Delirium vs. Dementia
Delirium and dementia can often be confused with one another. Delirium is an acute confusional state, which can typically be reversed if the underlying cause is treated. Dementia is when two or more brain functions become impaired, such as judgment and memory loss. The most common similarities between the two illnesses are confusion, agitation, and delusions. However, many characteristics can determine which is which.
Onset - Delirium begins abruptly, while dementia generally progresses over time.
Course - Delirium is typically temporary and reversible, while dementia is rather permanent and progressively gets worse over time.
Cause - Delirium can be caused by medications and infections. Dementia presents itself when there are anatomic changes in the brain.
Symptoms - Delirium and dementia share symptoms such as changes in mood and disorientation. However, dementia patients struggle more with memory loss, the ability to carry out daily living activities, and problem-solving.
