Objective: On the occasion of the First Congress of the Spanish Anti Epilepsy League we had reviewed the use of antiepileptic drugs for preventing postoperative and posttraumatic seizures.
Development: Two specific causes of epilepsy are particularly relevant to neurosurgical practice; postoperative and posttraumatic epilepsy. After reviewing the seizures arising after craniotomy for supratentorial conditions such as vascular malformations (aneurysms and arteriovenous malformations), cerebral tumours and supratentorial abscesses and empyemas, we discuss the different types of posttraumatic epilepsy and the risk factors. The pathogenesis of tumour associated epilepsy and the pathophysiological events initiating posttraumatic epilepsy are described. The use of prophylactic antiepileptic drugs is only justified in cases with several risk factors capable to develop seizures.
Conclusion: As no treatments have yet been shown to be effective in preventing the development of epileptic seizures, additional trials are likely to be necessary.

Traumatic brain injury is a significant risk factor for the development of post-traumatic epilepsy (PTE), posing a major clinical challenge. This review discusses the critical role of GABAergic interneurons and reactive astrogliosis in the pathophysiology of post-traumatic epilepsy, integrating findings from our research group within the traumatic brain injury context with recent literature to highlight the impact of excitation-inhibition imbalance. We analyzed alterations in interneuron populations, specifically subtypes expressing the calcium-binding proteins parvalbumin, calretinin, and calbindin, and their association with an increased risk of epileptogenesis after TBI.

Post-traumatic epilepsy (PTE) is a debilitating chronic outcome of traumatic brain injury (TBI). Although FTO has been reported as a possible intervention target of TBI, its precise roles in the PTE remain incompletely understood. Here we used mild or serious mice TBI model to probe the role and molecular mechanism of FTO in PTE.

The gut-brain axis plays an integral role in maintaining overall health, with growing evidence suggesting its impact on the development of various neuropsychiatric disorders, including depression. This review explores the complex relationship between gut microbiota and glutamate (Glu) regulation, highlighting its effect on brain health, particularly in the context of depression following certain neurological insults. We discuss how microbial populations can either facilitate or limit Glu uptake, influencing its bioavailability and predisposing to neuroinflammation and neurotoxicity.

: Chronobiology has gained attention in the context of paediatric neurological and neuropsychiatric disorders, including migraine, epilepsy, autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and post-traumatic stress disorder (PTSD). Disruptions in circadian rhythms are associated with key symptoms such as sleep disturbances, mood dysregulation, and cognitive impairments, suggesting a potential for chronobiology-based therapeutic approaches. : This narrative review employs a systematic approach to identify relevant studies through searches of three major scientific databases, NCBI/PubMed, ScienceDirect, and Scopus, up to July 2024.

Traumatic brain injury (TBI) and subsequent post-traumatic epilepsy (PTE) often impair daily activities and mental health (MH), which contribute to long-term TBI-related disability. PTE also affects driving capacity, which impacts functional independence, community participation, and satisfaction with life (SWL). However, studies evaluating the collective impact of PTE on multidimensional outcomes are lacking.
