Welcome to the exciting weekly edition of NeurologyLive® Brain Games! This interactive quiz series goes live every Sunday morning, featuring challenging questions crafted by expert physicians and clinicians in the realm of neurology. Whether you're a seasoned professional or a newcomer to the field, each quiz presents a compelling opportunity to test your knowledge on a wide array of clinical and historical topics within neurological care.

This week's quiz focuses on the elusive concept of Progression Independent of Relapse Activity (PIRA) in multiple sclerosis, a critical area of study for professionals managing the disease. Multiple sclerosis (MS) is complex, and understanding PIRA can significantly impact patient outcomes. Here’s what you can expect in this week’s quiz:

1. Which mechanism primarily drives progression independent of relapse activity (PIRA) in multiple sclerosis?

Options: A) Peripheral inflammation B) Cortical demyelination and neurodegeneration C) Relapsing inflammation of the CNS D) Axonal remyelination

2. What clinical feature is most indicative of PIRA in MS?

Options: A) Sudden, acute worsening of symptoms B) Gradual accumulation of disability without new relapses C) Increase in MRI gadolinium-enhancing lesions D) Rapid symptom improvement after corticosteroid use

3. In managing PIRA, which class of medications has shown potential benefits in slowing neurodegeneration?

Options: A) Corticosteroids B) Disease-modifying therapies C) Antidepressants D) Anti-inflammatory NSAIDs

Engaging in these brain games not only allows you to challenge yourself but also keeps you updated on crucial advancements and clinical considerations in neurology, especially concerning complex conditions like multiple sclerosis.
