Fudgin [204]

An unexpected variation in the brain, which leads to emotional disruption and mental confusion is known as delirium. 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.

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.  

Thus, it can be concluded that in the given case of 8 year Jed, who had undergone surgery is not able to concentrate on anything and is feeling confused due to a condition known as delirium.
