The goal of this clinical trial is to determine if utilizing the Quest AD-Detect blood test, while patient's are hospitalized for a cognitive diagnosis (such as delirium or encephalopathy), will result in an earlier diagnosis of underlying Alzheimer's disease.
* Will this blood test have the ability to distinguish between Alzheimer's disease and other causes of cognitive impairment in the inpatient setting? * Neurology Clinic will complete a 6-month post-hospitalization follow up with patients who have had the Quest AD-Detect Alzheimer's Disease blood test completed while they were inpatient to discuss the risk assessment portfolio
