Saw Dr Pistone for over 20 years. He figured put my sleep disorder diagnosis was from a head injury and chronic nerve pain while many only look to pulmonology issues and are unable to diagnosis the tougher sleep issues such as alpha delta sleep animosity or narcolepsy or secondary narcolepsy. Dr Pistone is one of the few neurologists that follows my neurologists research and understands how neurological disease effects sleep and has little to do w pulmonary function or the need for c pap.
