Dyscontrol syndrome: long-term follow-up.

Area of Science:

• Neuroscience
• Clinical Psychiatry
• Epileptology

Background:

• Episodic behaviors are often suspected to originate from limbic complex partial seizures.
• Patients with intermittent explosive disorder, panic disorder, or epilepsy variants may benefit from anticonvulsant therapy.

Purpose of the Study:

• To evaluate the efficacy of anticonvulsant regimens in patients with suspected limbic complex partial seizures causing episodic behaviors.
• To assess the diagnostic utility of drug-activated electroencephalograms (EEG) and clinical assessment in guiding treatment selection.

Main Methods:

• A 38- to 57-month follow-up of 50 patients referred for drug-activated EEG.
• Inclusion criteria: suspicion of limbic complex partial seizures, normal routine EEGs, and primary diagnoses of intermittent explosive disorder, panic disorder, or epilepsy variants.
• Treatment recommendations based on EEG findings, dyscontrol behavior checklist, and episodic disorder history; subsequent medication management tracked.

Main Results:

• Anticonvulsant regimens were recommended for 39 patients, initiated in 25.
• Of 20 patients on seizure threshold-raising regimens, 10 reported marked improvement and six reported moderate improvement.
• Diagnostic procedures and treatment response analysis did not yield reliable data for regimen selection.

Conclusions:

• While specific diagnostic predictors were not identified, regimens that raise seizure threshold demonstrated potential benefit for patients with episodic behaviors linked to suspected limbic seizures.
• Further research is needed to refine diagnostic and therapeutic strategies for this patient population.
