Thiamine deficiency in infancy and epilepsy in seven children

What it found

Seven children who lacked thiamine as babies developed severe epilepsy that was hard to control.

All had lasting brain and movement problems five years later.

What they found

Studies in people

Seizures in infancy

All 7 babies had seizures when first seen by doctors. Six had electrical brain readings taken, and all showed slow background activity.

Seizures returned later

After 1 to 9 months without seizures, they came back in all 7 children. Electrical brain readings showed abnormal spikes in every child.

Hard to treat

Most seizure medicines did not work for these children. Four of the 7 still have seizures that cannot be controlled.

Lasting disabilities

All 7 children have learning difficulties and problems with movement. They also show signs of issues in the lower part of the brain.

What the authors conclude

  • Their findings suggest that a severe lack of thiamine in infancy can lead to epilepsy.

How it was done

The authors wanted to track the long-term outcomes of children who developed severe epilepsy after lacking thiamine as infants. The lack of thiamine came from a faulty soy-based formula.

They reviewed the medical records of 7 children, now aged 5 to 6 years old. These children had all lacked thiamine as babies and developed epilepsy. The team looked at their brain scans, electrical brain readings, and health over about 5 years.

What it can’t tell you

  • We summarised it from the abstract only.
  • This report follows a small group of children over time, so it can only show a link between early thiamine shortage and later epilepsy. It cannot prove that the shortage alone caused every problem seen years later.
