Area of Science:

• Neuroscience
• Epileptology
• Pharmacology

Background:

• Seizure clusters, or acute repetitive seizures, involve recurrent seizures with brief recovery periods.
• These events can impair GABAergic inhibition in the brain, leading to neuronal hyperactivation.
• Pathological mechanisms include altered GABA_A receptor function and dysregulated chloride homeostasis.

Purpose of the Study:

• To review the pathophysiology of seizure clusters.
• To identify clinical challenges in diagnosing and treating seizure clusters.
• To highlight strategies for improving patient care and quality of life.

Main Methods:

• Literature review of seizure cluster pathophysiology and treatment.
• Analysis of clinical definitions and treatment gaps.
• Discussion of patient and caregiver experiences.

Main Results:

• Seizure clusters involve GABAergic inhibition breakdown and CA1 pyramidal neuron hyperexcitability.
• Clinical practice faces challenges due to variable definitions and lack of consensus on treatment.
• Patient and caregiver quality of life is significantly impacted by unpredictability and anxiety.

Conclusions:

• Targeted therapies, like benzodiazepines, are crucial but face access barriers.
• Improved patient and clinician education on seizure cluster recognition and management is essential.
• Personalized seizure action plans and appropriate rescue medication use can improve outcomes and reduce patient burden.
