Fatal uncoupling in the epileptic brain
Epilepsy is a very prevalent neurological disorder. Approximately one-third of patients are resistant to currently available therapies. A team of researchers has discovered a new cause to explain the development of temporal lobe epilepsy: At an early stage, astrocytes are uncoupled from each other. This results in the extracellular accumulation of potassium ions and neurotransmitters, which cause hyperexcitability of the neurons, researchers say.
