Your genes might affect brain wiring more when you're young, but that effect fades as you get older — after 60, it doesn’t seem to matter much anymore.

Brain White Matter Development Is Associated with a Human-Specific Haplotype Increasing the Synthesis of Long Chain Fatty Acids

Cross-Sectional Study

Human

2014 Apr 30

The study found that a gene affecting fatty acid levels has a bigger impact on brain wiring during youth than in old age, which matches the idea that these fats matter more when the brain is growing.

Similar Assertions

Some people have a gene variant that affects how their brain's wiring develops over time — those with the common version (C) show normal brain changes as they age, while those with two copies of the less common version (T) don't show as much change.

People with a certain gene version (TT) might not develop their brain's wiring the same way as others as they age — especially in how it changes in young adulthood and later life — possibly because of how their bodies make certain fats.
