Dendrites are tree-like structures with tiny spines specialized to receive excitatory synaptic transmission. Spino-dendritic plasticity, driven by neural activity, underlies the maintenance of neuronal connections crucial for proper circuit function. Abnormalities in dendritic morphology are frequently seen in epilepsy. However, the exact etiology or functional implications are not yet known. Therefore, to better comprehend the structure-function significance of this dendritic pathology in epilepsy, it is necessary to identify the common spino-dendritic disturbances present in both human and experimental models. Here, we describe the dendritic and spine structural profiles found across human refractory epilepsy as well as in animal models of developmental, acquired, and genetic epilepsies.

There is a reciprocal relationship between epilepsy and reproductive endocrine disorders. Seizures and anti-seizure medications (ASMs) can contribute to reproductive and endocrine dysfunction and reproductive dysfunction may exacerbate seizures. Epilepsy via neuroendocrine mechanisms affects the hypothalamic–pituitary-ovarian (HPO) axis, disrupting the regulation of gonadotropin secretion, and resulting in dystrophic effects on the ovaries and early menopause. Anti-seizure medications have endocrine-related side effects on sexual function and bone health. Long-term use of ASMs may result in menstrual irregularities, sexual dysfunction, anovulatory cycles, polycystic ovaries, and reduced fertility. Some ASMs also interfere with bone metabolism. Epilepsy patients treated with ASMs are at risk for bone loss and fractures. This article explores the endocrine and hormonal effects of seizures and ASMs.

This brief review summarizes presentations at the Temporal Lobe Club Special Interest Group session held in December 2022 at the American Epilepsy Society meeting. The session addressed newer methods to treat temporal epilepsy, including methods currently in clinical use and techniques under investigation. Brief summaries are provided for each of 4 lectures. Dr Chengyuan Wu discussed ablative techniques such as laser interstitial thermal ablation, radiofrequency ablation, focused ultrasound; Dr Joon Kang reviewed neuromodulation techniques including electrical stimulation and focused ultrasound; Dr Julia Makhalova discussed network effects of the aforementioned techniques; and Dr Derek Southwell reviewed inhibitory interneuron transplantation. These summaries are intended to provide a brief overview and references are provided for the reader to learn more about each topic.
