Delirium, often referred to as frenzy, is a state of severe confusion and disorientation that can occur suddenly. It is characterized by an inability to focus, changes in perception, and fluctuating levels of consciousness. Delirium can be caused by various factors, including infections, substance withdrawal, or metabolic imbalances. This condition is particularly common in older adults and can lead to significant distress for both the individual and their caregivers. Treatment typically involves addressing the underlying cause, ensuring a safe environment, and providing supportive care to help the person regain clarity and stability.
