Overview
Randomized trial reveals that cerebellar inflammation and metabolism drive cognitive decline in temporal lobe epilepsy, suggesting new treatment strategies.
Key Points
- This research aims to understand how cerebellar microglial activation affects glucose metabolism and drives disease progression in temporal lobe epilepsy.
- Integrated [18F]FDG PET analysis from 55 patients and a rat model of TLE.
- Performed longitudinal [18F]FDG and [18F]DPA-714 microPET/CT imaging to assess metabolism and activation.
- Conducted mRNA sequencing and identified c-Fos as a central MAPK signaling regulator.
- Patients with TLE showed bilateral cerebellar hypermetabolism.
- Rats exhibited increased glucose uptake, Purkinje cell loss, and elevated levels of proinflammatory cytokines.
- Pharmacological intervention normalized cerebellar PET signals, reduced seizures, and improved memory performance.
