Step-by-step explanation:
Confusion, restlessness, and agitation may result from a variety of factors including lack of sleep, medication side effects, high levels of stress, or other health conditions. These symptoms can significantly impact an individual's daily life and well-being. When it comes to medication, it's widely understood that side effects can vary greatly, and the mental and behavioral symptoms mentioned can indeed be a consequence of how certain drugs interact with the body. Medications, particularly those affecting the brain and nervous system, can alter mood, perception, and behavior, potentially leading to increased agitation, anxiety, and sleep problems.
