Convulsive syncope on electroencephalogram

Convulsive syncope: a condition to be differentiated from epilepsy.

The clinical presentation of epilepsy and syncope can be confusingly similar. We present a patient with reflex syncopal episodes that mimic seizures using video-EEG recordings. During the episodes, head/eye deviations, automatisms and dystonic movements, suggesting an epileptic seizure, were observed. The EEG revealed diffuse slow waves when the patient lost consciousness and complete cessation...

The relation between the electroencephalogram and muscle action potentials in certain convulsive states.

STUDY in man of the relation between the occurrences in the electroencephalogram (EEG) and the muscular jerkings in convulsive states has been limited. Possibly this has been due to the difficulty of anticipating the time of onset of seizures sufficiently often, and with sufficient accuracy. In two types of case this difficulty may be overcome. The first is that in which myoclonic jerkings occu...

Clinical risk factors for non-convulsive status epilepticus during emergent electroencephalogram

PURPOSE Emergent electroencephalograms (EmEEG) are performed to exclude non-convulsive status epilepticus (NCSE) but are resource-intensive. Prior studies have identified a seizure or seizures in the acute setting preceding the EmEEG request as a risk factor of NCSE but few other consistent clinical risk factors have been identified. We aimed to identify clinical risk factors for NCSE in EmEEGs...

Convulsive syncope induced by the Valsalva maneuver in subjects exhibiting low G tolerance.

Convulsive syncope related to a small dose of quetiapine in an adolescent with bipolar disorder

Quetiapine, an atypical antipsychotic, has been extensively used in patients with bipolar disorder. Overdose of quetiapine can result in severe complications, such as coma, seizure, respiratory depression, arrhythmia, and even death. However, the paucity of toxicological evaluation in adolescence causes more potential risks in this population. Herein, we present a case of hypotension and convul...
