The Claim
Adolescents with nonsuicidal self-injury and comorbid depression exhibit significant hypoactivation of the ventral striatum during reward anticipation.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adolescents who engage in nonsuicidal self-injury and have depression show reduced activity in the ventral striatum when expecting a reward.
See the scientific wording
Neuroimaging studies consistently show that adolescents with nonsuicidal self-injury and comorbid depression exhibit significant hypoactivation of the ventral striatum during reward anticipation, suggesting a neural basis for anhedonia in this population.
In adolescents with nonsuicidal self-injury and depression, the brain's reward center does not respond properly when expecting something good because dopamine signals are weak and the connection between the thinking part of the brain and the reward center is broken. This makes them feel empty and numb, so they hurt themselves to trigger a strong chemical surge that briefly fills the void.
What the research says
1 studyThis study says that teens who hurt themselves and feel empty or numb often have a brain reward system that doesn’t light up when they expect something good — which might explain why they don’t feel pleasure. It uses existing brain scan data to back this up.
