MS Drugs reduce inflammation, helping reduce relapses and slow disease progression

GLP-1s may lower inflammation, possibly helping to combat cognitive decline

An analysis of existing GLP-1 research, published in April 2025, indicated that GLP-1 drugs reduce inflammation, with numerous health benefits. The work notes that GLP-1s were linked with a statistically significant reduction in dementia in randomized clinical trials.

HRT for menopause may not help with mental health or sleep says a large 2026 analysis

A recent analysis investigating the effects of menopause and HRT use on mental health, cognition, and brain health suggested HRT did little or nothing to aid with mental health and sleep. But the researchers caution that, among other data gaps, they didn't have information on which HRT formulations were used among their nearly 125,000 participants, so results may have varied by drug treatment.

Scientists are reevaluating the causes of Alzheimer's beyond the amyloid hypothesis

The cause of Alzheimer's disease has been debated for decades. The amyloid cascade hypothesis—where plaques build up in the brain, triggering neurodegeneration—has long been the leading theory. But after a number of failed drug trials, researchers are beginning to reevaluate various culprits. [Untreated hearing loss is linked with dementia risk](https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext) Hearing loss does not cause dementia, but it does increase the risk of developing dementia and research suggests that people who wear hearing aids for age-related hearing loss also maintain better brain function than those who don't.

How supplements and alternative medicine are being used to treat MS

MS patients often use complementary and alternative medicine approaches for MS, including acupuncture, yoga, specific diets, herbs like turmeric, and cannabis. Information on integrative approaches often come from support groups and online communities. Complementary care is typically used in conjunction with traditional medicines.

How reading and writing can lower dementia risk by almost 40%

Research published in 2026 that tracked almost 2,000 older adults for an average of nearly eight years suggests that lifelong exposure to intellectual stimulation, such as learning a language, reading, and writing, can lower dementia risk by as much as 40%.

Menopause hormone therapy infuses the body with estrogen after the body's natural levels drop

The treatments can treat symptoms like hot flashes and vaginal dryness at varying doses. Progestogen, another hormone, is also typically prescribed with estrogen because estrogen alone can thicken the uterus lining, which elevates the risk of developing endometrial cancer.

Menopause affects the brain in complex ways

Lisa Mosconi, a neuroscientist studying the impact of menopause on the brain, explains in this video how menopause directly impacts a woman's brain health and explores why this is an important and often overlooked area in menopause and women's aging healthcare discussions.

MS risk is shaped by geography, not just genes

Latitude—and related vitamin D exposure—seems to affect MS risk. People who migrate from a high-risk MS latitude (like northern Europe or the northern US) to a lower-risk latitude (like tropical areas) before age 15 tend to adopt the lower risk of their new country—suggesting there's a critical window for environmental exposure.

Remylination is a huge focus for treatment—especially among older adults

Our ability to build new myelin sheaths for nerves degrades with age. There have been research advances boosting cells that support these processes and clear away debris from degraded myelin, but not yet any medications to boost myelination itself, which would aid nerve signaling and preserve nerve function.

Cigarette smoke exposure boosts MS risk by up to 55%, though smokeless tobacco doesn't

The components of the smoke itself are associated with these significantly increased risks, so it's something beyond nicotine itself that drives that risk. What's more, smoking also increases the risk of developing antibodies to MS-treating drugs.

How one autoimmune disease patient is questing for inflammation cures

This article's writer, who has Hashimoto's Disease and characteristic symptoms from her body attacking her thyroid—like exhaustion, hair loss, and brain fog—shares big take-aways from an anti-inflammatory retreat in Italy. The writer suggests that a holistic approach to eating, sleeping, and stress management, are the only sustainable ways to lower inflammation.

Can microdosing improve mental health?

Animal studies involving microdoses of psilocybin, the psychoactive component in magic mushrooms and ketamine, found it helped to alleviate anxiety and inflammation, an immune response that can cause damage when chronically active. Human studies are ongoing. In at least one double-blind study, where researchers and patients don't know who got a placebo versus the real thing, about half of the participants incorrectly guessed they had been given placebos.

Alzheimer's can lead to brain shrinkage, with an average of around 2% of volume reduction per year

Chronic drug use can cause neurological changes in the brain

Neuroscientist Judy Grisel breaks down the biology of addiction, examining how drugs hijack the brain’s natural reward system and create lasting neural changes. The physiological and neurological impacts of chronic drug use require a multifaceted treatment approach.

Can humans delay or reverse old age?

We're not sure yet. Researchers at the University of California San Francisco are studying why some conditions and behaviors, such as low-oxygen environments and exercise, benefit the aging process, hoping to reveal potential health applications. Some of this research focuses on klotho, a naturally occurring age-regulating hormone named after the Greek Fate Clotho. Animal studies on klotho brain injections found subjects had improved memory recall and age-related degeneration resistance.

Females are diagnosed with MS roughly 3 to 4 times more often than males

This PBS documentary traces a filmmaker's personal journey with MS after being diagnosed at age 26. It encompasses both his efforts to stymie the disease's progression and his search for answers about the disease, when, statistically, he seemed at low risk due to his gender, lack of known family risk, and other factors.

A vaccine against Epstein-Barr virus, researchers hypothesize, could potentially prevent MS

As many as a quarter of MS patients have antibodies in their blood that bind to both a central protein in Epstein-Barr virus and a protein made in the brain and spinal cord that—when attacked—leads to a breakdown of protective nerve fiber insulation. This suggests the immune system's primed to attack the nervous system after mounting a defense against Epstein-Barr.

Vitamins can slow macular degeneration

Research published in 2022 affirmed that vitamin formulations containing vitamins C and E, copper, zinc, lutein, and zeaxanthin—but no beta carotene—can enhance eye health and slow the progression of macular degeneration.

Certain medications that affect blood flow or mood boost the risk of heatstroke

Drugs that narrow blood vessels, beta blockers that regulate blood pressure, diuretics, antidepressants, and antipsychotics can all affect the body's ability to regulate its internal body temperature, and so individuals taking these medications need to take special care in extreme heat and when exercising in hot conditions.

A new daily MS pill is seeking regulatory approval in 2026

In clinical trials, Roche's fenebrutinib showed promise treating primary progressive MS and doubling relapse-free time in patients with relapsing MS as compared to existing treatment. But some liver damage and two possible drug-related deaths in the trials may make it difficult for the drug to net approval. (Some users may encounter a paywall.)

Women typically have more robust immune responses than men

This difference helps women better combat infectious diseases, but this more turbo-charged response may also make women more vulnerable to autoimmune diseases by potentially priming their immune systems to overreact to their own cells and tissues and label them as invaders that must be destroyed. Roughly 80% of American women have autoimmune conditions.

Changes in vision or eye pain can be early MS symptoms

This occurs due to myelin degradation around the optic nerve, impairing its ability to transmit visual information to the brain. Individuals may especially experience eye symptoms after exercising or taking a hot shower because boosted body temperatures slow down nerve function in nerves already damaged by MS.

Resistance training can help fight osteoporosis, especially in menopausal women

Weight-bearing training that pulls on bones, joints, and muscles can strengthen bone health. Movements like squats, rows, shoulder and chest presses, and push-ups can be started at any age (if you don't already have advanced bone loss), though ideally they should be started earlier—in one's teens or young adulthood—to stave off bone density losses that begin in your 30s.

New drugs called Gepants have been shown to improve the quality of life of many sufferers.

Journalist Eva Wiseman has had migraines since childhood. Beginning with a yawn they segue into visual auras before turning into severe pain. As it so happened, she experienced a migraine during the course of her interview with Dr. Peter Goadsby, a pioneer in understanding and treating migraines as well as getting the world to treat them seriously.

Exercise changes your genes without changing your DNA

Physical activity can turn beneficial genes on and harmful genes off, without altering the underlying DNA code. This engaging article explains the epigenetic mechanisms that take place with exercise and ultimately result in improved metabolism, lower inflammation, and optimized brain function.
