Title

Choline rise in the rat hippocampus induced by electroconvulsive shock treatment

Overall design

The aim of this study was to test whether electroconvulsive treatment (ECT) unspecifically induces an increase of magnetic resonance spectroscopy (MRS)-detectable choline concentration in the rat hippocampus. Rats received a 6-day course of daily electroconvulsive shock (ECS) treatment and were observed with MRS. Animals underwent a first MRS scan (pre-ECS) at day 1. During the following 6 days, animals were treated with ECS (administered once daily on days 2-7). A second MRS scan (post-ECS) was obtained at day 8. Rat hippocampi (n = 28) were investigated via magnetic resonance spectroscopy and signal intensities of choline (Cho), total creatine (tCr), and N-acetyl aspartate (NAA) were measured and expressed as ratios. Metabolite quantification was reported relative to total creatine or N-acetyl aspartate as the reference peak.
