Simple partial seizures are a type of seizure that affects only a small part of the brain. During these seizures, a person may experience unusual sensations, movements, or emotions without losing consciousness. Symptoms can include twitching of a limb, changes in vision, or strange smells. These seizures can last from a few seconds to a couple of minutes. Afterward, individuals may feel confused or tired, but they typically remember what happened. Epilepsy is a common condition associated with simple partial seizures, but they can also occur in people without this diagnosis.
