    #181 A primer on ICP management

    #181 A primer on ICP management

    The field of neurocritical care and traumatic brain injury management is rapidly evolving. We are shifting from older (but not entirely outdated) monitoring techniques to novel diagnostic and therapeutic advances in critical care medicine. Managing intracranial pressure crises involves the careful tiptoeing of a line between maintaining brain circulation and yet reducing intracranial fluid volume. And many of our interventions rely on one simple mathematical construct:
    CPP = MAP - ICP
    [Cerebral perfusion pressure = Mean arterial pressure – Intracranial pressure]
    The importance of this formula cannot be understated. So we are spending 35 minutes today reviewing it, and discussing pearls and pitfalls of ICP monitoring and management. But believe me, it’s worth it.
    Produced by James E. Siegler and Jon Rosenberg. Music courtesy of Unheard Music Concepts, Rafael Archangel, Milton Arias, and Quincas Moreira. The opening theme was composed by Jimothy Dalton.

    #180 The art of the pivot

    #180 The art of the pivot

    What do hip weakness, headache, and neglect have in common? At minimum, they can all be approached with simple neurodiagnostic heuristics. But there's more to neurology and medicine than having an approach to "leg weakness" or an approach to "headache". You have to adapt to new information as it presents itself. You have to know when, and how, to pivot.

    #178 First seizure of life

    #178 First seizure of life

    As many as 1% of the world has epilepsy, but far more than will have a seizure in their lifetime. Not everyone needs a seizure medication, some people are even harmed by them. So who warrants treatment, and what do you start with.
    Consider today’s program an intro to AED decision making. For educational purposes only, of course. Not to guide any healthcare provider’s decision making.

    #177 Agnosia

    #177 Agnosia

    To quote Donald Rumsfeld, “there are things we know we know…. we know there are some things we do not know... But there are also unknown unknowns—the ones we don't know we don't know…it is the latter category that tends to be the difficult ones.”
    In neurology, the agnosias are not that dissimilar from Rumsfeld’s 'unknown unknowns.' In this week’s program, we discuss the nosology and nomenclature for the agnosias, the localization, and the importance of recognizing one.

Autumn Leif ,

Fusion of clinical, academic, and artistic excellence and auditory delight

Recommended for both neurologists and neuroenthusiasts as this podcast is just as informative as entertaining! Very well done!

Breezy Snuk ,

Must listen for any neurologist

Terrific in every way!!!

Shelz57 ,

I love this podcast!!

I love listening this this podcast. I work specifically with headaches but getting input about other neurological disorders, assessments, differentials, etc really helps me when ruling out secondary causes for headaches in the clinic. Plus, Jim is very enjoyable to listen to!
