Summary
Piloerection, a rare seizure symptom, is often linked to temporal lobe epilepsy. This case documents pilomotor seizures in a patient with left temporal lobe epilepsy, offering insights into seizure localization.
Area of Science:
- Neurology
- Epileptology
- Clinical Neuroscience
Background:
- Piloerection is an uncommon ictal manifestation frequently associated with temporal lobe epilepsy.
- Understanding the semiology of rare seizure types is crucial for accurate diagnosis and localization.
Observation:
- This study presents video and electrographic evidence of pilomotor seizures in a 75-year-old male patient.
- The patient had a history of left temporal lobe epilepsy and remote herpes zoster encephalitis.
Findings:
- Piloerection is typically localized to the temporal lobe.
- Unilateral piloerection often correlates with ipsilateral seizure onset.
- Bilateral piloerection's lateralizing value is less certain, but left hemispheric predominance is suggested.
Implications:
- This case contributes to the understanding of pilomotor seizures and their association with temporal lobe epilepsy.
- Detailed documentation aids in recognizing and localizing seizures based on piloerection.
- Further research may clarify the lateralizing significance of bilateral piloerection in epilepsy.

01:13Seizures: Classification
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

01:19Seizures ll: Types
Seizures are sudden bursts of abnormal electrical discharge in the brain that interfere with normal function. They are commonly divided into three groups: focal seizures, generalized seizures, and other types that do not fit neatly into either category.Focal SeizuresFocal seizures begin in a single brain region. When awareness is preserved, they are called focal aware seizures and may cause sensations such as tingling, unusual smells, or flashing lights. When awareness is impaired, they are...
01:20Seizures l: Introduction
Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...
01:24Epilepsy and Seizures: Overview
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

01:22Epilepsy ll: Types
Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.
