Pro-atherogenic medical conditions are associated with widespread regional brain metabolite abnormalities in those with alcohol use disorder. Alcohol Alcohol 2024; 59:agae055. [PMID: 39127890 DOI: 10.1093/alcalc/agae055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Revised: 07/24/2024] [Accepted: 07/31/2024] [Indexed: 08/12/2024] Open
Abstract
AIMS Widespread brain metabolite abnormalities in those with alcohol use disorder (AUD) were reported in numerous studies, but the effects of the pro-atherogenic conditions of hypertension, type 2 diabetes mellitus, hepatitis C seropositivity, and hyperlipidemia on metabolite levels were not considered. These conditions were associated with brain metabolite abnormalities in those without AUD. We predicted treatment-seeking individuals with AUD and pro-atherogenic conditions (Atherogenic+) demonstrate lower regional metabolite markers of neuronal viability [N-acetylaspartate (NAA)] and cell membrane turnover/synthesis [choline-containing compounds (Cho)], compared with those with AUD without pro-atherogenic conditions (Atherogenic-) and healthy controls (CON). METHODS Atherogenic+ (n = 59) and Atherogenic- (n = 51) and CON (n = 49) completed a 1.5 T proton magnetic resonance spectroscopic imaging study. Groups were compared on NAA, Cho, total creatine, and myoinositol in cortical gray matter (GM), white matter (WM), and select subcortical regions. RESULTS Atherogenic+ had lower frontal GM and temporal WM NAA than CON. Atherogenic+ showed lower parietal GM, frontal, parietal and occipital WM and lenticular nuclei NAA level than Atherogenic- and CON. Atherogenic- showed lower frontal GM and WM NAA than CON. Atherogenic+ had lower Cho level than CON in the frontal GM, parietal WM, and thalamus. Atherogenic+ showed lower frontal WM and cerebellar vermis Cho than Atherogenic- and CON. CONCLUSIONS Findings suggest proatherogenic conditions in those with AUD were associated with increased compromise of neuronal integrity and cell membrane turnover/synthesis. The greater metabolite abnormalities observed in Atherogenic+ may relate to increased oxidative stress-related compromise of neuronal and glial cell structure and/or impaired arterial vasoreactivity/lumen viability.

Mil Med 2024; 189:e1064-e1071. [PMID: 37897693 DOI: 10.1093/milmed/usad405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 09/12/2023] [Accepted: 09/29/2023] [Indexed: 10/30/2023] Open
Abstract
INTRODUCTION Lifetime and past-year alcohol use disorder (AUD) prevalence is significantly higher in US Armed Services Veterans than in non-veterans across adulthood. This study examined the associations of perceived transformational leadership styles (TLS) experienced during military service and anhedonic depression and self-efficacy related to confidence to abstain or reduce alcohol consumption in Veterans seeking treatment for AUD. The ramifications of perceived leadership styles on multiple aspects of follower psychiatric functioning, including depressive and PTSD symptomatology, during and after military service, may be substantial and enduring. Higher anhedonic depression and lower abstinence self-efficacy are related to increased risk of relapse after treatment. We predicted Veterans, in treatment for AUD, who reported higher perceived levels of transformational leadership during military service, demonstrate lower anhedonic depressive symptoms and higher alcohol abstinence self-efficacy. MATERIALS AND METHODS Veterans with AUD (n = 60; 50 ± 14 years of age) were recruited from residential treatment at the VA Palo Alto Health Care System. All procedures were approved by the VA Palo Alto Health Care System and Stanford University institutional review boards. A series of mediation analyses were completed with The Multifactor Leadership Questionnaire measures of TLS (average across leadership measures [transformational leadership average; TLS average]) as predictor and the Alcohol Abstinence Self-Efficacy Scale, Mood and Anxiety Symptom Questionnaire, anhedonic depression subscale, as dependent measures. PTSD Checklist for DSM-5 score was tested as a mediator variable. RESULTS Higher reported perceived TLS average during military service was significantly related to lower anhedonic depressive symptoms. Higher TLS average was related to higher self-efficacy to resist alcohol use in contexts involving experience of physical issues and withdrawal/cravings and urges. These relationships were not mediated by PTSD symptomatology or duration of military service, age, education, time since military service, military branch, combat exposure, or current psychiatric diagnosis. CONCLUSIONS The significant associations of perceived TLS during military service with anhedonic depression and alcohol use self-efficacy are clinically relevant because these measures are associated with relapse risk after AUD treatment. Further study of the implications of perceived TLS during military service for AUD and other substance use disorder treatment outcome is warranted in Veterans.

Durazzo TC, Stephens LH, Meyerhoff DJ. Regional cortical thickness recovery with extended abstinence after treatment in those with alcohol use disorder. Alcohol 2024; 114:51-60. [PMID: 37657667 PMCID: PMC10902196 DOI: 10.1016/j.alcohol.2023.08.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 07/31/2023] [Accepted: 08/22/2023] [Indexed: 09/03/2023]
Abstract
Several cross-sectional investigations reported widespread cortical thinning in those with alcohol use disorder (AUD). The few longitudinal studies investigating cortical thickness changes during abstinence are limited to the first month of sobriety. Consequently, cortical thickness changes during extended abstinence in those with AUD is unclear. In this study, AUD participants were studied at approximately 1 week (n = 68), 1 month (n = 88), and 7.3 months (n = 40) of abstinence. Forty-five never-smoking controls (CON) completed a baseline study, and 15 were reassessed after approximately 9.6 months. Participants completed magnetic resonance imaging studies at 1.5T, and cortical thickness for 34 bilateral regions of interest (ROI) was quantitated with FreeSurfer. AUD participants demonstrated significant linear thickness increases in 25/34 ROI over 7.3 months of abstinence. The rate of change from 1 week to 1 month was greater than 1 month to 7.3 months in 19/34 ROIs. Proatherogenic conditions were associated with lower thickness recovery in anterior frontal, inferior parietal, and lateral/mesial temporal regions. After 7.3 months of abstinence, AUD participants were statistically equivalent to CON on cortical thickness in 24/34 ROIs; the cortical thickness differences between AUD and CON in the banks superior temporal gyrus, post central, posterior cingulate, superior parietal, supramarginal, and superior frontal cortices were driven by thinner cortices in AUD with proatherogenic conditions relative to CON. In actively smoking AUD, increasing pack-years was associated with decreasing thickness recovery primarily in the anterior frontal ROIs. Widespread bilateral cortical thickness recovery over 7.3 months of abstinence was the central finding for this AUD cohort. The longitudinal and cross-sectional findings for AUD with proatherogenic suggests alterations in perfusion or vascular integrity may relate to structural recovery in those with AUD. These results support the adaptive and beneficial effects of sustained sobriety on brain structural recovery in people with AUD.

May AC, Meyerhoff DJ, Durazzo TC. Non-abstinent recovery in alcohol use disorder is associated with greater regional cortical volumes than heavy drinking. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2023; 47:1850-1858. [PMID: 37864525 DOI: 10.1111/acer.15169] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 07/14/2023] [Accepted: 08/02/2023] [Indexed: 10/23/2023]
Abstract
BACKGROUND Harm-reduction (i.e., non-abstinent recovery) approaches to substance use treatment have garnered increasing attention. Reduced levels of alcohol consumption post-treatment have been associated with better psychosocial functioning and physical health, yet less is known regarding differences in brain structures associated with varying levels of alcohol consumption. This study investigated regional cortical volumes after alcohol use disorder (AUD) treatment among individuals who achieved complete abstinence and those who returned to lower and higher levels of consumption. METHODS Data were collected from individuals with AUD (n = 68) approximately 8 months after the initiation of treatment. Using risk drinking levels defined by the World Health Organization, participants were classified as abstaining (AB) or relapsing with low (RL) or higher (RH) levels. Data were also obtained from 34 age-matched light/non-drinking controls (LN). All participants completed a 1.5 T magnetic resonance imaging session and volumes for 34 bilateral cortical regions of interest were quantitated with FreeSurfer. Generalized linear models were used to examine group differences in cortical volume. All group findings are significant at an FDR-corrected value of 0.018. RESULTS Adjusting for age and intracranial volume, significant group differences were found in 13/34 cortical regions. AB showed greater volumes than RL in 2/13 regions and RH in 6/13 regions. RH demonstrated significantly smaller volumes than LN in 12/13 ROIs, whereas RL differed from LN in 9/13 regions. RH and RL differed in only two cortical regions. CONCLUSIONS Individuals who consumed low-risk levels of alcohol post-treatment exhibited regional cortical volumes more similar to abstainers than individuals who returned to higher-risk levels. This suggests that low-risk levels of alcohol consumption are associated with brain integrity that is comparable to that seen with complete abstinence. Given the previously demonstrated improvement in psychosocial and physical health with reduced levels of alcohol consumption post-treatment, harm reduction may be a beneficial and more attainable goal for some individuals with AUD who are seeking treatment.

Abstract
Introduction Studies have found a varying degree of cognitive, psychosocial, and functional impairments in patients with unruptured intracranial aneurysms (UIAs), whereas the neural correlates underlying these impairments remain unknown. Methods To examine the brain morphological alterations and white matter lesions in patients with UIA, we performed a range of structural analyses to examine the brain morphological alterations in patients with UIA compared with healthy controls (HCs). Twenty-one patients with UIA and 23 HCs were prospectively enrolled into this study. Study assessment consisted of a brain magnetic resonance imaging (MRI) scan with high-resolution T1-weighted and T2-weighted imaging data, a Montreal Cognitive Assessment (MoCA), and laboratory tests including blood inflammatory markers and serum lipids. Brain MRI data were processed for cortical thickness, local gyrification index (LGI), volume and shape of subcortical nuclei, and white matter lesions. Results Compared to the HCs, patients with UIA showed no significant differences in cortical thickness but decreased LGI values in the right posterior cingulate cortex, retrosplenial cortex, cuneus, and lingual gyrus. In addition, decreased LGI values correlated with decreased MoCA score (r = 0.498, p = 0.021) and increased white matter lesion scores (r = -0.497, p = 0.022). The LGI values were correlated with laboratory values such as inflammatory markers and serum lipids. Patients with UIA also showed significant regional atrophy in bilateral thalami as compared to the HCs. Moreover, the LGI values were significantly correlated with thalamic volume in the HCs (r = 0.4728, p = 0.0227) but not in the patients with UIA (r = 0.11, p = 0.6350). Discussion The decreased cortical gyrification, increased white matter lesions, and regional thalamic atrophy in patients with UIA might be potential neural correlates of cognitive changes in UIA.

BDNF rs6265 Met carriers with alcohol use disorder show greater age-related decline of N-acetylaspartate in left dorsolateral prefrontal cortex. Drug Alcohol Depend 2023; 248:109901. [PMID: 37146499 DOI: 10.1016/j.drugalcdep.2023.109901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 04/04/2023] [Accepted: 04/25/2023] [Indexed: 05/07/2023]
Abstract
BACKGROUND Brain-derived neurotrophic factor (BDNF) is implicated in neuronal and glial cell growth and differentiation, synaptic plasticity, and apoptotic mechanisms. A single-nucleotide polymorphism of the BDNF rs6265 gene may contribute to the pattern and magnitude of brain metabolite abnormalities apparent in those with an Alcohol Use Disorder (AUD). We predicted that Methionine (Met) carriers would demonstrate lower magnetic resonance spectroscopy (MRS) measures of N-acetylaspartate level (NAA) and greater age-related decline in NAA than Valine (Val) homozygotes. METHODS Veterans with AUD (n=95; 46±12 years of age, min = 25, max = 71) were recruited from VA Palo Alto residential treatment centers. Single voxel MRS, at 3 Tesla, was used to obtain NAA, choline (Cho) and creatine (Cr) containing compounds from the left dorsolateral prefrontal cortex (DLPFC). Metabolite spectra were fit with LC Model and NAA and Cho were standardized to total Cr level and NAA was also standardized to Cho. RESULTS Val/Met (n=35) showed markedly greater age-related decline in left DLPFC NAA/Cr level than Val/Val (n=60); no differences in mean metabolite levels were observed between Val/Met and Val/Val. Val/Met demonstrated greater frequency of history of MDD and higher frequency of cannabis use disorder over 12 months prior to study. CONCLUSIONS The greater age-related decline in left DLPFC NAA/Cr and the higher frequency of MDD history and Cannabis Use disorder in BDNF rs6265 Met carriers with AUD are novel and may have implications for non-invasive brain stimulation targeting the left DLFPC and other psychosocial interventions typically utilized in the treatment of AUD.

Abstract
AIMS The goal of this study was to determine if active cigarette smoking in Veterans with alcohol use disorder (AUD) was associated with greater age-related neurocognitive decline. METHODS Veterans with AUD, in residential treatment (n = 125; 47 ± 14 years of age, min = 24, max = 76, 29 ± 26 days of abstinence), completed measures of executive functions, learning and memory, processing speed and working memory. Actively smoking AUD (AsAUD, n = 47) were active daily cigarette smokers; former smoking AUD (FsAUD, n = 45) were predominately daily smokers prior to study but did not smoke at the time of study; non-smoking AUD (NsAUD, n = 33) never used cigarettes or smoked 'only a few times' during lifetime. RESULTS AsAUD demonstrated greater age-related decline on measures of visuospatial learning and memory, and response inhibition/cognitive flexibility, primarily relative to NsAUD; there were no age-related differences between FsAUD and NsAUD on any measure. There were few significant mean differences between groups across the 15 neurocognitive measures. In AsAUD, higher scores on indices of smoking severity were associated with poorer performance on measures of auditory-verbal learning and memory, response inhibition, set-shifting and working memory. In FsAUD, longer smoking cessation duration was related to lower PTSD, anxiety and depressive symptomatology. CONCLUSIONS Active smoking was associated with accelerated age-related decline on cognitive functions implicated in response to common evidence-based AUD interventions. Results suggest that smoking history contributes to the considerable heterogeneity observed in neurocognitive function in early AUD recovery, and reinforce the clinical movement to offer smoking cessation resources concurrent with treatment for AUD.

Lower regional grey matter in alcohol use disorders: evidence from a voxel-based meta-analysis. BMC Psychiatry 2021; 21:247.

Abstract
BACKGROUND Previous research using whole-brain neuroimaging techniques has revealed structural differences of grey matter (GM) in alcohol use disorder (AUD) patients. However, some of the findings diverge from other neuroimaging studies and require further replication. The quantity of relevant research has, thus far, been limited and the association between GM and abstinence duration of AUD patients has not yet been systematically reviewed. METHODS The present research conducted a meta-analysis of voxel-based GM studies in AUD patients published before Jan 2021. The study utilised a whole brain-based d-mapping approach to explore GM changes in AUD patients, and further analysed the relationship between GM deficits, abstinence duration and individual differences. RESULTS The current research included 23 studies with a sample size of 846 AUD patients and 878 controls. The d-mapping approach identified lower GM in brain regions including the right cingulate gyrus, right insula and left middle frontal gyrus in AUD patients compared to controls. Meta-regression analyses found increasing GM atrophy in the right insula associated with the longer mean abstinence duration of the samples in the studies in our analysis. GM atrophy was also found positively correlated with the mean age of the samples in the right insula, and positively correlated with male ratio in the left middle frontal gyrus. CONCLUSIONS GM atrophy was found in the cingulate gyrus and insula in AUD patients. These findings align with published meta-analyses, suggesting they are potential deficits for AUD patients. Abstinence duration, age and gender also affect GM atrophy in AUD patients. This research provides some evidence of the underlying neuroanatomical nature of AUD.
