Insights
Maternal nutritional vitamin B12 deficiency can cause infantile spasms in infants. Prompt treatment with vitamin B12, adrenocorticotropic hormone (ACTH), and phenobarbital effectively resolved symptoms in two infants, highlighting its role as a treatable cause.
Area of Science:
- Pediatric Neurology
- Nutritional Neuroscience
- Developmental Pediatrics
Background:
- Nutritional vitamin B12 deficiency in infants, often due to maternal deficiency, can lead to severe hematological and neurological issues.
- While epilepsy is a rare manifestation, the neurological underpinnings of infantile vitamin B12 deficiency are not fully understood.
- Limited English literature exists on the specific link between infantile spasms and vitamin B12 deficiency.
Background:
In developing countries, nutritional vitamin B12 deficiency in infants because of maternal deficiency often causes hematological and neurological disorders. However, epilepsy is a rare manifestation of vitamin B12 deficiency. The biological basis for the observed neurological symptoms of infantile vitamin B12 deficiency remains uncertain. There are only a few reports in the English literature regarding the relationship between infantile spasms and vitamin B12 deficiency.
Patients:
We report two unrelated infants having infantile spasms associated with vitamin B12 deficiency related to maternal nutritional deficiency.
Results:
During the first month of adrenocorticotropic hormone (ACTH), phenobarbital, and vitamin B12 treatments, both infants' abnormalities resolved. After 3 months, electroencephaography was completely normal. ACTH and phenobarbital treatments were ended. The children are disease-free 9 months after the treatment.
Conclusions:
We suggest that vitamin B12 deficiency should be considered in the differential diagnosis of infantile spasms as a treatable cause, especially with a history of maternal nutritional deficiency.

Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups.
