Clinical Trial Protocol: Alzheimer's Dementia Underlying Encephalopathy

This trial is testing a blood test called Quest AD-Detect on patients who are already hospitalized with sudden confusion or cognitive symptoms. The question is whether this blood test can spot underlying Alzheimer's disease earlier, while the patient is still in the hospital, rather than missing it during an acute illness. This is a Phase NA study, meaning it is a practical diagnostic evaluation rather than a drug or treatment trial.

You may qualify if

  • Ages 60 to 90 years old
  • No prior diagnosis of dementia
  • Currently hospitalized with cognitive diagnosis, including but no limited to; delirium, encephalopathy, etc. thought to be secondary to a toxic/metabolic state

You're excluded if

  • Age under 60 years
  • Prior diagnosis of dementing illness or other organic etiology to cognitive impairment
