Age, gender, andchronic illnesses are not generally associated with delirium triggers.Dementiais impairment of intellectual function, memory, and language with alteration in behavior and can becaused by trauma, vascular disease, infection, and progressive neurodegeneration.Alzheimer Disease (A)is the most common chronic, irreversible dementia.Seizure Types- pages 550-555Seizuresrepresent abnormal, excessive hypersynchronous discharges of cerebral neurons with transientalterations in brain function. Seizures may be generalized or focal.A sudden, explosive, disorderlydischarge of cerebral neuronsdescribes aseizure.
