Sleep Duration, Sleep Apnea, and Gray Matter Volume

 This means your doctor has to have AN EXACT SLEEP PROTOCOL FOR YOU.  Not having one is grounds for firing.  You can't lose any more gray matter due to your doctors inability to do their job. I'm not sure sleeping pills would count.

Abstract

This study aimed to evaluate the effect of sleep duration on brain structures in the presence versus absence of sleep apnea in middle-aged and older individuals. The study investigated a population-based sample of 2,560 individuals, aged 49-80 years. The presence of sleep apnea and self-reported sleep duration were examined in relation to gray matter volume (GMV) in total and lobar brain regions. We identified ranges of sleep duration associated with maximal GMV using quadratic regression and bootstrap sampling. A significant quadratic association between sleep duration and GMV was observed in total and lobar brain regions of men with sleep apnea. In the fully adjusted model, optimal sleep durations associated with peak GMV between brain regions ranged from 6.7 to 7.0 hours. Shorter and longer sleep durations were associated with lower GMV in total and 4 sub-regions of the brain in men with sleep apnea.

Regular Fish Consumption and Age-Related Brain Gray Matter Loss

I bet this isn't enough to actually get your hospital diet plan changed to include fish.

You wouldn't want to do anything innovative at all. Sad.

Background

Brain health may be affected by modifiable lifestyle factors; consuming fish and antioxidative omega-3 fatty acids may reduce brain structural abnormality risk.

Purpose

To determine whether dietary fish consumption is related to brain structural integrity among cognitively normal elders.

Methods

Data were analyzed from 260 cognitively normal individuals from the Cardiovascular Health Study with information on fish consumption from the National Cancer Institute Food Frequency Questionnaire and brain magnetic resonance imaging (MRI). The relationship between fish consumption data collected in 1989–1990 and brain structural MRI obtained in 1998–1999 was assessed using voxel-based morphometry in multiple regression analyses in 2012. Covariates were age, gender, race, education, white matter lesions, MRI-identified infarcts, waist–hip ratio, and physical activity as assessed by the number of city blocks walked in 1 week. Volumetric changes were further modeled with omega-3 fatty acid estimates to better understand the mechanistic link between fish consumption, brain health, and Alzheimer disease.

Results

Weekly consumption of baked or broiled fish was positively associated with gray matter volumes in the hippocampus, precuneus, posterior cingulate, and orbital frontal cortex even after adjusting for covariates. These results did not change when including omega-3 fatty acid estimates in the analysis.

Conclusions

Dietary consumption of baked or broiled fish is related to larger gray matter volumes independent of omega-3 fatty acid content. These findings suggest that a confluence of lifestyle factors influence brain health, adding to the growing body of evidence that prevention strategies for late-life brain health need to begin decades earlier.

The First Map Showing All the Connections in Your Brain's White Matter

Gray matter damage is much easier to find, it shows up easily in external affects, hemiparesis, aphasia, etc. This is where I think our doctors are really failing us, they have not mapped 3d damage  to locations in either gray or white matter. I'm sure that my Middle cerebral artery blockage killed off a lot of  my white matter, but there is no known way to even identify the size of the damage. This might give some idea of the effects but it will be 50 years before it becomes standard practice unless a great stroke association directs and plans research to make it useful.
