The patient might become increasingly confused about what time it is, where he or she is and the identity of close and familiar people. These are due to changes in body metabolism.
Your loved one may become restless. He or she may see things that are not there or pull at the bed linen. Both are due to the decreased oxygen circulation to the brain and the change in the body’s metabolism.
Remind your loved one of who is in the room. Talk to him or her calmly and reassuringly. Sitting next to the bed and holding a hand is sometimes helpful. React calmly so as not to startle or frighten the patient.
