Epilepsy is a long-term, fairly common brain condition that manifests as sudden surges of electricity in the brain. These electrical bursts cause people to experience seizures. Different types of epilepsy lead to different types of seizures, which can impact the brain in various ways.
For example, generalized epilepsy results in generalized seizures. Not all generalized seizures are motor (that is, involving physical movements). That said, sudden muscle twitches, spasms, and other erratic movements can accompany generalized seizures. Non-motor generalized seizures, on the other hand, feature little movement beyond minor twitches and fluttering eyelids.
By comparison, people living with focal epilepsy experience focal seizures, which begin as a slightly nauseous feeling in the stomach. As symptoms progress, they can take the form of motor and non-motor seizures, though the seizures differ from those observed in people living with generalized epilepsy. Focal motor seizures sometimes consist of repeated movements, such as chewing or clapping, while symptoms of focal non-motor seizures range from waves of heat and cold throughout the body to a sudden change in emotions and thoughts.
Other individuals may live with combined generalized and focal epilepsy, or even unknown forms of epilepsy. Unsurprisingly, the latter can result in symptoms known as unknown seizures.
