RESUMEN
BACKGROUND: Delivering specialty care remotely directly into people's homes can enhance access for and improve the healthcare of individuals with chronic conditions. However, evidence supporting this approach is limited. MATERIALS AND METHODS: Connect.Parkinson is a randomized comparative effectiveness study that compares usual care of individuals with Parkinson's disease in the community with usual care augmented by virtual house calls with a Parkinson's disease specialist from 1 of 18 centers nationally. Individuals in the intervention arm receive four virtual visits from a Parkinson's disease specialist over 1 year via secure, Web-based videoconferencing directly into their homes. All study activities, including recruitment, enrollment, and assessments, are conducted remotely. Here we report on interest, feasibility, and barriers to enrollment in this ongoing study. RESULTS: During recruitment, 11,734 individuals visited the study's Web site, and 927 unique individuals submitted electronic interest forms. Two hundred ten individuals from 18 states enrolled in the study from March 2014 to June 2015, and 195 were randomized. Most participants were white (96%) and college educated (73%). Of the randomized participants, 73% had seen a Parkinson's disease specialist within the previous year. CONCLUSIONS: Among individuals with Parkinson's disease, national interest in receiving remote specialty care directly into the home is high. Remote enrollment in this care model is feasible but is likely affected by differential access to the Internet.

OBJECTIVE: To determine whether providing remote neurologic care into the homes of people with Parkinson disease (PD) is feasible, beneficial, and valuable. METHODS: In a 1-year randomized controlled trial, we compared usual care to usual care supplemented by 4 virtual visits via video conferencing from a remote specialist into patients' homes. Primary outcome measures were feasibility, as measured by the proportion who completed at least one virtual visit and the proportion of virtual visits completed on time; and efficacy, as measured by the change in the Parkinson's Disease Questionnaire-39, a quality of life scale. Secondary outcomes included quality of care, caregiver burden, and time and travel savings. RESULTS: A total of 927 individuals indicated interest, 210 were enrolled, and 195 were randomized. Participants had recently seen a specialist (73%) and were largely college-educated (73%) and white (96%). Ninety-five (98% of the intervention group) completed at least one virtual visit, and 91% of 388 virtual visits were completed. Quality of life did not improve in those receiving virtual house calls (0.3 points worse on a 100-point scale; 95% confidence interval [CI] -2.0 to 2.7 points; p = 0.78) nor did quality of care or caregiver burden. Each virtual house call saved patients a median of 88 minutes (95% CI 70-120; p < 0.0001) and 38 miles per visit (95% CI 36-56; p < 0.0001). CONCLUSIONS: Providing remote neurologic care directly into the homes of people with PD was feasible and was neither more nor less efficacious than usual in-person care. Virtual house calls generated great interest and provided substantial convenience. CLINICALTRIALSGOV IDENTIFIER: NCT02038959. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for patients with PD, virtual house calls from a neurologist are feasible and do not significantly change quality of life compared to in-person visits. The study is rated Class III because it was not possible to mask patients to visit type.

Restless legs syndrome (RLS) is a common condition characterized by an unpleasant urge to move the legs that usually occurs at night and may interfere with sleep. The medications used most commonly to treat RLS include dopaminergic drugs (levodopa, dopamine agonists), benzodiazepines, and narcotic analgesics. We report the cases of 2 patients with RLS who illustrate the problems of tolerance (declining response over time) and augmentation (a worsening of symptoms due to ongoing treatment) that can complicate the pharmacotherapy of RLS. We discuss the optimal management of RLS and propose strategies to overcome tolerance and augmentation such as a rotational approach among agents from different classes.

Patients with Parkinson's disease (PD) can experience cognitive impairment. There are currently no medications indicated for the treatment of cognitive impairment in PD. Clinicians are faced with the dilemma as to whether or not to treat patients with PD with the acetylcholinesterase inhibitors that are currently approved for use in Alzheimer's disease (AD) and that have shown promise in clinical trials of Dementia with Lewy bodies (DLB). Although these medications may help cognition, there is a theoretical concern that by increasing acetylcholine relative to dopamine, they might worsen motor function. We report the case of a patient with PD and cognitive impairment who developed a marked worsening of motor function, mood, and anxiety in the setting of a pharmacologic challenge study using a 3-mg oral dose of the acetylcholinesterase inhibitor, rivastigmine. We believe that the mechanism of the motor and perhaps psychiatric worsening was increased central cholinergic tone. We conclude that further studies should be done to evaluate the efficacy and tolerability of these agents in this illness but that caution should be exercised when using acetylcholinesterase inhibitors in patients with PD.

Parkinson's disease (PD) is a neurodegenerative condition that is on the rise as the world's population ages. As our understanding of the disease increases, depression has emerged as a common syndrome in this population that significantly reduces quality of life, making its understanding, recognition and treatment an important area of focus for clinicians and researchers alike. It is hypothesized that depression is a consequence of the disease process itself, sometimes developing prior to the onset of motor symptoms. Many of the diagnostic tools and treatments for depression have not been fully evaluated in the PD population. However, several traditional diagnostic interviews and depression rating scales have been used in recent clinical trials. These study results suggest that some of the currently available antidepressant medications may be effective and well tolerated in this population. This paper reviews our understanding of depression in PD as well as the current recommendations for its diagnosis and treatment.

This article provides an update on depression and apathy in Parkinson's disease (PD), both of which are common but often misunderstood. The diagnosis of depression in PD can be challenging and we still do not have solid evidence on which to base our treatment decisions. Apathy is most commonly seen in the setting of dementia or depression but emerging evidence suggests that it may be a core feature of PD. There are conflicting reports about the effects of deep brain stimulation (DBS) on mood and apathy, but studies suggest that at least some patients may develop depression and apathy after the procedure. Although we are making strides toward a better understanding of depression and apathy in PD, it is clear that more research is needed about these non-motor features.

We report results of a survey assessing patients' knowledge about and attitudes towards depression in Parkinson's disease (PD). 345 patients from 8 tertiary care centers responded (43% response rate). Overall, patients were relatively knowledgeable about depression and its occurrence in PD. However, many patients believed that depression is a normal reaction to the illness. While many respondents would be reluctant to initiate a discussion of depression during a clinical evaluation, most would feel comfortable talking about depression with their physician if he or she asked them questions about their mood. Based on the results of this survey, we recommend the following approach for physicians: (1) inform PD patients that, although a frequent occurrence, depression need not be accepted as a "normal reaction" to PD; and (2) routinely inquire about depressive symptoms rather than waiting for the patient to spontaneously report them.
RESUMEN
Depression is common in patients with Parkinson's disease (PD) and has been identified as the main factor negatively impacting quality of life. It has been reported that depression in PD is under-recognized and under-treated. We report on 90 patients with PD who completed the Geriatric Depression Rating Scale (GDS). Thirteen subjects (14%) scored above 15, the proposed cut-off for diagnosing depression in this illness. Detailed medical record review for these subjects revealed that depression was recognized and treated in only about one-half of the cases. Comparison of mean subscale scores between subjects scoring above and below the cut-off for diagnosis of depression revealed that each of 6 proposed subscales effectively distinguished the two groups. Review of individual items demonstrated that many of the subjects endorsed low energy, regardless of whether they were depressed. This study supports the notion that efforts should be made to educate patients, caregivers and physicians about identifying depression in PD. The routine use of a depression rating scale may facilitate the recognition of depression in this illness.
RESUMEN
OBJECTIVES: Parkinson's disease (PD) is associated with motor fluctuations that have been shown to improve when stable plasma levodopa levels are achieved with continuous levodopa infusions. Many patients also develop mood fluctuations. In this pilot study, we gathered preliminary information about the relationship between changing mood states and plasma levodopa levels. METHODS: Six patients with idiopathic PD and histories of motor and mood fluctuations participated in a double-blind levodopa infusion study. Subjects received active oral carbidopa/levodopa and a placebo levodopa infusion on one day and placebo oral carbidopa/levodopa and an active levodopa infusion on the other day, in a randomly determined order. Evaluations included serial plasma levodopa levels and assessments of mood and motor states. RESULTS: Only 4 of the 6 subjects demonstrated mood fluctuations on at least one of the treatment days. All subjects achieved more stable plasma levodopa levels on the active infusion day. Two subjects experienced fewer mood fluctuations on the active infusion day and two experienced fewer on the oral day. Conclusions The results of this pilot study suggest that the relationship between mood state and plasma levodopa level may vary among PD patients.
RESUMEN
Psychosis in Parkinson's disease (PD) is a major source of distress to patients and caregivers. Although the advent of atypical antipsychotic agents has, to some extent, resolved a clinical dilemma by preserving motor function while treating psychosis, our understanding of psychosis in PD remains in a nascent state. In this article the authors address several issues relating to psychosis in PD including the following: 1) prevalence, 2) possible etiologies and risk factors and 3) treatment. They also identify limitations in our understanding of this complex phenomenon and conclude that, despite availability of reasonable treatments for psychosis in PD, the search for a better understanding of the phenomenon must continue.

Parkinson's disease (PD) and dementia with Lewy bodies (DLB) have clinical features in common and are both characterized neuropathologically by the presence of Lewy bodies (LBs). We conducted a clinicopathological correlation pilot study to better understand whether PD and DLB represent two distinct nosological entities or rather exist along the spectrum of a single LB disease. A neuropathologist blinded to clinical diagnoses evaluated brains with largely pure LB pathology to determine LB distribution and frequency. Research clinicians blinded to LB distribution and frequency determined consensus clinical diagnoses. Clinical features separated cases into two groups, one having features most compatible with PD and the other with DLB. The groups were distinguishable mainly by the time course of clinical symptoms. Although the presence of neocortical LBs was more common in the group of patients with clinical features of DLB, neocortical LBs were also present in 1 member of the PD group and even in the clinically normal control subject. Thus, there appear to be two clinical syndromes, distinguished mainly by the time course of symptoms. The mechanisms responsible for the different clinical presentations are not known, and the issue of whether PD and DLB represent two distinct diseases remains unsettled.
