Revisiting the concept that interictal implies asymptomatic: Pulse wave amplitude drops uncover autonomic responses during generalized paroxysmal fast activities

Epilepsia, EarlyView.
Abstract Objective Interictal electroencephalographic (EEG) activities are generally considered asymptomatic. Pulse wave amplitude drop (PWAD) is a marker of autonomic nervous system (ANS) reactivity linked to cardiovascular risk. Generalized paroxysmal fast activity (GPFA) is a major EEG pattern in different epileptic conditions.

Timing is everything: The effect of early‐life seizures on developing neuronal circuits subserving spatial memory

Epilepsia Open, EarlyView.
Abstract Spatial memory, the aspect of memory involving encoding and retrieval of information regarding one's environment and spatial orientation, is a complex biological function incorporating multiple neuronal networks. Hippocampus‐dependent spatial memory is not innate and emerges during development in both humans and rodents.

Soluble Nanomedicine Against Soluble Neurosensitizers to Effectively Relieve Osteoarthritis Pain and Joint Damage

Exploration, EarlyView.
Osteoarthritis pain arises not only from joint damage but also from inflammation, abnormal bone changes, and excessive nerve activation inside the joint. In this study, we developed an injectable nanomedicine, LAC, that responds to the acidic environment of osteoarthritic joints to locally release two approved drugs, reducing inflammation, limiting ...
