Proactively avoiding an association that triggers an unwanted thought or memory is more effective than reactive control is more effective when trying to prevent repetitive looping of unwanted thoughts.
Negative metacognitions and rumination can exacerbate symptoms of depression, researchers say.
Ten minutes of idle thought can tell us a lot about the potential risk of depression, researchers say. Those who tend to ruminate and were more past or negatively focused in their idle thoughts had an increased risk of depression.
If you want to conjure a new thought in your mind, you have to force yourself to stop ruminating on old thoughts. The insight could help with the treatment of PTSD and other disorders associated with rumination.
Researchers have uncovered the neural mechanism underlying rumination. The study reports when rumination occurs, coupling between the core and medial temporal lobe subsystems of the default mode network becomes elevated, while coupling between the core and dorsomedial prefrontal cortex decreases.
Repetitive negative thinking (RNT) in those aged over 55 is associated with an increased risk of cognitive decline and deposition of proteins associated with Alzheimer's disease. People who exhibited higher levels of RNT experienced more cognitive and memory problems over four years. They were more likely to have both amyloid-beta and tau protein deposits throughout the brain.
Using metacognitive therapy to reduce rumination can help relieve symptoms of depression, a new study reports.
