Specialty. Neurology. Paramyotonia congenita (PC) is a rare congenital autosomal dominant neuromuscular disorder characterized by "paradoxical" myotonia. [2] This type of myotonia has been termed paradoxical because it becomes worse with exercise whereas classical myotonia, as seen in myotonia congenita, is alleviated by exercise.
Periodic paralysis. Periodic paralysis is a group of rare genetic diseases that lead to weakness or paralysis [1] from common triggers such as cold, heat, high carbohydrate meals, not eating, stress or excitement and physical activity of any kind. The underlying mechanism of these diseases are malfunctions in the ion channels in skeletal muscle ...
Genetic variants. Channelopathies are a group of diseases caused by the dysfunction of ion channel subunits or their interacting proteins. These diseases can be inherited or acquired by other disorders, drugs, or toxins. Mutations in genes encoding ion channels, which impair channel function, are the most common cause of channelopathies. [ 1 ]
Hyperkalemic periodic paralysis. Hyperkalemic periodic paralysis (HYPP, HyperKPP) is an inherited autosomal dominant disorder that affects sodium channels in muscle cells and the ability to regulate potassium levels in the blood. It is characterized by muscle hyperexcitability or weakness which, exacerbated by potassium, heat or cold, can lead ...
Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder . The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles ( myotonia ) and rigidity . [ 1 ]
Myotonia is the defining symptom of many channelopathies (diseases of ion channel transport) such as myotonia congenita, paramyotonia congenita and myotonic dystrophy. [3] [4] Brody disease (a disease of ion pump transport) has symptoms similar to myotonia congenita, however, the delayed muscle relaxation is pseudo-myotonia as the EMG is normal ...
Specialty. Neurology, neuromuscular medicine. Neuromyotonia (NMT) is a form of peripheral nerve hyperexcitability that causes spontaneous muscular activity resulting from repetitive motor unit action potentials of peripheral origin. NMT along with Morvan's syndrome are the most severe types in the Peripheral Nerve Hyperexciteability spectrum.
He was the first to describe a rare neuromuscular condition known as paramyotonia congenita, a disorder sometimes referred to as "Eulenburg's disease". In 1913, along with Magnus Hirschfeld (1868–1935) and Iwan Bloch (1872–1922), he founded the Ärztliche Gesellschaft für Sexualwissenschaft und Eugenik .
