Insights
Pyridoxine-dependent seizures cause recurrent neonatal seizures resistant to standard treatments. Prompt response to pyridoxine administration confirms this rare condition, highlighting the importance of continued treatment.
Area of Science:
- Neurology
- Genetics
- Pediatrics
Background:
- Pyridoxine-dependent seizures (PDCS) are a rare genetic disorder causing severe neonatal seizures.
- These seizures are often refractory to conventional antiepileptic drugs.
Observation:
- A male infant experienced neonatal seizures initially responsive to anticonvulsants.
- Seizures recurred and became unresponsive to all anticonvulsant medications.
- The infant's seizures ceased upon administration of pyridoxine.
Findings:
- Recurrence of seizures after pyridoxine discontinuation confirmed the diagnosis.
- Pyridoxine administration effectively controlled seizures in this patient.
- The case underscores the critical role of pyridoxine in PDCS.
Implications:
- Early diagnosis and treatment with pyridoxine are vital for preventing neurological damage.
- Pyridoxine-dependent seizures require specific diagnostic and therapeutic approaches.
- Increased awareness among clinicians can improve outcomes for affected infants.
Abstract:
Pyridoxine-dependent seizures is a rare cause of recurrent seizures in neonatal period and resistant to most of the antiepileptic medications, but respond to administration of pyridoxine. We report a male infant who had neonatal seizures which were initially responsive to anticonvulsants and later became unresponsive and presented at 45 days of life with seizures. These seizures were not responding to any anticonvulsant but responded to pyridoxine. After discharge parents inadvertently stopped pyridoxine and the infant presented with seizures once again. These seizures were promptly controlled with readministration of pyridoxine confirming the diagnosis of pyridoxine-dependant seizures.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
