Inter-ictal spiking
Inter-ictal spiking
Inter-ictal spiking (pronunciation: /ˌɪntərˈɪktəl ˈspaɪkɪŋ/) is a term used in neurology to describe the abnormal electrical activity in the brain that occurs between seizure episodes.
Etymology
The term is derived from the Latin inter, meaning between, and ictus, meaning a stroke or seizure. The word spiking refers to the sharp, sudden increases in electrical activity observed on an electroencephalogram (EEG).
Definition
Inter-ictal spiking is characterized by brief, intermittent bursts of high-frequency electrical activity in the brain, which are detected on an EEG. These spikes occur between seizures in individuals with epilepsy, but do not cause any noticeable symptoms or changes in behavior.
