Ring chromosome 14 is a very rare chromosomal disorder. Infants and children with ring chromosome 14 often have psychomotor retardation, physical and intellectual retardation, and epilepsy.

Children under 6 years old are at the age of rapid physical, mental and motor development. Physical growth is assessed and monitored through biological indicators and energy charts. In addition, psychological tests are required to assess and monitor psychomotor development. Currently, the Denver Test is applied by many countries around the world and is considered the first tool to assess psychomotor development in children.

Psychomotor retardation is a slowing or hindering of a person's mental or physical activities, often characterized by slow thinking or slow body movements. So what are the causes and how is this disease diagnosed?
