What is NDM?
NDM is a group of rare conditions that affects one’s muscles. Only around 1 in 100,000 people worldwide suffer from these conditions, but there are countries where NDM is more common.1 There are several different forms of NDM, with 4 main types commonly known as Becker Myotonia Congenita, Thomsen Myotonia Congenita, Paramyotonia Congenita (Eulenburg) or Hyperkalemic periodic paralysis (hyperPP).1,2
NDM disorders typically affect the muscles, with patients most commonly having an inability to relax muscles immediately after they have been used, which is called myotonia.1 Patients experience myotonia symptoms differently, describing their experience as stiffness, cramps or “locking” of their muscles during everyday tasks and movements.3 In addition to patients experiencing their symptoms differently, patients often describe their symptoms as unpredictable as they may differ from time to time4,5 and they may range from subtle effects on muscles that have little impact on the ability to move to more severe symptoms that significantly affect daily activities.1,3
Struggling to open your hand after clenching your fist may be a sign that you have NDM.6
