I'll throw in my 2 cents as well, as someone who pursued a residency in PM&R followed by a Neurology-based Neuromuscular Medicine fellowship. There are definitely differences between the training in both specialties, but there is quite a bit of overlap in patient population. From my experience, on the neurologic disease side of things, Neurology tends to participate more in the acute aspect of neurologic conditions and the initial work-up, diagnosis, and medicinal management of these conditions, while PM&R tends to participate in the long-term management of the patient's rehabilitation needs, spasticity, pain, bladder/bowel management, DME, wheelchairs, and other quality of life aspects. Both sides have their pros and cons, just depending on what you are interested in. You received great advice above which I would keep in mind while thinking about this decision. As well, like was mentioned, PM&R can do fellowships in neurocritical care (a newer development), brain injury medicine, spinal cord injury medicine, neuromuscular medicine (99% of these fellowships are in Neurology departments), and even more specific non-accredited fellowships in advanced spasticity management or multiple sclerosis rehabilitation. There will be regional variation on how PM&R is viewed by other physicians and hospital systems. Patients love their PM&R physicians and you do get the opportunity to build lasting relationships with your patients as you help them throughout their lives.
