abstract = {To assess the relationship between ultrasonographic changes
in midbrain structures and subsequent violent suicidal
behavior.We conducted a retrospective analysis of a
previously reported cohort of 46 patients (36 women; age
54.9 ± 11.7 years) with major depression who had been
prospectively observed over a ten-year period to assess the
risk of developing Parkinson's disease. At study entry, all
patients underwent transcranial B-mode sonography to grade
the echogenicity of the midbrain raphe and substantia nigra.
The outcome measure was the first occurrence of violent
suicidal behavior, i.e. a serious suicide attempt or
completed suicide.At baseline, four patients were found to
have grade 1 raphe echogenicity (invisible), 23 had grade 2
(weakly echogenic), and 19 had normal grade 3 (strongly
echogenic). The visually graded echogenicity correlated well
with the digitally analyzed echo-intensity (p < 0.001).
Three $(75\%)$ patients with echogenicity grade 1
subsequently attempted or completed suicide, as did five
$(22\%)$ with grade 2, but none with grade 3 (Kaplan-Meier
analysis, log-rank test, p < 0.001). The latency period did
not differ between echogenicity grade 1 and 2 (34.7 ± 30.9
vs. 22.6 ± 19.7 months, p = 0.59). Overall, patients with
reduced raphe echogenicity were less likely to be free of
subsequent violent suicidal behavior (3 years: RR, 0.78;
$95\%$ CI, 0.64-0.95; p = 0.034; 10 years: 0.70; 0.55-0.90;
p = 0.014). No sex differences were found. Echogenicity of
the substantia nigra did not improve the prediction of
suicidal behavior.Reduced echogenicity of the midbrain raphe
indicates an increased risk of subsequent violent suicidal
behavior in patients with major depression.},
