Welcome to a new edition of SharpBrains’ e‑newsletter, featuring this time eight scientific reports and industry resources plus a few fun brain teasers.
“Girls who spent less than an hour on screens and boys who spent less than 90 minutes on screens were not negatively impacted by it. But at higher amounts of screen time, their life satisfaction dropped significantly—they were less happy with their lives, and it got worse the more time they spent … (the) study also found that teens who got more regular exercise had greater life satisfaction and fewer physical complaints for both genders. Not only that, the effects were largely unrelated to how much time a teen spent on screens, so that if teens exercised more, it could potentially undo the damage to their well-being that went along with even six or eight hours of screen time.”
#2. Studies find growing evidence linking weight, physical activity, neuroplasticity and depression:
‘Obesity and depression are both major global health challenges, and our study provides the most robust evidence to date that higher BMI causes depression,’ said lead author Jess O’Loughlin. ‘Understanding whether physical or social factors are responsible for this relationship can help inform effective strategies to improve mental health and wellbeing.’
#3. Dr. Judith Beck on the future of cognitive therapy and psychotherapy:
Let’s hope! — “I think Cognitive Behavioral Therapy (CBT) will continue to be adapted for more problems, diagnoses, and conditions. We will train many kinds of caregivers, teachers, front-line workers, police, and even politicians.”
#4. Rationality doesn’t equal efficiency: Cellphone data shows how we navigate cities:
“We discovered that the most predictive model – representing the most common mode of city navigation – was not the quickest path, but instead one that tried to minimize the angle between the direction a person is moving and the line from the person to their destination … Evolution is a story of trade-offs, not optimizations, and the cognitive load of calculating a perfect path rather than relying on the simpler pointing method might not be worth a few saved minutes. After all, early humans had to preserve brain power for dodging stampeding elephants, just like people today might need to focus on avoiding aggressive SUVs.”
#5. Trend: Harnessing digital tech to improve mental health and wellness:
“Designed with the help of Dutch academic Isabela Granic … the game is centred around an avatar who stays in bed for the day and aims to relax players by using soothing music, muted colours and self-care practices. Think meditative tasks such as word games and guided breathing exercises. There’s no way to win, compete or binge – in fact, it deliberately starts to feel boring after a few minutes of play, which disincentivizes mindless scrolling. #SelfCare was an instant hit, garnering half a million downloads in its first six weeks without any advertising…”
#6. Study: Personalized, closed-loop neuromodulation can (one day) become a “pacemaker for the brain”:
“What made this proof-of-principle trial successful was the discovery of a neural biomarker – a specific pattern of brain activity that indicates the onset of symptoms – and the team’s ability to customize a new DBS device to respond only when it recognizes that pattern. The device then stimulates a different area of the brain circuit, creating on-demand, immediate therapy that is unique to both the patient’s brain and the neural circuit causing her illness.”
“After initially indicating that Aduhelm could be prescribed to anyone with dementia, the Food and Drug Administration now specifies that the prescription drug be given to individuals with mild cognitive impairment or early-stage Alzheimer’s, the groups in which the medication was studied.Yet this narrower recommendation raises questions. What does a diagnosis of mild cognitive impairment mean? Is Aduhelm appropriate for all people with mild cognitive impairment, or only some? And who should decide which patients qualify for treatment: dementia specialists or primary care physicians?”
#8. The Federal Trade Commission (FTC) hardens data security rules for health apps and devices:
“With data breaches on the rise, the FTC is looking to make health apps more accountable for telling patients when their data has been exposed.”
