Acute Cerebellar Ataxia Associated with Anti-glutamic Acid Decarboxylase Antibodies Mimicking Miller Fisher Syndrome

Acute Cerebellar Ataxia Associated with Anti-glutamic Acid Decarboxylase Antibodies Mimicking Miller Fisher Syndrome

We herein report the case of a 53-year-old man with cerebellar ataxia with anti-glutamic acid decarboxylase antibody (GAD-Ab) who mimicked Miller Fisher syndrome (MFS). He developed ophthalmoplegia, diplopia, and gait ataxia for one week. The serum and cerebrospinal fluid GAD-Ab titers were greatly increased, and the GAD-Ab index suggesting intrathecal antibody synthesis was elevated, while GQ1...

Experience with immunotherapy in 3 patients with cerebellar ataxia associated with anti-glutamic acid decarboxylase antibodies.

La asociación con niveles altos de anticuerpos contra la enzima carboxilasa del ácido glutámico (anti-GAD) es bien conocida en el síndrome de la persona rígida o Stiff person syndrome (SPS) y, más recientemente, también se han descrito en un subgrupo de pacientes con ataxia cerebelosa1,2. Sobre la base del probable origen autoinmune de estos síndromes se han ensayado distintas terapias inmunomo...

Epilepsy and cerebellar ataxia associated with anti-glutamic acid decarboxylase antibodies.

Anti-glutamic acid decarboxylase (GAD) antibodies are described in stiff-person syndrome and also in other neurological syndromes, including cerebellar ataxia and epilepsy. This paper reports the case of a patient who had chronic focal epilepsy, upbeat nystagmus and cerebellar ataxia, associated with a polyautoimmune response including anti-GAD antibodies. Both gait and nystagmus improved marke...

Cerebellar ataxia associated with anti-glutamic acid decarboxylase (anti-GAD) autoantibodies: a rare and puzzling disease.

Cerebellar ataxia associated to anti-glutamic acid decarboxylase autoantibody (anti-GAD): partial improvement with intravenous immunoglobulin therapy.

CASE A 51 year-old man presented to our hospital with nine-years history of progressive gait instability, difficulty walking and insulin dependent diabetes. Family history was unremarkable. On examination, there was ataxic gait, severe limb and trunk ataxia, and dysarthria. He scored 65 in International Cooperative Ataxia Rating Scale (ICARS) and 20 in Scale for Assessment and Rating of Ataxia ...
