Developmental and/or epileptic encephalopathy with spike-wave activation in sleep
MONDO:0800501A rare epileptic encephalopathy of childhood characterized by seizures, an electroencephalographic (EEG) pattern of electrical status epilepticus in sleep (ESES) and neurocognitive regression in at least 2 domains of development. This syndrome encompasses the previous syndromes epileptic encephalopathy with continuous spike-wave in sleep and atypical childhood epilepsy with centrotemporal spikes (also previously known as pseudo-Lennox syndrome and atypical benign partial epilepsy).
Also known as: CSWS, CSWSS syndrome, DEE-SWAS, EE-SWAS, EESWAS, ESES with language regression, LK syndrome, LKS

New hope for kids with rare sleep epilepsy?
Disease control CompletedThis study tested a drug called NBI-827104 in 24 children with a rare epilepsy that causes constant brain spikes during sleep. The drug is a calcium channel blocker given daily for 13 weeks. The main goal was to see if it reduces abnormal brain activity measured by EEG.
Phase: PHASE2 • Sponsor: Neurocrine Biosciences • Aim: Disease control

Could a magnetic helmet calm Seizure-Like brain waves in sleeping children?
Symptom relief CompletedThis study tested a wearable device that uses magnetic pulses to stimulate the brain in 10 children with a rare epilepsy called CSWS, where abnormal brain activity occurs during sleep. The device was applied for just 10 minutes to the area causing the seizures. Researchers measur…
