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

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...

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...

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...

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

Anti-glutamic acid decarboxylase limbic encephalitis without epilepsy evolving into dementia with cerebellar ataxia.

OBJECTIVES To expand the spectrum of the clinical presentation of anti-glutamic acid decarboxylase antibodies-related limbic encephalitis and to improve the recognition of this entity. DESIGN Case study. SETTING University hospital. PATIENT An 11-year-old-girl with progressive mood and behavioral disorder, speech impairment, and short-term memory impairment who manifested cerebellar ataxi...
