A new study by UC Berkeley researchers suggests that hyperreactive astrocytes are a primary driver of childhood epilepsy, particularly in the inherited disorder tuberous sclerosis complex. The findings highlight possible therapies to reduce inflammation and alleviate seizures, challenging the traditional view that neurons are the sole ...
New research from Texas A&M University suggests that younger brains may be more vulnerable to post-traumatic epilepsy after traumatic brain injury, despite their flexibility to adapt. Older brains showed fewer signs of epilepsy but were vulnerable to neuroinflammation, circuit remodeling, and memory loss.
The study found that epilepsy-associated disability-adjusted life years were concentrated in low- and lower-middle-income countries, with significant regional inequality. Progress has been made in China, including declining mortality rates, but challenges persist, particularly in rural areas where treatment gaps reach 60%–90%.
Researchers at Texas Children's Hospital have uncovered a novel biological pathway that can lead to seizures when disrupted. This finding provides a new approach for improving genetic diagnosis and treatment for epilepsy cases with unknown origins. The study also reveals that specific combinations of defective genes can cause seizures,...
Researchers at Texas A&M University have found a way to intervene early in traumatic brain injuries using a natural, gut-derived chemical that prevents post-traumatic epilepsy from taking root. The treatment reduced brain inflammation, improved memory and mood, protected brain cells, made seizures both rarer and harder to trigger.
Researchers developed mosaic mini-brains to study focal cortical dysplasia type II, a condition causing seizures in children. The findings support the two-hit model, suggesting that complete loss of DEPDC5 is necessary and sufficient to initiate the disease, with mosaicism determining lesion extent.
Researchers used base editing to correct the SCN8A gene mutation responsible for severe inherited epilepsy. The approach successfully eliminated or reduced seizures and improved brain function in lab mice, offering new hope for treating genetic epilepsies.
A mini-review synthesizes large-scale genomic findings to illuminate the polygenic architecture underlying common epilepsies. Rare genetic variants contribute to epilepsy risk, with shared biological pathways involving ion channel function and synaptic excitability
Researchers have identified two compounds that restore chloride balance in neurons, thereby allowing GABAergic signaling to regain its inhibitory function. PCPZ and CLP-257 significantly improved KCC2 efficiency, reducing seizures and other electrical markers of epileptic activity in human brain tissue and animal models.
A new advance in EEG imaging technology has improved mapping for epilepsy surgery, providing an accurate and non-invasive method. Pathological HFOs were found to be the most accurate biomarker for identifying epileptogenic brain regions, allowing for precise localization of seizure onset.
A new clinical trial is investigating the use of advanced brain monitoring to improve epilepsy diagnosis and management. The trial involves multiple sites across Europe, including Ireland, where patients will undergo long-term outpatient monitoring using a subcutaneous EEG system.
Researchers found distinct effects of single disease-causing gene variants across different brain regions, pointing to hippocampal disruptions as a key factor in cognitive problems beyond seizures. This study provides an early step toward understanding why current treatments often fall short and may help identify new therapies.
Researchers are exploring potassium channel blockers to reduce seizures caused by genetic mutations in the KCNT1 gene. The treatment holds promise for reducing life expectancy and improving symptoms, with potential clinical trials starting as early as 2026.
Researchers at Stevens Institute of Technology used ChatGPT to analyze seizure semiology descriptions and accurately localize epileptogenic zones. The results show that ChatGPT outperformed epileptologists in identifying common seizure locations but provided more accurate responses for rare regions.
A new international study has identified the P2X7 receptor as a promising target for preventing post-traumatic epilepsy. The study suggests that blocking this receptor shortly after traumatic brain injury can significantly reduce brain hyperexcitability and improve behavior.
Researchers used a radiotracer to investigate AMPAR trafficking in patients with epilepsy, finding a positive correlation between cell surface AMPAR density and gamma activity. The study suggests that Hebbian and homeostatic plasticity differentially regulate brain function in epilepsy.
A groundbreaking study found that infantile spasm patients and animal models have reduced IGF-1 levels in their brains, leading to treatment breakthroughs. The administration of an IGF-1 analog successfully eliminated spasms and abnormal brain activity in IS animal models.
Researchers at Tohoku University have discovered a stimulation paradigm that can induce epilepsy resistance in experimental animals. Repeated stimulation resulted in a dramatic decrease in seizure response to the stimulus, suggesting a potential therapeutic strategy for managing epilepsy.
