2. Dyslexia Is Not a Neurological Disorder But an Evolutionary Survival Trait
People with dyslexia have strengths in experimentation, innovation, and searching for the unknown, all of which play a crucial role in how humans adapt and survive, according to a new study. The first study of dyslexia to use the “cognitive search” model, a cross-disciplinary approach with an evolutionary perspective, the study finds that the difficulty experienced by people with dyslexia results from a “cognitive trade off” between discovering new information and exploiting existing information.

3. Adderall Shortage Impacts Individuals with ADHD
The largest supplier of name brand and generic Adderall in the U.S. reports backorders of Adderall immediate-release tablets in 20mg and 30mg dosages, a shortage which has disrupted the treatment of people who rely on the prescription drug to manage their ADHD symptoms. The supplier, Teva, attributes the Adderall shortage to “supply disruptions” resulting in shipment delays; an additional factor is the increased demand for Adderall due to a surge in ADHD diagnoses during the pandemic from telehealth providers.

9. Maladaptive Daydreaming Should Be a Diagnosis Distinct from ADHD
Maladaptive daydreaming — the phenomenon of slipping into detailed, realistic, and long-lasting daydreams that can interfere with the ability to function — should be a diagnosis distinct from ADHD, according to this study published in Journal of Clinical Psychology. The study suggests that deficits in attention are often a side effect of maladaptive daydreaming, which is an independent mental phenomenon, rather than a part of ADHD.
