RESUMO
BACKGROUND: Regular physical activity is of great relevance in Parkinson's disease (PD). It is part of the inpatient multimodal Parkinson's complex treatment (MKP) in Germany. However, there is often a lack of human resources in outpatient settings to continue an interprofessional approach. A large proportion of PD patients live a predominantly sedentary lifestyle and do not get enough exercise. METHODS: The intervention group (IG) used a tablet-based physiotherapy training programme at home for a period of nine months. We conducted a quasi-randomised longitudinal study with three measurement times (at the beginning (t0) and end of MKP (t1) and at 9 months after MKP (t2)). The primary outcome measured was PD-specific quality of life using the PDQ-8. The secondary outcome focused on participation restrictions, falling anxiety, sleep disorder, anxiety and depression as well as comorbidity, pain, performance capability and physical activity. RESULTS: For n = 93 IG and n = 137 control group (CG) patients, evaluable cases were available for all measurement times. Both groups achieved significant improvements in all parameters at the end of MKP. These parameters deteriorated again at nine months after MKP for most parameters and were even below the baseline levels. However, this deterioration was less pronounced in the IG than in the CG. For general health and social participation, a significant slightly positive effect was observed in the IG nine months after MKP when compared with the baseline level. Paying attention to physical activity slightly increased in the IG for the catamnesis survey compared to baseline. Nearly all IG patients were satisfied with the intervention, especially with the consultations with the physiotherapist. CONCLUSIONS: Although the expected extent of effects could not be determined for the IG, stabilisation effects could be demonstrated. These stabilisation effects shown for the IG might be attributed to the intervention. The effects might have been greater without the COVID-19 pandemic.

BACKGROUND: Hemispatial neglect results from unilateral brain damage and represents a disabling unawareness for objects in the hemispace opposite the brain lesion (contralesional). The patients' attentional bias for ipsilesional hemispace represents a hallmark of neglect, which results from an imbalanced attentional priority map in the brain. The aim of this study was to investigate whether gaze-contingent display (GCD) technology, reducing the visual salience of objects in ipsilesional hemispace, is able to rebalance this map and increase awareness and exploration of objects in the neglected contralesional hemispace. METHODS: Using remote eye-tracking, we recorded gaze positions in 19 patients with left hemispatial neglect following right-hemisphere stroke and 22 healthy control subjects, while they were watching static naturalistic scenes. There were two task conditions, free viewing (FV) or goal-directed visual search (VS), and four modification conditions including the unmodified original picture, a purely static modification and two differently strong modifications with an additional gaze-contingent mask (GC-LOW, GC-HIGH), that continuously reduced color saturation and contrast of objects in the right hemispace. RESULTS: The patients' median gaze position (Center of Fixation) in the original pictures was markedly deviated to the right in both tasks (FV: 6.8° ± 0.8; VS: 5.5° ± 0.7), reflecting the neglect-typical ipsilesional attention bias. GC modification significantly reduced this bias in FV (GC-HIGH: d = - 3.2 ± 0.4°; p < 0.001). Furthermore, in FV and VS, GC modification increased the likelihood to start visual exploration in the (neglected) left hemifield by about 20%. This alleviation of the ipsilesional fixation bias was not associated with an improvement in detecting left-side targets, in contrast, the GC mask even decreased and slowed the detection of right-side targets. Subjectively, patients found the intervention pleasant and most of the patients did not notice any modification. CONCLUSIONS: GCD technology can be used to positively influence visual exploration patterns in patients with hemispatial neglect. Despite an alleviation of the neglect-related ipsilesional fixation bias, a concomitant functional benefit (improved detection of contralesional targets) was not achieved. Future studies may investigate individualized GCD-based modifications as augmented reality applications during the activities of daily living.

RESUMO
BACKGROUND: Parkinson's disease (PD) is one of the most common neurodegenerative diseases. Patients suffer from a variety of motor and non-motor symptoms that severely affect their daily lives and quality of life. In many cases, a three-week inpatient Parkinson's complex treatment (MKP) can improve the overall condition and quality of life of patients in a short time. In the outpatient sector, however, there is often a lack of human resources and structures necessary for the interdisciplinary treatment of the disease. To support PD patients in continuing the physical exercises they learned from the MKP on a regular basis, a tablet-based training programme will be developed in which exercises can be adjusted to the patient's abilities. This programme is expected to increase quality of life and social participation, as well as delay the progression of the impairment. METHODS: a) Quasi-randomized, prospective longitudinal study (sequential study design). The intervention group receives a tablet-based training programme during and for 9 months after the MKP, and the control group receives treatment as usual. The evaluation is carried out by means of a written survey at three points in time (the beginning and end of the MKP and after 9 months). b) Qualitative analysis of interviews and focus groups in terms of feasibility and acceptance. c) Formative evaluation of the app and the administration panel. d) Evaluation of the implementation of the training programme by analysing the planned and performed physical activities, as well as evaluation of the phone calls between physiotherapists and patients. DISCUSSION: The tablet-based training programme can ensure continuous and long-term support for PD patients. They learn different self-management strategies during and after their MKP and are empowered to assume responsibility for carrying out regular physical activity on their own. Because common app stores have no scientifically evaluated apps for PD patients in the German language, the app can fill this gap and help PD patients receive high-quality care in the implementation of physically activating exercises regardless of their place of residence. In addition, the user-centred development of the app ensures that the app meets the specific needs of PD patients. TRIAL REGISTRATION: German Register of Clinical Trials, drks.de .

Epidemiological studies suggest an association of certain foods with the risk of Parkinson's disease. Also, a number of studies revaeled positive effects on disease progression by caffeine, higher uric acid and total cholesterol levels - especially in men. However, it is not yet clear whether a specific dietary concept or the effects of the intestinal microbiota on the human metabolism could play a role in the course of the disease. Given the lack of prospective nutrition studies, only general recommendations can be given: a "balanced" seasonal regional diet with emphasis on vegetables, fruits, nuts, fish, low amount of red meat, and non-processed foods with a low level of simple carbohydrates may be helpful. Especially for the elderly, a low-protein diet should be avoided. Rather, in order to prevent the development of sarcopenia and malnutrition, particular attention must be paid to adequate protein intake. The supply of vitamins B12 and D3 must be ensured - at the same time, the non-critical use of dietary supplements, especially micronutrients with presumed anti-oxidative properties, should be discouraged.

BACKGROUND: Hemispatial neglect is a disabling cognitive disorder following stroke and effective therapies are required. OBJECTIVES: To evaluate the effects of combined optokinetic stimulation (OKS) and cueing-assisted reading therapy (READ) on the remission of hemispatial neglect following stroke. METHODS: Randomized, controlled, two-period, crossover trial conducted at a German neurorehabilitation center. Twenty participants with left neglect following right hemispheric stroke (mean age 66 years (SD 11), mean time since stroke 50 days (SD 33)) finished the trial (12 received OKSREAD first, 8 CONTROL first). The intervention consisted of 15 daily sessions of OKS (20 min) and text reading assisted by a therapist providing cues (20 min). The control treatment was a same-number, same-length neuropsychological treatment not targeting visuospatial attention. Primary outcomes were the change in performance of a customized neuropsychological test battery for neglect (0% worst - 100% best) and a test of neglect-related functional disability (Catherine Bergego Scale, 0 no impairment - 30 severest impairment), assessed before and after each treatment period. Secondary outcomes were performance in the 6 single tests composing the battery (e.g., omissions in text reading, center of cancellation in the Bells test, spatial bias of fixations when freely viewing photographs) and a clinical test of anosognosia. RESULTS: Overall performance in the neglect test battery improved slightly more after OKSREAD than after CONTROL (d=6%; p=0.002). The remission of neglect-related functional disability did not differ between treatments (d=-2; p=0.291). Ipsilesional fixation bias during free viewing was the only secondary outcome that was improved by OKSREAD as compared to CONTROL (d= -2.8°; p=0.005). CONCLUSION: At the applied intensity, the combined OKSREAD intervention slightly attenuated the ipsilesional attention bias in persons with neglect, but it did not improve neglect-related functional disability, anosognosia, or other neglect symptoms to a clinically meaningful degree.

Depressive symptoms in Parkinson's disease (PD) are multifactorial and are partly linked to the underlying dopaminergic deficit. However, at least a subset of PD patients may exhibit an unspecific depressive reaction to chronic illness. Here, we compared the prevalence and severity of depressive symptoms in PD patients and disease controls (DC). PD patients reported depressive symptoms at similar frequencies as DC but were on antidepressants, especially Mirtazapine, more frequently. Still, in both groups, a high proportion of patients with clinically significant depressive symptoms was not receiving medication. Diagnosis and treatment of depressive symptoms both in PD and DC should be improved.
RESUMO
BACKGROUND: During the SARS CoV-2 pandemic, telemedicine experienced an enormous boom. Also, for Parkinson's patients there are upcoming alternatives to regular care. OBJECTIVE: The aim of the present study was to interview Parkinson's patients under the impression of the first lockdown in Germany about their health care situation, but especially about the use of and attitudes towards videotherapy and -consultation. METHODS: Northern German members of the German Parkinson Association were mailed a 16-item questionnaire including demographic questions on a one-time basis. The voluntary participants answered regarding their health care situation during the first German SARS CoV-2 lockdown, as well as attitudes towards videotherapy/-consultations. RESULTS: The 332 (of 974 questionnaires) responding evaluated their care situation predominantly (58.7%) unchanged during lockdown. There was hardly any previous experience in the areas of videotherapy and -consultations (15.4% and 3%, respectively), but at the same time mostly imaginability of implementation (54.2% and 56%, respectively) and the belief that they could motivate themselves to do so (51.8%). A total of 69% welcomed technical support for the implementation of videotherapy. CONCLUSION: In principle, there seems to be both, a need and an interest in telematics in healthcare such as videotherapy and video consultations, even if further barriers such as technical implementation need to be addressed. An expansion of telemedical services and infrastructure seems desirable not only in the pandemic situation, but also in the long term against the backdrop of demographic change, especially in an area like Schleswig-Holstein. Further studies are needed.

OBJECTIVE: To evaluate the point of view of patients with Parkinson disease (PD) on early detection and risk disclosure in the prodromal phase of PD and to derive recommendations for an ethical framework for the recruitment of prodromal PD cohorts. METHODS: A standardized questionnaire to evaluate the patients' perception on early diagnosis in PD was designed by an interdisciplinary study group. After testing in a preliminary feasibility study (n = 20), the survey was performed retrospectively with patients from our clinic. RESULTS: A total of 101 patients with PD answered the questions. The majority of patients reported that time from onset of motor symptoms to diagnosis was burdensome, including false diagnoses and many consultations of various medical specialists. However, most of the patients evaluated early risk disclosure with skepticism. Freedom of choice and the potential of changes in lifestyle were rated as important. CONCLUSION: Although patients with PD reported the time to diagnosis retrospectively as burdensome, the majority was skeptical regarding early disclosure of risk, especially with regard to the lack of pharmacologic options. Circumstances under which early detection and disclosure would have been approved by the majority of patients were (1) advice on lifestyle changes (exercise, nutrition) as potentially disease course-modifying therapy; (2) the establishment of an early diagnosis "culture," including early clarification of the patients' wish to know; and (3) regular support and follow-up of individuals after risk disclosure.

In addition to performance gains accrued concurrently with a given training experience (within-session gains) robust, delayed (between-session) performance gains may slowly evolve in the absence of any additional practice in a variety of tasks. The latter is regarded as a behavioral manifestation of skill memory consolidation. It is not known, however, how much practice is necessary for the triggering of these consolidation effects. Here, using an enumeration task, we show that the triggering of delayed gains could be robustly predicted from each individual's performance curve. Delayed performance gains evolved consistently only when practice continued to the point at which within-session performance leveled off (saturation). No delayed gains were found when training was stopped before this individually determined point. Our results support the notion that the triggering of consolidation processes depends on the saturation of a distinct, early phase of learning rather than on the absolute number of task repetitions, and suggest the possibility that training and rehabilitation protocols could be optimized on an individual basis.
