Frequency and Pathophysiology of Post-Seizure Todd's Paralysis.

Frequency and Pathophysiology of Post-Seizure Todd's Paralysis. Med Sci Monit. 2020 Mar 05;26:e920751 Authors: Xu SY, Li ZX, Wu XW, Li L, Li CX Abstract Todd's paralysis, a neurological abnormality characterized by temporary limb weakness or hemiplegia, typically occurs following a seizure, without enduring consequences. Since limb weakness or hemiplegia can also be a common symptom of an acute ischemic stroke, it is often difficult to diagnose Todd's paralysis in individuals experiencing an acute ischemic stroke if they do not have a pre-existing history of epilepsy. Given that there is a limited understanding of Todd's paralysis, this review discusses the history, prevalence, clinical manifestations, duration, etiology, and diagnosis of Todd's paralysis. A few factors that may help clinicians distinguish Todd's paralysis from other clinical indications are as follows: (1) Todd's paralysis is commonly observed after partial seizures or generalized tonic-clonic seizures. (2) The incidence of Todd's paralysis is greater if the epilepsy is associated with old age or stroke history. (3) The duration of Todd's paralysis can range from minutes to days, depending on the type of seizure or whether the patient has experienced cortical structural damage. (4) The etiology of Todd's paralysis is associated with cerebral perfusion abnormality after seizures. Further research is needed to explore factors that distinguish Todd's paralysis from other indications that ma...

Abstract AIM OF THE STUDY: The aim of the study was to evaluate the clinical characteristics of patients with previous stroke (either ischemic or hemorrhagic), who developed status epilepticus (SE) mimicking a stroke relapse. MATERIALS AND METHODS: We performed a retrospective cohort study of patients brought to hospital by the emergency service between December 2016 and January 2018 with a stroke code as possible candidates for intravenous thrombolysis and who had already have a previous stroke. Among them, patients admitted for negative symptoms and finally discharged with a diagnosis of SE mimicking stroke...

Purpose of review Imaging constitutes one of the key pillars in the diagnostic workup after a first seizure as well as for the presurgical workup in epilepsy. The role of imaging in emergency situations, mainly to support the adequate diagnosis, as well as its role in planning of noninvasive image-guided therapies is less well established. Here, we provide an overview on peri-ictal imaging findings to support differential diagnosis in emergency situations and describe recent attempts toward minimal invasive therapy in the treatment of epilepsy and its comorbidities based on a combination of imaging techniques with ultras...

ConclusionIn patients with acute epileptic seizures, regional hyperperfusion on PCT may suggest an ongoing or recently resolved SE, whereas hypoperfusion may be due to post-ictal state or simultaneous AIS. These observations might help attributing focal deficits to epileptic seizures rather than stroke, allowing for targeted therapy.

Bindoff Stroke-like lesions are characteristically associated with mitochondrial encephalopathies such as those caused by mutations of polymerase gamma (POLG) and the m.3243A>G mitochondrial DNA (mtDNA) mutation. The combination of acute clinical onset, MRI and pathological abnormalities, have led to the suggestion that these lesions are ischemic. Here, we sought to determine the role of ischemia in the pathogenesis of mitochondrial stroke-like lesions. We performed a sys...
