Drop attacks: an ominous change in the evolution of partial epilepsy

Area of Science:

• Neurology
• Epileptology

Background:

• Partial epilepsy is a common neurological disorder.
• Drop attacks, a severe seizure type, can significantly impact patient quality of life.

Purpose of the Study:

• To investigate the clinical characteristics and prognosis of partial epilepsy with drop attacks.
• To identify electroclinical features associated with frontal lobe epilepsy and drop attacks.

Main Methods:

• Retrospective study of 16 patients with partial epilepsy and drop attacks.
• Analysis of seizure frequency, onset, associated symptoms, EEG findings, and impact on mental health and social life.

Main Results:

• Drop attacks occurred 1-29 years after epilepsy onset, with 15 patients experiencing weekly or daily seizures despite therapy.
• Associated features included adversive seizures, atypical absences, and diffuse spike-wave discharges on EEG, suggesting frontal lobe origin.
• 6 patients developed severe mental disorders, and 13 experienced social life disruption.

Conclusions:

• Drop attacks in partial epilepsy are associated with frequent, therapy-resistant seizures.
• These seizures are linked to frontal lobe epilepsy features and portend significant morbidity, including mental disorders and social impairment.
• Drop attacks represent an ominous sign in partial epilepsy, necessitating further investigation and management strategies.
