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.
