A recent study delved into the cognitive differences found in people with Juvenile Myoclonic Epilepsy (JME), a specific type of epilepsy that often appears in adolescence. The researchers wanted to see how these cognitive profiles compared to those of unaffected siblings and unrelated controls. To do this, they gathered a group of 77 JME participants, 19 unaffected siblings, and 44 unrelated controls, all between the ages of 12 and 25, and gave them a series of neuropsychological tests.

Cholesterol is more than just a thing we hear about in relation to heart health; it plays a crucial role in our brain’s functioning too. When there’s an imbalance in how cholesterol is produced and processed in the brain, it can lead to serious issues, including conditions like epilepsy. Since cholesterol can’t simply pass through the blood-brain barrier, our brains have to make their own cholesterol, with a special enzyme called cholesterol 24-hydroxylase (CH24H) taking the lead in this process.

In a fascinating study on drug-resistant focal epilepsy, researchers set out to better understand the brain’s electrical activity during seizures. This particularly involves what happens when the brain shifts from a calm state (interictal) to an active seizure state (ictal). By analyzing stereo-electroencephalographic (SEEG) signals from ten patients, they sought to identify patterns in the activity of the epileptogenic zone network (EZN), which includes various interconnected brain regions that contribute to seizure initiation.

A recent study has shed light on the relationship between seizures and neurodevelopmental outcomes in young children with tuberous sclerosis complex (TSC), a genetic condition that often leads to epilepsy and intellectual disabilities. Researchers tracked 129 TSC patients from birth to three years old, analyzing their seizure patterns, brain scans, and developmental milestones. They aimed to determine how the timing of seizures and the overall number of seizures affected cognitive development.

Researchers are exploring a new way to diagnose epilepsy using ultra-low-field (ULF) magnetic resonance imaging (MRI), which could be a game-changer, especially in areas where traditional high-field MRI is hard to access due to cost and technology limitations. While high-field MRI is the gold standard for diagnosing epilepsy, not everyone can get one promptly—even in wealthier countries.

In a fascinating exploration of electrical brain activity, researchers investigated how the brain’s electrical patterns, measured through EEG (electroencephalography), differ in patients with STXBP1 developmental and epileptic encephalopathy (STXBP1-DEE). Monogenic epilepsies, like STXBP1-DEE, are caused by mutations in a single gene, yet there’s been limited focus on how these patients’ EEGs vary from others.

Researchers have recently uncovered fascinating insights into a gene called SLC35A2, which is linked to a rare condition that affects brain development and can cause epilepsy, known as mild malformations of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE). While SLC35A2 mutations have been flagged as genetic markers for this condition, how this gene influences brain development and contributes to seizure activity has remained a bit of a mystery.

A recent study from the University Medical Center Utrecht explored the genetic underpinnings of epilepsy in patients with suspected malformations of cortical development (MCD) who underwent surgery between 2015 and 2020. By combining their findings with data from four other studies, the researchers focused on identifying pathogenic genetic variants in brain tissue samples from 663 patients. Shockingly, they discovered that about 31% of these cases had a pathogenic variant, which can influence how epilepsy develops and responds to treatment.
