Background:
Reflex seizures are referred to as epileptic seizures that are consistently precipitated by a specific sensory stimulus. Reflex seizures induced by micturition are very rare, and few cases have been described.
Methods:
This study reports a case of an 11-year-old girl with seizures provoked by micturition with reference made to previously reported cases in the literature. Seizures were characterized by head and eye deviation to the right, flexed dystonic posturing of the left upper limb, extension of the right upper limb, and eventual generalized tonic-clonic seizure. Ictal electroencephalogram revealed clear electrographic evolution from the midcentral region with secondary generalization. Magnetic resonance imaging of the head was normal. Seizures were treated with a combination of lacosamide and clobazam.
Conclusions:
A midcentral ictal focus is in keeping with previous reports of this area as a potential epileptogenic center for micturition-induced seizures.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Seizures: Classification
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:

Epilepsy and Seizures: Overview
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
