Abstract
Disorders of reproduction are unusually common among people with epilepsy. They are generally associated with and may be the consequence of reproductive endocrine disorders. Epilepsy itself and epileptic seizures have been implicated in their pathophysiology.
This review focuses on how temporolimbic dysfunction in epilepsy might disrupt normal neuroendocrine regulation and promote the development of reproductive endocrine disorders. The particular nature of the dysregulation may relate to the laterality and focality of the epilepsy and some hormonal changes may develop in close temporal relation to the occurrence of epileptiform discharges. In women, reproductive endocrine disorders include polycystic ovary syndrome, hypothalamic amenorrhea, functional hyperprolactinemia, and premature menopause. In men, hypogonadism may be hypogonadotropic, hypergonadotropic or related to hyperprolactinemia. The significance of these reproductive endocrine disorders is that they may contribute not only to sexual dysfunction and infertility, but may also have an adverse impact on seizure control.
This review also includes sections on special considerations in the treatment of reproductive endocrine disorders for women and men with epilepsy.
Zusammenfassung
Reproduktionsstörungen sind unter Menschen mit Epilepsie ungewöhnlich weit verbreitet. Sie sind allgemein mit reproduktiven endokrinen Störungen verbunden und können auch deren Resultat sein. In ihrer Pathophysiologie spielen die Epilepsie selbst sowie epileptische Anfälle eine Rolle.
Dieser Überblick befasst sich mit der Frage, wie temporolimbische Dysfunktion bei Epilepsie die normale neuroendokrine Regulation stören und die Entwicklung von reproduktiven endokrinen Störungen fördern kann. Die besondere Natur der Dysregulation mag mit der Lateralität und Fokalität der Epilepsie zusammenhängen und manche hormonelle Veränderungen können sich im engen zeitlichen Zusammenhang zum Auftreten von epileptiformen Entladungen entwickeln. Bei Frauen umfassen reproduktive endokrine Störungen das polyzystische Ovar-Syndrom, die hypothalamische Amenorrhoe, die funktionelle Hyperprolaktinämie und die vorzeitige Menopause. Bei Männern kann der Hypogonadismus hypogonadotrop, hypergonadotrop oder durch Hyperprolaktinämie verursacht sein. Die Bedeutung dieser reproduktiven Erkrankungen ist, dass sie nicht nur zu sexueller Dysfunktion und Unfruchtbarkeit führen, sondern auch ungünstige Auswirkungen auf die Anfallsbehandlung haben können.
Der Überblick enthält auch Abschnitte zu speziellen Überlegungen in der Behandlung von reproduktiven endokrinen Störungen bei Frauen und Männern mit Epilepsie.
