Confused states related to this condition are usually brief and changeable.  The causes of confusion can be diverse.

  Loss of oxygen and be one of many causes.  It can also be caused by poisoning, or diseases not associated with the brain at all. Infections can also elicit Delirium to set in.  Pneumonia can also be a cause, since this illness deprives the brain of oxygen.

The conditions which cause the Delirium will determine the treatment necessary to resolve it.  The patient should be kept safe and comfortable while being evaluated, and until the episode passes.  Certain medicines may actually worsen the patient’s mental state, and these should be avoided.  Any conditions which contribute to a lack of oxygen to the brain should be treated.  While Delirium is present, treatment may be necessary to control any negative and dangerous behaviors that the patient may be experiencing, such as outrage or any violent actions.  Normally patients experience a complete recovery.
