Abdominal migraine is often regarded as a childhood disorder and less commonly described in adults. However, gastrointestinal symptoms are known to occur to adult migraine patients, and recognition of adult abdominal migraine may facilitate treatment of the recurrent abdominal symptoms and avoidance of unproductive and sometimes invasive therapies. Here, I describe a patient with chronic migraine headaches and recurrent abdominal pain both of which showed sustained improvement after treatment with onabotulinumtoxinA injections.

Parkinson's disease (PD) is associated with non-motor symptoms (NMS) that can cause progressive disability and impact quality of life of people with PD (PwP) and increase burden on care partners. This survey was designed to evaluate the prevalence, impact, and educational preferences regarding NMS on PwP and their care partners. A 17-question survey was sent to the total membership of PMDAlliance, a nonprofit organization reaching 3,685 households of PwP. Care partners and other interested individuals could also respond. The survey was conducted using Survey Monkey, an online survey platform, and included distinct questions for respondents with and without NMS. A total of 700 individuals responded to the survey. Of the respondents, 378 (54%) were care partners and 287 (41%) were PwP. About 90% of the respondents reported having experience with NMS in PwP, including sleep problems (84%), cognitive symptoms (76%), anxiety (65%), depression (56%), hallucinations (40%), and delusions (23%). NMS in PwP were reported by more care partners (97%) than PwP (80%). NMS had at least some impact on quality of life for 84% of the respondents; 48% indicated that NMS represented a greater challenge than motor symptoms. Care partners were more likely than PwP to report that NMS were more challenging than motor symptoms (58% vs 32%). Respondents with and without NMS indicated a desire for NMS education. This survey underscores the significant impact of NMS on the quality of life of PwP and highlights the need for improved recognition and education about its effects.

As the COVID-19 pandemic resulted in social restrictions around the globe, this cross-sectional survey aimed to assess the impact of social isolation on self- or proxy-reported symptoms of Parkinson's disease (PD) during the pandemic. The survey was distributed among 7109 subscribers of the Parkinson and Movement Disorders Alliance (PMD Alliance) News and Information list and was open only to people with PD (PwP) and care partners (CP, defined as main caregivers of PwP and serving as proxy respondents). No attempt was made to identify PwP and CP pairs. The survey was distributed online using Survey Monkey between 01/06/2021 and 02/27/2021. Respondents were grouped by level of social support from outside of their household during the pandemic (decreased or maintained [ie, the same as pre-pandemic or increased]). Of 7109 invited participants, 718 responded to the survey (response rate 10.1%). PwP (self-reports) accounted for 70.6% of respondents and CP (proxy reports) for 29.4%. Decreased social support from outside of the household during the COVID-19 pandemic (58.5% of all responses) was significantly associated with increases in sadness/depression and anxiety, compared with maintained levels of social support (p < 0.0001 for both comparisons). It was also associated with increased burden of several non-motor (decline in memory, problem solving, or communication, p = 0.0009; new or worsening confusion, p < 0.0001; new or worsening delusions, p = 0.018) and motor PD symptoms. Decline in social support from outside of the household during the COVID-19 pandemic showed a statistically significant and negative association with the burden of mood and non-motor symptoms of PD. These results call for increased vigilance towards non-motor symptoms in PwP experiencing social isolation and highlight the need for stronger provider focus on encouraging PwP and their CPs to build and maintain social connections and engagements.

Clinical care for patients with Parkinson's disease (PD) is complex, and disconnect may exist between patient and physician perceptions of treatment, disease awareness, and impact on quality of life (QoL). Relatively few studies have analyzed patient and physician perspectives of disease management concurrently, and even fewer have compared responses between corresponding patients and their physicians. This study aimed to characterize these aspects and identify opportunities to improve alignment. This cross-sectional study used an online survey and chart review. Participating physicians completed a profiling survey, followed by patient record forms (PRFs) for their next five patients with PD. Patients completed paper questionnaires. PRFs were matched with patient questionnaires, and patient and physician responses compared. Of 107 participating physicians, 70 completed 350 PRFs. Patients completed 71 questionnaires; 66 were matched to PRFs. From a physician perspective, there was alignment between the motor symptoms that were most bothersome for patients and those that were most discussed (physicians felt tremor was most bothersome for most patients [71%]; 77% of physicians included tremor among top three most discussed), but disconnect between the most bothersome and most discussed nonmotor symptoms (physicians felt fatigue was most bothersome for most patients [35%]; cognitive impairment was the most discussed nonmotor symptom, with 52% of physicians including it in top three most discussed). Patients and physicians reported moderate satisfaction with current PD medication. Patients considered form of delivery more important than did physicians. Physicians showed a strong level of awareness of PD's impact on patient QoL, although validated QoL instruments were not widely used. Physicians were more confident than patients about patients' awareness of support resources for patients with PD. Nonmotor symptoms, form of medication delivery, and awareness of support services are areas where PD physician and patient alignment could be increased to improve outcomes.

Parkinson’s disease psychosis (PDP) occurs commonly and can comprise the most troubling symptoms among the many that occur with this illness. Prior treatment options for PDP have been limited and unsatisfactory due to uneven efficacy data, burdensome monitoring, and lack of a specific FDA indication coupled with warnings of increased mortality. Pimavanserin, approved for the treatment of PDP by the FDA in 2016, overcomes some of these obstacles, with data proven efficacy and without the frequent monitoring required for clozapine. This presents an opportunity to transition patients with PDP to pimavanserin from older therapies. Black and colleagues provide their thoughtful recommendations on how to achieve this transition to pimavanserin while maintaining symptom control and minimizing disruptions that might occur with a medication change.

A growing number of environmental and pharmacologic manipulations have been shown to influence adult neurogenesis. Borna disease virus (BDV) in rats causes cortical and subcortical infection with extrapyramidal motor symptoms, and hippocampal infection suppresses neurogenesis. Given the known effects of cannabinoids in promoting neural progenitor cell survival, the authors examined in vivo effects of chronic BDV infection in rats on BrdU-positive progenitor cells in striatum, together with neuroprotective actions of cannabinoids. Birth and survival of BrdU-positive progenitor cells in striatum of BDV-infected rats treated with a general cannabinoid agonist (WIN 55,212 1 mg/kg i.p. b.i.d. × 7 days) were examined, as well as anti-inflammatory, antiviral, and nutritional effects of cannabinoids. Cannabinoid treatment protected BrdU-positive progenitor cells in striatum that were susceptible to virus-induced injury (p < .01) through suppression of microglia activation (p < .001). As a consequence of their anti-inflammatory actions and support of neural progenitor cell survival, cannabinoids may be adjunctive treatment for encephalitides with microglial inflammation and neurodegeneration.

Few centers have routinely implemented robotic stereotactic systems for deep brain stimulator (DBS) placement. The present study compares clinical outcomes associated with robotic-assisted subthalamic nucleus (STN)-targeted DBS surgery in patients with Parkinson’s disease (PD) to those of the traditional frame-based method. A retrospective chart review was performed (February 2013–June 2017). Thirty-three patients were implanted using the Cosman–Roberts–Wells (CRW) frame and 27 patients were implanted using the ROSA robot. Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) or UPDRS part III motor scores and levodopa equivalent daily doses (LEDD) were examined preoperatively and at 6, 12, and 24 months of follow-up. Operative times and complication rates were recorded. For the frame-based group, the reduction in the mean MDS-UPDRS part III motor score compared to baseline was 27% both at 6 and 12 months, and 36.7% at 24 months. For the robotic-assisted group, the reduction in the mean motor score from baseline was 17.6% at 6 months, 19% at 12 months and 21.4% at 24 months. The mean LEDD for the frame-based group decreased by 48.7% at 6 months, 56.7% at 12 months, and 29.7% at 24 months. For the robotic-assisted group, the mean LEDD decreased by 42% at 6 months, 45% at 12 months and 50% at 24 months. There were no significant differences in the mean motor scores and the LEDD reduction between the two groups. Operative times tended to be longer for robotic-assisted DBS surgery. Clinical outcomes associated with robotic-assisted surgery are comparable to those with frame-based surgery.

Background Adults with moderate-to-severe primary restless legs syndrome (RLS) often experience painful dysesthesias, which may lead to impaired quality of life. Objectives The aim of this study was to assess the effects of gabapentin enacarbil (GEn) on pain associated with moderate-to-severe primary RLS in adults. Methods Data were pooled from three double-blind, randomized, placebo-controlled, 12-week trials (NCT00298623, NCT00365352, NCT01332305) for adults receiving GEn or placebo once daily. Change in average daily RLS pain score and a combined International Restless Legs Scale (IRLS)–pain response were examined. Results The modified intention-to-treat population included 671 adults (placebo, n  = 244; GEn 600 mg, n  = 161; GEn 1200 mg, n  = 266). Both GEn doses significantly improved average daily RLS pain score at week 12 ( p  < 0.001 for GEn 600 mg vs. placebo and GEn 1200 mg vs. placebo). The combined IRLS–pain response subanalysis included 366 patients with a baseline IRLS total score ≥15 and pain score ≥4 (placebo, n = 133; GEn 600 mg, n = 86; GEn 1200 mg, n  = 147). Most patients were both IRLS and pain responders (placebo, 40 %; GEn 600 mg, 70 %; GEn 1200 mg, 67 %). Spearman rank correlations between IRLS total and pain score (change from baseline to week 12) were moderate or strong. The most frequent treatment-emergent adverse events were somnolence (placebo, 5 %; GEn 600 mg, 20 %; GEn 1200 mg, 23 %) and dizziness (placebo, 4 %; GEn 600 mg, 13 %; GEn 1200 mg, 22 %). Conclusions This post hoc pooled analysis suggests that GEn (600 and 1200 mg) once daily significantly improved pain associated with moderate-to-severe primary RLS in adults; however, the analysis was not powered to detect statistical differences between the two GEn doses. Numerically, more GEn-treated patients had a combined IRLS–pain response than placebo-treated patients.

Purpose Although diseases of the lower gastrointestinal tract are common in patients with Parkinson’s disease, there is a paucity of data regarding postoperative outcomes after colorectal surgery. Methods The Nationwide Inpatient Sample database (2007–2011) was utilized to analyze outcomes in patients with Parkinson’s disease (PD) undergoing colorectal surgery. Main outcomes were risk-adjusted inpatient morbidity, mortality, hospital charge, and length of hospital stay. Results A total of 6490 patients were identified. Utilization of laparoscopic surgery in Parkinson’s patients has progressively increased in frequency over the latest 5 years analyzed. The most common diagnoses were colorectal malignancy (39 %) and intestinal obstruction (20 %). Right hemicolectomy (37 %) and sigmoidectomy (30 %) were the most common operations. Laparoscopy was used in 18 % of Parkinson’s patients and most commonly in the elective setting. 54.3 % of Parkinson’s patients had emergency surgery compared to 38.6 % in non-Parkinson’s. Overall morbidity and mortality were significantly lower after laparoscopic surgery compared to open (20 vs. 25 % and 2.1 vs. 6.6 %, respectively). Length of stay was significantly shorter (OR −1.86; p  < 0.01) for laparoscopic operations, but there were no significant differences in risk-adjusted outcomes between laparoscopic and open groups. Conclusion PD patients have high rates of morbidity and mortality after colorectal surgery; this may be because more than half of all patients in this population undergo emergent surgery. The laparoscopic approach appears to have short-term benefits in this patient population.

As the population ages, the incidence of Parkinson's disease is likely to increase. Unfortunately, the diagnosis can be complex, and current treatment options offer symptomatic relief in many patients but no cure for the underlying neurodegeneration. In this article, Dr Hermanowicz offers a concise overview of possible etiologic factors, clinical features, treatment principles and practice, and new therapeutic approaches that may improve management of Parkinson's disease in the future.
