ADHD symptoms correlate with problematic social-media use. Symptom scales do not necessarily indicate confirmed diagnoses, and correlations cannot establish causal direction.

Greater short-form video use is associated with poorer attention and inhibitory control across mixed-age samples. This does not prove screen-induced ADHD or measured dopamine changes.

Total N=1,223; university students and online general-population samples, not selected for ADHD. Some student participants were 17; later online samples were adults. Experiments supported a loop in which boredom prompted switching, while allowing rapid video switching increased boredom and reduced reported engagement or satisfaction in several experiments. More available stimulation did not consistently mean a more satisfying experience. Effects were clearest in student video experiments. Broader samples showed order effects and no overall within-person boredom difference. Brief laboratory exposures, not long-term ADHD trials; no dopamine, addiction or biological-reset measurement.

Analysis of 1,046,857 posts from 4,168 users, plus a 176-person simulated-platform experiment. Counterbalanced low/high like rewards changed posting timing: latencies were approximately 10.9% longer with lower rewards. Supports reward-shaped engagement. Trace users' ages were unverified; the experiment studied posting, not all scrolling. No dopamine, injury, clinical addiction or ADHD measures.

Correlational PET/tap-logging study of 22 healthy adults aged 18–33. Higher proportion of social-app taps, including messaging, associated with lower posterior-putamen dopamine synthesis capacity; absolute social-tap count was not reliably associated. PET was measured once and often months apart from monitoring. Small selected sample; no causal exposure test, synaptic-release measure, neuronal injury or ADHD analysis.

Three online studies pooled 358 adults aged 18–35, mostly students. Self-reported wanting and logo-triggered urges associated with excessive/problematic use; liking was less predictive.

Clinical comparison: 52 adult ADHD patients above a compulsive-internet-use cut-off and 52 matched ADHD patients below it, selected from 169. Greater problematic use accompanied emotional, sleep and functional difficulties; social media was the most common subtype. Cognitive tasks and P300 did not significantly differ. Broad internet-use screening, selected sample and cross-sectional comparison establish neither causation nor dopamine damage. Primary abstract checked; full text restricted.

RCT of 154 adult daily users willing to stop four social platforms for one week versus usual use; 140 completed follow-up. Adjusted wellbeing (+4.9), depressive symptoms (−2.2) and anxiety (−1.7) favoured the break. Reduced self-reported use was corroborated by device records in a subsample. Motivated volunteers, an unblinded comparison and short follow-up limit generalisation. No ADHD selection, addiction treatment or dopamine measurement. Full author copy verified.

Three-week RCT randomised 70 adult iPhone users to personalised reminders or control.

Preregistered cross-sectional study of 111 emerging adults, mean age 21.2, 84% female. Higher self-reported ADHD symptoms were associated with problematic social-media use and gaming.

This community symptom sample was not a diagnosed ADHD cohort; questionnaire associations cannot establish direction or addiction mechanisms. Full institutional author copy verified.

Cohort-pair randomised trial of 133 adults in residential substance treatment. Six hours of ACT replaced usual programming. ACT produced less immediate shame relief but greater reduction at four months, more treatment attendance and lower reported substance use.

Four randomised experiments, mainly undergraduates plus a community adult sample. Compassionate reflection increased improvement and repair motivation. After test failure, study time exceeded no intervention; the self-esteem comparison was marginal and later test scores did not significantly differ.

24.18 links dependent arising, emptiness, dependent designation and the middle way. 8.12 treats actor/action as mutually dependent. 24.38–39 contrasts inherent nature with change and ending suffering.

The preface identifies consulted Tibetan editions and Tsongkhapa's commentary. The document is the literal working translation, distinct from Batchelor's published free poetic version. Terminology varies from Garfield; the same root verses support dependence, contextual designation and the possibility of change. Two translations are two textual witnesses, not independent empirical studies. Wisdomlib's chapter 24 combines root verses with translated Tsongkhapa commentary, which must not be attributed wholesale to Nāgārjuna.

Preregistered random-assignment experiment, final N=194, not an ADHD sample. Effort-contingent versus noncontingent monetary reward during working-memory training increased zygomaticus facial-muscle response after a subsequent unrewarded maths challenge, particularly difficult trials. An exploratory analysis linked that response with liking in the contingent-reward group. Group means for self-reported liking and wanting did not differ, and anticipation/engagement effects were absent. Supports a learned pleasure-related response after effort; no dopamine measurement, reset, ADHD treatment or biological need for suffering.
