Seizure exacerbation with anti-seizure medications in adult patients with epilepsy.

There are numerous reports of seizure exacerbation related to specific anti-seizure medications (ASMs); however, a quantitative analysis with clearly defined parameters for seizure exacerbation in an outpatient setting is lacking. This retrospective study examines adult patients starting a single ASM and follows patient outcomes over the course of treatment, with quantitative evaluation of the incidence of paradoxical seizure exacerbation. In this study, outpatient encounters with five epileptologists at the Baylor College of Medicine Comprehensive Epilepsy Center were evaluated over a 10-month period.

Early postnatal in vivo gliogenesis from nestin-lineage progenitors requires cdk5.

The early postnatal period is a unique time of brain development, as diminishing amounts of neurogenesis coexist with waves of gliogenesis. Understanding the molecular regulation of early postnatal gliogenesis may provide clues to normal and pathological embryonic brain ontogeny, particularly in regards to the development of astrocytes and oligodendrocytes. Cyclin dependent kinase 5 (Cdk5) contributes to neuronal migration and cell cycle control during embryogenesis, and to the differentiation of neurons and oligodendrocytes during adulthood.
