What is a common psychological response patients may experience after anesthesia?

Patients often experience confusion or delirium after anesthesia, especially older adults. This reaction is primarily due to the effects of the anesthetic agents on the central nervous system, which can lead to altered mental status. In older populations, the brain may be more sensitive to these effects, resulting in a higher incidence of postoperative confusion.

This confusion can manifest as disorientation, difficulty understanding surroundings, or challenges in recognizing familiar individuals. The brain's recovery from anesthesia can vary widely among individuals, and age-related factors, such as cognitive reserve and pre-existing conditions, can further influence the degree of confusion experienced.

While some patients might report feelings of happiness or increased energy upon waking, these responses are not as common as confusion or delirium, particularly in vulnerable populations like the elderly.
