Our understanding of the mechanisms of loss and recovery of consciousness, following severe brain injury or during anesthesia, is changing rapidly. Recent neuroimaging studies have shown that patients with chronic disorders of consciousness and subjects undergoing general anesthesia present a complex dysfunctionality in the architecture of brain connectivity. ⋯ Despite ongoing efforts, the mechanisms underlying the emergence of consciousness after severe brain injury are not thoroughly understood. Important questions remain unanswered: What triggers the connectivity impairment leading to disorders of consciousness? Why do some patients recover from coma, while others with apparently similar brain injuries do not? Understanding these mechanisms could lead to a better comprehension of brain function and, hopefully, lead to new therapeutic strategies in this challenging patient population.

Report of a parent survey of cannabidiol-enriched cannabis use in pediatric treatment-resistant epilepsy.
Severe childhood epilepsies are characterized by frequent seizures, neurodevelopmental delays, and impaired quality of life. In these treatment-resistant epilepsies, families often seek alternative treatments. This survey explored the use of cannabidiol-enriched cannabis in children with treatment-resistant epilepsy. ⋯ Because of the increasing number of states that allow access to medical cannabis, its use will likely be a growing concern for the epilepsy community. Safety and tolerability data for cannabidiol-enriched cannabis use among children are not available. Objective measurements of a standardized preparation of pure cannabidiol are needed to determine whether it is safe, well tolerated, and efficacious at controlling seizures in this pediatric population with difficult-to-treat seizures.

Validation of the Greek version of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E).
The Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) was developed as a screening tool for symptoms of major depressive episodes in people with epilepsy. Our study describes the development, validation, and psychometric properties of the Greek version of the NDDI-E. A consecutive sample of 101 patients with epilepsy, eligible to participate in the study, has been assessed using the Mini International Neuropsychiatric Interview version 5.0.0 and the NDDI-E. ⋯ Cronbach's alpha coefficient was 0.74. Receiver operating characteristic analysis showed an area under the curve of 91% (95% CI=83%-99%; SE: 0.040, p<0.001). At a cutoff score of greater than 15, the NDDI-E showed a sensitivity of 91%, a specificity of 81%, and a negative predictive value of 97%.

Mesial temporal lobe epilepsy with no specific histological abnormality: a distinct surgically remediable syndrome.
The purposes of the study were twofold: to clarify the clinical features and surgical outcome of mesial temporal lobe epilepsy (MTLE) with no specific histological abnormality and to determine the optimal surgical strategy. ⋯ Mesial temporal lobe epilepsy with no specific histological abnormality is a clinical entity distinctly different from MTLE with HS. Bitemporal independent and/or nonlateralizing seizure onset on intracranial EEG is very common. Although the presence of lateral temporal and/or extratemporal epileptogenicity should always be kept in mind, postoperative seizure outcome after AHE is favorable even in cases with bitemporal independent and/or nonlateralizing seizure onset.
