Narcolepsy is a neurological disorder caused by the brain’s inability to regulate sleep-wake cycles. Working with narcoleptic Doberman Pinschers, researchers discovered that canine narcolepsy is inherited directly from the parents and is an autosomal recessive trait, meaning both parents must pass down the mutated gene for the offspring to develop the disorder. Although there is not yet a cure for human narcolepsy the Doberman Pinscher may provide an important clue to understanding why they both fell asleep…on and off the job.
