tailieunhanh - STEROIDS – CLINICAL ASPECT

Epilepsy has a gender-related pathophysiology and consequences. Therefore, being a woman with epilepsy is not the same as being a man with epilepsy (Taubøll et al, 2008); in fact, the frequency and severity of seizures can increase on certain days of the menstrual cycle (Herzog et al, 1997). Seizures generally exacerbate during the 3 different periods of the menstrual cycle: in perimenstrual and periovulatory periods in normal cycles, and in inadequate luteal phase in abnormal cycles (Figure 1). This type of epilepsy is defined as catamenial epilepsy and is under the influence of estrogen and progesterone. Estrogen has been shown to increase seizure activity, while progesterone decreases. | STEROIDS -CLINICAL ASPECT Edited by Hassan Abduljabbar Steroids - Clinical Aspect Edited by Hassan Abduljabbar Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
