Impact of advanced Parkinson's disease on caregivers: an international real-world study.

BACKGROUND: Caring for a partner or family member with Parkinson's disease (PD) negatively affects the caregiver's own physical and emotional well-being, especially those caring for people with advanced PD (APD). This study was designed to examine the impact of APD on caregiver perceived burden, quality of life (QoL), and health status. METHODS: Dyads of people with PD and their primary caregivers were identified from the Adelphi Parkinson's Disease Specific Program (DSP™) using real-world data from the United States, Japan and five European countries. Questionnaires were used to capture measures of clinical burden (people with PD) and caregiver burden (caregivers). RESULTS: Data from 721 patient-caregiver dyads in seven countries were captured. Caregivers had a mean age 62.6 years, 71.6% were female, and 70.4% were a spouse. Caregivers for people with APD had a greater perceived burden, were more likely to take medication and had lower caregiver treatment satisfaction than those caring for people with early or intermediate PD; similar findings were observed for caregivers of people with intermediate versus early PD. Caregivers for people with intermediate PD were also less likely to be employed than those with early PD (25.3% vs 42.4%) and spent more time caring (6.6 vs 3.2 h/day). CONCLUSIONS: This real-world study demonstrates that caregivers of people with APD experience a greater burden than those caring for people with early PD. This highlights the importance of including caregiver-centric measures in future studies, and emphasizes the need for implementing treatments that reduce caregiver burden in APD.

Neurological and Neuropsychiatric Impacts of COVID-19 Pandemic.

BACKGROUND: Albeit primarily a disease of respiratory tract, the 2019 coronavirus infectious disease (COVID-19) has been found to have causal association with a plethora of neurological, neuropsychiatric and psychological effects. This review aims to analyze them with a discussion of evolving therapeutic recommendations. METHODS: PubMed and Google Scholar were searched from 1 January 2020 to 30 May 2020 with the following key terms: "COVID-19", "SARS-CoV-2", "pandemic", "neuro-COVID", "stroke-COVID", "epilepsy-COVID", "COVID-encephalopathy", "SARS-CoV-2-encephalitis", "SARS-CoV-2-rhabdomyolysis", "COVID-demyelinating disease", "neurological manifestations", "psychosocial manifestations", "treatment recommendations", "COVID-19 and therapeutic changes", "psychiatry", "marginalised", "telemedicine", "mental health", "quarantine", "infodemic" and "social media". A few newspaper reports related to COVID-19 and psychosocial impacts have also been added as per context. RESULTS: Neurological and neuropsychiatric manifestations of COVID-19 are abundant. Clinical features of both central and peripheral nervous system involvement are evident. These have been categorically analyzed briefly with literature support. Most of the psychological effects are secondary to pandemic-associated regulatory, socioeconomic and psychosocial changes. CONCLUSION: Neurological and neuropsychiatric manifestations of this disease are only beginning to unravel. This demands a wide index of suspicion for prompt diagnosis of SARS-CoV-2 to prevent further complications and mortality.

Les impacts neurologiques et neuropsychiatriques d'une infection à la COVID-19. CONTEXTE: Bien qu'il s'agisse principalement d'une maladie des voies respiratoires, la maladie infectieuse à coronavirus apparue en 2019 (COVID-19) s'est avérée avoir un lien de causalité avec une pléthore d'impacts d'ordre neurologique, neuropsychiatrique et psychologique. Cette étude entend donc analyser ces impacts tout en discutant l'évolution des recommandations thérapeutiques se rapportant à cette maladie. MÉTHODES: Les bases de données PubMed et Google Scholar ont été interrogées entre les 1er janvier et 30 mai 2020. Les termes clés suivants ont été utilisés : « COVID-19 ¼, « SRAS ­ CoV-2 ¼, « Pandémie ¼, « Neuro ­ COVID ¼, « AVC ­ COVID ¼, « Épilepsie ­ COVID ¼, « COVID ­ encéphalopathie ¼, « SRAS ­ CoV-2 ­ encéphalite ¼, « SRAS ­ CoV-2 ­ rhabdomyolyse ¼, « COVID ­ maladie démyélinisante ¼, « Manifestations neurologiques ¼, « Manifestations psychosociales ¼, « Recommandations thérapeutiques ¼, « COVID-19 et changement thérapeutiques ¼, « Psychiatrie ¼, « Marginalisés ¼, « Télémédecine ¼, « Santé mentale ¼, « Quarantaine ¼, « Infodémique ¼ et « Médias sociaux ¼. De plus, quelques articles de journaux relatifs à la pandémie de COVID-19 et à ses impacts psychosociaux ont également été ajoutés en fonction du contexte. RÉSULTATS: Il appert que les manifestations neurologiques et neuropsychiatriques des infections à la COVID-19 sont nombreuses. Les caractéristiques cliniques d'une implication des systèmes nerveux central et périphérique sautent désormais aux yeux. Ces caractéristiques ont fait l'objet d'une brève analyse systématique à l'aide de publications scientifiques. En outre, la plupart des impacts d'ordre psychologique de cette pandémie se sont révélés moins apparents que les changements réglementaires, socioéconomiques et psychosociaux. CONCLUSION: Les manifestations neurologiques et neuropsychiatriques de cette maladie ne font que commencer à être élucidées. Cela exige donc une capacité accrue de vigilance en vue d'un diagnostic rapide, et ce, afin de prévenir des complications additionnelles et une mortalité accrue.

What are the modifiable factors of treatment burden and capacity among people with Parkinson's disease and their caregivers: A qualitative study.

BACKGROUND: People with long-term conditions must complete many healthcare tasks such as take medications, attend appointments, and change their lifestyle. This treatment burden and ability to manage it (capacity) is not well-researched in Parkinson's disease. OBJECTIVE: To explore and identify potentially modifiable factors contributing to treatment burden and capacity in people with Parkinson's disease and caregivers. METHODS: Semi-structured interviews with nine people with Parkinson's disease and eight caregivers recruited from Parkinson's disease clinics in England (ages 59-84 years, duration of Parkinson's disease diagnosis 1-17 years, Hoehn and Yahr (severity of Parkinson's disease) stages 1-4) were conducted. Interviews were recorded and analyzed thematically. RESULTS: Four themes of treatment burden with modifiable factors were identified: 1) Challenges with appointments and healthcare access: organizing appointments, seeking help and advice, interactions with healthcare professionals, and caregiver role during appointments; 2) Issues obtaining satisfactory information: sourcing and understanding information, and satisfaction with information provision; 3) Managing medications: getting prescriptions right, organizing polypharmacy, and autonomy to adjust treatments; and 4) Lifestyle changes: exercise, dietary changes, and financial expenses. Aspects of capacity included access to car and technology, health literacy, financial capacity, physical and mental ability, personal attributes and life circumstances, and support from social networks. CONCLUSIONS: There are potentially modifiable factors of treatment burden including addressing the frequency of appointments, improving healthcare interactions and continuity of care, improving health literacy and information provision, and reducing polypharmacy. Some changes could be implemented at individual and system levels to reduce treatment burden for people with Parkinson's and their caregivers. Recognition of these by healthcare professionals and adopting a patient-centered approach may improve health outcomes in Parkinson's disease.

Utilising telehealth to support exercise and physical activity in people with Parkinson disease: a program evaluation using mixed methods.

BACKGROUND: Physical activity and exercise play a key role in managing Parkinson disease. This study aimed to: 1) determine if physiotherapy supported by telehealth helped people with Parkinson disease (PwP) to adhere to a home-based exercise program and maintain their physical activity; and 2) understand their experiences of using telehealth during the COVID-19 pandemic. METHODS: A mixed methods program evaluation involving a retrospective file audit from a student-run physiotherapy clinic and semi-structured interviews exploring participants' experiences of telehealth. Ninety-six people with mild to moderate disease received home-based telehealth physiotherapy for 21 weeks. The primary outcome was adherence to the prescribed exercise program. Secondary outcomes were measures of physical activity. Interviews were conducted with 13 clients and seven students and analysed thematically. RESULTS: Adherence to the prescribed exercise program was high. The mean (SD) proportion of prescribed sessions completed was 108% (46%). On average clients spent 29 (12) minutes per session, and 101 (55) minutes per week exercising. Physical activity levels were maintained, with clients taking 11,226 (4,832) steps per day on entry to telehealth, and 11,305 (4,390) steps per day on exit from telehealth. The semi-structured interviews identified important features of a telehealth service required to support exercise; a flexible approach of clients and therapists, empowerment, feedback, a therapeutic relationship, and mode of delivery. CONCLUSIONS: PwP were able to continue exercising at home and maintain their physical activity when physiotherapy was provided via telehealth. The flexible approach of both the client and the service was imperative.

Links between COVID-19 and Parkinson's disease/Alzheimer's disease: reciprocal impacts, medical care strategies and underlying mechanisms.

The impact of coronavirus disease 2019 (COVID-19) pandemic on patients with neurodegenerative diseases and the specific neurological manifestations of COVID-19 have aroused great interest. However, there are still many issues of concern to be clarified. Therefore, we review the current literature on the complex relationship between COVID-19 and neurodegenerative diseases with an emphasis on Parkinson's disease (PD) and Alzheimer's disease (AD). We summarize the impact of COVID-19 infection on symptom severity, disease progression, and mortality rate of PD and AD, and discuss whether COVID-19 infection could trigger PD and AD. In addition, the susceptibility to and the prognosis of COVID-19 in PD patients and AD patients are also included. In order to achieve better management of PD and AD patients, modifications of care strategies, specific drug therapies, and vaccines during the pandemic are also listed. At last, mechanisms underlying the link of COVID-19 with PD and AD are reviewed.

When brain devices go wrong: a patient with a malfunctioning deep brain stimulator (DBS) presents to the emergency department.

A man in his 50s attended the emergency department with an acute deterioration in his Parkinson's symptoms, presenting with limb rigidity, widespread tremor, choreiform dyskinesia, dysarthria, intense sadness and a severe occipital headache. After excluding common differentials for sudden-onset parkinsonism (eg, infection, medication change), an error on the patient's deep brain stimulator was noted. The patient's symptoms only resolved once he was transferred to the specialist centre so that the programmer could reset the device settings. Due to COVID-19-related bed pressures on the ward, there was a delay in the patient receiving specialist attention-highlighting the need for non-specialist training in the emergency management of device errors.

A pilot study of a 12-week community-based boxing program for Parkinson's disease.

INTRODUCTION: Community-based exercise programs for Parkinson's disease (PD) have gained popularity. Our understanding of such programs on non-motor features is limited. We characterized the effect of a 12-week community-based boxing exercise program on motor and non-motor symptoms in people with Parkinson's disease (PwPD). METHODS: In this prospective observational study, PwPD underwent a 12-week community-based boxing program (2 sessions per week, for a total of 24 sessions). The following assessments were performed by a movement disorders neurologist at baseline and after completion of the program: MDS-Unified Parkinson's Disease Rating Scale part III (MDS-UPDRS III) in a modified version since assessments were performed virtually due to COVID-19 pandemic, MDS Non-Motor Rating Scale (MDS-NMS), Hamilton Depression Rating Scale (HDRS), Lilli Apathy Rating Scale (LARS), Parkinson's Disease Questionaire-39 (PDQ-39), and Schwab and England Activities of Daily Living scale (SE-ADL). Pre- and post-assessments were compared using Wilcoxon signed rank test; only participants who completed the program and both assessments were analyzed. RESULTS: A total of 14 PwPD agreed to be a part of the study and completed assessments. All participants were ambulatory and functionally independent at baseline. Total non-motor feature severity (MDS-NMS, p = 0.0031), depression (HDRS, p = 0.015), and motor features (MDS-UPDRS PART 3 modified, p = 0.023) all improved significantly after the intervention. Scales on apathy (LARS, p = 0.29), Parkinson's disease-specific health related quality (PDQ-39, p = 0.093), and activities of daily living (SE-ADL, p = 0.32) did not demonstrate significant change. CONCLUSION: PwPD who participated in a community-based, pilot boxing program showed improvements in motor exam and non-motor symptoms.

Moving online: Experiences and potential benefits of digital dance for older adults and people with Parkinson's disease.

BACKGROUND: Dance provides a range of beneficial effects for older adults including individuals with age-related neurological conditions such as Parkinson's disease (PD). The COVID-19 pandemic accelerated the development of at-home dance programs delivered digitally through live and pre-recorded media, but little is known about how participants may engage with and benefit from these resources. OBJECTIVE: This study explored experiences and potential benefits of digital dance participation among healthy older adults and people with PD. METHODS: An online survey consisting of fixed-choice and open questions was designed in collaboration with dance program providers and distributed between June and November 2020. RESULTS: Healthy older adults (N = 149) and people with PD (N = 178) participating in at-home dance programs reported frequent engagement and a range of benefits. People with PD reported greater levels of motor (e.g., ease of movement, balance) than non-motor (e.g., energy, confidence) outcomes, while healthy older adults reported similar numbers of motor and non-motor outcomes. Positive outcomes were associated with the use of movement imagery during dance in both groups, while singing was associated with benefits in people with PD and vocalising was associated with benefits in older adults. At-home dance resources were found to offer convenience and flexibility, but participants missed the interaction, support, and routine provided by in-person classes. The majority expressed a preference to continue with both digital and in-person participation in the future. Qualitative analysis of participants' comments further revealed that digital participation could help to maintain connection and well-being, as well as identifying further considerations for improving accessibility and facilitating digital engagement. CONCLUSIONS: At-home dance appears to be accessible, engaging, and potentially beneficial for older adults and people with PD, although barriers to participation should be addressed. Digital resources will be increasingly important to enable cost-effective, large-scale provision of home-based therapeutic activities.

Mind the gap: Inequalities in mental health care and lack of social support in Parkinson disease.

Inequalities in mental healthcare and lack of social support during the COVID-19 pandemic have lowered quality of life and increased overall burden of disease in people with Parkinson's (PWP). Although the pandemic has brought attention to these inequalities, they are long standing and will persist unless addressed. Lack of awareness of mental health issues is a major barrier and even when recognized disparities based on race, gender, and socioeconomic factors limit access to already scarce resources. Stigma regarding mental illness is highly prevalent and is a major barrier even when adequate care exists. Limited access to mental healthcare during the pandemic and in general increases the burden on caregivers and families. Historically, initiatives to improve mental healthcare for PWP focused on interventions designed for specialty and academic centers generally located in large metropolitan areas, which has created unintended geographic disparities in access. In order to address these issues this point of view suggests a community-based wellness model to extend the reach of mental healthcare resources for PWP.

Cognitive Digital Intervention for Older Patients with Parkinson's Disease during COVID-19: A Mixed-Method Pilot Study.

Mild cognitive impairment is frequent among people with Parkinson's disease. Cognitive training seems effective for cognitive status and for mitigating anxiety and depression. With the COVID-19 outbreak, such therapeutic interventions were delivered online. This longitudinal mixed-method study was aimed at evaluating the effectiveness of an online cognitive treatment, carried out during COVID times and based on Parkinson's-Adapted Cognitive Stimulation Therapy, on cognitive domains and mood of 18 older people with Parkinson's disease. After screening, the cognitive status and mood were assessed three times by Addenbrooke's Cognitive Examination-Revised scale and the Geriatric Depression Scale-Short Form. At the follow-up, patients were also interviewed for understanding their experience with the technology. Such treatment was effective on the participants' cognitive functions, but not on their mood. Despite some initial problems with the technology, the online intervention was experienced as a way of not being 'left behind', staying in contact with others, and being safe during the lockdown. This suggests that online cognitive treatment can be adopted to integrate face-to-face interventions by increasing their efficacy, accessibility, and long-term outcomes. Suggestions for future research are given.

Best practice approaches to outpatient management of people living with Parkinson's disease during the COVID-19 pandemic.

The prevalence of Parkinson's disease (PD) is rising, rendering it one of the most common neurodegenerative diseases. Treatment and monitoring of patients require regular specialized in- and outpatient care. Patients with PD are more likely to have a complicated disease course if they become infected with severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). Regular in-hospital appointments place these patients at risk of exposure to SARS-CoV-2 due to travel and contact with other patients and staff. However, guidelines for the management of outpatients with PD during times of increased risk of infection are currently lacking. These are urgently needed to conduct risk-benefit evaluations to recommend the best medical treatment. This article discusses best practice approaches based on the current literature, as suggested by the multidisciplinary Network of University Medicine (NUM) in Germany. These include measures such as mask-wearing, hand hygiene, social distancing measures, and appropriate testing strategies in outpatient settings, which can minimize the risk of exposure. Furthermore, the urgency of appointments should be considered. Visits of low urgency may be conducted by general practitioners or via telemedicine consultations, whereas in-person presentation is required in case of moderate and high urgency visits. Classification of urgency should be carried out by skilled medical staff, and telemedicine (telephone or video consultations) may be a useful tool in this situation. The currently approved vaccines against SARS-CoV-2 are safe and effective for patients with PD and play a key role in minimizing infection risk for patients with PD.

Research on depression in Parkinson disease: A bibliometric and visual analysis of studies published during 2012-2021.

BACKGROUND: The diagnosis and treatment rate of Parkinson disease (PD) with depression has a low diagnostic rate, and there is no consensus on the choice of treatment mode. This study evaluates the global research trends of scientific outputs related to depression in PD from multiple perspectives, using a bibliometric analysis and visualization tool to scientifically analyze the knowledge from the literature. METHODS: Literature related to depression in PD published from 2012 to 2021 was included and selected from the Web of Science Core Collection database in October 2021. CiteSpace software was used to visualize and analyze co-occurrence analyses for countries, institutions, authors, and keywords. RESULTS: A total of 4533 articles from the Web of Science database were included. The United States made the largest contribution with the majority of publications (1215; 29.40%). Toronto University was the most productive institution. PD, depression, quality of life, dementia, nonmotor symptom, prevalence, anxiety, Alzheimer disease, symptom, and disorder would be significantly correlated with depression in PD. The current hot spots in this field focus on the following: risk factors for depression in PD, assessment scale of depression in PD, and rehabilitation of depression in PD. CONCLUSIONS: This analysis not only reveals the current research trends and hotspots but also provides some instructive suggestions on the development of depression in PD.

Movement disorders in COVID-19 times: impact on care in movement disorders and Parkinson disease.

PURPOSE OF REVIEW: The purpose of this review is to outline the impact of the COVID-19 pandemic on movement disorder holistic care, particularly in the care of people with Parkinson disease (PWP). RECENT FINDINGS: As the pandemic unfolds, a flurry of literature was published regarding the impact of COVID-19 on people with Parkinson disease including the direct impact of infection, availability of ambulatory care, loss of community-based team care, and acceptability of telemedicine. SUMMARY: COVID-19 has impacted the care of PWP in numerous ways. Recognizing infection in PWP poses challenges. Specific long-term complications, including emerging reports of long COVID syndrome is a growing concern. Caregivers and PWP have also been impacted by COVID-19 social isolation restrictions, with radical changes to the structure of social networks and support systems globally. In a matter of weeks, the global community saw an incredible uptake in telemedicine, which brought benefits and pitfalls. As PWP adapted to virtual platforms and the changing architecture of care delivery, the pandemic amplified many preexisting inequities amongst populations and countries, exposing a new 'digital divide'.

[Telecare in Parkinson's disease: A nationwide survey among Hungarian neurologists]. / Távellátás Parkinson-kórban: országos felmérés a magyar neurológusok körében.

Background and purpose: COVID-19 has made providing in-person care difficult. In most countries, including Hungary, telemedicine has partly served as a resolution for this issue. Our purpose was to explore the effects of COVID-19 on neurological care, the knowledge of neurology specialists on telemedicine, and the present state of telecare in Hungary, with a special focus on Parkinson's disease (PD). Methods: Between July and October 2021, a nationwide online survey was conducted among actively practicing Hungarian neurology specialists who were managing patients with PD. Results: A total of 104 neurologists were surveyed. All levels of care were evaluated in both publicly funded and private healthcare. Both time weekly spent on outpatient specialty consultation and the number of patients with PD seen weekly significantly decreased in public healthcare, while remained almost unchanged in private care (p<0.001); higher portion of patients were able to receive in-person care in private care (78.8% vs. 90.8%, p<0.001). In telecare, prescribing medicines has already been performed by the most (n=103, 99%). Electronic messages were the most widely known telemedicine tools (n=98, 94.2%), while phone call has already been used by most neurologists (n=95, 91.3%). Video-based consultation has been more widely used in private than public care (30.1% vs. 15.5%, p=0.001). Teleprocedures were considered most suitable for monitoring progression and symptoms of Parkinson's disease and evaluating the need for adjustments to antiparkinsonian pharmacotherapy. Conclusion: COVID-19 has had a major impact on the care of patients with PD in Hungary. Telemedicine has mitigated these detrimental effects; however, further developments could make it an even more reliable component of care.

The BioVisualSpeech Serious Game with Voice Exercises for People with Parkinson's Disease with Hypokinetic Dysarthria.

People with Parkinson's disease (PD) can have dysarthria, a voice disorder that affects speech intelligibility. To fight this disorder people may resort to speech and language therapy. Unfortunately, weekly speech therapy sessions may not be enough, because to achieve and maintain good voice quality, intensive training is required. Additionally, the COVID-19 pandemic brought attention to the need for alternative speech therapy treatments that complement face-to-face appointments. Here, we propose a serious therapy game to improve voice loudness that can be used for intensive therapy or when face-to-face appointments are not possible. The game integrates three voice exercises used in speech therapy sessions for people with PD and aims to provide motivation for patients to perform the exercises on a daily basis. This application evaluates the vocal intensity, vocal frequency and maximum phonation time, offering real-time visual feedback. It also allows pathologists to customize the exercises difficulty to the needs of each patient.

COVID-19 and Parkinson's Disease: Possible Links in Pathology and Therapeutics.

The outbreak of SARs-CoV-2 with emerging new variants is leading to global health crisis and has brought a major concern for patients with comorbidities. Parkinson's disease (PD) is a motor neurodegenerative disease involving various metabolic and psychological ailments along with the common occurrence of hyposmia as observed in COVID-19 patients. In addition, the observed surplus inflammatory responses in both diseases are also alarming. Alongside, angiotensin-converting enzyme 2 (ACE2) receptor, essentially required by SARS-CoV-2 to enter the cell and dopamine decarboxylase (DDC), required for dopamine synthesis is known to co-regulate in the non-neuronal cells. Taken together, these conditions suggested the probable reciprocal pathological relation between COVID-19 and PD and also suggested that during comorbidities, the disease diagnosis and therapeutics are critical and may engender severe health complications. In this review, we discuss various events and mechanisms which may have implications for the exacerbation of PD conditions and must be taken into account during the treatment of patients.

Parkinson's disease and Covid-19: The effect and use of telemedicine.

As a result of the Coronavirus Disease 2019 (Covid-19) pandemic the use of telemedicine and remote assessments for patients has increased exponentially, enabling healthcare professionals to reduce the need for in-person clinical visits and, consequently, reduce the exposure to the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). This development has been aided by increased guidance on digital health technologies and cybersecurity measures, as well as reimbursement options within healthcare systems. Having been able to continue to connect with people with Parkinson's Disease (PwP, PD) has been crucial, since many saw their symptoms worsen over the pandemic. Inspite of the success of telemedicine, sometimes even enabling delivery of treatment and research, further validation and a unified framework are necessary to measure the true benefit to both clinical outcomes and health economics. Moreover, the use of telemedicine seems to have been biased towards people from a white background, those with higher education, and reliable internet connections. As such, efforts should be pursued by being inclusive of all PwP, regardless of geographical area and ethnic background. In this chapter, we describe the effect he Covid-19 pandemic has had on the use of telemedicine for care and research in people with PD, the limiting factors for further rollout, and how telemedicine might develop further.

Depression in Patients with Parkinson's Disease: Current Understanding of its Neurobiology and Implications for Treatment.

Depression is one of the most frequent and burdensome non-motor symptoms in Parkinson's disease (PD), across all stages. Even when its severity is mild, PD depression has a great impact on quality of life for these patients and their caregivers. Accordingly, accurate diagnosis, supported by validated scales, identification of risk factors, and recognition of motor and non-motor symptoms comorbid to depression are critical to understanding the neurobiology of depression, which in turn determines the effectiveness of dopaminergic drugs, antidepressants and non-pharmacological interventions. Recent advances using in vivo functional and structural imaging demonstrate that PD depression is underpinned by dysfunction of limbic networks and monoaminergic systems, depending on the stage of PD and its associated symptoms, including apathy, anxiety, rapid eye movement sleep behavior disorder (RBD), cognitive impairment and dementia. In particular, the evolution of serotonergic, noradrenergic, and dopaminergic dysfunction and abnormalities of limbic circuits across time, involving the anterior cingulate and orbitofrontal cortices, amygdala, thalamus and ventral striatum, help to delineate the variable expression of depression in patients with prodromal, early and advanced PD. Evidence is accumulating to support the use of dual serotonin and noradrenaline reuptake inhibitors (desipramine, nortriptyline, venlafaxine) in patients with PD and moderate to severe depression, while selective serotonin reuptake inhibitors, repetitive transcranial magnetic stimulation and cognitive behavioral therapy may also be considered. In all patients, recent findings advocate that optimization of dopamine replacement therapy and evaluation of deep brain stimulation of the subthalamic nucleus to improve motor symptoms represents an important first step, in addition to physical activity. Overall, this review indicates that increasing understanding of neurobiological changes help to implement a roadmap of tailored interventions for patients with PD and depression, depending on the stage and comorbid symptoms underlying PD subtypes and their prognosis.

SARS-CoV-2 vaccination, Parkinson's disease, and other movement disorders: case series and short literature review.

BACKGROUND: Several neurological complications have been reported following SARS-Cov-2 vaccination, without a clear causal relationship ever being verified, including some cases of worsening of Parkinson's disease (PD) symptoms and new onset of movement disorders in non-parkinsonian patients. METHODS: We describe two new cases of PD patients treated with device-aided therapy who developed worsening of parkinsonian symptoms after receiving the third vaccine dose (booster). We also conducted a short review of the cases reported in literature of PD symptoms worsening and new onset of movement disorders in non-parkinsonian patients after SARS-Cov-2 vaccination. RESULTS: The first patient, a 46-year-old man implanted with bilateral Subthalamic Deep Brain Stimulation, experienced temporary motor and non-motor symptoms worsening after mRNA-1273 booster, improved after stimulation settings modification. The second patient, a 55-year-old man implanted with percutaneous endoscopic transgastric jejunostomy (PEG-J) for levodopa-carbidopa intestinal gel (LCIG) infusion experienced severe temporary worsening of dyskinesia and managed through temporary LCIG dose reduction. Other seven cases of vaccine-related movement disorder are currently reported in literature, four describing PD symptoms worsening and three the onset of new movement disorders in otherwise healthy people. CONCLUSION: Both our patients and the cases described so far completely recovered after few days with parkinsonian therapy modification, symptomatic treatment, or even spontaneously, underlining the transient and benign nature of side effects from vaccine. Patients should be reassured about these complications, manageable through a prompt evaluation by the reference neurologist.
