poorer familial relationships, anxiety, and depression are thepotential predictors of adolescents’ Internet addiction
Correlation vs causation on this issue? Wonder what other factors are at play with this issue.

Methods
Things of note/interest: - Females aged 4.2 years within lockdown which is correlated with their higher rates of mental health issues - 36 lobes affected in females only 2 affected in males - mostly visual and social processing are affected in this - This seems to be most studied in preteens and teens - Not much research into how external factors affect these things (socioeconomic class, household stability, etc.) - Huge interest in how much of a role the internet and media played in all of this.
-
Cortical thickness
the measurement of the thickness of the outer layer of the brain, known as the cortex
-
to young adults.
I also wonder if adults/people with fully developed brains experienced anything like this, and if so how would we measure it?
-
First, the size of the sample measured here is smallrelative to several ongoing large-scale multisite studies of adolescentbrain development, some of which collected data both before andafter the pandemic
I was wondering about this, perhaps this sample was particularly skewed due to a smaller sample size? Nevertheless I think the findings are still important and interesting!

The effect of the resulting isolation on the needs ofmale and female adolescents may have been very different, withfemales perhaps experiencing more stress than males associatedwith this prolonged isolation, resulting in a larger cascade ofphysiological effects. Our finding that regions associated withsocial cognition were the most affected in females are consistentwith this hypothesis.
Because male friendships rely on shared activities they still had access to that in the pandemic from doing things outside while distanced, playing video games together or just texting.
-
emotional circuits
Desire, anger, anxiety, sex, nurture, grief and play systems are all examples of this
-
processing of faces
Both sexes show a maturing of facial recognition, which I find quite interesting given how everyone was inside without peers around. Makes me wonder how much of a role the internet played in this and if we would have seen this in a pandemic like the Spanish Flu or Bubonic Plague.
-
left superior temporal cortex
Language comprehension and processing located in the temporal lobe
-
left insula
In charge of empathy located in the fissure separating the temporal lobe from the parietal and frontal lobes
-
bilateral fusiform
Refers to Fusiform Gyrus which is responsible for higher processing of visual information, and identifying objects. Located on the occipital lobe
-
difference between the age predicted by the model and actual agein the post-COVID-19 lockdown test sample was 4.2 y
a single lockdown aging someone 4 years

One study of 9- to13-y-old subjects reported accelerated maturation of the medialprefrontal cortex, as reflected by a reduction in cortical thicknessover what would be expected from normal aging, and accelerateddevelopment of the hippocampus, as reflected in an increase inhippocampal volume (13). A study of 16-y-old adolescents reportedreduced average brain cortical thickness and larger bilateral hip-pocampal and amygdala volumes
This is shown to also happen in cases of stress or trauma in adolescent's brains
-
only in the occipitallobe.
Very curious about why males only seem to mature faster when it comes to visuals? Tied to gaming or media consumption? Look into this more if paper doesn't answer
-
Myelination
Helps neurons fire faster/better (like insulated wiring)

low SES environment is linked toaccelerated brain development
Linked to everything from depression to Alzheimer's, overall sounds dope but isn't great.
