Confusion
There are different degrees of confusion, and in dementia they all depend on the severity of the patient’s memory problems. During early phases, when they start experiencing mild memory problems, they become confused because they lose track of what happened in the past or have trouble remembering details about their past. As the disease advances, patients may also confuse space and time, and strongly believe they are in other place and stuck in their memories about their past.
Confusion in patients with Alzheimer is very severe in a late phase of the disease. It ends up affecting the relationship of the patient with his relatives, and causes emotional breakdowns in their loved ones as they realize the patient is no longer able to recognize them.
