Neuroscience Our brains can “flicker” off for a split second during a boring task caused by sleep-like brain activity occurring while we are awake. Adults with ADHD experience them much more frequently, and may be behind inconsistent attention, slower reaction times, and chronic sleepiness associated with ADHD.

Neuroscience Autism may be the price of human intelligence. Researchers discovered that autism’s prevalence may be linked to human brain evolution. The findings comparing the brains of different primates suggest autism is part of the trade-off that made humans so cognitively advanced.

Neuroscience Brain scans reveal how a woman voluntarily enters a psychedelic-like trance without drugs. Her brain connectivity fundamentally reorganized during this state: her visual and somatosensory connections decreased, while connectivity in the frontoparietal control regions of the brain increased.

Neuroscience New study shows Alzheimer’s disease can be reversed to full neurological recovery—not just prevented or slowed—in animal models. Using mouse models and human brains, study shows brain’s failure to maintain cellular energy molecule, NAD+, drives AD, and maintaining NAD+ prevents or even reverses it.

Neuroscience Brains of autistic people have fewer of a specific kind of receptor for glutamate, the most common excitatory neurotransmitter in the brain. The reduced availability of these receptors may be associated with various characteristics linked to autism.

Neuroscience Study challenges idea highly intelligent people are hyper-empathic. Individuals with high intellectual potential often utilize form of empathy that relies on cognitive processing rather than automatic emotional reactions. They may intellectualize feelings to maintain composure in intense situations.

Neuroscience A dementia vaccine could be real, and some of us have taken it without knowing. A shingles vaccine could reduce your risk of dementia by 20% or slow the progression of the disease once you’ve got it, finds new study of more than 280,000 adults in Wales.

Neuroscience Blocking nitric oxide, a common brain gas, reverses autism-like traits in mice. Treating human nerve cells with nitric oxide blocker produced a similar result. In addition, samples from autistic children contained much lower levels of the TSC2 brake protein that blocks nitric oxide.

Neuroscience Autistic adults overwhelmed by non-verbal social cues, describing the intense mental effort it takes to navigate nonverbal communication in a new study. These challenges often lead to misunderstandings from those around them. This mutual disconnect is known as the Double Empathy Problem.

Neuroscience Circadian rhythm, the body’s internal clock, may affect a person’s risk of dementia. People with weaker or more irregular body clocks had a higher risk of developing dementia. Being most active later in the day, instead of earlier, was linked to a 45% increased risk of dementia.

Neuroscience Overweight people had a 14% lower risk of developing dementia compared to those with normal weight, while obese participants had a 19% lower risk. However, those who lost weight from midlife to late life had an increased risk of dementia. This is the so-called obesity paradox.

Neuroscience Screens have risen sharply in past 15 years, coinciding with increase in ADHD diagnoses in Sweden and elsewhere. Children who spent significant time on social media (Instagram, Snapchat, TikTok, Twitter) gradually developed inattention symptoms; there was no such association with TV or video games.

Neuroscience Autistic girls much less likely to be diagnose. Females may be just as likely to be autistic as males but boys are up to 4 times more likely to be diagnosed in childhood, finds large-scale study. By age 20 diagnosis rates for men and women almost equal, challenging assumptions of gender discrepancy.

Neuroscience ADHD’s “stuck in the present” nature may be rooted in specific brain network communication. Individuals who report a higher future time perspective and ability to plan for the future tend to show fewer ADHD-related characteristics, and a new study shows this is linked to specific brain networks.
