Acute Symptomatic Seizures Caused by Electrolyte Disturbances

Area of Science:

• Neurology
• Internal Medicine
• Clinical Chemistry

Background:

• Electrolyte abnormalities are common in clinical practice and can manifest as seizures.
• Seizures as a sole presenting symptom of electrolyte disturbances are under-recognized.
• Diagnosis relies on routine laboratory findings.

Purpose of the Study:

• To review the clinical relevance of electrolyte disturbances in acute symptomatic seizures.
• To highlight the diagnostic and management challenges.
• To emphasize the importance of identifying and correcting underlying electrolyte imbalances.

Main Methods:

• Narrative review of scientific literature.
• Focus on acute symptomatic seizures linked to electrolyte imbalances.
• Analysis of common electrolyte disturbances associated with seizures.

Main Results:

• Sodium disorders (hyponatremia), hypocalcemia, and hypomagnesemia are frequently associated with seizures.
• Electroencephalography (EEG) shows limited specificity for differentiating electrolyte disturbances.
• EEG findings may include background slowing or epileptiform abnormalities.

Conclusions:

• Acute symptomatic seizures due to electrolyte disturbances require prompt diagnosis and correction of the imbalance.
• Antiepileptic treatment is secondary to addressing the underlying electrolyte issue.
• Timely intervention is crucial for seizure control and preventing neurological damage.
