motor seizure

motor seizure

abnormal electrical activity that arises initially in a localized motor area of the cerebral cortex. The manifestations depend on the site of the abnormal electrical activity, such as tonic contractures of the thumb caused by excessive discharges in the motor area of the cortex controlling the first digit or chewing movements resulting from discharges in the lower part of the motor strip controlling mastication. The disturbance may spread, resulting in generalized convulsion, or it may end in a shower of clonic movements. See also epilepsy, focal seizure.

The duration of the motor seizure was recorded as the time from the ECT stimulus to the cessation of tonic-clonic motor activity in the 'isolated' arm; the duration was assessed by an observer through a window outside of the operating theatre to blind the observer to the anaesthetic agent used.

Motor seizure is a temporary disturbance in brain function caused by abnormal nerve signals that begin in a local motor nerve area of the brain.
Motor seizure duration, electroencephalogram (EEG) seizure duration, and postictal suppression index (PSI) were recorded from the EEG and electromyography traces obtained during the seizure.
The unmodified motor seizure was also monitored using an isolated forearm technique.
Motor seizure duration was recorded as the time interval between ECT stimulus and cessation of tonic-clonic motor activity in the isolated upper limb, while EEG seizure duration was recorded as the interval between ECT stimulus and post-ictal EEG suppression.

For instance, in a patient with parieto-occipital epilepsy, either being due to a cortical development abnormality or an infarct, while the seizure presentation may only be the generalized motor seizures, depending upon the spread of seizure activity, visual aura, automotor seizure, focal clonic seizure, or bilateral asymmetrical tonic seizures may well appear individually or in cluster.
After a mean 847 days of follow-up, the researchers observed a responder rate of 32% in patients with complex partial seizures, 63% in patients with generalized tonic-clonic seizures, and 26% in those with total, disabling seizures (simple partial motor seizures, complex partial seizures, and generalized tonic-clonic seizures combined).

Focal seizures invariably involve one side of the body and are most commonly motor seizures.
Comment: In 98 people with Lennox-Gastaut syndrome, aged 1-30 years, adjunctive use of Topamax reduced the number of drop attacks and major motor seizures.
