Recovery from depression
might take longer among adults who suffered childhood
abuse or had parents with addiction problems, a new study suggests.
University of Toronto researchers analysed data from more than 1 100
Canadian adults with depression who were assessed every other year until they
recovered, for up to 12 years.
"Our findings indicated that most people bounce back," study
co-author Tahany Gadalla, professor emerita, said in a university news release.
"Three-quarters of individuals were no longer depressed after two
in 10 in SA has addiction problem
There was, however, wide variation in how long patients took to recover,
lead author Esme Fuller-Thomson, of the university's Faculty of Social Work,
said in the news release.
"Early adversities have far-reaching consequences," Fuller-Thomson
said. "The average time to recovery from depression was nine months longer
for adults who had been physically abused during their childhood and about five
months longer for those whose parents had addiction problems."
The study was published in the journal Social
Psychiatry and Psychiatric Epidemiology.
Study co-author Marla Battiston added: "Numerous studies have shown
that childhood abuse and parental addictions make individuals more vulnerable
to depression. Our research highlights that these factors also slow the
recovery time among those who become depressed."
The study did not determine why these childhood events are linked with slow
recovery from depression, but the researchers suggested that these negative
experiences might interrupt the normal development of a brain network involved
in stress regulation.
Although the study found an association between childhood abuse, parental
addictions and a person's vulnerability to slow recovery time from depression,
it did not prove a cause-and-effect relationship.
