Digital technology use linked to lower risk of cognitive decline

As the first generation that interacted with digital technology reaches an age where dementia risks emerge, scientists have asked the question: Is there a correlation between digital technology use and an increased risk of dementia?

EAT-Lancet planetary diet shows no dementia risk, may protect against Alzheimer’s

In a large Swedish study, researchers found that the environmentally sustainable EAT-Lancet diet does not increase dementia risk and may lower the risk of Alzheimer’s and all-cause dementia, particularly in people without the APOE ε4 gene. The findings support the integration of sustainable diets into dementia prevention strategies.

Cannabis use linked to increased dementia risk after emergency care

Individuals with an emergency department (ED) visit or hospitalization due to cannabis were at 23% and 72% greater risk of a new dementia diagnosis within five years compared to individuals with an ED visit or hospitalization for any other reason or the general population, according to a new study published in JAMA Neurology.

Scientists identify critical enzymes for astrocytic GABA production in Alzheimer’s disease

A research team at the Institute for Basic Science (IBS) has identified a previously unknown enzyme, SIRT2, that plays a key role in memory loss associated with Alzheimer's disease (AD).

Eating more potassium-rich foods may be effective for lowering blood pressure

New research from the University of Waterloo suggests increasing the ratio of dietary potassium to sodium intake may be more effective for lowering blood pressure than simply reducing sodium intake.

What really causes keto flu, and how can you prevent it?

A scoping review from the University of Bergen identifies a wide range of transient symptoms—collectively known as "keto flu"—that occur during the initiation of a ketogenic diet. The review explores their physiological basis and highlights strategies, such as MCTs and electrolyte supplementation, to ease the transition.

Northwestern scientists identify key genes behind Parkinson's development

A longstanding mystery in Parkinson's disease research has been why some individuals carrying pathogenic variants that increase their risk of PD go on to develop the disease, while others who also carry such variants do not.

Sleep enhances memory for life events over the long term

While sleep's positive impact on cognition has long been recognized, Baycrest researchers have revealed that a good night's sleep may actively enhance memory rather than simply protect it from decline.

Heavy drinking linked to increased risk of brain lesions

Heavy drinkers who have eight or more alcoholic drinks per week have an increased risk of brain lesions called hyaline arteriolosclerosis, signs of brain injury that are associated with memory and thinking problems, according to a study published on April 9, 2025, online in Neurology®, the medical journal of the American Academy of Neurology.

Study explores impact of parental Alzheimer’s on tau protein spread in the brain

While some studies have suggested that having a mother with Alzheimer's disease may put you more at risk of developing the disease, a new study finds that having a father with the disease may be tied to a greater spread of the tau protein in the brain that is a sign of the disease, according to a study published on April 9, 2025, online in Neurology®, the medical journal of the American Academy of Neurology.

Protein linked to Parkinson's also found to drive melanoma growth

A small protein involved in neurodegeneration leading to Parkinson's disease also drives a type of skin cancer known as melanoma, new research led by Oregon Health & Science University finds.

Eating ultra-processed foods may rewire your brain’s hunger and reward circuits

High intake of ultra-processed foods is linked to adverse metabolic health and microstructural brain changes in regions that control appetite and reward. These effects occur both through obesity-related pathways and independently via inflammation and dyslipidemia.

Tim-3 identified as promising therapeutic target for Alzheimer's disease

Tim-3 is an immune checkpoint molecule involved in immunity and inflammation recently linked to late-onset Alzheimer's disease (AD), but its role in the brain was unknown until now.

Neural organoids offer insight into mechanisms of dementia

Researchers at The Ohio State University Wexner Medical Center and College of Medicine have discovered a new way that neurons act in neurodegeneration by using human neural organoids – also known as "mini-brain" models – from patients with frontotemporal lobar degeneration (FTLD).

Breakthrough nanoparticle delivery method targets brain inflammation for multiple conditions

Oregon State University researchers have discovered a way to get anti-inflammatory medicine across the blood-brain barrier, opening the door to potential new therapies for a range of conditions, including Alzheimer's disease, multiple sclerosis, Parkinson's disease and cancer cachexia.

Experimental drug NU-9 shows promise for Alzheimer's and ALS treatment

Experimental drug NU-9 - a small molecule compound approved by the U.S. Food and Drug Administration (FDA) for clinical trials for the treatment of amyotrophic lateral sclerosis (ALS) - improves neuron health in animal models of Alzheimer's disease, according to a new Northwestern University study.
