Answer:
The correct answer is delirium.
Explanation:

It makes an individual difficult to remember, sleep, think, to pay attention, and several other consequences. One might experience delirium post-surgery, at the time of alcohol withdrawal, or with dementia.
However, the condition is generally impermanent and can be cured efficiently. Delirium influences the emotions, mind, sleep patterns, and control of muscles. One may find it tough to concentrate or feel confused regarding his or her locations. One may also move gradually or briskly than generally, and may even encounter with mood swings.
