In the TV show, HOUSE, it's either lupus or its sarcoidosis. Only, it's never sarcoidosis. That's because sarcoidosis is such a heterogeneous condition and can affect practically any age group. In some patients, this idiopathic inflammatory disorder can also involve the nervous system. Also causing a variety of signs and symptoms ranging from mild headache to a proximal myopathy or even a CNS vasculitis. This week on the BrainWaves podcast, Dr. Jesse Thon reflects on the literature and shares his experience managing patients with this troubling condition. Produced by Jesse Thon and James E. Siegler.
