Low GABA concentrations in occipital cortex and anterior cingulate cortex in medication-free, recovered depressed patients.
Studies using proton magnetic resonance spectroscopy (1H-MRS) indicate that unmedicated, acutely depressed patients have decreased levels of gamma-aminobutyric acid (GABA) in the occipital cortex. The aim of this study was to use 1H-MRS to determine if changes in occipital and frontal cortical GABA levels were present in patients with a history of depression who had recovered and were no longer...
متن کاملStrain, depressed mood and suicidal thoughts among maltreated adolescents in the United States.
Almost one-fourth of maltreated adolescents report they have thought about killing themselves in the last two weeks. We draw on Agnew's strain theory to develop a model to account for variability in suicidal thoughts among this high-risk group. We used data from a nationally representative sample of 572 maltreated adolescents, aged 11-15. One dimension of relational strain (poorer relationship ...
متن کاملNormal glutamate but elevated myo-inositol in anterior cingulate cortex in recovered depressed patients
BACKGROUND MRS studies of acutely depressed patients reveal decreased levels of total glutamate and glutamine (Glx) in frontal cortex which may reflect abnormalities of glutamate-glutamine cycling through astrocytes. Frontal Glx levels appear to be normalised after recovery from depression, but it is not known if this composite measure masks ongoing differences in glutamate or glutamine alone. ...
متن کاملAnterior cingulate cortex γ-aminobutyric acid in depressed adolescents: relationship to anhedonia.
CONTEXT Anhedonia, a core symptom of major depressive disorder (MDD) and highly variable among adolescents with MDD, may involve alterations in the major inhibitory amino acid neurotransmitter system of γ-aminobutyric acid (GABA). OBJECTIVE To test whether anterior cingulate cortex (ACC) GABA levels, measured by proton magnetic resonance spectroscopy, are decreased in adolescents with MDD. Th...
متن کاملBehavioral function improvement of prefrontal cortex in treated depressed rats by ECT and ketamine
Background and Objective: Depression is one of the most prevalent mental disorders. Electroconvulsive Therapy (ECT) is one of the effective methods for treatment of depression. Regarding the stimulatory effect of glutaminergic system on the progression of depression, the effect of ketamine as one of the most important inhibitors of this system has been investigated on the effectiveness of ECT. ...
