The postictal state is the altered state of consciousness after an epileptic seizure. It usually lasts between 5 and 30 minutes, but sometimes longer in the case of larger or more severe seizures, and is characterized by drowsiness , confusion , nausea , hypertension , headache or migraine , and other disorienting symptoms.
Postictal phase; The postictal phase causes are multifactorial to include alteration of cerebral blood flow and effects on multiple neurotransmitters. [10] These changes after a generalized tonic–clonic seizure cause a period of postictal sleep with stertorous breathing. Confusion and total amnesia upon regaining consciousness are also ...
After the active portion of a seizure (the ictal state) there is typically a period of recovery during which there is confusion, referred to as the postictal period, before a normal level of consciousness returns. [28] It usually lasts 3 to 15 minutes [48] but may last for hours. [49]
A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizures).
This causes disturbed messages to be sent to other parts of the brain, in turn causing the symptoms of a seizure and can include changes in behavior, consciousness, movements, or feelings. The disorder of electrical signals causes excessive excitation or loss of inhibition, which is a function of malfunctioning ion channels, as ...
Thereafter, the seizure may or may not evolve into loss of consciousness and a generalized tonic–clonic seizure. [2] [1] In contrast to the auras in ecstatic seizures, most auras of seizures generally are unpleasant, including feelings of anxiety and fear (60%) as well as depression, while positive feelings are only rarely reported.

Todd's paresis (or postictal paresis/paralysis, "after seizure") is focal weakness in a part or all of the body after a seizure. This weakness typically affects the limbs and is localized to either the left or right side of the body. It usually subsides completely within 48 hours. Todd's paresis may also affect speech, eye position (gaze), or ...
In the remainder (42%), consciousness becomes impaired during the ictal progress, and in one-third, there is no recollection of ictal events. Progression to hemiconvulsions or generalized tonic-clonic seizures occurs in around half of children and hemiconvulsions may be followed by postictal Todd's hemiparesis.
