What are Centrotemporal spikes?
Centrotemporal spikes refers to the part of the brain where the focal seizures associated with this syndrome occur, which controls movement. ‘Benign’ refers to the fact that children usually develop normally and that seizures usually cease spontaneously by puberty.
What causes BECTS epilepsy?
The EEG pattern that is seen in BECTS is inherited in an autosomal dominant pattern. Several different possible gene mutations seem to cause this pattern. Only about a quarter of children who inherit this EEG pattern have seizures, so it seems likely that other genes or environmental factors also influence BECTS.
What does a Rolandic seizure look like?
Benign rolandic epilepsy is characterized by twitching, numbness or tingling of the child’s face or tongue, and may interfere with speech and cause drooling. Seizures spread from one area of the brain and become generalized.
What is ictal Piloerection?
Ictal piloerection (goose bumps) is a rare, frequently overlooked, clinical symptom during seizures. It was first described in 18961 and its prevalence was estimated at 1.2% in a group of 420 patients with pharmaco-resistant temporal lobe epilepsy.
What does it mean when EEG shows spikes?
Spikes or sharp waves are terms commonly seen in EEG reports. If these happen only once in a while or at certain times of day, they may not mean anything. If they happen frequently or are found in specific areas of the brain, it could mean there is potentially an area of seizure activity nearby.
What is a Pilomotor seizure?
Pilomotor seizure1,2 is a rare subtype of autonomic epilepsy related to temporal lesion of which it may be the presenting symptom, usually associated with other manifestations of temporal lobe epilepsy. Figure Brain MRI.
What causes piloerection?
The scientific term for hair standing on end is piloerection. It’s a reflex that causes tiny muscles near our hair follicles to contract and raise the hairs. This can be caused by a number of stimuli — for example, a cool breeze on a warm day.
What triggers a myoclonic seizure?
A myoclonic seizure happens when your muscles suddenly contract, causing quick twitching movements. It usually affects one side of the body and involves the neck, shoulders, and upper arms.
Is a Persyst spike a seizure?
The presence of spikes and sharp waves in EEG data strongly support a diagnosis of epilepsy or an elevated risk of seizures. Their morphologic characteristics and spatial distribution are key aspects for either localizing potential foci of seizure origin or in establishing a syndromic diagnosis.
