You are probably describing two different issues. First, snoring by itself is not a disorder. 50% of the population snores. However, it MAY be a symptom of a sleep disorder, such as sleep apnea. Second, the leg movements.....well this also may be several different things. Some normal and some 'abnormal'. If they occur periodically, like every 20-40 seconds during the night, this may be PLMS, periodic leg movements during sleep. These may or may not be a 'disorder'. It depends on your symtpoms. For more information, check out the American Sleep Association's page on periodic leg movement disorder, and periodic leg movements during sleep. Also, as always, talk to your doctor....Good Luck.
