Lance-Adams syndrome (LAS) is a rare neurological disorder that may occur after cardiopulmonary resuscitation. The LAS is usually caused by hypoxic changes. Neuroimaging studies show that the brain pathology of LAS patients is not uniform, and the pathophysiology of the myoclonus can vary from patient to patient. Our case study contributes to this etiological heterogeneity by neuroimaging and transcranial magnetic stimulation (TMS). In patients with rare brain conditions such as LAS, a combination of brain stimulation methods, such as TMS, and diffusion tensor imaging can provide insights into this condition's pathophysiology. These insights can facilitate the development of more effective therapies.

Myoclonus After Cardiac Arrest: Need for Standardization-A Systematic Review and Research Proposal on Terminology.

Objectives: Although myoclonus less than or equal to 72 hours after cardiac arrest (CA) is often viewed as a single entity, there is considerable heterogeneity in its clinical and electrophysiology characteristics, and its strength of association with outcome. We reviewed definitions, electroencephalogram, and outcome of myoclonus post-CA to assess the need for consensus and the potential role of electroencephalogram for further research.

Lance Adams syndrome (LAS) is characterized by chronic action or intention myoclonus resulting from cerebral hypoxia. Perampanel, a non-competitive antagonist of aamino-3-hydroxy-5methyl-4 isooxazoleproprionic acid glutamate receptor, has demonstrated some efficacy in myoclonic epilepsy and other types of myoclonus. We report significant benefit in a patient with LAS treated with add on perampanel and provide a review of the relevant literature.

Article Synopsis
- A study reports a new type of negative myoclonus observed in three patients with acute post-anoxic brain injury (PABI).
- The researchers analyzed EEG and muscle recordings, revealing a pattern of whole body tonic posturing accompanied by brief periods of muscle relaxation in two out of the three patients.
- The findings suggest that this phenomenon can be identified using sEMG and may involve cortical or reticular brain regions, contributing to our understanding of brain recovery after oxygen deprivation.

Background And Objectives: Lance-Adams syndrome (LAS), or chronic posthypoxic myoclonus, is a long-term disabling neurologic disorder occurring in survivors of anoxia. The cortical or subcortical origin of this myoclonus is unclear. We aimed to identify the neuroanatomical origin of myoclonus in LAS.
