AI Article Synopsis

  • Piloerection can occur during seizures in temporal lobe epilepsy, which is uncommon.
  • A 38-year-old man experienced repetitive pilomotor seizures without typical symptoms, delaying his epilepsy diagnosis by a month.
  • Diagnostic imaging showed changes in specific brain areas, and while treatment led to seizure freedom, follow-up MRI indicated ongoing brain changes a year later, highlighting the connection between piloerection and the mesial temporal region.

Article Abstract

Piloerection is a rare ictal manifestation of temporal lobe epilepsy. The case is a 38-year-old man with acute onset of repetitive pilomotor seizures. Lacking other symptoms implicating epileptic seizures, a month passed before he was diagnosed with epilepsy. Ictal electroencephalography revealed rhythmic waves in the right temporal area. Reversible magnetic resonance imaging (MRI) abnormalities were visible in the right hippocampus, right uncus, and right amygdala. The appropriate antiepileptic drug therapy made him seizure-free, but following MRI, he showed right hippocampal atrophy one year after seizure cessation. This case is significant in that we can follow sequential MRI from onset, and it is meaningful for considering the mesial temporal area as involved with piloerection.

Acetazolamide as an effective treatment for pilomotor seizures in autoimmune encephalitis.

Epilepsia

May 2024

Division of Neurology, Department of Medicine, Krembil Brain Institute, University Health Network, University of Toronto, Toronto, Canada.

Pilomotor seizures are strongly associated with autoimmune encephalitis (AE), particularly anti-LGI1 encephalitis. The carbonic anhydrase inhibitor acetazolamide may have special efficacy for treating AE-associated pilomotor seizures. Six patients with AE (five anti-LGI1, one seronegative) and temporal lobe pilomotor seizures (five with seizures inducible by hyperventilation) were treated with acetazolamide, administered in a cycling (2-days-ON, 4-days-OFF) regimen to offset tolerance.

Focal seizures, characterized by excessive electrical excitation in a brain region, present diagnostic challenges due to diverse manifestations, particularly with non-motor symptoms. Here, we present a 69-year-old Japanese woman experiencing unexplained recurrent episodes of sweating, chills, and shivering. Despite exhaustive investigations that identified no abnormalities, her symptoms remained unalleviated by symptomatic treatments.

Paraneoplastic Neurologic Syndromes.

Continuum (Minneap Minn)

December 2023

Objective: Progress is ongoing in understanding paraneoplastic neurologic disorders, with new syndromes and antibodies being described and more detailed evidence available to guide workup for diagnosis and treatment to improve outcomes. Many excellent reviews have summarized the molecular features of different antibodies, but this article emphasizes the clinical features of each syndrome that may help guide initial diagnosis and treatment, which often should occur before an antibody or cancer is found to confirm the diagnosis.

Latest Developments: Recent findings include updated diagnostic criteria with validated sensitivity and specificity, discovery of novel antibodies, and clinical findings that increase the likelihood of an underlying paraneoplastic disorder.

Metabolic phenotyping of pilomotor seizures in autoimmune encephalitis.

CNS Neurosci Ther

September 2023

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Objectives: Ictal piloerection (IP) is an uncommon symptom in focal epilepsy and is associated with autoimmune encephalitis (AE). However, the networks involved in AE-associated IP are still unclear. To have a better understanding of IP underlying mechanisms, the current study investigated whole-brain metabolic networks for the analysis of AE-associated IP.
