Psychomotor Development

Trisomy 21 And Psychomotor Development

Psychomotor development is generally slow. Acquisitions are hampered by constant hypotonia and ligamentous hyperlaxity. During the first months of life, they are affectionate babies, quiet, calm, crying little and sleeping a lot. They walk between 2 and three years old and talk about 4 to 5 years old.

From the age of 6-7, motor, intellectual and emotional instability is emerging. These disorders contrast with the previous phase of passivity.

The mental retardation is constant. Pedagogical acquisitions are often limited to the basics of reading and addition. The trisomic child is particularly sensitive to conditioning.
