|Feeling delirious or delirium is a state of confusion that is characterized by a change in mental status that affects cognitive abilities (mental tasks) and reduces conscious awareness. It also tends to develope very rapidly.
It usually takes a few hours to a few days to manifest and when it does, the individual is often left feeling confused, disoriented and unaware of their surroundings. It can affect speech, memory, attention span, emotions and personality as well as other cognitive capacities, which can be very distressing for both the sufferer as well as loved ones.
The good news is that all these symptoms are usually temporary, and in most cases only last between a few hours and a few days, depending on the cause and treatment. While Delirium itself does not cause death, it is sometimes a symptom of a serious medical condition, such as a very high fever or severe head injury.
