Depressive symptoms affected 36·0% of this population in 2020. Women, individuals living in rural areas, and residents of western China provinces were particularly affected. Among participants without depressive symptoms, engaging in social media activities at baseline was associated with a 24.0% (95% confidence interval [CI]: 10-36%) lower likelihood of developing depressive symptoms over the next two years. Among depressed participants, compared to individuals not using social media, those initiating three or more social media activities during this period had 1.24 (95% CI: 1.05-1.46) times higher chance of becoming non-depressed, and those using social media all the time were 1·36 (95% CI: 1·09-1·72) times more likely to become non-depressed.

Clinical studies have revealed alterations in behavior as well as in brain structure and function in CACNA1C risk allele carriers. These findings are supported by rodent models of Ca<sub>v</sub>1.2 deficiency, which showed increased anxiety, cognitive and social impairments as well as a shift towards active stress-coping strategies. These behavioral alterations were accompanied by functional deficits, such as reduced long-term potentiation (LTP) and an excitation/inhibition (E/I) imbalance. However, these preclinical studies are largely limited to male rodents, with few studies exploring sex-specific effects. Here, we investigated the effects of Ca<sub>v</sub>1.2 deficiency in forebrain glutamatergic neurons in female conditional knockout (CKO) mice. CKO mice exhibited hyperlocomotion in a novel environment, increased anxiety-related behavior, cognitive deficits, and increased active stress-coping behavior. These behavioral alterations were neither influenced by the stage of the estrous cycle nor by the Nex/Neurod6 haploinsufficiency or Cre expression, which are intrinsically tied to the utilization of the Nex-Cre driver line for conditional inactivation of Cacna1c. In the hippocampus, Ca<sub>v</sub>1.2 inactivation enhanced presynaptic paired-pulse facilitation without altering postsynaptic LTP at CA3-CA1 synapses. In addition, CA1 pyramidal neurons of female CKO mice displayed a reduction in dendritic complexity and spine density.

We employed a semi-supervised representation learning technique known as Surreal-GAN, through which we identified two latent dimensional representations of brain atrophy in symptomatic mild cognitive impairment (MCI) and AD patients: the \"diffuse-AD\" (R1) dimension shows widespread brain atrophy, and the \"MTL-AD\" (R2) dimension displays focal medial temporal lobe (MTL) atrophy. Critically, only R2 was associated with widely known sporadic AD genetic risk factors (e.g., APOE ε4) in MCI and AD patients at baseline. We then independently detected the presence of the two dimensions in the early stages by deploying the trained model in the general population and two cognitively unimpaired cohorts of asymptomatic participants. In the general population, genome-wide association studies found 77 genes unrelated to APOE differentially associated with R1 and R2. Functional analyses revealed that these genes were overrepresented in differentially expressed gene sets in organs beyond the brain (R1 and R2), including the heart (R1) and the pituitary gland, muscle, and kidney (R2). These genes were enriched in biological pathways implicated in dendritic cells (R2), macrophage functions (R1), and cancer (R1 and R2). Several of them were \"druggable genes\" for cancer (R1), inflammation (R1), cardiovascular diseases (R1), and diseases of the nervous system (R2). The longitudinal progression showed that APOE ε4, amyloid, and tau were associated with R2 at early asymptomatic stages, but this longitudinal association occurs only at late symptomatic stages in R1. Our findings deepen our understanding of the multifaceted pathogenesis of AD beyond the brain. In early asymptomatic stages, the two dimensions are associated with diverse pathological mechanisms, including cardiovascular diseases, inflammation, and hormonal dysfunction-driven by genes different from APOE-which may collectively contribute to the early pathogenesis of AD.
