ORIGINAL CONTRIBUTION Brain -Aminobutyric Acid Changes in Stiff-Person Syndrome
نویسندگان
چکیده
Background: Patients with stiff-person syndrome (SPS) have circulating antibodies against glutamic acid decarboxylase, the rate-limiting enzyme responsible for the synthesis of -aminobutyric acid (GABA). Although the patients’ symptoms of stiffness and unexpected spasms can be explained on the basis of reduced or impaired inhibitory neurotransmitters, such as GABA, it is unclear whether the level of GABA in the brains of these patients is reduced and, if so, whether the reduction is due to anti–glutamic acid decarboxylase antibodies.

Stiff person case misdiagnosed as conversion disorder: A case report
Background: Stiff person syndrome (SPS) is a rare neurological disease resulting in stiffness and spasm of muscles. It initially affects the axial muscles and then spread to limb muscles. Emotional stress exacerbated the symptoms and signs of the disease. The pathophysiology of the disease is caused by the decreased level of the glutamic acid decarboxylase (GAD) activity due to an autoantibody ...
متن کاملNIH CONFERENCE The Stiff-Person Syndrome: An Autoimmune Disorder Affecting Neurotransmission of g-Aminobutyric Acid
The stiff-person syndrome, a rare and disabling disorder, is characterized by muscle rigidity and episodic spasms that involve axial and limb musculature. Continuous contraction of agonist and antagonist muscles caused by involuntary motor-unit firing at rest are the hallmark clinical and electrophysiologic signs of the disease. Except for global muscle stiffness, results of neurologic examinat...
متن کاملStiff Person Syndrome.
Stiff-person syndrome or Moersch-Woltmann is a very rare and disabling neurologic disorder characterized by muscle rigidity and episodic spasms involving axial and limb musculature. It is an autoimmune disorder resulting in a malfunction of aminobutyric acid mediated inhibitory networks in the central nervous system. We describe a patient of stiff person syndrome.
متن کاملAnti-glutamic acid decarboxylase antibody positive neurological syndromes
A rare kind of antibody, known as anti-glutamic acid decarboxylase (GAD) autoantibody, is found in some patients. The antibody works against the GAD enzyme, which is essential in the formation of gamma aminobutyric acid (GABA), an inhibitory neurotransmitter found in the brain. Patients found with this antibody present with motor and cognitive problems due to low levels or lack of GABA, because...
متن کاملNovel use of dual immunomodulation for treating stiff-person syndrome, cerebellar variant.
Stiff-person syndrome is an autoimmune syndrome defined by muscle spasms and rigidity of proximal and axial muscles. Glutamic acid decarboxylase is the autoantigen found in 60%–80% of stiff person syndrome patients. Stiff person syndrome, cerebellar variant was characterized in a subpopulation of patients (5 of 38) with stiff person syndrome and concomitant cerebellar dysfunction and confirmed ...
