The thalamocortical network appears to play a pivotal role in ictogenesis. We herein present three cases of non-convulsive status epilepticus (SE), in adult patients without previous history of epilepsy or seizures, precipitated by acute thalamic vascular and metabolic-induced lesions. In all cases the EEG showed patterns consistent with generalized SE confirmed either by a fast and complete clinical and EEG response to anti-seizure medication or definitive subtle motor signs consistent with SE. We argue that the subcortical disruption of thalamocortical networks due to the thalamic lesion predisposed to the occurrence of non-convulsive SE. In patients with thalamic disorders and unexplained mental status changes EEG evaluation should always be considered.

The patient was a 69-year-old right-handed woman. She had sensory aphasia, and the brain MRI revealed a subacute phase hemorrhage in the left subcortical temporal lobe. We speculated that the patient had post-ictal aphasia due to symptomatic epileptic seizures associated with cerebral hemorrhage.

Refractory and Super-Refractory Status Epilepticus: Therapeutic Options and Prognosis.

Neurol Clin

February 2025

Department of Neurology, University of Lausanne, Lausanne, Switzerland. Electronic address:

In patients with status epilepticus (SE), the underlying biologic background represents the main prognostic variable. A swift application of a treatment protocol is recommended, including adequate doses of a benzodiazepine followed by an intravenous anti-seizure medicine. If refractory SE arises, general anesthetics should be used in generalized convulsive and non-convulsive SE in coma, while further non-sedating anti-seizure medications attempts are warranted in patients with focal forms.

Utility of CT perfusion in seizures and rhythmic and periodic patterns.

Clin Neurophysiol

December 2024

Department of Neurology, Johns Hopkins Bayview Medical Center, Baltimore, MD 21224, USA; Epilepsy Center, Department of Neurology, The Johns Hopkins Hospital, Baltimore, MD 21287, USA. Electronic address:

Objective: CT hyper-perfusion has been reported in non-convulsive status epilepticus (NCSE), while its occurrence and relevance after single seizures or with rhythmic and periodic patterns (RPPs) that lie along the ictal-interictal continuum (IIC), remain unclear. The goal of the study is to assess the role of CT perfusion (CTP) in diagnosing patients with clinical seizures, subclinical seizures, or RPPs that lie along the IIC, to help in the clinical assessment of these entities.

Methods: We retrospectively reviewed inpatients who underwent a CTP and an EEG within 6 h of each other.
