RESUMEN
BACKGROUND: Severe dysphagia poses a significant challenge for clinicians regarding feeding tube choices, practices, and timing due to a lack of evidence-based guidance. OBJECTIVES: To assess national clinical practices and opinions on gastrostomy use in patients with atypical parkinsonian syndromes (APS) across the UK. METHODS: Online survey was administered to clinicians and allied health professionals regarding availability of services, current use, perceived advantages, and problems associated with gastrostomy insertion. RESULTS: We received responses from 47 respondents across 12 UK centers, including 44 clinicians specialized in APS. Consensus was observed regarding primary indications for gastrostomy insertion and circumstances justifying avoidance of the procedure. Limitations in recommending gastrostomy due to insufficient evidence on safety and outcomes, survival and quality of life were identified. Widespread agreement on delays in gastrostomy discussions was highlighted as a challenge in optimizing patient care, together with variability in current practices and concerns over the lack of a standardized gastrostomy pathway, emphasizing the need for further research to address existing evidence gaps. CONCLUSION: This multi-center survey highlights agreement among clinicians on key aspects of indication, challenges, and limitations such as delayed decision-making and the absence of standardized pathways regarding the timing, method, and overall approach to gastrostomy insertion in APS. This study identified next steps to facilitate a more structured approach to future research toward a consensus on best practices for gastrostomy in APS. Addressing these challenges is crucial for enhancing patient outcomes and overall care quality in APS.
RESUMEN
To review the assessment methods of dysphagia as a criterion for the decision-making process for Percutaneous Endoscopic Gastrostomy (PEG) placement in patients with Amyotrophic Lateral Sclerosis (ALS). Systematic review. A search was conducted in three databases (EMBASE, CINAHL, PUBMED) in December 2022 and updated in July 2023. Two reviewers independently screened, selected, and extracted data. Study quality was appraised using the Joanna Briggs Institute Critical Appraisal Tools. Systematic review registration number in the International Prospective Register of Systematic Reviews (PROSPERO): CRD42022385461. The searches identified 240 records. The 10 eligible studies included 2 case reports, 4 retrospective studies, 3 prospective studies, and 1 cohort observational study. Study quality was low, with most studies having moderate to high risk of bias. Dysphagia is a common criterion for decision-making. Dysphagia assessment is usually in the form of either self-reports, objective instrumental assessments, or both. Dysphagia is a common criterion for the decision-making process, yet is missing in clinical guidelines. Establishing the optimal means of dysphagia assessment is important for timely decision-making procedures, so that life-threatening consequences of dysphagia are minimized.
RESUMEN
After a stroke, most patients have dysphagia, which can lead to aspiration pneumonia, malnutrition, and adverse functional outcomes. Protective interventions aimed at reducing these complications remain the cornerstone of treatment. Dietary adjustments and oral hygiene help mitigate the risk of aspiration pneumonia, and nutritional supplementation, including tube feeding, might be needed to prevent malnutrition. Rehabilitative interventions aim to enhance swallowing function, with different behavioural strategies showing promise in small studies. Investigations have explored the use of pharmaceutical agents such as capsaicin and other Transient-Receptor-Potential-Vanilloid-1 (TRPV-1) sensory receptor agonists, which alter sensory perception in the pharynx. Neurostimulation techniques, such as transcranial direct current stimulation, repetitive transcranial magnetic stimulation, and pharyngeal electrical stimulation, might promote neuroplasticity within the sensorimotor swallowing network. Further advancements in the understanding of central and peripheral sensorimotor mechanisms in patients with dysphagia after a stroke, and during their recovery, will contribute to optimising treatment protocols.

BACKGROUND: Multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS) show a high prevalence and rapid progression of dysphagia, which is associated with reduced survival. Despite this, the evidence base for gastrostomy is poor, and the optimal frequency and outcomes of this intervention are not known. We aimed to characterise the prevalence and outcomes of gastrostomy in patients with these three atypical parkinsonian disorders. METHOD: We analysed data from the natural history and longitudinal cohorts of the PROSPECT-M-UK study with up to 60 months of follow-up from baseline. Survival post-gastrostomy was analysed using Kaplan-Meier survival curves. RESULTS: In a total of 339 patients (mean age at symptom onset 63.3 years, mean symptom duration at baseline 4.6 years), dysphagia was present in >50% across all disease groups at baseline and showed rapid progression during follow-up. Gastrostomy was recorded as recommended in 44 (13%) and performed in 21 (6.2%; MSA 7, PSP 11, CBS 3) of the total study population. Median survival post-gastrostomy was 24 months compared with 12 months where gastrostomy was recommended but not done (p = 0.008). However, this was not significant when correcting for age and duration of symptoms at the time of procedure or recommendation. CONCLUSIONS: Gastrostomy was performed relatively infrequently in this cohort despite the high prevalence of dysphagia. Survival post-gastrostomy was longer than previously reported, but further data on other outcomes and clinician and patient perspectives would help to guide use of this intervention in MSA, PSP and CBS.

BACKGROUND: Above cuff vocalisation (ACV) involves the application of an external flow of air via the subglottic port of a tracheostomy. ACV can facilitate vocalisation and may improve swallowing and quality of life for patients with a tracheostomy. A recent systematic review highlighted the limited evidence available for the acceptability, effectiveness, safety or optimal implementation of ACV. AIMS: To explore the experience of healthcare professionals (HCPs) using ACV and their perceptions of best practice. METHODS AND PROCEDURES: Semi-structured interviews were conducted with a range of HCPs with experience using ACV. Topics included: experiences with ACV, management of ACV, opinions about ACV, impact of COVID-19, future directions for ACV and impact on length of stay. Interviews were conducted online from December 2020 to March 2022. Data were analysed using reflexive thematic analysis. OUTCOMES AND RESULTS: Twenty-four HCPs were interviewed from seven countries and five professional groups. Four interconnected themes were developed: (1) moral distress amplifying the need to fix patients; (2) subjectivity and uncertainty leading to variations in practice and purpose; (3) knowledge and experience leading to control and caution; and (4) worth a try or a last resort. Theme four contained three sub-themes: (a) part of the toolbox; (b) useful but limited tool; and (c) following the patient's lead. The moral distress experienced by HCPs and their essential 'need to fix' patients seems to underpin the varied opinions of ACV. These opinions appear to be formed primarily on the basis of experience, because of the underlying subjectivities and uncertainties. As knowledge and experience with ACV increased, and adverse events were experienced, most HCPs became more cautious in their approach to ACV. CONCLUSIONS AND IMPLICATIONS: More research is needed to reduce the subjectivities and uncertainties surrounding ACV. The implementation of standardised procedures, processes, and competencies may help to reduce the frequency of adverse events and support a more controlled approach. Widening the focus of the purpose of ACV to include swallowing may help to maximise the potential benefits. WHAT THIS PAPER ADDS: What is already known on the subject There is limited and low-quality evidence for above cuff vocalisation (ACV) and clinical application and practice varies substantially. However, the reasons for this variation in practice and healthcare professionals' (HCPs') opinions of ACV were unclear. What this study adds HCPs' experiences and opinions of ACV vary as a result of the uncertainty and subjectivity surrounding ACV compounded by their personal experiences with it. A need for caution also appears to emerge as HCPs become more familiar and experienced with using ACV. What are the clinical implications of this work? Implementing standardised procedures, safety processes and competencies may help to compensate for the uncertainty and subjectivity surrounding ACV and may reduce the frequency of adverse events. Widening the focus of purpose of ACV, including swallowing in addition to communication, may increase the number of potential candidates and increase the potential benefits of ACV. Using multidisciplinary team (MDT) simulation training for ACV competency development might help to improve MDT working and ACV implementation.
RESUMEN
Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor and nonmotor impairment with various implications on patients' quality of life. Since currently available therapies are only symptomatic, identifying individuals with prodromal, preclinical, or early-stage PD is crucial, as they would be ideal candidates for future disease-modifying therapies. Our analysis aims to develop a robust model for accurate PD detection using accelerometer data collected from PD and non-PD individuals with mild or no tremor during phone conversations. An open-access dataset comprising accelerometer recordings from 22 PD patients and 11 healthy controls (HCs) was utilized. The data were preprocessed to extract relevant time-, frequency-, and energy-related features, and a bidirectional long short-term memory (Bi-LSTM) model with attention mechanism was employed for classification. The performance of the model was evaluated using fivefold cross-validation, and metrics of accuracy, precision, recall, specificity, and f1-score were computed. The proposed model demonstrated high accuracy (98%), precision (99%), recall (98%), specificity (96%), and f1-score (98%) in accurately distinguishing PD patients from HCs. Our findings indicate that the proposed model outperforms existing approaches and holds promise for detection of PD with subtle symptoms, like tremor, in the wild. Such symptoms can present in the early or even prodromal stage of the disease, and appropriate mobile-based applications may be a practical tool in real-life settings to alert individuals at risk to seek medical assistance or give patients feedback in monitoring their symptoms.

Dysphagia is a major complication following an acute stroke that affects the majority of patients. Clinically, dysphagia after stroke is associated with increased risk of aspiration pneumonia, malnutrition, mortality, and other adverse functional outcomes. Pathophysiologically, dysphagia after stroke is caused by disruption of an extensive cortical and subcortical swallowing network. The screening of patients for dysphagia after stroke should be provided as soon as possible, starting with simple water-swallowing tests at the bedside or more elaborate multi-consistency protocols. Subsequently, a more detailed examination, ideally with instrumental diagnostics such as flexible endoscopic evaluation of swallowing or video fluoroscopy is indicated in some patients. Emerging diagnostic procedures, technical innovations in assessment tools, and digitalisation will improve diagnostic accuracy in the future. Advances in the diagnosis of dysphagia after stroke will enable management based on individual patterns of dysfunction and predisposing risk factors for complications. Progess in dysphagia rehabilitation are essential to reduce mortality and improve patients' quality of life after a stroke.

OBJECTIVES: Previous research has shown that critical periods of feeding skills development exist and feeding problems can arise in children due to delays in attaining feeding developmental milestones. This study aims to delineate the transitional process of feeding development in healthy children and children with gastrointestinal diseases (GIDs) and to examine the relationship between feeding milestones and the appearance of later feeding problems. METHODS: A cross-sectional case-control study among 711 healthy Greek children and 119 children with GID, aged 2-7 years. Parents completed the Greek version of the Behavioral Pediatrics Feeding Assessment Scale and "self-reported" questionnaires assessing child's feeding history. RESULTS: Differences in feeding behavior of preschoolers between the 2 groups were found concerning the time of introduction of complementary (pureed), lumpy, and table foods as well as finger feeding and regular cup-drinking. Age-specific milestones as proposed by guidelines were not reached. Late introduction of complementary and lumpy foods (>6 months and >9 months, respectively) as well as finger feeding (>9 months) were predictive of more problematic feeding behaviors later on. CONCLUSIONS: The trajectory of feeding development, including less studied feeding milestones, both in healthy children and children with GIDs, indicates that there are discrepancies between current feeding practices and infant feeding guidelines, and a tendency to delay the acquisition of all assessed feeding milestones.

Introduction: Post-extubation dysphagia (PED) can have serious consequences for critically unwell patients. COVID-19 has resulted in an increasing need for a PED screen in order to effectively identify patients and mitigate risk, whilst balancing under-resourced services. Online training provides the advantage of reducing time pressures on staff and supporting social distancing. This project aimed to adapt the Leeds Post-Extubation Dysphagia Screen (L-PEDS) and the associated training package to be more suitable and effective for use during COVID-19 pandemic. Methods: The screen was modified to a digital format with additional guidance for users. The training package was shortened and converted to an online package while keeping the interactive mode of training. Results: Preliminary results of 14 staff members indicate that the median confidence levels for screening patients for PED improved from 5 to 8 (on a scale of 0 to 10) after completing the L-PEDS-COVID training package. Likewise, knowledge of PED improved from a median of 4 to 8 (on a scale of 0 to 10). Training quality was rated at a median of 8 on a scale of 0 to 10 (0 being very poor; 10 being very good). Conclusions: Preliminary evidence demonstrated increased knowledge of PED and confidence in screening. The development of an adapted version of the L-PEDS and online training package may allow easier implementation of post-extubation dysphagia screening. This could help to compensate for insufficient speech and language therapy critical care staffing, assist in identifying patients at risk and improve outcomes by enabling earlier and safe resumption of oral intake.
RESUMEN
Introduction: Dysphagia often occurs during Parkinson's disease (PD) and can have severe consequences. Recently, neuromodulatory techniques have been used to treat neurogenic dysphagia. Here we aimed to compare the neurophysiological and swallowing effects of three different types of neurostimulation, 5 Hertz (Hz) repetitive transcranial magnetic stimulation (rTMS), 1 Hz rTMS and pharyngeal electrical stimulation (PES) in patients with PD. Method: 12 PD patients with dysphagia were randomised to receive either 5 Hz rTMS, 1 Hz rTMS, or PES. In a cross-over design, patients were assigned to one intervention and received both real and sham stimulation. Patients received a baseline videofluoroscopic (VFS) assessment of their swallowing, enabling penetration aspiration scores (PAS) to be calculated for: thin fluids, paste, solids and cup drinking. Swallowing timing measurements were also performed on thin fluid swallows only. They then had baseline recordings of motor evoked potentials (MEPs) from both pharyngeal and (as a control) abductor pollicis brevis (APB) cortical areas using single-pulse TMS. Subsequently, the intervention was administered and post interventional TMS recordings were taken at 0 and 30 minutes followed by a repeat VFS within 60 minutes of intervention. Results: All interventions were well tolerated. Due to lower than expected recruitment, statistical analysis of the data was not undertaken. However, with respect to PAS swallowing timings and MEP amplitudes, there was small but visible difference in the outcomes between active and sham. Conclusion: PES, 5 Hz rTMS and 1 Hz rTMS are tolerable interventions in PD related dysphagia. Due to small patient numbers no definitive conclusions could be drawn from the data with respect to individual interventions improving swallowing function and comparative effectiveness between interventions. Larger future studies are needed to further explore the efficacy of these neuromodulatory treatments in Parkinson's Disease associated dysphagia.
RESUMEN
PURPOSE: Information on reliability of outcome measures used to assess the effectiveness of interventions in dysphagia rehabilitation is lacking, particularly when used by different research groups. Here, we report on reliability of the penetration-aspiration scale (PAS) and temporal and clearance measures, determined using videofluoroscopy. METHOD: Secondary analysis used videofluoroscopies from the Swallowing Treatment using Electrical Pharyngeal Stimulation trial in subacute stroke. PAS scores (719 scores from 18 participants) were evaluated and compared to the original PAS scores from the trial. Five conditions were assessed, including reliability for every swallow and overall mean of the worst PAS score. Operational rules for assessing temporal and clearance measures were also developed using the same data, and reliability of these rules was assessed. Reliability of component-level and derivative-level scores was assessed using the intraclass correlation coefficient (ICC) and weighted kappa. RESULTS: Image quality was variable. Interrater reliability for the overall mean of the worst PAS score was excellent (ICC = .914, 95% confidence interval [CI] [.853, .951]) but moderate for every swallow in the bolus (ICC = .743, 95% CI [.708, .775]). Intrarater reliability for PAS was excellent (all conditions). Excellent reliability (both inter- and intrarater > .90) was seen for temporal measures of stage transition duration (ICC = .998, 95% CI [.993, .999] and ICC = .995, 95% CI [.987, .998], respectively) as well as initiation of laryngeal closure and pharyngeal transit time and all individual swallow events. Strong scores were obtained for some clearance measures; others were moderate or weak. CONCLUSIONS: Interrater reliability for PAS is acceptable but depends on how the PAS scores are handled in the analysis. Interrater reliability for most temporal measures was high, although some measures required additional training. No clearance measures had excellent reliability.

OBJECTIVE: To conduct an international survey to investigate the use of above cuff vocalization (ACV) and how practice and opinion differs. DESIGN: Observational, cross-sectional online survey. SETTING: Critical care, acute, rehabilitation, long-term care, and community. PARTICIPANTS: Health care professionals involved in tracheostomy care or weaning (N=243). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Tracheostomy management, prevalence, personal experiences and opinions, and barriers to use. Quantitative data were reported descriptively, and content analysis was conducted with qualitative data. RESULTS: The survey was completed by 243 health care professionals from 9 professional groups and 25 countries, with most responses from the United Kingdom (54%) and speech and language therapists (55%). ACV was used in 39% of services (n=93). Sixty percent (n=50/83) of health care professionals with direct experience of ACV had used it with <10 people. Implementation of ACV varied widely concerning procedures, contraindications, safety processes, professionals involved, competencies, staff training, delivery, and outcome measures. The top benefits were communication (n=76/93; 82%), mood (n=62/93; 67%), and laryngeal sensation (n=49/93; 53%). Complications included discomfort (n=54/93; 58%) and strained vocal quality (n=39/93; 42%). Barriers to ACV implementation included lack of knowledgeable staff (n=92/238; 39%) and lack of access to training (n=73/238; 31%). CONCLUSIONS: ACV uptake varies internationally with no standardized approach to ACV delivery. Diversity of opinions on approaches and benefits exist. Serious complications are infrequent, but minor complications are common. Future research is needed to establish optimal ACV implementation to maximize benefits and minimize risks.

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative disorder characterized by a combination of motor and non-motor dysfunction. Dysphagia is a common symptom in PD, though it is still too frequently underdiagnosed. Consensus is lacking on screening, diagnosis, and prognosis of dysphagia in PD. OBJECTIVE: To systematically review the literature and to define consensus statements on the screening and the diagnosis of dysphagia in PD, as well as on the impact of dysphagia on the prognosis and quality of life (QoL) of PD patients. METHODS: A multinational group of experts in the field of neurogenic dysphagia and/or PD conducted a systematic revision of the literature published since January 1990 to February 2021 and reported the results according to PRISMA guidelines. The output of the research was then analyzed and discussed in a consensus conference convened in Pavia, Italy, where the consensus statements were drafted. The final version of statements was subsequently achieved by e-mail consensus. RESULTS: Eighty-five papers were used to inform the Panel's statements even though most of them were of Class IV quality. The statements tackled four main areas: (1) screening of dysphagia: timing and tools; (2) diagnosis of dysphagia: clinical and instrumental detection, severity assessment; (3) dysphagia and QoL: impact and assessment; (4) prognostic value of dysphagia; impact on the outcome and role of associated conditions. CONCLUSIONS: The statements elaborated by the Consensus Panel provide a framework to guide the neurologist in the timely detection and accurate diagnosis of dysphagia in PD.

BACKGROUND: Previous reports suggested the potential benefit of chemesthesis in the form of carbonated water (CW) integrated within dysphagia rehabilitation protocols. Here, we examined the effects of CW within a repeated swallowing protocol following focal suppression to pharyngeal cortical representation as a prelude to its application in dysphagic patients. METHODS: Fourteen healthy volunteers participated in a 3-arm study. Each participant underwent baseline corticobulbar pharyngeal and thenar motor-evoked potential (MEP) measurements with Transcranial Magnetic Stimulation (TMS). Subjects were then conditioned with 1Hz repetitive (r)TMS to induce focal unilateral suppression of the corticopharyngeal hotspot before randomization to each of three arms with 40 swallows of CW, non-CW and saliva swallowing on separate days. Corticobulbar and thenar MEPs were collected for up to 1 h and analyzed using repeated measures (rm)ANOVA. RESULTS: A 2-way rmANOVA for Intervention x Time showed a significant effect of Intervention (F(1,13) = 7.519, p = 0.017) in both ipsi- and contra-lesional corticopharyngeal projections. Carbonation showed superiority in facilitating change by increasing pharyngeal cortical MEPs compared to non-CW (z = -3.05, p = 0.002) and saliva swallowing (z = -2.6, p = 0.008). No change in thenar representation (control) was observed nor in MEP latencies from both pharyngeal and thenar musculature. CONCLUSIONS: We conclude that interventional paradigms with CW have the capacity to reverse the effects of a focal suppression with 1Hz rTMS more strongly than non-CW or saliva swallowing alone, producing site specific bi-hemispheric changes in corticopharyngeal excitability. Our data suggest that carbonation produces the effects through a mainly cortical mechanism.

OBJECTIVE: Evaluate the relationship between falls, freezing of gait, and swallowing disturbance in Parkinson's disease (PD). BACKGROUND: Dysphagia is a common symptom in PD, and is often thought of as an axial feature along with falls and gait disturbance. It is of interest to examine the relationship between these symptoms in PD, given the possibility of shared pathophysiology due to non-dopaminergic and extranigral dysfunction. METHODS: We recruited 29 consecutive non-demented patients with idiopathic PD and at least one clinically determined impairment in swallowing, falls, or freezing of gait. Swallow dysfunction was assessed using the Swallowing Disturbance Questionnaire (SDQ). The Falls Efficacy Scale and Freezing-of-gait questionnaire were recorded. Correlation analysis and multiple regression were used to determine the relationship between swallow and gait disturbance. RESULTS: Total SDQ score correlated strongly with the falls efficacy scale (Spearman's rho = 0.594; P = 0.001), but not with the freezing-of-gait score. Linear regression controlling for other factors associated with dysphagia identified falls efficacy score as a significant predictor of swallow dysfunction. CONCLUSIONS: The severity of dysphagia in PD is closely related to severity of falls, but not gait freezing. This may be helpful to more precisely determine the anatomical substrate of levodopa-resistant axial symptoms in PD and provide clues to further management.

OBJECTIVES/HYPOTHESIS: To determine how above cuff vocalization (ACV) is implemented in clinical practice, to identify what evidence exists on the effectiveness and safety of ACV, and to evaluate the acceptability of ACV. STUDY DESIGN: Systematic review. METHODS: A literature search was conducted in eight databases (MEDLINE, Embase, AMED, CINAHL, Cochrane Library, PsycINFO, Scopus, and Web of Science) in May 2019 and updated in June 2020. Two reviewers independently screened, selected, and extracted data. Study quality was appraised using the Joanna Briggs Institute Critical Appraisal Tools and a narrative synthesis was conducted. Systematic review registration number: CRD42019133942. RESULTS: The searches identified 1327 records. The 13 eligible studies included four case studies, three case series, four observational studies without a control group, one quasi-experimental study, and one randomized controlled trial. Study quality was low, with most studies having high risk of bias. There was a high level of heterogeneity in study design and outcome measures used. Detailed information on ACV application and dose-delivered was lacking in 12 studies. Positive effects were reported for communication (n = 7), swallowing (n = 4), cough response (n = 2), and quality-of-life (n = 2), but with inconsistent use of objective outcome measures. There is limited quantitative or qualitative evidence for acceptability. Adverse events and complications were reported in nine studies, and four highlighted the importance of involving an experienced speech and language therapist. CONCLUSIONS: There is limited evidence for the acceptability, effectiveness, safety, or optimal implementation of ACV. The evidence is insufficient to provide recommendations regarding optimal intervention delivery. Future research should ensure detailed recording of ACV delivery and utilize a core outcome set.

Post-stroke dysphagia (PSD) is present in more than 50% of acute stroke patients, increases the risk of complications, in particular aspiration pneumonia, malnutrition and dehydration, and is linked to poor outcome and mortality. The aim of this guideline is to assist all members of the multidisciplinary team in their management of patients with PSD. These guidelines were developed based on the European Stroke Organisation (ESO) standard operating procedure and followed the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. An interdisciplinary working group identified 20 relevant questions, performed systematic reviews and meta-analyses of the literature, assessed the quality of the available evidence and wrote evidence-based recommendations. Expert opinion was provided if not enough evidence was available to provide recommendations based on the GRADE approach. We found moderate quality of evidence to recommend dysphagia screening in all stroke patients to prevent post-stroke pneumonia and to early mortality and low quality of evidence to suggest dysphagia assessment in stroke patients having been identified at being at risk of PSD. We found low to moderate quality of evidence for a variety of treatment options to improve swallowing physiology and swallowing safety. These options include dietary interventions, behavioural swallowing treatment including acupuncture, nutritional interventions, oral health care, different pharmacological agents and different types of neurostimulation treatment. Some of the studied interventions also had an impact on other clinical endpoints such as feedings status or pneumonia. Overall, further randomized trials are needed to improve the quality of evidence for the treatment of PSD.
RESUMEN
BACKGROUND: Dysphagia is common in Parkinson's disease (PD). The effects of antiparkinsonian drugs on dysphagia are controversial. Several treatments for dysphagia are available but there is no consensus on their efficacy in PD. OBJECTIVE: To conduct a systematic review of the literature and to define consensus statements on the treatment of dysphagia in PD and related nutritional management. METHODS: A multinational group of experts in the field of neurogenic dysphagia and/or Parkinson's disease conducted a systematic evaluation of the literature and reported the results according to PRISMA guidelines. The evidence from the retrieved studies was analyzed and discussed in a consensus conference organized in Pavia, Italy, and the consensus statements were drafted. The final version of statements was subsequently achieved by e-mail consensus. RESULTS: The literature review retrieved 64 papers on treatment and nutrition of patients with PD and dysphagia, mainly of Class IV quality. Based on the literature and expert opinion in cases where the evidence was limited or lacking, 26 statements were developed. CONCLUSIONS: The statements developed by the Consensus panel provide a guidance for a multi-disciplinary treatment of dysphagia in patients with PD, involving neurologists, otorhinolaryngologists, gastroenterologists, phoniatricians, speech-language pathologists, dieticians, and clinical nutritionists.
