Who may be able to join

  • All participants:
  • Normal Education> 7 years

  • score on the scale of Beck <7 (depression scale)
  • signing the informed consent of the protocol in agreement with the Committee to Protect People
Show all 21Show fewer
  • Medical examinations, neurological, neuropsychological and neuroimaging depth in accordance with the specific inclusion and exclusion criteria for each population, that is to say:
  • Young healthy subjects aged between 18 and 44 years
  • Healthy subjects intermediate age: between 45 and 69 years
  • score on the Mattis Dementia Scale higher than 137, in order to exclude any potential dementia
  • Performance "normal" to test RI RL-16 (that is to say, not differing by more than 1.65 standard deviation from the norm for age and cultural level [see normative values published Van der Linden et al., 2004]), test conventionally used to assess the verbal episodic memory.
  • Healthy elderly subjects aged 70 and over, living at home
  • score on the Mattis Dementia Scale higher than 137, in order to exclude any potential dementia
  • Performance "normal" to test RI RL-16 (that is to say, not differing by more than 1.65 standard deviation from the norm for age and cultural level [see normative values published Van der Linden et al., 2004]), test conventionally used to assess the verbal episodic memory.
  • MCI patients: older than 50 years and recruited from memory clinics and meet the current criteria and recognized including amnestic MCI
  • memory complaint
  • targets deficits of episodic memory (lower performance of at least 1 standard deviation from the norm for age and cultural level to one or more (sub) episodic memory scores of diagnostic battery - cf. . Tables 1 and infra)
  • performance in the standards for age and cultural level in all tests of diagnostic battery measuring other cognitive functions as memory, including the evaluation of overall cognitive ability tests.
  • Alzheimer's patients: older than 50 years were recruited from the clinics and memory satisfying the standards NINCDS-ADRDA criteria for probable AD which include
  • abnormal global cognitive functioning and deficits in two or more cognitive domains identified by the diagnostic battery
  • mild to moderate AD (MMSE ≥ 18).

Who cannot join

  • Cognitive disorders of sudden onset (contrary to their slow and progressive onset in AD), which could reflect a stroke; a modified Hachinski ischemic score ≤ 2 (Loeb \& Gandolfo, 1983); history of head trauma with loss of consciousness for more than 1 hour, or encephalitis;
  • Chronic neurological disease, psychiatric, endocrine, hepatic, infectious;
  • A history of major illness (chronic lung disease, heart disorder, metabolic, hematologic, endocrine or immunological severe, cancer);
  • A medication that may interfere with the mnemonic or metabolic measures (psychotropics, hypnotics, anxiolytics, neuroleptics, anti-Parkinson, benzodiazepines, anti-inflammatory drugs, antiepileptics, antihistamines, analgesics and muscle relaxants central, as is usual The investigating doctor deems the annoying character for the study of the regular intake of certain medications). Taking anticholinesterase treatment will also be a criterion for non-inclusion.
  • Chronic intake of alcohol or drugs;

About this study

Investigators propose in this study to evaluate prospective memory (MP) in all its complexity as well as the processes, cognitive and brain, the underlying. Specifically, investigators propose to evaluate the evolution of the MP during normal aging and Alzheimer's disease (AD) to identify the cognitive and brain processes underlying this development. To do this, this study will have to include healthy subjects, 18 to 95 years, patients with Mild Cognitive Impairment (MCI) and patients with probable AD. All participants will undergo a series of examinations, both neuropsychological and brain imaging.

Questions about this trial

What is this clinical trial studying?

A study testing functional brain MRI and Neuropsychology tests in people with Alzheimer's Disease, run by University Hospital, Caen at 1 site in France.

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 21 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 13 Aug 2015. 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 France. 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?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

measuring the amplitude of the BOLD signal (Blood Oxygen Level Dependent) (time frame: baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Aug 2015.
