Study reports seizure-freedom in 68 percent of juvenile myoclonic epilepsy patients
A 25-year follow-up study reveals that 68% of patients with juvenile myoclonic epilepsy (JME) became seizure-free, with nearly 30% no longer needing antiepileptic drug (AED) treatment. Findings published today in Epilepsia, a journal of the International League Against Epilepsy (ILAE), report that the occurrence of generalized tonic-clonic seizures preceded by bilateral myoclonic seizures, and AED polytherapy significantly predicted poor long-term seizure outcome.
Scientists uncover deja vu mystery
In a groundbreaking study, researchers from the Czech Republic and the United Kingdom have discovered a link between the déjà vu phenomenon and structures in the human brain, effectively confirming the neurological origin of this phenomenon. Despite past studies investigating this phenomenon in healthy individuals, no concrete evidence had ever emerged … until now. The study is presented in the journal Cortex.
Persistent sensory experience is good for aging brain
Despite a long-held scientific belief that much of the wiring of the brain is fixed by the time of adolescence, a new study shows that changes in sensory experience can cause massive rewiring of the brain, even as one ages. In addition, the study found that this rewiring involves fibers that supply the primary input to the cerebral cortex, the part of the brain that is responsible for sensory perception, motor control and cognition. These findings promise to open new avenues of research on brain remodeling and aging.
Genetic ‘reset switch’ enables signaling pathway to induce multiple developmental outcomes for olfactory neurons
Within the nervous system, a handful of signaling pathways modulate development of a cornucopia of different neuronal subtypes. Even small alterations in neuron differentiation pathways can disrupt subsequent circuit organization and catalyze the genesis of neurological disorders, explains Adrian Moore of the RIKEN Brain Science Institute in Wako.
