Some people have difficulty sleeping.
A change in one's sleep pattern, much more of it or much less of it, is a classic sign of depression. Little sleep and a very high activity level while awake could be a sign of mania. If you see this, report it to the appropriate health care professional so a complete evaluation can be made. Due to daytime fatigue in advanced HD, some folks accidentally fall into a cycle of napping during the day and then being unable to fall asleep at night. You can usually find the right balance between conserving energy during the day and being tired enough to sleep through the night.
