Also called “ictal SPECT”, this procedure can detect areas of the brain with changes in cell metabolism, blood flow, or transmissions between brain cells during a seizure. These areas of altered activity can indicate seizure-causing conditions in a particular patient.

The ictal examination is crucial for neuroanatomic localization of seizure onset, which informs medical and neurosurgical treatment of epilepsy. Substantial variation exists in ictal examination performance in epilepsy monitoring units (EMUs).

Ictal-postictal semiology helps determine lateralisation and localisation. Possible psychogenic nonepileptic attack disorder may require tailored testing. Ictal and postictal testing carried out in long-term epilepsy monitoring units is often sub-optimal.

SPECT is a nuclear medicine test to detect changes in blood flow in your child’s brain; it can help doctors pinpoint the area deep within your child’s brain that is causing his or her epileptic seizures.

Single-photon emission computed tomography (SPECT) is a nuclear radiology study that measures the blood flow in the brain. A safe, short-lived radioactive substance is injected into the arm and a CT (computed tomography) scan is performed shortly afterwards.

Ictal single photon emission computed tomography (SPECT) can be used as an advanced diagnostic modality to detect the seizure onset zone in the presurgical evaluation of people with epilepsy.

Nov 1, 2024 · The test creates a detailed 3D map of the blood flow in the brain that happens during a seizure. A healthcare professional also may do a type of SPECT test called subtraction ictal SPECT coregistered with MRI (SISCOM).

EEG correlates of high risk for seizures are categorized as ictal (during a seizure), postictal (after seizure) or interictal (between seizures). These distinctions often are unclear and arbitrary, in that the interictal-ictal boundaries are blurred for many seizures. Even so …

Jul 21, 2016 · We present the standardized ictal testing battery (ITB) developed by the European taskforce, and evaluation of its feasibility, during implementation in clinical practice in 10 participating centers.

Results: The proposed standardised assessment battery provides a comprehensive and user-friendly format for ictal-postictal testing, and examines consciousness, language, motor, sensory, and visual function.
