“…Moreover, PET imaging revealed that ECT treatment transiently changes local cerebral blood flow, leading to an increase in the brain stem, diencephalon and basal ganglia for instance [ 67 ]. Yet, the so-called blood-brain barrier (BBB) constitutes a barrier controlling the molecular exchange between the circulating blood and the brain parenchyma (reviewed, e.g., by Ilbay and colleagues [ 68 ]). Roughly speaking, the BBB prevents under physiological conditions the diffusion of large and/or hydrophilic molecules but allows for the passage of hydrophobic molecules and substances having their specific transporters, for example, glucose.…”

“…Roughly speaking, the BBB prevents under physiological conditions the diffusion of large and/or hydrophilic molecules but allows for the passage of hydrophobic molecules and substances having their specific transporters, for example, glucose. Neuropathological disturbances like stroke or epileptic seizure, can lead to leakage of this barrier [ 68 ]. Under these conditions, various circulating molecules can diffuse out of the blood vessels and thereby change the microenvironment of the brain parenchyma and of the neurogenic niches.…”

“…Existen datos experimentales y clínicos que indican que las crisis epilépticas producen alteraciones significativas en la permeabilidad de la BHE, se ha observado que estas alteraciones son reversibles y confinadas a áreas anatómicas encefálicas limitadas. Las crisis epilépticas pueden producir incremento en la permeabilidad cerebro capilar, lo que induce alteraciones en la función cerebrovascular que involucra una interacción entre factores del sistema global y fenómenos moleculares más localizados que ocurren en el microambiente de las neuronas 17 . Por lo general, la duración de la actividad epiléptica se correlaciona con la reducción de las funciones de la BHE, ya que el incremento en la presión arterial cerebral ocasiona que la BHE se haga permeable a macromoléculas, como albúmina, que induce alteraciones en la excitabilidad neuronal.…”
