The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

New study identifies dopamine's role in reversing Alzheimer's

Imagine if patients with Alzheimer's could have their memories restored. Such a future may seem like a pipe dream, but a new study by researchers at Tohoku University, in collaboration with the University of California, Irvine, has identified dopamine dysfunction as a previously unrecognized mechanism underlying memory impairment, unlocking a potential therapeutic means of reversing cognitive decline.

Chia seeds may boost fetal brain DHA during obesity-linked pregnancy

Chia seed supplementation during pregnancy increased maternal omega-3 long-chain fatty acids, including DHA, in a rat model of high-fat-high-sugar diet-induced obesity. The findings suggest plant-derived ALA from chia seeds may improve maternal, placental, and mid-gestation fetal brain lipid profiles, but human relevance and offspring outcomes still need testing.

Aged immune cells may drive memory decline by releasing a brain-aging protein

A preclinical mouse study in Immunity suggests that aged circulating CD8+ T cells can disrupt hippocampal function and impair learning and memory. The findings point to granzyme K, a secreted factor linked to age-associated CD8+ T cells, as a potential target for restoring aspects of cognition in aging.

WHO warns of rising nicotine pouch addiction among youth

The World Health Organization (WHO) today issues a strong warning over the rapid global expansion of nicotine pouch products, which are being aggressively marketed to adolescents and young people.

Evidence shows RF-TC improves seizure control by altering brain networks

Drug-resistant epilepsy affects millions of people worldwide and remains one of the most difficult neurological disorders to treat. For patients whose seizures continue despite medication, surgical removal of seizure-causing tissue can be effective.

Psilocybin offers fast-acting alternative to traditional antidepressants

A single dose of the psychedelic substance psilocybin can provide rapid relief from depressive symptoms – within just a few days. This is shown by the first randomised, double-blind study in Sweden of psilocybin for depression. The effect persisted for over three months, according to researchers at Karolinska Institutet.

Rocket Science Health validates targeted olfactory-cleft deposition in non-human primates ahead of the 4th Nasal Formulation & Delivery Summit

As the pace of modern drug discovery accelerates, the industry is increasingly recognizing that a breakthrough molecule is only as effective as its ability to reach the target site.

Research identifies significant spike in neurological disorders during the covid-19 pandemic

In 2021, neurological diseases affected 3.40 billion individuals worldwide, corresponding to 43.1 % of the global population. In China, rapid demographic shifts and lifestyle changes have contributed to a continued rise in the burden of stroke, dementia, and Parkinson's disease-a trend expected to persist.

Stent-assisted coiling and flow diverters effectively treat rare basilar artery cases

Basilar trunk artery aneurysms (BTAs) are among the rarest and most complex types of brain aneurysms, occurring in a critical vessel that supplies blood to the brainstem. Because of their location and low incidence, there has been limited research guiding how best to treat them, leaving neurosurgeons with few large datasets to inform clinical decisions.

Healthy brain maintenance protects cognitive skills from early Alzheimer's effects

A healthy brain may help protect thinking and memory skills from the early effects of Alzheimer's disease, a new study has found.

Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.

The Goldilocks sleep zone: study links too little and too much sleep to biological aging

The Nature study introduces “Sleep Chart,” a framework linking self-reported sleep duration with 23 biological aging clocks derived from MRI, plasma proteomics, and metabolomics. Across UK Biobank participants, the lowest biological age gaps generally appeared between 6.4 and 7.8 hours of sleep, while shorter and longer sleep were associated with higher disease and mortality risk.

Brain immune cells found to regulate anxiety and grooming behaviors

A study led by a University of Louisville School of Medicine pediatrics and child neurology researcher reveals how a specific signaling mechanism in microglia, the brain's immune cell, can regulate anxiety and grooming behaviors. These behaviors are core symptoms of autism and obsessive-compulsive spectrum disorders.

Retinal stimulation via contact lenses effective as antidepressants in mice

Materials scientists have designed brain-stimulating contact lenses that are as effective as Prozac at treating depression in mice. The soft, transparent contact lenses have in-built electrodes that deliver mild electrical signals to the brain via the retina to stimulate specific brain regions associated with depression.

Identifying the methodology gap that prevents treatment of infection-triggered chronic diseases

Thousands of Americans develop chronic persistent symptoms-such as fatigue, cognitive difficulties ("brain fog"), and other debilitating issues-each year following acute infections from Lyme disease, COVID-19, and other pathogens. Efforts to identify causes and produce treatments have failed. However, 16 leading researchers think they know part of the problem: study design.

Scientists identify methylphenidate as an effective tool for combating chronic cancer-related fatigue

A new meta-analysis in the May 2026 issue of JNCCN-Journal of the National Comprehensive Cancer Network provides updated evidence that methylphenidate-type psychostimulants-a class of medication that increases dopamine and norepinephrine availability in the brain-can provide meaningful relief for cancer-related fatigue.

Study reveals how brain cells process vision amidst thousands of synaptic inputs

Even in the primary visual cortex, a brain region named for its specialized role in processing basic features of what the eyes see, not every neuron ends up answering the call to process properties of visual input. Maybe that's because each neuron receives a wide variety of inputs via thousands of circuit connections, or "synapses," and has to opt to respond to the visual information vs. something else.

A comprehensive longitudinal study reveals dreams are shaped by personality

A study that analyzed, over four years, thousands of reports of dreams and waking experiences reports that what we dream is shaped by stable individual traits, such as attitudes toward dreaming, the tendency for mind-wandering, and subjective sleep quality.

New research maps the biological toll of drinking

A new review published in the journal Addiction confirms drinking causes substantial harm to health. Some of those harms may be reversible if the person reduces or stops drinking.

Study warns of rising cognitive impairment following a heart attack

The chance of developing cognitive impairment was significantly higher for people who have had a heart attack, according to a study published today in Stroke, the peer-reviewed scientific journal of the American Stroke Association, a division of the American Heart Association.
