Pharmacoresistant epilepsy is a disabling neuronal disorder with harmful consequences that impact patient's quality of life. Although psychiatric comorbidities are frequently present in patients with epilepsy, they are more common in those patients with pharmacoresistant epilepsy. Despite medical advances, the current existing therapeutic strategies for pharmacoresistant seizure control are not available for all patients and/or present disadvantages. Moreover, the conventional drug therapies for psychiatric comorbidities have several adverse effects. Therefore, in this field, nanotechnology arises as a novel tool for transporting drugs to the brain under pathological conditions with high efficiency and low side effects. </p> <p> Objective: Present an overview of nanotechnology as a novel, efficient and enhanced therapeutic strategy for controlling pharmacoresistant epilepsy and its associated psychiatric comorbidities. </p> <p> Conclusion: Nanotechnology emerges as a powerful tool for the control and/or treatment of pharmacoresistant epilepsy and its comorbidities in a more efficient and safer way than conventional treatments.

Objective: Hypothalamic hamartomas (HHs) are associated with pharmacoresistant epilepsy. Stereotactic radiofrequency thermocoagulation (SRT) shows promise as a disconnecting intervention. Although magnetic resonance imaging (MRI) is typically used to determine the attachment and intervention side, it presents challenges in cases of bilaterally attached HH, where the epileptogenic side is unclear.

Excitation-inhibition (E/I) imbalance is theorized as a key mechanism in the pathophysiology of epilepsy, with ample research focusing on elucidating its cellular manifestations. However, few studies investigate E/I imbalance at the macroscale, whole-brain level, and its microcircuit-level mechanisms and clinical significance remain incompletely understood. Here, the Hurst exponent, an index of the E/I ratio, is computed from resting-state fMRI time series, and microcircuit parameters are simulated using biophysical models.

Among the most prevalent are hemophilia A (deficiency of Factor VIII), hemophilia B (deficiency of Factor IX), and von Willebrand disease. Management of pharmacoresistant epilepsy is more difficult in a patient with bleeding disorder due to increased risk of bleeding during surgery.

Purpose: Analysis of autofluorescence holds promise for brain tumor delineation and diagnosis. Therefore, we investigated the potential of a commercial confocal laser scanning endomicroscopy (CLE) system for clinical imaging of brain tumors.
Methods: A clinical CLE system with fiber probe and 488 nm laser excitation was used to acquire images of tissue autofluorescence.

Epilepsy affects more than 70 million individuals of all ages worldwide and remains one of the most severe chronic noncommunicable neurological diseases globally. Several neurotransmitters, membrane protein channels, receptors, enzymes, and, more recently noted, various pathways, such as inflammatory and mTORC complexes, play significant roles in the initiation and propagation of seizures. Over the past two decades, significant developments have been made in the diagnosis and treatment of epilepsy.
