Medical evaluations of incidence, nature, severity and causality of Adverse Events and Serious Adverse Events (SAE).
From day -5 to day 252 (through study completion)
Safety Outcome Measure: Number of participants with treatment-related adverse events with supporting evidence with blood analysis: Changes in liver function
The finding of an elevated alanine transaminase (ALT) or aspartate transaminase (AST) (\>3xULN), elevated total bilirubin (\>2xULN)
Days -5, 5, 42, 84, 126, and 168.

76 participants (actual enrollment reported by the registry).
Effect of Neuro Developmental Therapy in Infants With Down Syndrome
Days -5, 42, 84, 126, and 168.
Safety Outcome Measure: Number of participants with treatment-related adverse events with supporting evidence with blood analysis: Changes in renal function
Serum creatinine will be measured at various time points and an increase exceeding x1.5 ULN (upper limit of normal values) that is confirmed by a repeat testing within 3 days.
Days -15, 84, and 168
Safety Outcome Measure: Number of participants with treatment-related adverse events with supporting evidence with Electroencephalography (EEG): Clinical significant changes in cerebral activity
Electroencephalogram recording to detect epileptiform abnormalities and/or seizure activity and/or pro-convulsive effects in pediatric participants, enabling a deeper understanding of the pharmacological effects of the intervention.
Days -15, 84, and 168
Safety Outcome Measure: Measure: Number of participants with treatment-related adverse events with supporting evidence with Electrocardiogram: Clinical significant changes in QTcF
A QTcF (Fridericia's correction) value (mean of the three measurements) exceeding 500 ms when confirmed in repeat measurement within 15-30 minutes will be recorded as SAE. A QTcF value exceeding a change from screening (mean of three time-matched measurements) of 60 ms when confirmed in repeat measurement within 15-30 minutes will be recorded as SAE.
Days -56 and 168
Safety Outcome Measure: Measure: Number of participants with treatment-related adverse events with supporting evidence with Echocardiogram: Clinical significant changes in size of the chambers of the heart.
Doppler echocardiogram is used to look at how blood flows through the heart chambers, heart valves, and blood vessels. The movement of the blood reflects sound waves to a transducer. The ultrasound computer then measures the direction and speed of the blood flowing through heart and blood vessels.
Days -56 and 168
Safety Outcome Measure: Measure: Number of participants with treatment-related adverse events with supporting evidence with Echocardiogram: Clinical significant changes in pumping function of the heart.
This measure is known as an ejection fraction or EF.
Days -56 and 168
Cognitive Outcome Measure : IDD-CHILD Battery. Cognitive changes in Expressive language
Days -15, 168 and 252
Cognitive Outcome Measure : IDD-CHILD Battery. Cognitive changes in Receptive language
Days -1,168 and 252
Cognitive Outcome Measure : IDD-CHILD Battery. Cognitive changes in Memory and Learning
Days -1,168 and 252
Cognitive Outcome Measure : IDD-CHILD Battery. Cognitive changes in Working Memory (WM)
Days -1,168 and 252
Cognitive Outcome Measure : IDD-CHILD Battery. Cognitive changes in Verbal Fluency (VF)
Days -1,168 and 252
Exploratory Outcome: Efficacy Biomarkers analysis in plasma
Baseline, months 3 and 6
Exploratory Outcome: Blood folate concentration
Months -1, 3 and 6
Exploratory Outcome Targeted metabolomics
Months -1, 3 and 6
