| What are some differences between a dementia and a delirium? |
|
Definition
1)The person with dementia alone is alert and does not have the disturbance in consciousness that is characteristic of delirium.
2) In delirium the onset of symptoms is much more rapid (i.e. over hours to days whereas in dementia the onset is typically more gradual.
3)Delirium symptom severity characteristically fluctuates during a 24 hour period, dementia symptom severity generally does not. |
