It's the age of thrombectomy. The DAWN of a new era. But should we give up on intravenous thrombolysis for acute ischemic stroke? In this installment of the Quanta series (typically shorter episodes, this one happens to be 19 minutes), we review the latest data on fibrinolytic agents and anticipate the upcoming paradigm shift in the management of patients with cerebral infarction.

Produced by James E Siegler. Music by Hyson and Jon Watts. BrainWaves' podcasts and online content are intended for medical education only and should not be used for clinical decision-making.

Apomorphine has a more than 20-year history as a therapeutic adjunct in the management of idiopathic Parkinson disease. And yet, no randomized, placebo-controlled clinical trial to show for it. As of July 2018, now there is. In this week's episode of BrainWaves, Dr. Siegler discusses the relevance, strengths, and weaknesses of the TOLEDO trial.

As my wife and I are raising our 9-month-old daughter, and she is eating more solid food, I can't help but think about how important it is for her to keep an open mind to new food groups. But being open-minded is not just a lesson for toddlers. I emphasize it every day on rounds when seeing patients for a "stroke consult" or a consult for "ICU delirium." If you reduce yourself to the same anchoring biases that you've grown accustomed to, you'll never entertain the possibility of other important and treatable conditions. Or tasty foods. This week on the BrainWaves Podcast, Dr. Brian Jankowitz (Cooper University Hospital Vascular Neurosurgeon) joins Jim in a discussion about a rare but treatable cause of myelopathy. A condition you won't want to miss.

Produced by Brian Jankowitz and James E Siegler. Music courtesy of Kevin McLeod, Lee Rosevere, and Loyalty Freak Music. The opening theme was composed by Jimothy Dalton. Sound effects by Mike Koenig and Daniel Simion. Unless otherwise mentioned in the podcast, no competing financial interests exist in the content of this episode.

Can you hear that too? You can't? Well, that doesn't mean I'm having auditory hallucinations. It could just be tinnitus, which describes the irritating sound of ringing, buzzing, clicking, or hissing that affects 10% to 20% of the world's population. But is this a ringing in the ears or a ringing in the brain?
