Brief Summary

TriAL21 study is an interventional, open, one arm, prospective, national and single center study. A total of 200 patients with Down syndrome, aged 35 years and over, without diagnosis of Alzheimer's disease will be enrolled into the study. Participating centre is Institut Jérôme Lejeune; outpatient's clinic dedicated to treating patients with cognitive deficiencies of genetic origin including patients with Down syndrome.

Eligibility Criteria

Age35 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female 35 years old and over ;
  • Clinical diagnosis of Down syndrome ;
  • Patient attending the geriatric outpatient clinic
  • Patient without diagnosis of Alzheimer's disease;
  • Patient covered by social welfare;
  • Patient himself or legal guardian/representative willing and consenting to participate to the study by giving written informed consent;
  • Patients must have a parent, or / and other reliable caregiver who agrees to accompany him/her to all visits, provide information about the patient as required by the protocol. The parent or caregiver must be a constant and reliable informant with sufficient contact with the patient to have detailed knowledge of the patient's adaptive functioning in order to be able to complete the assessments accurately.

You may not qualify if:

  • Patient presenting a contraindication to MRI in particular carrier of metal implants such as pacemakers;
  • Patient presenting a serious, severe or unstable pathology (left to the investigator's discretion) whose nature may interfere with the evaluation parameters;
  • Patient without Alzheimer's disease diagnosis but with severe dementia;
  • Participation in other clinical trials in the last 3 months prior to the study;
  • Pregnant woman.
