Premature ovarian insufficiency (POI), by definition, occurs when a woman has her last menstrual period before the age of 40, because of variable, and most often permanent ovarian dysfunction. It presents as hypergonadotropic hypogonadism with peripheral amenorrhea. It has a prevalence of 1-2%, but in women under 20 years its prevalence is one case in every 10,000 women. POI is a devastating diagnosis for women of reproductive age. Many conditions can lead to POI, but it is most commonly idiopathic, and it has a variable clinical presentation. It has serious health consequences, including psychological disorders such as anxiety or depression, infertility, osteoporosis, autoimmune disorders, cardiovascular diseases, and an increased risk of mortality.

Common Types of Seizures in Adolescents and Adults
The clinical diagnosis of an epileptic seizure requires a detailed history taking and, ideally, an eyewitness account of the seizure. Evaluation with 12-lead electrocardiography is essential in a patient who has had a first seizure or an unexplained blackout spell.
Patients who have had an epileptic seizure should be informed about factors that may provoke seizures (e.g., sleep deprivation and alcohol use), the risk of a seizure occurring while driving or engaging in solitary activities, and the risks of harm from further seizures.
