Arteriosclerosis Arteriosclerosis occurs when the blood vessels that carry oxygen and nutrients from your heart to the rest of your body (arteries) become thick and stiff — sometimes restricting blood flow to your organs and tissues. Healthy arteries are flexible and elastic, but over time, the walls in your arteries can harden, a condition commonly called hardening of the arteries. Atherosclerosis is a specific type of arteriosclerosis, but the terms are sometimes used interchangeably. Atherosclerosis refers to the build-up of fats, cholesterol and other substances in and on your artery walls (plaque), which can restrict blood flow. The plaque can burst, triggering a blood clot. Although atherosclerosis is often considered a heart problem, it can affect arteries anywhere in your body. Atherosclerosis may be preventable and is treatable. Causes Atherosclerosis is a slow, progressive disease that may begin as early as childhood. Although the exact cause is unknown, atherosclerosis ma...

Seizures and Epilepsy in Children Epilepsy is a brain condition that causes a child to have seizures. It is one of the most common disorders of the nervous system. It affects children and adults of all races and ethnic backgrounds. The brain consists of nerve cells that communicate with each other through electrical activity. A seizure occurs when one or more parts of the brain has a burst of abnormal electrical signals that interrupt normal brain signals. Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure. This includes a high fever, high or low blood sugar, alcohol or drug withdrawal, or a brain concussion. But when a child has 2 or more seizures with no known cause, this is diagnosed as epilepsy. There are different types of seizures. The type of seizure depends on which part and how much of the brain is affected and what happens during the seizure. The 2 main categories of epileptic seizures are focal (partial) seizure and general...

Sheehans's Syndrome Sheehan's Syndrome, also known as Postpartum Hypopituitarism or Postpartum Pituitary Necrosis, is a condition in which hypopituitarism develops after severe bleeding ('Postpartum hemorrhage') during or immediately after childbirth . The incidence of Sheehan's syndrome has decreased with better health care during childbirth and delivery but is still about 0.5% of all cases of hypopituitarism in women. Blood loss generally has to be more than 800ml for Sheehan's Syndrome to develop. But in certain women, even minimal bleeding seems to cause this condition. Cause of Sheehan's Syndrome Sheehan's syndrome occurs due to necrosis of the anterior lobe of the pituitary gland. This part of the gland secretes important hormones like the ACTH, TSH, FSH, LH, growth hormones, endorphins and prolactin. During normal pregnancy, the anterior pituitary lobe increases greatly in size since it is required to secrete larger amounts of these hormones,...

Antisocial personality disorder, sometimes called sociopathy, is a mental disorder in which a person consistently shows no regard for right and wrong and ignores the rights and feelings of others.
