Temporal Dynamic Changes in Functional Connectivity of Reward Network in Depressed Adolescents and Young Adults with and without Suicidal Attempts
Abstract
The
prevalence
of
depression
has
sharply
increased
among
adolescents
and
young
adults
over
the
past
decade.
Depression
in
adolescence
adulthood
raised
growing
concern
because
it
is
associated
with
an
risk
suicide,
thus
heightening
likelihood

suicide.
However,
neurobiological
underpinnings
depressed
remain
poorly
understood.
In
this
study,
we
investigated
dynamic
functional
connectivity
(dFC)
between

using

Our
findings
revealed
significant

including

These
results
demonstrate
that

suggesting
such

biomarker
for
