Background: Cognitive impairment is common in Parkinson's disease (PD), but care needs and resource use for those with significant cognitive impairment are not well established. Methods: 675 participants with PD from the international Care of Late-Stage Parkinsonism (CLaSP) study were grouped into those without (n = 333, 49%) and with cognitive impairment (MMSE < 24/30 or diagnosis of dementia or Mild Cognitive Impairment; n = 342, 51%) and their clinical features, care needs and healthcare utilisation compared. The relationship between cognition and healthcare consultations was investigated through logistic regression. Results: Cognitive impairment was associated with more motor and non-motor symptoms, less antiparkinsonian but higher rates of dementia and antipsychotic medication, worse subjective health status and greater caregiver burden. A considerable proportion did not have a pre-established cognitive diagnosis. Care needs were high across the whole sample but higher in the cognitive impairment group. Home care and care home use was higher in the cognitive impairment group. However, use of healthcare consultations was similar between the groups and significantly fewer participants with cognitive impairment had had recent PD Nurse consultations. Worse cognitive impairment was associated with lower frequency of recent PD nurse and multidisciplinary therapy consultation (physiotherapy, massage, occupational therapy, speech training and general nursing). Conclusions: Those with cognitive impairment have more severe PD, higher care needs and greater social care utilisation than those with normal cognition, yet use of health care services is similar or less. Cognitive impairment appears to be a barrier to PD nurse and multidisciplinary therapy consultations. This challenges current models of care: alternative models of care may be required to serve this population. Plain Language Summary: Parkinson's disease is a long-term progressive health condition. Over time, many people with Parkinson's develop problems with thinking and memory, called cognitive impairment. This can negatively impact the daily lives of the person with Parkinson's and their caregiver. It is also thought to be a barrier to accessing healthcare. How people with Parkinson's who have cognitive impairment use healthcare and detail of their care needs is not well known. We analysed data from a large sample of people with advanced Parkinson's from six European countries to investigate their symptoms, care needs and healthcare use. We compared those with cognitive impairment to (342 people) to those without cognitive impairment (333 people). We found that those with cognitive impairment had more severe Parkinson's across a range of symptoms compared to those without cognitive impairment. They also had more care needs, reported their health status to be worse, and their caregivers experienced greater strain from caring. Whilst use of other healthcare services was similar between the two groups, those with cognitive impairment were less likely to have recently seen a Parkinson's nurse than those without cognitive impairment. Further analysis showed an association between cognitive impairment and not having seen a Parkinson's nurse or therapist recently, taking psychiatric symptoms, functional disability and care home residence into account. Therapists included were physiotherapy, massage, occupational therapy, speech training and general nursing. These findings highlight unmet need. We suggest that healthcare should be more targeted to help this group of people, given their higher care needs. [ABSTRACT FROM AUTHOR]

Reduced spontaneous blinking is a recognized Parkinson's disease (PD) feature. In contrast, voluntary blinking has been less studied and might serve as a measurable marker of facial bradykinesia. We tested 31 PD patients and 31 controls. Participants were filmed during conversation and a rapid blinking task. Both tasks were videorecorded to count the number of blinks per second. PD patients had lower blink rates. Rapid blinking accurately discriminated between groups with 77% sensitivity and 71% specificity. To conclude, rapid blinking may be a simple and quantifiable task of facial bradykinesia. Plain Language Summary: Decreased blinking without conscious effort is a well-known characteristic of Parkinson's disease (PD). However, voluntary blinking, which is blinking on purpose, has not been studied as much and could be a sign of slower facial movements. We studied a group of people with PD and another one without the disease. We recorded videos of them talking and doing a task where they blinked quickly. Then, we counted how many times they blinked per second in each video. We found that people with PD blinked less often. The rapid blinking task accurately distinguished between those with PD and those without it, being correct about 77% of the time for spotting PD and 71% for spotting non-PD. In conclusion, the rapid blinking task could be a simple and measurable way to identify slower facial movements in PD. [ABSTRACT FROM AUTHOR]

Background: A history of anxiety is more common in people with Parkinson's disease (PD). The prospective risk of PD in those newly presenting with anxiety and factors that increase the risk of PD in patients with anxiety have not been investigated. Aim: To investigate the incidence of PD in people with anxiety aged ≥50 years and clinical features associated with later diagnosis of PD in people with anxiety. Design and setting: A retrospective cohort study using UK primary care data between 2008 and 2018, assessing patients with new-onset anxiety aged ≥50 years. Method: Weibull survival regression models were fitted and hazard ratios (HRs) for modelling time-to-PD was estimated in those with and without anxiety, and when determining the risk of developing PD in those with anxiety. Results were adjusted for sociodemographic and lifestyle factors, and relevant physical and mental health conditions. Results: The risk of PD increased two-fold compared with the non-anxiety group after adjustment for age, sex, social deprivation, lifestyle factors, severe mental illness, head trauma, and dementia (HR 2.1, 95% confidence interval = 1.9 to 2.4). In those with anxiety, the presence of depression, hypotension, tremor, rigidity, balance impairment, constipation, sleep disturbance, fatigue, and cognitive impairment were associated with an increased risk of developing PD. Conclusion: The risk of developing PD was at least doubled in people with anxiety compared with those without. The clinical features of those who developed PD can help identify patients presenting with anxiety who are in the prodromal phase of PD. [ABSTRACT FROM AUTHOR]

Introduction: People with Parkinson's disease (PD) often present with disabling neuropsychiatric symptoms. Compassionate mind training (CMT) is a psychological approach effective in reducing stress and promoting psychological well‐being. Heart rate variability (HRV), a measure reflecting sympathovagal balance, has been associated with psychological well‐being and a compassionate attitude. Aim: To assess the feasibility and effectiveness of CMT in enhancing the quality of life and psychological well‐being in PD patients. Additionally, we evaluated HRV as a physiomarker for assessing the CMT outcomes. Methods: Twenty‐four PD patients participated in the study. A 6‐week online CMT intervention was delivered on a weekly basis. At baseline and post‐intervention patients completed questionnaires assessing depression, anxiety and quality of life. In a subsample of 11 patients, HRV was measured at baseline and post‐intervention in three conditions: at rest, during stress and after 3 min of deep breathing. Results: The attendance rate was 94.3%. Quality of life and perceived stigma improved post‐intervention as compared with baseline (p = 0.02 and p = 0.03 for PD Questionnaire‐39 total score and Stigma subscore, respectively). After CMT, patients presented better physiological regulation to stress, as measured by higher HRV as compared with baseline (p = 0.005). Notably, patients who were more resilient to stress at baseline (less decrease in HRV during stress) experienced a more substantial reduction in anxiety and depression following CMT. Conclusions: CMT is feasible and can improve quality of life and stigma in PD patients. HRV emerges as a promising physiomarker for predicting and measuring the outcomes of psychological interventions in PD. [ABSTRACT FROM AUTHOR]

BackgroundPeople with Parkinson's disease (PD) who develop visuo-perceptual deficits are at higher risk of dementia, but we lack tests that detect subtle visuo-perceptual deficits and can be performed by untrained personnel. Hallucinations are associated with cognitive impairment and typically involve perception of complex objects. Changes in object perception may therefore be a sensitive marker of visuo-perceptual deficits in PD.ObjectiveWe developed an online platform to test visuo-perceptual function. We hypothesised that (1) visuo-perceptual deficits in PD could be detected using online tests, (2) object perception would be preferentially affected, and (3) these deficits would be caused by changes in perception rather than response bias.MethodsWe assessed 91 people with PD and 275 controls. Performance was compared using classical frequentist statistics. We then fitted a hierarchical Bayesian signal detection theory model to a subset of tasks.ResultsPeople with PD were worse than controls at object recognition, showing no deficits in other visuo-perceptual tests. Specifically, they were worse at identifying skewed images (P

Background: Cognitive impairment is common in Parkinson's disease and is associated with poorer quality of life and increased caregiver distress, but little qualitative information is available on lived experiences of people with Parkinson's who also have cognitive impairment. Objectives: The aim of this study was to explore the challenges of cognitive impairment in Parkinson's, triangulating the perspectives of people with Parkinson's, caregivers and healthcare professionals. Methods: Semistructured interviews were conducted with 11 people with Parkinson's and cognitive impairment, 10 family caregivers and 27 healthcare professionals, using purposive sampling in the United Kingdom (2019–2021). Cognitive impairment was identified by healthcare professionals and required subjective symptoms. Relevant cognitive diagnoses were recorded. Interviews were audio‐recorded, transcribed and analysed using reflexive thematic analysis. Results: An overarching concept of the compound impact of cognitive and physical decline was developed, with six themes. Four themes describe the experience of living with cognitive impairment in Parkinson's: (1) Challenges in Daily Activities, (2) Psychological Impact and (3) Evolving Communication Difficulties together contributing to (4) Social Shift, encompassing a reduction in wider social activities but intensification of close relationships with increased dependence. A fifth theme (5) Living Well describes positive influences on these experiences, encompassing intrinsic motivation, self‐management strategies and supportive relationships. Furthermore, underlying and shaping the whole experience was the sixth theme: (6) Preconceptions about Cognitive Impairment, describing fear and denial of symptoms and poor understanding of the nature of cognitive impairment in Parkinson's, with differences to other dementia pathologies. Conclusions: Cognitive impairment superimposed on the existing challenges of Parkinson's has a multifaceted impact and makes living with the condition arduous. Increased understanding of the experiences of this group and employing the identified facilitators for living well may be able to improve patient and caregiver experiences. Patient or Public Contribution: Two people with Parkinson's and cognitive impairment and three caregivers contributed to the study. Between them they contributed throughout the entirety of the project, giving input at conceptualisation as well as advice and review of interview questions, participant information leaflets, recruitment, interpretation of findings and summaries of the project.

Background: People with Parkinson's disease has significant and increasing physical, psychosocial and spiritual needs, as well as problems with coordination and continuity of care. Despite the benefits that palliative care could offer, there is no consensus on how it should be delivered. Aim: The aim of this study is to provide a pragmatic overview of the evidence to make clinical recommendations to improve palliative care for people with Parkinson's disease and their caregivers. Design: A systematic review method was adopted to determine the strength of evidence, supported by feedback from an expert panel, to generate the 'do', 'do not do' and 'do not know' recommendations for palliative care. Data sources: Searches were conducted via OVID to access CINAHL, MEDLINE, EMBASE and the Cochrane Library from 01/01/2006 to 31/05/2021. An additional search was conducted in December 2022. The search was limited to articles that included empirical studies of approaches to enabling palliative care. Results: A total of 62 studies met inclusion criteria. There is evidence that education about palliative care and movement disorders is essential. palliative care should be multi-disciplinary, individualised and coordinated. Proactive involvement and support of caregivers throughout the illness is recommended. Limited data provide referral indicators for palliative care integration. Discussions about advance care planning should be held early. Conclusions: Consideration of palliative care integration based on symptom burden and personal preferences, coordination and continuity of care are needed to maintain the quality of life of people with Parkinson's disease and their caregivers.
