Paroxysmal narcolepsy syndrome

Paroxysmal lethargy syndrome, also known as Kleine-Leine syndrome (KLS), is a rare syndrome. In 1925, Kleine reported a group of patients, all of whom were young men. When they became ill, they were awake at all times except when eating and urination. The patient can also be awakened during sleep, and he can get up to urinate on his own, but when he wakes up, he has to eat immediately, and when he eats, he eats an astonishing amount. One person eats as little as 2 to 3 kilograms a day, and as many as 5 ~ 6 pounds of food. When asked why he ate so much, the patient would answer without hesitation: ldquo; Hungry. rdquo; If you do n’t give something to eat, you will make a lot of noise and even scold. In 1936, Levin discovered that these patients had special pathological hunger, so Levin called the disease a periodic lethargy-pathological hunger syndrome. Gritchley and Hoffman also reported two cases in 1924, and named the disease Kleine-Levin syndrome, also known as lethargy-bulimia syndrome. China has also reported this disease in recent years.
