The precise etiology of ASD is still unknown and probably heterogeneous. In a subgroup of patients, toxic environmental exposure might lead to an imbalance between oxidative stress and anti-oxidant systems. Previous serum and postmortem studies measuring levels of glutathione (GSH), the main cellular free radical scavenger in the brain, have supported the hypothesis that this compound might play a role in the pathophysiology of autism. METHODS: Using the method of single-voxel proton magnetic resonance spectroscopy (MRS), we analyzed the GSH signal in the dorsal anterior cingulate cortex (dACC) and the dorsolateral prefrontal cortex (DLPFC) of 24 ASD patients with normal or above average IQs and 18 matched control subjects. We hypothesized that we would find decreased GSH concentrations in both regions. RESULTS: We did not find overall group differences in neurometabolites including GSH, neither in the dorsal ACC (Wilks' lambda test; p = 0.429) nor in the DLPFC (p = 0.288). In the dACC, we found a trend for decreased GSH signals in ASD patients (p = 0.076). CONCLUSIONS: We were unable to confirm our working hypothesis regarding decreased GSH concentrations in the ASD group. Further studies combining MRS, serum, and cerebrospinal fluid measurements of GSH metabolism including other regions of interest or even whole brain spectroscopy are needed.

Index. décimale : PER Périodiques Résumé : INTRODUCTION: Autism spectrum disorder (ASD) encompasses a heterogeneous group with varied phenotypes and etiologies. Identifying pathogenic subgroups could facilitate targeted treatments. One promising avenue is investigating energy metabolism, as mitochondrial dysfunction has been implicated in a subgroup of ASD. Lactate, an indicator of energy metabolic anomalies, may serve as a potential biomarker for this subgroup. This study aimed to examine cerebral lactate (Lac+) levels in high-functioning adults with ASD, hypothesizing elevated mean Lac+ concentrations in contrast to neurotypical controls (NTCs). MATERIALS AND METHODS: Magnetic resonance spectroscopy (MRS) was used to study cerebral Lac+ in 71 adults with ASD and NTC, focusing on the posterior cingulate cortex (PCC). After quality control, 64 ASD and 58 NTC participants remained. Lac+ levels two standard deviations above the mean of the control group were considered elevated. RESULTS: Mean PCC Lac+ levels were significantly higher in the ASD group than in the NTC group (p=0.028; Cohen's d=0.404), and 9.4% of the ASD group had elevated levels as compared to 0% of the NTCs (p=0.029). No significant correlation was found between blood serum lactate levels and MRS-derived Lac+ levels. LIMITATIONS: A cautious interpretation of our results is warranted due to a p value of 0.028. In addition, a higher than anticipated proportion of data sets had to be excluded due to poor spectral quality. CONCLUSION: This study confirms the presence of elevated cerebral Lac+ levels in a subgroup of adults with ASD, suggesting the potential of lactate as a biomarker for mitochondrial dysfunction in a subgroup of ASD. The lower-than-expected prevalence (20% was expected) and moderate increase require further investigation to elucidate the underlying mechanisms and relationships with mitochondrial function.

Increased prefrontal GABA concentrations in adults with autism spectrum disorders / Simon MAIER in Autism Research, 15-7 (July 2022)  

Public ISBD [article]  inAutism Research > 15-7 (July 2022) . - p.1222-1236 Titre : Increased prefrontal GABA concentrations in adults with autism spectrum disorders Type de document : texte imprimé Auteurs : Simon MAIER, Auteur ; Ansgard Lena DÃœPPERS, Auteur ; Kimon RUNGE, Auteur ; Michael DACKO, Auteur ; Thomas LANGE, Auteur ; Thomas FANGMEIER, Auteur ; Andreas RIEDEL, Auteur ; Dieter EBERT, Auteur ; Dominique ENDRES, Auteur ; Katharina DOMSCHKE, Auteur ; Evgeniy PERLOV, Auteur ; Kathrin NICKEL, Auteur ; Ludger TEBARTZ VAN ELST, Auteur Article en page(s) : p.1222-1236 Langues : Anglais (eng) Mots-clés : Gaba  anterior cingulate cortex  autism spectrum disorder  dorsolateral prefrontal cortex  gamma-aminobutyric acid  glutamate Index. décimale : PER Périodiques Résumé : The excitatory-inhibitory imbalance hypothesis postulates dysregulation of the gamma-aminobutyric acid (GABA) and glutamate (Glu) neurotransmitter systems as a common underlying deficit in individuals with autism spectrum disorders (ASD). Previous studies suggest an important role of these systems in the pathophysiology of ASD, including a study of our group reporting decreased glutamate concentrations in the pregenual anterior cingulate cortex (ACC) of adults with ASD. The aim of this study was to replicate our previous findings of impaired glutamate metabolism in ASD in a new sample and to additionally quantify GABA in the ACC and dorsolateral prefrontal cortex (dlPFC). Concentrations of GABA and glutamate-glutamine (Glx; combined glutamate and glutamine signal) were quantified in the ACC and dlPFC of 43 adults with ASD and 43 neurotypical controls (NTC) by magnetic resonance spectroscopy (MRS). The ASD group showed increased absolute GABA concentrations and elevated GABA/creatine ratios in the left dlPFC compared to NTC, while no group differences were detected in the pregenual and dorsal ACC. Previous findings of altered Glx concentration in the pregenual ACC of the ASD group could not be replicated. Regarding Glx concentrations and Glx/creatine ratios, there were no significant differences in the dlPFC and ACC either. The study supports the hypothesis of an altered GABA and glutamate equilibrium, indicating an imbalance between excitatory and inhibitory metabolism in ASD patients. However, inconsistent results across studies and brain regions suggest a complex underlying phenomenon. LAY SUMMARY: Adults of the autism spectrum exhibit elevated levels of the inhibitory neurotransmitter GABA in the left dorsolateral prefrontal cortex. This finding supports the hypothesis of an imbalance between excitatory and inhibitory equilibrium in patients with autism spectrum disorders.

Linking Brain Morphometry to Psychometric Measures and Energy-Metabolic Biomarkers in Adults With Autism Spectrum Disorder / Eleonora ESPOSTO in Autism Research, 19-7 (July 2026)

This study investigates the link between brain structure, psychometric measures, and both central and peripheral metabolic biomarkers in adults with ASD. We studied 145 adults, including 74 with ASD and 71 control participants (CON) using high-resolution 3-Tesla MRI to assess cortical thickness, subcortical and global brain volumes. Central energy metabolism was indexed by the posterior-cingulate lactate?+?threonine (Lac+) peak quantified with proton-MRS. We examined associations between biomarkers of mitochondrial function and energy metabolism (including lactate, pyruvate, creatine kinase, and multiple acylcarnitines). Psychometric evaluations included measures of ASD and attention-deficit/hyperactivity disorder (ADHD) symptom severity, as well as other psychiatric comorbidities. Between-group differences and correlations were assessed using robust statistics, controlling for age, sex, image quality, and total intracranial volume. Adults with ASD showed significantly larger bilateral caudate volumes compared to CON. Within the ASD group, higher ADHD symptom severity in childhood correlated with reduced cortical thickness in multiple frontal and temporal regions. Among metabolic markers, acylcarnitine C5:1 was positively associated with right insular cortex thickness, while C18:1-OH and C18:2 levels correlated positively with caudate volume. Caudate nucleus volume is associated not only with an ASD diagnosis but also with specific peripheral energy-metabolism blood markers, such as specific acylcarnitines. Alterations in cortical thickness were also correlated with acylcarnitine levels and, to a greater extent, with co-occurring ADHD symptoms. While alterations in cortical thickness and basal ganglia structure have been previously described in ASD and comorbid ADHD, the linkage between mitochondrial and energy metabolism biomarkers with neuroanatomical alterations in ASD is, to our knowledge, a novel observation that warrants further investigation.
