Read our Alzheimer Disease research guide →Researchers at Georgetown University are testing whether special blood tests and brain fluid tests can help doctors spot the early warning signs of memory loss and thinking problems, like those caused by Alzheimer's disease and other brain conditions. The study will collect blood samples (and optionally brain fluid samples) from about 1,000 people, along with brief thinking and memory tests, to see if these laboratory tests could someday help catch these conditions earlier, before symptoms become severe.
Right now, doctors can't easily detect memory and thinking problems until they've already started affecting a person's daily life. This study exists to see whether simple blood and brain fluid tests could identify these problems much earlier—possibly even before a person notices any changes—which could open the door to earlier treatment and better outcomes.

If you join, you'll come to the clinic at least once for an initial visit where researchers will ask about your health history, do brief memory and thinking tests, and draw blood (and optionally collect brain fluid). If you choose the longer-term option, you'll return to the clinic every 1–2 years depending on whether you have memory problems—those with normal thinking return every other year with phone check-ins in between, while those with memory concerns return yearly. The study continues until it ends, with no results shared back to you during this time.
