Antiepileptic drugs and the developing brain

A M Kaindl et al. Cell Mol Life Sci. 2006 Feb.

Abstract

Epilepsy is the most common neurological disorder in young humans. Antiepileptic drugs (AEDs) which are used to treat seizures in infants, children and pregnant women can cause cognitive impairment, microcephaly and birth defects. Ion channels, neurotransmitters and second messenger systems constitute molecular targets of AEDs. The same targets regulate brain processes essential both for propagation of seizures and for learning, memory and emotional behavior. Thus, AEDs can influence brain function and brain development in undesired ways. Here we review mechanisms of action of AEDs, examine clinical evidence for their adverse effects in the developing human brain, and present studies on cognitive and behavioral effects in animal models. Furthermore, we discuss mechanisms responsible for adverse effects of AEDs in the developing mammalian brain, including interference with cell proliferation and migration, axonal arborization, synaptogenesis, synaptic plasticity and physiological apoptotic cell death.
