A long period of chronic stress can harm a human brain
A note for Lesson no. 5, "Your Brain Secretly Works With Other Brains," in Lisa Feldman Barrett.
Some context from page 91 is:
Simply put, a long period of chronic stress can harm a human brain. Scientific studies are absolutely clear on this point.
Studies show that chronic stress eats away at the brain and the body over the long term regardless of whether the stress stems from ongoing physical abuse, sexual abuse, or verbal aggression. Scientific results like these are surprising and unwelcome, so it’s helpful to consider the evidence in a bit of detail.
Here are references for the various points about chronic stress in this lesson:
- The impact of stress on non-human animals.
- Exposure to verbal abuse was associated with moderate to large impacts on anxiety, depression, and anger during young adulthood.
- Biological impact of growing up in a harsh or chaotic family with a lot of verbal criticism and conflict.
- Swimming in a sea of sustained aggression also places adolescents on a developmental trajectory toward physical and mental illness.
- Link between sustained social stress, usually involving verbal aggression, and an increased incidence of psychiatric and physical disease.
