Editing Seizure (section)

==Clinical features==
Seizure manifestations vary depending on the brain regions involved and the type of seizure. They may affect [[motor skills|movement]], [[sensory system|sensation]], [[autonomic nervous system|autonomic functions]], or [[cognition|cognitive]] and emotional processing. Motor symptoms can include muscle stiffening (tonic activity), rhythmic jerking (clonic activity), sudden muscle jerks ([[myoclonus]]), or sudden loss of muscle tone ([[atonia]]). Sensory disturbances may involve tingling, visual phenomena, or [[auditory hallucination|hallucinated sounds]]. Autonomic features can include changes in heart rate, respiration, or gastrointestinal sensations. Cognitive or emotional symptoms may manifest as confusion, fear, or altered perception.

Some individuals experience an [[Aura (symptom)|aura]] before the seizure progresses, characterized by subjective sensations such as unusual smells, a sudden emotional shift, or feelings of [[déjà vu]].

Most seizures last less than two minutes and are followed by a recovery phase known as the [[postictal state]], which may include confusion, fatigue, or other neurologic symptoms.<ref name="Pottkämper2020" /> Seizures lasting more than five minutes, or occurring in rapid succession without recovery, are classified as [[status epilepticus]], a medical emergency that can result in long-term brain injury or death.<ref name="Berkowitz2022" />
