What Are Delusions?
Delusions are false beliefs that are strongly held, despite evidence to the contrary. In dementia, these beliefs can range from thinking that personal items are stolen to more complex notions like Capgras syndrome, where a patient believes a loved one has been replaced by an impostor. Delusions can be very distressing and impact the quality of life for both patients and caregivers.
Causes and Triggers
Delusions in dementia may arise from misunderstandings or misinterpretations due to cognitive decline. Factors such as poor vision, hearing loss, and memory deficits can exacerbate these false beliefs. Understanding the root causes is crucial for caregivers to provide appropriate support.
Managing Delusions
Approaches to managing delusions include both nonpharmacologic and pharmacologic strategies. Non-drug methods such as reassurance, structured routines, and minimizing stressors can be effective. In severe cases, medications may be necessary, but they should be used cautiously under medical supervision.
