoid or mitigate crisis situations in the course of the disease. A total of eight observational studies (n = 1246) have shown good effectiveness with a total mean improvement of the International Parkinson and Movement Disorder Society unified Parkinson's disease rating scale III (MDS-UPDRS III) by 7.8 points. The transfer of effects into everyday life through intensive and specialized community-based care must be ensured in order to achieve sustained effects on the quality of life. Ideally, this transfer can be supported by integrated PD networks and digital technologies in the future.

Conclusion: There is potential for development in the standardization, patient selection and quality assurance of PD-MCT as well as in the embedding in care structures such as PD networks. Open research questions include a precise definition of the target group and higher quality evidence of short-term and long-term effectiveness.

Background: Magnetic resonance (MRI) imaging of the skeletal muscles (muscle MRI for short) is increasingly being used in clinical routine for diagnosis and longitudinal assessment of muscle disorders. However, cross-centre standards for measurement protocol and radiological assessment are still lacking.

Objectives: The aim of this expert recommendation is to present standards for the application and interpretation of muscle MRI in hereditary and inflammatory muscle disorders.

Methods: This work was developed in collaboration between neurologists, neuroradiologists, radiologists, neuropaediatricians, neuroscientists and MR physicists from different university hospitals in Germany. The recommendations are based on expert knowledge and a focused literature search.

Results: The indications for muscle MRI are explained, including the detection and monitoring of structural tissue changes and oedema in the muscle, as well as the identification of a suitable biopsy site. Recommendations for the examination procedure and selection of appropriate MRI sequences are given. Finally, steps for a structured radiological assessment are presented.

Conclusions: The present work provides concrete recommendations for the indication, implementation and interpretation of muscle MRI in muscle disorders. Furthermore, it provides a possible basis for the standardisation of the measurement protocols at all clinical centres in Germany.

Hermann Oppenheim (1858-1919) was a German neurologist without an academic career, who in his productive period around 1900 made a name for himself during his lifetime as a major player in the history of German neurology with his many contributions to multiple sclerosis, syphilis and the controversial study of traumatic neurosis; however, it is almost unknown that in 1890 he introduced the term "witzelsucht", which is still used internationally today. Moritz Jastrowitz dealt with behavioral abnormalities due to frontal brain injuries 1 year earlier and used the term "moria" for a form of mental disorder associated with a kind of childish behavior and inappropriate jocularity. Oppenheim was critical of this and differentiated his "witzelsucht" from this. With this term he wanted to describe humoristic feeble-mindedness in a much narrower sense, which stands in striking contrast to the usual symptoms in cases of cerebral tumors. Oppenheim recognized the frontal brain, particularly the right brain, to be an important functional unit for humorous behavior. Modern research has confirmed that the processing of humor requires a complex interaction of multiple brain regions. Damage to the right frontal lobe or to connecting structures can lead to the disorder "witzelsucht". Whether a simultaneous damage to the left hemisphere must be present or if this is dependent on the individual dominant hemisphere, needs further research.

Background: Approximately two thirds of patients with epilepsy become seizure-free with antiseizure medication (ASM). A central question is whether and when ASM can be discontinued.

Objective: To present an overview of the current knowledge about risks and benefits of discontinuation of ASM.

Material and methods: Review of the current literature, discussion of data on and recommendations for discontinuation of ASM.

Results: The risk of seizure recurrence after discontinuation of ASM is approximately 40-50% and thus twice as high as continuing with ASM. Guidelines recommend considering discontinuation of ASM at earliest after a seizure-free period of 2 years. Predictive variables for seizure recurrence after stopping ASM include longer duration of epilepsy and higher number of seizures until remission, a shorter seizure-free interval until stopping ASM, older age at epilepsy onset, developmental delay or IQ < 70, febrile seizures in childhood, absence of a self-limiting epilepsy syndrome, and evidence of epileptiform activity in the electroencephalograph (EEG). The individual risk of seizure recurrence after stopping ASM can be estimated using an online prediction tool.

Conclusion: Discontinuation of ASM should be discussed with patients at the earliest after 2 years of seizure freedom in a shared decision-making process weighing up the risks and benefits. The risk of a seizure recurrence depends on a number of clinical variables. Psychosocial aspects, such as impact on driving and occupational issues must be taken into consideration as well as individual fears and concerns of patients about seizure recurrence or the long-term use of ASM.

This review article explores the intricate relationship between nutrition, metabolism, brain function and mental health. It highlights two key complementary models: the energy balance model and the more comprehensive carbohydrate-insulin model, to understand the development of obesity and metabolic dysfunctions. It particularly focuses on the role of dopamine in dietary regulation and insulin in the brain, both of which are crucial in the pathogenesis of neurodegenerative and stress-associated mental disorders. Additionally, the significance of sleep and dietary habits, such as medically assisted calorie restriction for mental health and the concept of "brain food" are described. These findings emphasize the importance of nutritional medicine in psychiatry and psychotherapy and the consideration of metabolic states for the prevention and treatment of mental and neurodegenerative diseases.

Background: The aim of this article is to summarize the current state of research on the effectiveness of psychotherapeutic treatment of posttraumatic stress disorder (PTSD).

Methods: The results of current meta-analyses and trend-setting individual studies are summarized and the most important forms of intervention are explained.

Results: The psychotherapeutic treatment methods for PTSD are very effective, the effect sizes are large and superior to those of pharmacotherapy. Trauma exposure and cognitive restructuring are most effective. Trauma-focused procedures are generally superior to other forms of psychotherapy. A range of different cognitive behavioral procedures as well as eye movement desensitization and reprocessing are recommended. The most recent initial findings confirm a very good effectiveness for imagery rescripting methods as protective interventions without a formal confrontation with trauma. Individual therapy works better than group psychotherapy. In the group setting cognitive processing therapy has proven to be the best intervention. Trauma-focused treatment should also be used when comorbid conditions such as schizophrenia, bipolar disorder or addiction are present.

Discussion: Trauma-focused psychotherapy in an individual setting is the treatment of choice for PTSD. A large selection of effective methods and well-reviewed manuals are available. The German language S3 guidelines are currently being updated.

Antidepressive pharmacotherapy has undergone various phases in its history. The euphoria of the early years on the relief of depressive symptoms was followed by a long period of clinical experience and intensive scientific work resulting in a more balanced perspective. Current debates circle around the actual effectiveness, especially with respect to long-term treatment, the prevention of suicide and the sequelae of discontinuation of an antidepressant. The evaluation of antidepressants as a group and often also the risk-benefit ratio of an individual treatment change over time. Antidepressants are typical for many forms of psychiatric treatment which, in a term from Hanfried Helmchen, are just as Janus-faced as psychiatry in a general sense is as a science and as a clinical discipline.
