Predictors of Cogntive Impairment in an Early Stage Parkinson’s Disease Cohort

Cognitive impairment is common in all stages of PD and accurate measurement scales are important.  Prior studies have indicated that the Montreal Cognitive Assessment (MoCA) is more sensitive than the Mini-Mental State Examination (MMSE) in identifying early PD cognitive impairment.  In this study, the researchers studied cognitive impairment in a sample of more than 400 early PD patients (duration< 3.5 years) compared to controls (N=141), and evaluated the ability of the MoCA and MMSE to identify change over time.  PD patients had significantly lower scores on the MoCA and MMSE compared to the controls (adjusting for age, sex, and years of education).  The fraction of patients classified with normal cognition, mild cognitive impairment (MCI) and dementia varied significantly, depending on the scoring criteria used.  Using the “screening” threshold for the MoCA (normal 26-30, MCI 21-25, dementia <  20), 47.7% of the PD patients were classified as having normal cognition, 40.5% with MCI, and 11.7% with dementia, compared to 63.8% in the control group with normal cognition, 19.9% with MCI and 16.3% with dementia. With the MMSE at screening threshold, 37.4%, 32.1%, and 30.5% of patients were classified as having normal cognition, MCI, and dementia respectively.    Eighteen months later, the assessments were repeated in 155 of the patients with PD; MoCA scores decreased significantly while the MMSE scores did not.  Cognitive impairment was associated with lower education, increased age, male sex, and quantitative motor and nonmotor (smell, depression, and anxiety) measures. The authors conclude that the MoCA may be more sensitive in identifying early, as well as longitudinal, cognitive impairment in patients with PD.

Randomized Trial of Safinamide Add-On to Levodopa in Parkinson’s disease with Motor Fluctuations

Levodopa is an effective treatment for motor symptoms in Parkinson’s disease (PD), but chronic use is associated with complications including motor fluctuations and dyskinesias. A recent phase III randomized, double-blind, placebo-controlled trial studied the effects of safinamide (a novel drug that is of particular interest because it effects multiple pathways besides dopamine regulation) as add-on therapy on motor fluctuations and dyskinesias in PD. Subjects were randomized to safinamide 100 mg/day (N=224), safinamide 50 mg/day (N=223) or placebo (N=222) for 24 weeks. In the primary analysis, subjects on either dose of safinamide reported approximately ½ hour per day more “on” time without troublesome dyskinesias. In addition, there was a similar reduction in off time. The UPDRS-III motor exam was improved in subjects on 50 mg and 100 mg safinamide and the UPDRS-II (measuring patient-reported symptom severity) was improved only in patients taking 100 mg safinamide. This study suggests that safinamide may be beneficial as add-on therapy to dopaminergic treatment in patients with motor fluctuations and disabling dyskinesias.

Pimavanserin for patients with Parkinson's disease psychosis: a randomised, placebo-controlled phase 3 trial.

 

Parkinson's disease (PD) psychosis, which includes hallucinations and delusions, is common and often disabling but treatment options are limited. This study aimed to assess safety and treatment effects of pimavanserin, an investigational drug, on symptoms including illusions, visual hallucinations and paranoid delusions. Patients with PD psychosis were randomly assigned to receive either the study drug (N=95) or a placebo (N=90). Their symptoms were evaluated at the beginning of the study, and 2, 4 and 6 weeks later using several methods, including the PD-adapted scale for assessment of positive symptoms (SAPS-PD). Antipsychotic treatments were not permitted during the study, but controlled PD medications, or deep brain stimulation was allowed. Patients taking pimavanserin had a significant decrease in their symptoms compared with patients taking placebo as indicated by SAPS-PD scores, doctors’ clinical global impression of change scores and decreased caregiver burden. Importantly, pimavanserin was well tolerated overall, and did not worsen motor function.  10 patients in the pimavanserin group stopped the drug because of a side effect compared with 2 in the placebo group. The QT interval was prolonged in some patients, making baseline electrocardiogram assessments necessary when using pimavanserin. The authors concluded that pimavanserin may benefit patients with PD psychosis who otherwise have few treatment options. Further study is needed because patients in this study were only followed for a relatively short time and the primary outcome scale (SAPS-PD) differs from prior studies of PD psychosis. Additionally, the pharmaceutical company that makes pimavanserin sponsored the study and employees helped analyze the results and write the article. It is possible that this degree of involvement in the study may have affected its reported outcome.

Committee Activities

 Clinical Care Committee

·       Rotation of Committee Chair: Leadership for the clinical care committee rotates amongst the PADRECCs.  The San Francisco PADRECC leads the committee for March/April.  Committee meets via conference call the first Tuesday of the month at 12pm (EST) 

 

·       Standardize and Optimize Clinical Care: Continues to discuss a variety of clinical issues to enhance patient care, the committee continues to provide clinical support to the Consortium network, and work on measures to standardize clinical care across the PADRECC network.  Recent agenda items have included ongoing discussion on:    

       

  • Use of Clinical Video Telehealth for movement disorders and  home monitoring devices

Review of applications in clinical arena for subset of patients, and ways to expand access to CBOCs  and remote areas where subspecialty expertise is not available.  Research ideas pertaining to the use of home monitoring devices in movement disorders patients.

 

  • Use of various Botulinum toxins

    Development of PMB guideline for clinical use of various toxins

 

  • The use of DAT scans in clinical practice 

Applications and pitfalls of use

 

  • PADRECC Transmitter: PADRECC clinicians provide reviews of recent movement disorder publications that are included in the PADRECC Transmitter

 

Education Committee

  • PADRECC/EES Movement Disorder Series:  The FY14  series is underway. The 3rd audio conference for this series was held on  March, 13, 2014 ,  " Diagnosis & Treatment of Ataxia and Cerebellar Disease.”   The audio conferences are archived on the National website www.parkinsons.va.gov under the Movement Disorder Series tab.  All evaluations for CMEs are being done electronically via TMS and preregistration is required.  Audio conferences are now held via Microsoft Lync, participants can use audio access through their computer or by calling a conference line (similar to VANTS).  Please  see the Dates to Remember section below for listing of upcoming audio conferences.
  • Patient Education Video Project:  The My Parkinson’s Story video series from FY 11 and FY 12 are now available for viewing on the National PADRECC & VA Consortium Website:  http://www.parkinsons.va.gov/patients.asp and on You Tube.   FY13 videos are in the editing phase and will be posted on You Tube when approved.   Request has been approved for another 4 videos for FY14.
  • Enduring Materials Project: In collaboration with EES, the committee is developing an on-line TMS self study program that will offer CME credit for a 3 year period.  The purpose of this training is to provide VHA healthcare professionals with a broadened medical awareness of Mood Disorders in PD.
  • PADRECC Transmitter: The committee continues to assemble and distribute this e-newsletter every other month.
