Narcolepsy - Doberman Pinscheris a hereditary disease which can be tested with a DNA test. Narcolepsy is a disabling sleep disorder affecting different dog breeds. It is characterized by daytime sleepiness, cataplexy, and striking transitions from wakefulness into rapid eye movement (REM) sleep. Dogs with narcolepsy exhibit cataplexy, sudden episodes of muscle weakness akin to REM sleep–associated atonia that are triggered primarily by positive emotions. Animals in narcoleptic state are almost without muscular tonus. The first signs of disease may be apparent as early as 4 weeks to 6 months of age. The frequency of episodes is specific for each animal, however the frequency of episodes in general is declining with age.
