💬In plain words
What the trial is, and whether it could suit you
Background:
About 5 million adults in the U.S. have Alzheimer s disease or another adult-onset neurodegenerative disorder. Many studies have found that inflammation in the brain contributes to these diseases. Researchers want to find a better way to measure this inflammation.
Objective:
To learn whether COX-1 and/or COX-2 is elevated in the brains of individuals with neurodegenerative brain disease compared to healthy volunteers.
Eligibility:
Adults age 18 years and older in good general health who have an adult-onset neurodegenerative dementia, such as AD, FTD, corticobasal syndrome, Huntington s disease, or MCI, ALS and healthy adult volunteers enrolled in protocols 01-M-0254 or 17-M-0181.
Design:
Participants will be screened with medical history, physical exam with vital signs, and lab tests. They will have a neuropsychological testing. Their heart function will be measured.

📋 Eligibility rules (as published)
* INCLUSION CRITERIA:
Patients: In order to be eligible to participate in this study, patients must meet all of the following criteria:
1. Aged 18 or older.
2. Be able (or have their Legally Authorized Representative (LAR) be able) to understand the study and be willing to sign a written informed consent document.
3. Have been diagnosed by a neurologist or psychiatrist with MCI, ALS, PD, or an adult onset neurodegenerative dementia, such as AD (including amyloid negative subjects), FTD, corticobasal syndrome, or Huntington s disease.
4. Be in good general health as evidenced by medical history and physical examination.
5. Have their radial artery pulse checked for the presence of adequate ulnar collateral flow and the absence of any metal or foreign objects in both wrists.
6. Agree to adhere to the lifestyle considerations.
Healthy volunteers: In order to be eligible to participate in this study, healthy volunteer subjects must meet all of the following criteria:
1. Aged 18 or older.
2. Female participants of childbearing potential must be using a medically acceptable means of contraception
3. Able provide informed consent.
4. Be in good general health, as evidenced by medical history and physical examination, and have no cognitive impairment.
5. Be enrolled in 01-M-0254, The Evaluation of Participants with Mood and Anxiety Disorders and Healthy Volunteers or 17-M-0181, Recruitment and Characterization of Healthy Research Volunteers for NIMH Intramural Studies
6. Have their radial artery pulse checked for the presence of adequate ulnar collateral flow and the absence of any metal or foreign objects in both wrists.
7. Agree to adhere to the lifestyle considerations.
EXCLUSION CRITERIA:
Both patients and healthy volunteers who meet any of the following criteria will be excluded from participation in this study:
1. Clinically significant abnormalities on EKG or laboratory testing. This includes CBC and acute care panel (Na, K, Cl, CO2, creatinine, glucose, urea nitrogen). Any lab value that is two-times the upper limit or even lower values in the investigator s judgment. Creatinine level \>1.3 mg/dL
2. Subjects should not have taken Non-Steroidal Anti-Inflammatory Drugs (NSAID) for two weeks prior to the PET scan. Aspirin, corticosteroids (with the exception of skin products), or immunosuppressants (e.g., methotrexate) must not have been taken in the prior month.
3. Contraindications to ketoprofen, such as hypersensitivity to ketoprofen or history of upper or lower gastrointestinal bleeding.
4. Have other major neurological or medical diseases that may cause cognitive dysfunction, such as structural brain diseases, metabolic diseases, paraneoplastic syndromes, infectious diseases, or other significant neurological abnormalities.
5. Have an unstable medical condition that, in the opinion of the investigators, makes participation unsafe (e.g., an active infection or untreated malignancy).
6. Are unable to travel to the NIH.
7. Have recent exposure to radiation related to research (e.g., PET from other research) that, when combined with this study, would be above the allowable limits.
8. Have an inability to lie flat and/or lie still on the camera bed for at least two hours, including claustrophobia, overweight greater than the maximum for the scanner, and uncontrollable behavioral symptoms, which will be screened by an interview with the patient and/or caregiver during the screening visit.
9. Participants must not have substance use disorder or alcohol use disorder. However, alcohol or cannabis use by themselves are not exclusion criteria, unless that use impairs function of daily life.
10. Participants should not be under treatment with Aduhelm, nor should they have been treated in the past.
11. Are unable to have an MRI scan (e.g., because of pacemakers or other implanted electrical devices, brain stimulators, dental implants, aneurysm clips (metal clips on the wall of a large artery), metallic prostheses (including metal pins and rods, heart valves, and cochlear implants), permanent eyeliner, implanted delivery pumps, shrapnel fragments, or metal fragments in the eye).
12. Pregnancy
13. HIV infection
14. Be NIMH staff or an NIH employee who is a subordinate/relative/co-worker of the investigators.
