Trial summary

Background: Individuals who demonstrate symptoms of Alzheimer s disease, such as progressive memory loss, may be eligible to participate in National Institutes of Health research studies. However, other physical and psychological conditions may produce symptoms similar to those of Alzheimer s disease. Read more about this study

About this study

Background:

  • Individuals who demonstrate symptoms of Alzheimer s disease, such as progressive memory loss, may be eligible to participate in National Institutes of Health research studies. However, other physical and psychological conditions may produce symptoms similar to those of Alzheimer s disease. To determine whether a patient meets the eligibility criteria to participate in a research protocol, researchers must perform a series of diagnostic tests and procedures.
  • These evaluations are designed to evaluate a participant s general medical condition (for example, blood tests and neurological exams) and to confirm a diagnosis or rule out an individual for consideration. They maximize the safety for participants in studies conducted at the National Institutes of Mental Health.

Objective:

  • To determine the eligibility of individuals for active Alzheimer s disease protocols.

Eligibility:

  • Individuals 45 years of age and older who have been having memory problems that have been getting worse with time and have been interfering with everyday life.

Design:

  • Required tests and procedures for various research studies may include the following:
  • Medical history and physical examination, including a psychiatric evaluation.
  • Neuropsychological tests to test memory, mood, concentration, and thought processes.
  • Blood and urine tests.
  • Imaging studies (X-rays, magnetic resonance imaging (MRI), computerized tomography (CT), positron emission tomography (PET)).
  • Additional blood samples and MRI data for future use.
  • After all eligibility assessments are complete, participants may be offered participation in one or more research protocols
Read the detailed description

Objective: To provide a mechanism for recruitment and screening of AD patients for inclusion into studies conducted at the National Institutes of Health. To provide data from MRI and [18F]FDG and PIB PET imaging from healthy volunteers to compare to that from AD patients. To provide longitudinal data from MRI and [18F]FDG and PIB PET imaging from both AD patients and healthy volunteers.

Study population: Patients with signs and symptoms of Alzheimer s disease. Healthy age-matched volunteers.

Design: Patients with signs and symptoms of Alzheimer s disease will be recruited from the community using advertisements and through communication with neurologists, psychiatrists, and general practitioners in the community. Patients will come to the NIH for an evaluation that may include medical and neurological evaluation, laboratory testing, brain MRI, neuropsychological evaluation, and brain imaging with [18F]fluorodeoxyglucose ([18F]FDG) and carbon-11 labeled Pittsburgh Compound B (PIB) PET. The focus of this protocol will be on assisting with the diagnosis of AD vs. another cause of memory impairment. Eligible patients will be offered participation in other protocols with the Molecular Imaging Branch. Eligible patients may also be referred to other studies at the NIH. Patients will not be offered treatment or long-term follow-up in this protocol. Age matched healthy volunteers will undergo brain imaging with MRI and with [18F]FDG and PIB PET. Healthy volunteers and patients who meet diagnostic criteria for AD will be asked to repeat study procedures after an interval of at least one year but no more than 5 years.

Outcome measures: Results from medical and neurological evaluation, neuropsychological testing, laboratory tests, and brain MRI will be used to determine if patients meet NINDS criteria for probable Alzheimer s disease. In patients who undergo brain imaging with [18F]FDG and PIB PET, PET data will be used for investigational purposes in subjects who participate in other protocols with the Molecular Imaging Branch. Results from brain imaging from healthy volunteers will be used to compare to that from AD patients. [18F]FDG and PIB PET may also be useful for determining if patients meet criteria for probable Alzheimer s disease.

Questions about this trial

What is this clinical trial studying?

An observational study of Alzheimer's Disease, run by National Institute of Mental Health (NIMH) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00955422, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jul 2018.
