Your overall brain age is age-appropriate (biological 43.7 vs chronological 44.0), but this global score masks a striking pattern: 65 individual structures show accelerated aging, with a clear left-hemisphere bias—particularly in language and auditory regions.
| Region | Right Flagged | Left Flagged | Pattern |
|---|---|---|---|
| Temporal Lobe | 1 | 8 | Strong left acceleration |
| Insular Cortex | 0 | 5 | Left-only acceleration |
| Frontal Lobe | 8 | 13 | Bilateral, left-dominant |
| Occipital Lobe | 6 | 6 | Bilateral (visual processing) |
| Cerebellum | 0 | 0 | Well preserved |
The top accelerated regions cluster in visual processing (occipital pole +14.7y) and language/auditory areas (planum temporale +10.5y, superior temporal gyrus +10.2y). These are networks associated with reading, verbal processing, and visual analysis.
The left-hemisphere acceleration pattern—especially in temporal and insular regions—suggests a brain that has been heavily used for language-intensive cognitive work. The occipital findings add visual processing to that picture. This is consistent with a career involving extensive reading, writing, verbal reasoning, and screen-based analytical work.
Practical Implication: The preserved cerebellum (prediction/sequencing) combined with accelerated cortical language regions suggests your cognitive infrastructure remains strong, but the verbal processing layers show wear. Strategies that leverage prediction and pattern recognition while reducing verbal working memory load may be particularly effective.
Caveat: Structure-specific brain age is a statistical prediction based on normative models. “Accelerated aging” indicates deviation from population norms, not pathology. Regional wear patterns may reflect heavy use rather than decline.
