Summaries for Stiff-Person Syndrome

OMIM : 58 The stiff-person syndrome (SPS) is most often an adult-onset sporadic acquired disorder characterized by progressive muscle stiffness with superimposed painful muscle spasms accompanied by electromyographic evidence of continuous motor activity at rest. SPS has been associated with autoimmune disorders, diabetes mellitus, thyrotoxicosis, and hypopituitarism with adrenal insufficiency (George et al., 1984). Approximately 60% of patients with SPS have antibodies to glutamic acid decarboxylase (GAD2, or GAD65; 138275), the rate-limiting enzyme in the synthesis of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), suggesting an immune-mediated pathogenesis (Folli et al., 1993). Approximately 10% of patients develop SPS as a paraneoplastic neurologic disorder associated with antibodies to amphiphysin (AMPH; 600418), an intracellular protein associated with neuronal synaptic vesicle endocytosis (Burns, 2005). See also congenital stiff-man syndrome, or hereditary hyperexplexia (149400), which is caused by mutations in subunits of the glycine receptor gene (GLRA1, 138491; GLRB, 138492). Meinck and Thompson (2002) provided a detailed review of stiff-person syndrome. They also discussed 2 possibly related conditions, progressive encephalomyelitis with rigidity (PERM), a more severe disorder with other neurologic features, and stiff-limb or stiff-leg syndrome, a focal disorder.

MalaCards based summary : Stiff-Person Syndrome, also known as stiff-man syndrome, is related to hyperekplexia and limbic encephalitis, and has symptoms including fever, opisthotonus and increased sweating. An important gene associated with Stiff-Person Syndrome is GAD2 (Glutamate Decarboxylase 2), and among its related pathways/superpathways are Neuroscience and Glucose / Energy Metabolism. The drugs Glycine and Antibodies have been mentioned in the context of this disorder. Affiliated tissues include thyroid, brain and bone, and related phenotypes are hyperhidrosis and emg abnormality

Disease Ontology : 12 A movement disease that is of unknown etiology characterized by progressive rigidity.

NIH Rare Diseases : 54 Stiff person syndrome (SPS) is a rare, progressive syndrome that affects the nervous system, specifically the brain and spinal cord. Symptoms may include extreme muscle stiffness, rigidity and painful spasms in the trunk and limbs, severely impairing mobility. Spasms can generate enough force to fracture bone. People with SPS often have heightened sensitivity to noise, sudden movements, and emotional distress, which can set off muscle spasms. Persistent symptoms can lead to abnormal posturing of the spine, such as being hunched over. The syndrome affects twice as many women as men. SPS is caused by increased muscle activity due to decreased inhibition of the central nervous system. It is thought to have an autoimmune component and is often associated with diabetes, as well as other autoimmune diseases such as thyroiditis, vitiligo, and pernicious anemia. It may be diagnosed after having various tests including blood tests (including a test showing elevated glutamic acid decarboxylase (GAD) antibodies), a lumbar puncture, and electromyography. Treatment aims to control symptoms and improve mobility, and may involve benzodiazepines, muscle relaxants, and/or intravenous immunoglobulin (IVIG). While some people with SPS may maintain reasonable levels of activity with treatment, the majority become disabled over time.

NINDS : 55 Stiff-person syndrome (SPS) is a rare neurological disorder with features of an autoimmune disease.  SPS is characterized by fluctuating muscle rigidity in the trunk and limbs and a heightened sensitivity to stimuli such as noise, touch, and emotional distress, which can set off muscle spasms.  Abnormal postures, often hunched over and stiffened, are characteristic of the disorder.  People with SPS can be too disabled to walk or move, or they are afraid to leave the house because street noises, such as the sound of a horn, can trigger spasms and falls.  SPS affects twice as many women as men.   It is frequently associated with other autoimmune diseases such as diabetes, thyroiditis, vitiligo, and pernicious anemia.  Scientists don’t yet understand what causes SPS, but research indicates that it is the result of an autoimmune response gone awry in the brain and spinal cord.  The disorder is often misdiagnosed as Parkinson’s disease, multiple sclerosis, fibromyalgia, psychosomatic illness, or anxiety and phobia.  A definitive diagnosis can be made with a blood test that measures the level of glutamic acid decarboxylase (GAD) antibodies in the blood.  People with SPS have elevated levels of GAD, an antibody that works against an enzyme involved in the synthesis of an important neurotransmitter in the brain.
