Depression Status

Deficiency of vitamin B6 and vitamin B12, mostly in vegetarians, is found to be associated with depression and adverse neurological function. We investigated whether vitamin B6, B12, and folate have an effect on brain structure, especially among depressed people who follow a specific diet. The study sample comprised 9426 participants from the UK Biobank cohort with a mean age of 62.4 years. A generalized linear model controlling for age, sex, body mass index, ethnicity, town send deprivation index, educational qualification, smoking, and alcohol intake was used to test the association between study groups and structural brain volumes. Depression was more prevalent, and intake of vitamin B6 and B12 was lower among vegetarians, while non-vegetarians had a lower intake of folate. Overall, no significant association was observed between vitamin B6, B12, and folate intakes and both global and subcortical brain volumes among participants with depression. However, vitamin B12 intake was positively associated with right pallidum among non-depressed participants, and a significant interaction between vitamin B12 intake and depression status on the right pallidum was observed. Also, a significant interaction between folate intake and depression status on grey matter (GM) volume and left thalamus was observed. Upon diet stratification, folate intake is associated with total brain volume and GM volume among vegetarians with depression. Furthermore, no significant associations were observed for subcortical regions. Our findings suggest that dietary intake of vitamin B6 and B12 might have an effect on brain structure. Vegetarians, particularly those who suffer from depression may benefit from supplementing their diets with vitamins B6, B12, and folate to ensure brain health. Further studies, especially with a larger sample size and longitudinal design, are needed to confirm these findings.

Abstract Research has shown differences in subcortical brain volumes between participants with schizophrenia and healthy controls. However, none of these differences have been found to associate with schizophrenia polygenic risk. Here, in a large sample (n = 14,701) of unaffected participants from the UK Biobank, we test whether schizophrenia polygenic risk scores (PRS) limited to specific gene-sets predict subcortical brain volumes. We compare associations with schizophrenia PRS at the whole genome level (‘genomic’, including all SNPs associated with the disorder at a p-value threshold < 0.05) with ‘genic’ PRS (based on SNPs in the vicinity of known genes), ‘intergenic’ PRS (based on the remaining SNPs), and genic PRS limited to SNPs within 7 gene-sets previously found to be enriched for genetic association with schizophrenia (‘abnormal behaviour,’ ‘abnormal long-term potentiation,’ ‘abnormal nervous system electrophysiology,’ ‘FMRP targets,’ ‘5HT2C channels,’ ‘CaV2 channels’ and ‘loss-of-function intolerant genes’). We observe a negative association between the ‘abnormal behaviour’ gene-set PRS and volume of the right thalamus that survived correction for multiple testing (ß = −0.031, pFDR = 0.005) and was robust to different schizophrenia PRS p-value thresholds. In contrast, the only association with genomic PRS surviving correction for multiple testing was for right pallidum, which was observed using a schizophrenia PRS p-value threshold < 0.01 (ß = −0.032, p = 0.0003, pFDR = 0.02), but not when using other PRS P-value thresholds. We conclude that schizophrenia PRS limited to functional gene sets may provide a better means of capturing differences in subcortical brain volume than whole genome PRS approaches.

Abstract Purpose Verbal fluency performance has been shown to be sensitive to preclinical cognitive changes in neurodegenerative diseases and may detect early, trauma-related cognitive and volumetric changes amongst professional fighters. Baseline verbal fluency performance and volumes of relevant subcortical brain structures were expected to decline as number of professional fights (NoPF) increased, while controlling for education. Methods Baseline letter and semantic fluency performance, NoPF, and structural brain imaging from 548 active and retired fighters who participated in the Professional Fighters Brain Health Study were considered. ANCOVAs were conducted to assess differences in verbal fluency performance by NOPF, while controlling for years of education. Number of professional fights were stratified into low (0-20 fights), medium (21-40 fights), and high (41 or more fights). Results Semantic fluency performance differed across the three levels of NoPF (F(2, 542)=4.56; p<.02). In addition, significant positive correlations between semantic fluency performance and volumes in the following regions were observed: left thalamus, left putamen, left pallidum, bilateral caudates, bilateral amygdalae, bilateral hippocampi, and bilateral accumbens (all p’s<.05). In contrast, letter fluency performance was not significantly associated with NoPF or volumes of relevant subcortical brain structures (all p’s>.05). Conclusion Semantic fluency may be low-cost, easy-to-administer harbinger of emerging cognitive dysfunction and lower volumes in related subcortical brain regions. Additional assessment of clinical utility is necessary.
