Myasthenia gravis Myasthenia gravis is a rare long-term condition that causes certain muscles to become weak. It mainly affects muscles that are controlled voluntarily – often those controlling eye and eyelid movement, facial expression, chewing, swallowing and speaking.
Muscular dystrophy The muscular dystrophies (MD) are a group of inherited genetic conditions that gradually cause the muscles to weaken, leading to an increasing level of disability.
Lambert-Eaton myasthenic syndrome Lambert-Eaton myasthenic syndrome (LEMS) is a rare disorder caused by a problem with the transmission of nerve signals to the muscles. It results in muscle weakness and sometimes dryness of the mouth, constipation and impotence.
Hypotonia Hypotonia is the medical term for decreased muscle tone. Healthy muscles are never fully relaxed. They retain a certain amount of tension and stiffness (muscle tone) that can be felt as resistance to movement.
Fibromyalgia Fibromyalgia, also called fibromyalgia syndrome (FMS), is a long-term condition that causes pain all over the body. As well as widespread pain, people with fibromyalgia may also have: increased sensitivity to pain fatigue (extreme tiredness)
Dystonia Dystonia is a medical term for a range of movement disorders that cause muscle spasms and contractions. The spasms and contractions may either be sustained or may come and go.
Dupuytren's contracture Dupuytren’s contracture (Dupuytren's disease) is a condition that affects the hands and fingers. It causes one or more fingers to bend into the palm of the hand. It can affect one or both hands, and sometimes affect the thumb.
Myositis (polymyositis and dermatomyositis) Myositis is a general term that means "inflammation of the muscles". The symptoms are muscle weakness, tripping or falling, and fatigue (tiredness) after walking or standing. It can feel like permanently having the flu.
Cholinesterase Tests Cholinesterases are enzymes that are involved in helping the nervous system to function properly. There are two separate cholinesterase enzymes in the body: (1) acetylcholinesterase, found in red blood cells as well as in the lungs, spleen, nerve endings, and the gray matter of the brain, and (2) pseudocholinesterase (butyrylcholinesterase), found in the serum as well as the liver, muscle, pancreas, heart, and white matter of the brain. Cholinesterase tests measure the activity of these enzymes.
What is Congenital Myasthenia? All forms of myasthenia are due to problems in the communication between nerve cells and muscles. Most involve the activities of neurotransmitters. Neurotransmitters are chemicals that allow neurons to relay information from one cell to the next.
