%T Can premorbid episodes of diminished vagal tone be detected via histological markers in patients with PTSD?
%X While 
laboratory 
methods 
for 
estimating 
genetic 
susceptibility 
for 
adult 
psychopathology 
have 
received 
much 
recent 
attention, 
laboratory 
methods 
for 
objectively 
estimating a 
person?s 
early 
autonomic 
nervous 
system 
perturbations 
have 
been 
under-researched. 
Research 
on 
heart 
rate 
variability 
suggests 
that 
early 
life 
episodes 
of 
diminished 
vagal 
tone 
may 
predict 
poor 
stress 
resilience 
in 
adults. 
This 
article 
will 
detail a 
research 
method 
for 
retrospectively 
estimating 
in 
adults 
the 
chronology 
of 
diminished 
vagal 
tone 
episodes 
experienced 
prior 
to 
age 
10. 
This 
method 
makes 
use 
of 
the 
developing 
enamel 
matrix, 
one 
of 
very 
few 
tissues 
that 
cannot 
recover 
after 
being 
stressed.
