Why people with dementia sleep so much — and when it's normal versus a sign of something else

Many do, although sleep patterns vary. Some people sleep more during the day because they are tired, less active, or affected by the disease itself. Others have broken sleep, wake up often at night, or become more restless in the evening. Changes in sleep can also be caused by medicines, pain, illness, or low activity. Good light during the day, regular routines, and limited daytime naps may help. Sudden sleep changes should be checked, because they can signal a treatable problem.
