Neurological disorders associated with glutamic acid decarboxylase antibodies: a Brazilian series

Association of Paraneoplastic Neurological Disorders With Glutamic Acid Decarboxylase Antibodies.

Neurological disorders associated with glutamic acid decarboxylase antibodies: a Brazilian series Distúrbios neurológicos associadas a anticorpos anti-GAD (descarboxilase do ácido glutâmico): uma série de casos brasileira

Neurological disorders associated with glutamic acid decarboxylase (GAD) antibodies include stiff-person syndrome (SPS) and its variants — stiff trunk syndrome, stiff limbs syndrome, progressive encephalomyelitis with rigidity, SPS-plus and paraneoplastic SPS — as well as epilepsy and ataxia1-8. These syndromes are often found in association with other autoimmune disorders, such as diabetes mel...

Antibodies against glutamic acid decarboxylase: prevalence in neurological diseases.

UNLABELLED High prevalence of autoantibodies against glutamic acid decarboxylase (GAD-Ab) in stiff man syndrome (SMS) not only helps diagnosis, but also suggests immune mediated impairment of GABAergic functions. However, the presence of GAD-Ab has also been reported in other neurological syndromes. Therefore the prevalence of GAD-Ab was investigated in SMS, progressive encephalomyelitis with r...

Antibodies to Inhibitory Synaptic Proteins in Neurological Syndromes Associated with Glutamic Acid Decarboxylase Autoimmunity

Antibodies to glutamic acid decarboxylase (GAD-ab) associate to different neurological syndromes. It is unknown if the diversity in syndrome association represents epitopes in different immunodominant domains or co-existence of antibodies to other proteins of the inhibitory synapsis. We examined the serum and CSF of 106 patients with anti-GAD related syndromes (39 cerebellar ataxia, 32 stiff-pe...

Spectrum of neurological syndromes associated with glutamic acid decarboxylase antibodies: diagnostic clues for this association.

The association of high levels of autoantibodies to glutamic acid decarboxylase (GAD-ab) and stiff-person syndrome (SPS) is well known. However, the full spectrum of neurological syndromes associated with GAD-ab is not well established. In addition, these patients usually present type 1 diabetes mellitus (DM1) that could justify the presence of high GAD-ab levels. To clarify these issues, we re...
