F05: Delirium, not induced by alcohol and other psychoactive substances

F05.8: Other delirium

With delirium, one is less aware than normal. The memory also often changes temporarily. One may be very restless and have a strong desire to move. One may also no longer know who or where one is. The senses and the sleep-wake cycle may be very mixed up. There is a physical reason for this. For example, it can be caused by damage to the brain, by medication or other disorders. A delirium like this may occur after an operation, for example.
