Their results showed that AF was associated with smaller
frontal lobe volumes, even after adjusting for age, gender, vascular risk factors and APOE4 (a gene independently linked to smaller brain volumes).
The researchers examined total cerebral volume,
frontal lobe volume, temporal lobe volume, hippocampal volume and white matter hyper - intensity volume in patients without prior stroke or dementia.
According to a recent Framingham Heart Study, people who experience the heart arrhythmia atrial fibrillation (AF), may also suffer from a smaller brain, specifically reduced
frontal lobe volume.
Obese Adolescents with Type 2 Diabetes Mellitus Have Hippocampal and
Frontal Lobe Volume Reductions
Not exact matches
When Thompson's team looked at brain scans of 206 healthy people aged 70 to 80, they found that those with at least one copy of the FTO variant had 8 per cent less
volume in their
frontal lobes and 12 per cent less in the occipital
lobes, compared with their counterparts lacking the variant.
«Association discovered between atrial fibrillation, reduced
frontal lobe brain
volumes.»
The scientists found that an area in the lower
frontal lobe, the so - called orbitofrontal cortex, exhibited smaller
volumes in the healthy individuals that reported that they have problems with regulating emotions.
Increases in working memory - related activation
volume of 82, 73, 83, and 36 % were observed in the left
frontal, right
frontal, left parietal, and right parietal
lobes, respectively, for 3 T compared with 1.5 T.
Higher expenditure of energy was associated with larger gray matter
volumes in the parietal, temporal and
frontal lobes, which included the basal ganglia, posterior cingulate and hippocampus.
For the
frontal lobe, we observe a statistically significant association with growth and
volume, with initial evidence suggesting
volume, rather than growth, has a stronger influence on externalizing symptoms for low SES children (
volume β = − 0.000158, p =.049; growth β = − 0.00138, p =.045).
Given the importance of the
frontal lobe in behavioral regulation [50], we also hypothesized that variations in this brain area (both in regards to lower
volume and slower growth) would be related to greater disruptive behavioral problems in children (as measured by the Child Behavior Checklist, CBCL).
