Disorder - NarcolepsyOrgan Systems Involved
Narcolepsy is a nervous system condition in which dogs are excessively sleepy during the daytime and have disrupted sleep patterns.
Narcolepsy affects the sleep patterns of dogs, and is characterised by excessive daytime sleepiness and napping (a key symptom, present in all cases). Affected animals usually begin to exhibit signs at around 4 -12 weeks of age. Dogs with narcolepsy often have disrupted sleep patterns and tend to have episodes where they will suddenly just fall asleep. In narcoleptic dogs excitement and emotion can trigger sleeping episodes, with eating being the main cause. Dogs will start eating, only to suddenly fall to the ground asleep. They can be woken if spoken to or shaken, but once they continue eating they are likely to simply fall asleep again. Play or presentation of food can also trigger attacks of generalised temporary muscle paralysis without sleep, in which the animal may wobble on its feet and look slightly dazed for several minutes. During such attacks the respiratory and eye muscles remain unaffected, though affected dogs may have impaired vision. Sleep paralysis, where upon waking or on dozing the animal is temporarily paralysed, and hypnologic hallucinations, where patients experience dream-like visions when dozing, though not in the dream stage of sleep, are also common symptoms in humans. Due to their subjective nature these symptoms cannot be used in diagnosing canine narcolepsy.
