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
Generally, Developmental delays can be related to:
Metachromatic leukodystrophy (MLD) or sulfatide lipidosis is a rare genetic disease that leads to the progressive destruction of the nervous system and causes lipids to accumulate in cells, especially in the brain, spinal cord, and nerves. This buildup is due to a deficiency of an enzyme called sulfatides, which helps break down lipids.
Ataxia-telangiectasia is a rare, inherited disorder that affects the nervous system, immune system, and other body systems starting in childhood, typically before age 5. It causes progressive difficulty with coordinating movements (ataxia), increased risk of cancer and infections. The disorder is due to mutations in the ATM gene, which controls the production of an enzyme that regulates cell division after DNA damage.
Spinal muscular atrophy is a group of genetic disorders where a person cannot control their muscle movement due to a loss of nerve cells in the spinal cord and brainstem. It causes muscle wasting and weakness.
Rickets Vitamin D deficiency
Related serious diseases
Sometimes, Developmental delays may be related to these serious diseases:
A type of epilepsy (recurrent seizures) that occurs in young children. These are more commonly called infantile spasms (IS) because they are seen most often in the first year of life, typically between ages 4 and 8 months. They often look like a sudden bending forward of the body with stiffening of the arms and legs lasting for one to two seconds; some children arch their backs as they extend their arms and legs. Spasms tend to happen when the infant wakes up, and often happen in many clusters, with hundreds of seizures per day. It results from damage to the developing brain, with various causes like chromosomal abnormalities (e.g. Down's syndrome), brain malformations, or brain infections.
