Group | Vermis (Mean ± SD) | Vermis Normalized to Total Cerebral Volume (Mean ± SD) |
---|---|---|
Healthy volunteers (n = 8) | 8734 ± 1256 | 0.065 ± 0.006 |
Parents (n = 10) | 8496 ± 1035 | 0.060 ± 0.009 |
Affected subjects (n = 7) | 7427 ± 1427 | 0.056 ± 0.011b |
Cubic centimeters.
F ratio 2.79, P = .08 indicate a trend for affected subjects to have a smaller cerebellar vermis, with no effect of age (P > .20).
