Folate metabolism and problem behaviour in mentally handicapped epileptics

Area of Science:

• Neurology
• Nutritional Neuroscience

Background:

• Epilepsy is a common neurological disorder.
• Antiepileptic drugs (AEDs) are widely used for epilepsy management.
• Nutritional deficiencies, particularly in folate and vitamin B12, can occur in individuals with epilepsy.

Purpose of the Study:

• To investigate serum folate and vitamin B12 levels in institutionalized adults with epilepsy compared to non-epileptic controls.
• To examine the impact of antiepileptic medication, specifically phenytoin, on these nutrient levels and behavioral ratings.

Main Methods:

• A case-control study involving 32 institutionalized adults with epilepsy on medication and 32 non-epileptic controls.
• Serum levels of folate and vitamin B12 were measured.
• Behavioral ratings were assessed for both groups.

Main Results:

• Epileptic individuals exhibited significantly lower serum folate levels compared to controls.
• No significant differences were found in serum vitamin B12 levels or behavioral ratings between the two groups.
• Within the epileptic group, individuals receiving phenytoin had significantly lower serum folate levels than those not on phenytoin.

Conclusions:

• Epilepsy and its treatment, particularly with phenytoin, may be associated with folate deficiency.
• Further research is warranted to explore the clinical implications of these findings and optimize nutritional management in epileptic populations.
