This Is The Mental Hallmark Of Depression

This Is The Mental Hallmark Of Depression post image

Why negative thoughts make some people depressed, while others quickly dismiss them.

“Sticky thoughts” are the hallmark of depression, research finds.

Bad things happen to most of us at some point, but some people take it worse than others.

This is partly down to the inability to mentally turn away from them.

Thoughts about negative experiences can get ‘stuck’ in the brain.

Professor Jutta Joormann, the study’s first author, explained what happens in the minds of depressed people:

“They basically get stuck in a mindset where they relive what happened to them over and over again.

Even though they think, oh, it’s not helpful, I should stop thinking about this, I should get on with my life — they can’t stop doing it.”

The researchers compared the working memory of 26 people diagnosed with depression to 27 people who were depression-free.

Working memory refers to the thoughts that are active in your mind at this very moment.

Our present-moment experience, therefore, is highly dependent on how our working memory operates.

All the people in the study did a test that required them to think flexibly.

In other words, it required them to turn their attention from one subject to another.

The results showed that depressed people had particular problems turning their minds away from negative thoughts.

For example, if they were reminded of ‘death’ or ‘sadness’, their minds got stuck on these ideas and couldn’t change to focus on something else.

Professor Joormann said:

“The order of the words sort of gets stuck in their working memory, especially when the words are negative.”

People who were susceptible to getting these ‘stuck thoughts’ were also likely to ruminate more on their problems.

One way out of this trap is to first, learn to notice when this is happening.

Secondly, it is vital to refocus the attention elsewhere.
