Subcortical epilepsy?

AI Article Synopsis

  • The cortex has traditionally been seen as the main source of seizures in epilepsy, but recent studies show that seizures involve interactions between both cortical and subcortical structures.
  • Various types of epileptic discharges engage different subcortical structures in distinctive ways, indicating a more complex network involvement.
  • This review aims to explore evidence that some subcortical structures may independently initiate seizures and discuss the clinical impact of this finding.

Article Abstract

In the past, the cortex has for the most part been considered to be the site of seizure origin in the different forms of epilepsy. Findings from histopathologic, electrophysiologic, and brain imaging studies now provide ample evidence demonstrating that like normal cerebral function, epileptic seizures involve widespread network interactions between cortical and subcortical structures. These studies show that different forms of generalized and focal epileptiform discharges and seizures engage various subcortical structures in varying ways. This interaction has been the subject of many reviews and is not the focus of the current work. The aim of this review is to examine the evidence suggesting the possibility for some of the subcortical structures to initiate seizures independently and the clinical implications of this.

Accurately predicting individual antidepressant treatment response could expedite the lengthy trial-and-error process of finding an effective treatment for major depressive disorder (MDD). We tested and compared machine learning-based methods that predict individual-level pharmacotherapeutic treatment response using cortical morphometry from multisite longitudinal cohorts. We conducted an international analysis of pooled data from six sites of the ENIGMA-MDD consortium (n = 262 MDD patients; age = 36.

Comparison and calibration of MP2RAGE quantitative T1 values to multi-TI inversion recovery T1 values.

Magn Reson Imaging

While typical qualitative T1-weighted magnetic resonance images reflect scanner and protocol differences, quantitative T1 mapping aims to measure T1 independent of these effects. Changes in T1 in the brain reflect structural changes in brain tissue. Magnetization-prepared two rapid acquisition gradient echo (MP2RAGE) is an acquisition protocol that allows for efficient T1 mapping with a much lower scan time per slab compared to multi-TI inversion recovery (IR) protocols.

The applause sign (AS) is a recognized phenomenon observed in progressive supranuclear palsy (PSP) and other neurological conditions where individuals produce over three claps following a request to clap only thrice after a demonstration. In this study, we introduced a novel linguistic phenomenon termed the oral applause sign (OAS) associated with the AS. The OAS is characterized by increased repetition counts of Japanese repetitive onomatopoeic words, such as uttering "pata-pata-pata" instead of the expected "pata-pata.

Background: The presence of frailty is common in people with Parkinson's disease, as is cognitive dysfunction. Previous research on frailty has focused on the physical aspects of the pathology.

Aims: To analyze the relationship between frailty and cognitive impairment in patients with Parkinson's disease and to know which disease characteristics are associated with frailty.
