For Sushil Lakhani, MD, a day’s work may include anything from completing a sleep study, to treating outpatients with insomnia or narcolepsy, to helping veterans properly use equipment to help with sleep apnea, reports Duke University School of Medicine.

My first interest in neurology peaked in medical school during one of my rotations. My mentor and I went to the ER to consult with a patient who had a complaint of weakness. After watching him complete a thorough 45-minute neurology exam, he was able to pinpoint a diagnosis prior to even ordering any tests. The idea of practicing medicine using cool tools (ie reflex hammer) and a good old exam to provide a diagnosis really sparked my interest in neurology. No other specialty goes through a in depth exam as neurologist, and we get to carry around tools!
