Todd's paralysis (remaining temporary partial paralysis or weakness of a limb)

Introduction Todd: Under normal circumstances, patients with epilepsy have no significant changes in limb function after seizures, but some patients with partial seizures have no motility after seizures, and they return to normal after several minutes to several hours. We call this temporary sputum after seizures Todd, also known as Todd palsy. When Todd occurs in patients with epilepsy, it often prompts patients with organic lesions in the brain, and must be further examined to determine the cause.

Cause

The cause is not yet clear, but there are two assumptions. One is the theory of loss, that is, the depletion of the motor cortex leads to the prolongation of hyperpolarization of neurons. The second is the transient motor fiber inactivation caused by NMDA receptor activation. Since sputum will disappear quickly, the treatment of the disease is symptomatic and supportive. The prognosis of the disease is related to the extent of epilepsy.

Todd's paralysis is an abnormality of the nervous system that occurs in patients with epilepsy, that is, a transient paralysis that occurs in epileptic seizures. The tendon can be local or whole body, but usually only occurs on one side of the body. It is most common after a full-body tonic-clonic attack (large episode) and may last for several hours or occasionally for a few days after the epileptic seizure.

Differential diagnosis

The most significant significance of the disease is the differential diagnosis of stroke. In the acute phase, certain strokes can trigger localized seizures. And if Todd occurs in such a context, the patient's nervous system is often overestimated, leading to medical measures such as thrombolytic therapy errors. For this reason, thrombolytic therapy is generally considered a relative contraindication to seizures in the acute phase of stroke, especially in the absence of evidence of cerebrovascular infarction before angiographic imaging. . Thrombolytic therapy is contraindicated in cases where there is no clear diagnosis. It is recommended to use anti-epilepsy, anticoagulation, vasodilation, nutrient brain cells, free radical scavenging, acupuncture and other measures, and further examination as soon as possible, for example, diffusion-weighted imaging (DWI) in CT and MRI The diagnosis of cerebral ischemic stroke has important value.
