About the symptom

It refers to a child who has not gained the developmental skills expected of him or her, compared to others of the same age.

Possible causes

  • Sleep disorder

    Sleep disorders are conditions that affect the quality, timing, or duration of your sleep, impacting your ability to function when you're awake. There are many types of sleep disorders, including disturbances in sleep quality or quantity, excessive daytime sleepiness, abnormal behaviors during sleep, sleep disorders related to mental disorders, and more.

  • Tics

    A condition where patients experience a strong, almost irresistible urge to perform an action like shaking their head, squeezing their eyes, or making a particular noise. Most tics improve with the transition to adulthood, but may persist for some. Known triggers include sleep deprivation, excitement, and stress.

  • Rickets Vitamin D deficiency

    Rickets is the softening and weakening of bones in children, usually due to an extreme and prolonged vitamin D deficiency. Vitamin D helps the body absorb calcium and phosphorus from food. Insufficient vitamin D makes it difficult to maintain proper calcium and phosphorus levels in bones, which can cause rickets.

  • Telangiectasia ataxia
  • Spinal muscular atrophy
  • Metachromatic leukodystrophies

Related serious diseases

  • West syndrome (infantile spasm)

    A type of epilepsy (recurrent seizures) that occurs in young children. It results from damage to the developing brain, with various causes like chromosomal abnormalities (e.g. Down's syndrome), brain malformations, or brain infections.
