This is a serious condition in which the nervous system cells begin to die. It is called Leigh syndrome and often happens due to an inherited gene or mitochondrial change. Usually, it causes seizures, developmental delays, heart problems, and respiratory issues. While most of the time, Leigh syndrome affects children, it may also happen in […]

An autoimmune disorder that negatively affects the nerves that control muscles is called Lambert-Eaton myasthenic syndrome (LEMS). One of the most common symptoms of LEMS is muscle weakness. Moreover, most people with LEMS also have small-cell lung cancer. Doctors often prescribe cancer treatments (including chemotherapy, radiation therapy, and surgery) and other medicines to treat this […]

A rare brain disorder in which children lose their ability to speak and understand language is called Landau-Kleffner syndrome (LKS). Sometimes, it is called acquired aphasia with epilepsy by doctors. Those who develop this condition often have abnormal electrical activity in the brain and seizures. The most common treatments used in children with LKS are […]

A rare heart disease that is usually a congenital (present at birth) problem is called left ventricular non-compaction cardiomyopathy (LVNC). In people with this disorder, the lower left chamber of the heart does not develop properly, which negatively affects the heart’s ability to pump blood throughout the body efficiently. In other words, LVNC causes the […]

A health condition in which the bone marrow produces fewer blood cells (including platelets) than the body needs is called myelosuppression (also known as bone marrow suppression). This health condition significantly increases the risk of blood disorders (such as anemia), infections, and may also cause bleeding problems. Most of the time, people develop this disorder […]

A health condition that often occurs due to car crashes and falls, and causes a bruise on the heart muscle, is called a myocardial contusion (also called cardiac contusion). In other words, myocardial contusion appears when something hits the chest hard but does not go through the skin. One of the most common causes of […]

A complication of a myocardial infarction (also known as a heart attack) that occurs rarely and most of the time is fatal is called myocardial rupture. Sometimes, surgery can help an affected person survive and live many years. When surgery is not an option, doctors may perform minimally invasive surgery. Moreover, before surgery, doctors may […]

A health condition that causes inflammation of the heart muscle (myocardium) is called myocarditis. It often weakens the heart, which negatively affects its function. While it may occur due to a viral infection, some inflammatory disorders may also cause it. However, myocarditis is different from other conditions that cause inflammation because each disorder causes inflammation […]

A type of seizure that causes sharp and uncontrollable muscle movements is called myoclonic seizures. While most of the time, the symptoms are mild, sometimes, they may happen along with severe seizure disorders. Commonly, they happen in childhood, but they may also affect adults. Doctors often prescribe medicines to control the frequency and severity of […]

A chronic (long-term) disorder that negatively affects the muscles and the fascia around them is called myofascial pain syndrome. In people with this syndrome, pressing on trigger points (knots) may cause localized pain. Sometimes, this condition is mistaken for fibromyalgia, but there are different health conditions. Fascia is a connective tissue that covers the muscles, […]
