If your loved one is struggling from abnormal sleep issues and his or her health is deteriorating, it is strongly recommended that you talk to his or her doctor about their sleeping patterns.
This is not typical. You need to determine what is causing your loved one to sleep for such extended periods of time without eating or drinking.
It isn’t unusual for there to be a change in sleeping patterns with dementia, but the length of time your loved one is sleeping is a concern.
What strategies you should use to keep our loved one up more will depend on what is causing this person to sleep more. With some people with dementia, they simply need appropriate activities to keep them awake and stimulated.
However, without knowing the cause of this person’s extended sleeping, it is impossible to suggest things to help keep him awake. It is recommended you seek medical attention quickly.
