Glossary for Myokymia

  • Ataxia, episodic -- vertigo -- tinnitus -- myokymia: A rare genetic disorder characterized by episodes of incoordination and unsteadiness as well as tinnitus and vertigo. Stress, exhaustion, sudden movements and exertion may trigger the episodes. It is caused by a defect on chromosome 1q42.
  • Choreoathetosis-spasticity, episodic: A dominantly inherited movement disorder characterized by episodes of involuntary movments. Symptom episodes are often triggered by fatigue, alcohol, physical exertion and stress.
  • Cramps: The painful spasmodic muscular contraction
  • Dilantin -- Teratogenic Agent: There is strong evidence to indicate that the use of Dilantin (anti-seizure medication) during pregnancy may cause a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
  • Gamstorp-Wohlfart syndrome: A rare disorder characterized by muscle weakness, low muscle tone, increased sweating and muscle twitching (myokymia)
  • Graves Disease: is an autoimmune disease characterized by hyperthyroidism due to circulating autoantibodies. Thyroid-stimulating immunoglobulins (TSIs) bind to and activate thyrotropin receptors, causing the thyroid gland to grow and the thyroid follicles to increase synthesis of thyroid hormone.
  • Isaacs syndrome: A rare disorder where muscles suffer from stiffness and cramping, particularly limb muscles.
  • Movement disorders: Medical conditions affecting the movement systems, such as walking or tremor.
  • Multiple Sclerosis: Autoimmune attack on spinal nerves causing diverse and varying neural problems.
  • Muscle conditions: Any condition that affects the muscles of the body
  • Musculoskeletal conditions: Medical conditions affecting the musculoskeletal system of bones, muscles and related structures.
  • Nervous system conditions: Diseases affecting the nerves and the nervous system.
  • Pain: A feeling of suffering, agony, distress caused by the stimulation of pain fibres in the nervous system
  • Possible human carcinogenic exposure -- Phenytoin: Some evidence indicates that exposure to Phenytoin (an anticonvulsant medication) has a possible link to an increased risk of developing cancer in humans. The carcinogenicity of the substance may be influenced by the duration and level of exposure.
  • Stiff-Person Syndrome: A very rare progressive neurological disorder involving muscle tightness and painful muscle spasms.
  • Stiffness: Reduced mobility or movement
  • Sweating: Sweating more than normal
  • Twitches: Involuntary sudden movements of part of the body
