Details and patient eligibility

About

Currently, the instruments used in translational studies related to cognition have proved to be inaccurate. For this reason, the objective of this study is to evaluate whether the Bordeaux Maze Test has adequate psychometric properties and is valid for its use to compare trials tested in preclinical (animal) studies and clinical population with Down syndrome. Specifically, it is intended to study the domains of memory (relational memory) and executive functions (work memory), both relevant in the cognitive functioning of the population with Down syndrome.

Subjects with past history of seizures from primary causes (such as West syndrome and Lennox-Gastaut syndrome) or secondary causes.
Clinical history of moderate or severe Obstructive Sleep Apnea (OSA) as defined by Apnea-Hypopnea Index (AHI) (>15 events per hour not well controlled by positive airway pressure therapy with stable settings) for at least 3 months prior to screening visit.
Alcohol and/or substance use disorder in the past year.
Concomitant disease or condition or any clinically significant finding at screening that could interfere with the conduct of the study, or that would, in the opinion of the investigator, could lead to an unacceptable risk to the subject in this study.
