Moyamoya disease is a rare and complex condition that affects the blood vessels in the brain. It is characterized by the blockage or narrowing of the carotid artery, which reduces blood flow to the brain.

Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacterial infection that has become resistant to many antibiotics. MRSA is caused by a type of staph bacteria that is resistant to the antibiotic methicillin and other semisynthetic penicillins. MRSA infections can occur in people who have been in hospitals or other health care settings, as well as in people who have not been in these settings.
Multiple endocrine neoplasia type 1 (MEN 1) is a rare genetic disorder that affects the endocrine glands and small intestine. Also known as Wermer's syndrome, MEN 1 is a complex condition that causes tumors to grow in the endocrine glands and parts of the small intestine and stomach. The excess hormones released by these tumors can lead to a wide range of signs and symptoms.
Multiple endocrine neoplasia type 2 (MEN 2) is a rare genetic disorder that affects the thyroid and parathyroid glands, adrenal glands, lips, mouth, eyes, and digestive tract. The condition is characterized by the growth of benign tumors in these areas, which can lead to a range of symptoms and complications.
Multiple system atrophy (MSA) is a rare neurological disorder that affects the brain's ability to control movement, balance, and other bodily functions. It is characterized by the degeneration of several systems in the body, including the autonomic nervous system, cerebellum, and brainstem.

There are many kinds of muscular dystrophy, and symptoms can vary depending on the type and severity of the condition.
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex disorder that causes extreme fatigue that lasts for at least six months. Symptoms worsen with physical or mental activity but do not fully improve with rest. The cause of ME/CFS is unknown, although there are many theories. Experts believe it might be triggered by a combination of factors.
Myelodysplastic syndromes (MDS) are a group of disorders characterized by the production of abnormal blood cells that do not function properly. MDS is caused by something amiss in the spongy material inside your bones where blood cells are made (bone marrow). The disorder can lead to anemia, fatigue, and infections.
Myelofibrosis is a rare and complex type of bone marrow cancer that disrupts the normal production of blood cells. It is characterized by the replacement of normal bone marrow with fibrous tissue, leading to severe anemia and other complications. Myelofibrosis is a chronic disease that can significantly impact quality of life.
Myocarditis is an inflammatory condition that affects the heart muscle, known as the myocardium. The condition can reduce the heart's ability to pump blood effectively, leading to a range of symptoms and complications. Myocarditis can be caused by various factors, including viral infections, medication reactions, and autoimmune disorders.
