A multidisciplinary team led by researchers from the Spanish Research Council (CSIC) identifies the genomic cellular map associated with hippocampal sclerosis, a major histopathological condition of temporal lobe epilepsy. The study, published in Cell Reports, identifies cell-type specific transcriptional signatures of hyper-excitability and neurodegeneration, providing grounds for improved diagnosis. While the presence of sclerosis is essential for identifying temporal lobe epilepsy (the most common form of drug-resistant epilepsy), it is also detected in some cases of dementia associated with Alzheimer’s disease.
