Pathophysiology, Patient Burden, and Recognition of OFF Episodes of Parkinson Disease

Overview

Do you talk with your patients with Parkinson disease about the burden of OFF episodes? Using assessment tools can spur communication. In this CME activity, follow along as 2 experts review the occurrence and identification of OFF time.

ABSTRACT

The pathophysiology of PD has been elusive, but the motor symptoms of the disease are believed to result from a dopamine deficiency in the substantia nigra. As a patient’s disease progresses, OFF episodes emerge due to a shorter duration of response to levodopa treatment. OFF episodes include both motor and nonmotor symptoms, are common, and can occur at any time. OFF episodes can be predictable or unpredictable, significantly impact patient quality of life and functionality, and place a burden on families. By facilitating communication with patients and care partners using assessment tools, clinicians can detect symptoms of OFF episodes earlier.

CME Objective

After completing this educational activity, you should be able to:

  • Consider how the pathophysiology of Parkinson disease (PD) contributes to patient burden and OFF periods
  • Identify signs of OFF periods by incorporating questionnaire use and care partner information into the clinical evaluation

Release, Review, and Expiration Dates

This brief report activity was published in October 2020 and is eligible for AMA PRA Category 1 Credit™ through October 31, 2022. The latest review of this material was September 2020.

Statement of Need and Purpose

Physicians and patients are not communicating clearly about OFF episodes, and detection through clinical evaluation alone is less accurate than if an assessment tool is used. Neurologists, therefore, need education on the use of assessment tools, facilitating good communication with patients and care partners, and risk factors for OFF periods. Because therapeutic strategies for OFF episodes have expanded, and guidelines were recently updated, clinicians also need education from experts about new treatment strategies for OFF episodes and current guidelines. This activity was designed to meet the needs of participants in CME activities provided by the CME Institute of Physicians Postgraduate Press, Inc., who have requested information on Parkinson disease.

Disclosure of Off-Label Usage

Dr Pahwa has determined that, to the best of his knowledge, no investigational information about pharmaceutical agents or device therapies that is outside US Food and Drug Administration–approved labeling has been presented in this activity.

Review Process

The faculty members agreed to provide a balanced and evidence-based presentation and discussed the topics and CME objectives during the planning sessions. The faculty’s submitted content was validated by CME Institute staff, and the activity was evaluated for accuracy, use of evidence, and fair balance by the Chair and a peer reviewer who is without conflict of interest.
