Why is the ketogenic diet beneficial in PDHc deficiency?

Ketogenic diet provides ketone bodies as alternative fuel bypassing the PDHc block; particularly beneficial for brain energy metabolism, reducing seizure frequency and improving neurodevelopment.

How does thiamine supplementation help in some PDHc cases?

Thiamine pyrophosphate is a cofactor for E1 subunit of PDHc; high-dose thiamine (10-100 mg/kg/day) can partially restore activity in thiamine-responsive variants.

What brain MRI findings suggest PDHc deficiency?

Corpus callosum agenesis or dysgenesis, basal ganglia abnormalities (similar to Leigh syndrome), periventricular cysts, and delayed myelination are characteristic MRI patterns.

Is dichloroacetate effective for PDHc deficiency?

DCA reduces lactate by stimulating PDHc; short-term improvement is seen, but peripheral neuropathy limits long-term use; used as bridge to other therapies or in mild forms.

Pyruvate Dehydrogenase Complex Deficiency Assessment

Assesses pyruvate dehydrogenase complex (PDHc) deficiency severity using plasma lactate/pyruvate ratio, CSF lactate, brain MRI findings, and ketogenic diet adequacy monitoring.
