Cognition is a concept used in different ways by different disciplines, but is generally accepted to mean the process of thought. For example, in psychology and cognitive science it refers to an information processing view of an individual's psychological functions.

Restoring brain energy balance reverses advanced Alzheimer’s disease in mouse models

For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery.

Simple drug treatments could help older brains cope with memory decline and postoperative recovery

Simple pharmaceutical interventions could help older brains cope with memory impairment and recovery after surgery, new studies in mice suggest.

Two isoforms of a cellular energy sensor play distinct, opposing roles in Alzheimer's disease

A comprehensive mini-review published today after peer review in Brain Medicine by Dr. Tao Ma and colleagues at Wake Forest University School of Medicine synthesizes emerging evidence that two isoforms of a critical cellular energy sensor play distinct, and sometimes opposing, roles in Alzheimer's disease.

Integrated neural probes reveal dopaminergic control of sleep-wake transitions

Understanding the dynamic neural mechanisms of sleep-wake cycles is a major challenge in sleep science and neuroengineering.

Understanding sevoflurane-induced neurogenesis inhibition and cognitive dysfunction in children

Every year, millions of infants and children undergo surgery under general anesthesia in the world. Sevoflurane is a commonly used pediatric anesthetic. Its exposure during brain development has been shown to inhibit neurogenesis and cause cognitive dysfunction in animal models.

Targeting CSE enzyme may offer new pathways for Alzheimer’s treatment

Scientists at Johns Hopkins Medicine say results of a new National Institutes of Health-funded study are advancing efforts to exploit a new target for Alzheimer's disease: a protein that manufactures an important gas in the brain.

Restoring brain energy balance reverses Alzheimer’s disease in mouse models

For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery.

Unlocking sleep-wake secrets with dual brain signal analysis

Understanding the dynamic neural mechanisms of sleep-wake cycles is a major challenge in sleep science and neuroengineering.

Everyday light exposure shapes how alert and mentally sharp we feel outside the lab

This real-world study shows that recent and habitual light exposure are linked to lower subjective sleepiness and faster reaction times in daily life. Brighter and more stable daytime light patterns were associated with better performance on specific cognitive tasks, independent of sleep and time of day.

Social isolation emerges as a key, independent risk factor for cognitive decline

Using longitudinal data from the US Health and Retirement Study, this study applied causal inference modeling to disentangle the independent and joint effects of social isolation and loneliness on later-life cognitive function. It shows that reducing social isolation is associated with modest but meaningful protection against cognitive decline, with loneliness mediating only a small proportion of this effect.

Lysophosphatidylcholines show gene-dependent effects in early Alzheimer’s disease

A new study presents robust evidence on the role of lysophosphatidylcholines (LPCs) in the onset of Alzheimer's disease. Researchers discovered that LPCs-compounds that transport a variety of healthy fatty acids to the brain-either promote Alzheimer's or protect against it, depending on a person's genetics.

Brief light-intensity exercise improves executive function and mood in children

In modern society, physical inactivity and sedentary behavior have become common issues globally. This trend is also growing among children, raising concerns for their mental and physical health.

Combined physical frailty and depression may sharply raise dementia risk

Concurrent physical frailty and depression likely boost the risk of dementia in older people, with the interaction of these 2 factors alone contributing around 17% of the overall risk, suggest the findings of a large international study, published in the open access journal General Psychiatry.

New research highlights the importance of social engagement for cognitive health

New research from the University of St Andrews has discovered a direct causal effect between social isolation and a faster decline in later- life cognitive function. Pathological cognitive decline is most often driven by Alzheimer's and related dementias.

Study identifies a distinctive, measurable pattern of brain activity in children with ADHD

A new study suggests that children with ADHD may exhibit a distinctive, measurable pattern of brain activity that could reflect differences in neural efficiency.

Acupuncture improves breast cancer survivors' perceived cognitive impairment

Real and sham acupuncture were more effective at improving breast cancer survivors' perceived cognitive impairment compared with usual care, while real acupuncture was superior to sham acupuncture in improving objective cognitive function, according to results from the randomized ENHANCE phase II clinical trial presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9-12, 2025.

Blinking suppression reveals how the brain filters speech in noisy environments

Blinking is a human reflex most often performed without thinking, like breathing. Although research on blinking is usually related to vision, a new Concordia study examines how blinking is connected to cognitive function such as filtering out background noise to focus on what someone is trying to say to us in a crowded room.
