People with depression and anxiety are more likely to have manic depression or manic bipolar disorder than people who don’t have either condition, according to new research.
The findings, published in the Journal of Affective Disorders, indicate that people with depression are more vulnerable to depression than those without it.
“People with depression often don’t see their mental health problems as being their own,” said Dr. Peter H. Klein, a professor of psychiatry at Columbia University and an author of the study.
“They think of it as something that’s happening to them, and they may not even know they’re experiencing it.”
Klein and his colleagues recruited patients who were either depressed or anxious about their moods.
The researchers then asked the patients about their depression and depression symptoms, and how well they thought they would be able to cope with it.
Patients with bipolar disorder were more likely than people with a depression diagnosis to report experiencing symptoms that could be characterized as manic depression.
“For those with bipolar disorders, it may be hard to know whether they have depression or bipolar disorder,” Klein said.
“It’s a pretty common finding, but it hasn’t been known whether depression is a symptom or not.”
The findings suggest that depression is linked to other mental health disorders, including anxiety and obsessive-compulsive disorder, Klein said, but more research is needed to better understand the relationship between depression and those other disorders.
The findings also suggest that people who are depressed may also be at risk for developing bipolar disorder, but those people aren’t necessarily more likely.
“There’s no evidence that having depression or being depressed makes you more likely or more likely of developing bipolar or depressive disorders,” Klein noted.
“We need to understand how depression and other mental disorders are associated and how they relate to one another.”
The study also examined whether depression and manic depression were related to how people think and behave in real life.
The study found that depressed people are more open about their thoughts and emotions, which may make them less likely to engage in risky behavior, such as substance abuse or criminal behavior.
People with bipolar and depressive disorders also reported experiencing more negative emotions, such a guilt or shame, compared to people who weren’t depressed.
The researchers say their findings don’t provide a cause-and-effect relationship between the two conditions.
Instead, they say it’s possible that people experiencing depression and thinking about being depressed may be less likely than others to seek help from mental health professionals.
The new findings are the first to investigate how depression affects a person’s perception of their own health and mental health.
Previous research has linked depressive symptoms to lower self-esteem, which can be linked to poorer self-regulatory behaviors, Klein explained.
The new study adds to previous research showing that depression and suicidal thoughts may lead to feelings of guilt and shame that can make people more anxious, Klein added.
“The more we know about the link between depression, depression, and suicidal behavior, the more we can understand why that link exists,” Klein added, adding that it may help prevent suicidal thoughts in people with mental health issues.
