good point. It could be a combination of their inherited TLR4 variants -- as well as whether TLR4 is involved in ME/CFS for that patient.

Not everyone with PCOS has ovarian cysts, and not everyone with ovarian cysts has PCOS. PCOS affects about 5 to 18% of premenopausal women and is estimated to be around 70% heritable. There isn't one PCOS gene, though. The research points to four overlapping pathways, which are hormone dysregulation, insulin resistance, circadian disruption and inflammation. The insulin piece runs both ways. Insulin pushes the ovaries to make more testosterone, and giving women testosterone increases insulin resistance. The circadian piece is the one I find most interesting. In animal studies, disrupting the body clock with light caused the same hormone changes seen in PCOS. So late nights under bright lights may matter more than most people think. Knowing which pathway is driving yours helps you decide what to work on first. 👇 geneticlifehacks.com/genetic…

It's good to see more clinical trials using repurposed drugs for Alzheimer's. It's interesting, though that they chose metformin and atomoxetine. Here's a prior phase II trial on Atomoxetine that showed no cognitive benefits in 12 months. Small trial, though, so maybe a larger one will show statistically significant changes. pmc.ncbi.nlm.nih.gov/article…
Diabetes and ADHD drugs to be tested on Alzheimer's patients in new study | Fergus Walsh, BBC A clinical trial has been launched in the UK which scientists hope could cut years from the search for new treatments for Alzheimer's disease. It will test multiple drugs simultaneously, starting with two repurposed medicines already used to treat type 2 diabetes and attention deficit hyperactivity disorder (ADHD). The study will examine whether the drugs can lessen symptoms such as memory and thinking problems, and help people maintain their quality of life. Angela Bucksey, 67, from Cambridgeshire, was diagnosed with Alzheimer's in January and is the first person to begin treatment on the trial, called AD-SMART. "We have Alzheimer's in the family," she told the BBC. "My mother had it and my aunts, so it was a disappointment rather than a shock when I was diagnosed because I knew it would restrict my life. "But I was determined that it wasn't going to define me." Angela said she felt empowered joining the trial because "at least you are doing something". "Instead of just sitting there, you're standing up and saying, I will fight back." Alzheimer's is the most common type of dementia, affecting around 600,000 people in the UK. 'Cutting-edge treatments' Prime Minister Andy Burnham, whose father died from Alzheimer's last month, said he knew how it felt to lose a loved one to dementia, and had seen first-hand the devastating impact of the disease on families. "That's why I'm proud to see this trial being launched in the UK, so that cutting-edge treatments can reach patients here as soon as possible," he said. The AD-SMART study is what's known as a multi-arm, multi-stage platform trial where several treatments are tested simultaneously, with the results compared with one group of participants taking a placebo or dummy. This means those involved have a higher likelihood of getting an active treatment than in a traditional trial. If any drug isn't showing benefit it can be dropped quickly and a new treatment added in its place - the approach has been used successfully in cancer and motor neurone disease. The two initial drugs being tested are metformin, used to treat type 2 diabetes, and atomoxetine, for ADHD, which were selected by an international panel of experts. Both drugs may help reduce brain inflammation, which is a driver of neurodegeneration, said chief investigator Prof Paresh Malhotra, group leader at the UK Dementia Research Institute Centre for Care Research & Technology at Imperial College London. "For too long, Alzheimer's research has moved at the pace of one drug, one trial, one answer - sometimes taking a decade or more before we know if we've found something that works," he told the BBC. "We are applying advances from cancer and other conditions to accelerate testing of treatments for people with Alzheimer's disease." 'Back from despair' For the drugs to be successful, the study has to show that they have beneficial effects on thinking and the ability to carry out everyday activities. "That's what patients and their carers care about," said Prof Malhotra. Some 1,200 participants with mild to moderate Alzheimer's will be recruited at more than 30 sites across the UK. Sites in Cambridgeshire, Surrey, London, Southampton and Edinburgh are already open. Scientists expect to finish evaluating the first drugs in 2030 and, in that time, additional treatments are likely to be added. All the participants will have regular health checks including cognitive tests, which will help researchers assess how effective the treatments are. Angela Bucksey's husband Steve, who is her study partner, told the BBC: "Joining the trial has brought us back from the despair of a diagnosis which everybody recognises is non-recoverable. "People who know we are on a drug trial understand that we're doing something about it and, rather than be sorry for us, they can be encouraging." Dr Sheona Scales, director of research at Alzheimer's Research UK said "time is precious" for people living with Alzheimer's disease and more treatment options are urgently needed.

Interesting saffron study in perimenopause. The mood and anxiety improvements fit with older research, where saffron seems to act on serotonin and also has anti-inflammatory effects. The caveats in this thread are worth reading though. It's industry funded, not peer reviewed yet, and the effect is double the earlier trial. Still, there aren't a lot of drawbacks to trying saffron. Here's more research studies on saffron: geneticlifehacks.com/saffron…
A saffron extract cut perimenopausal symptom scores by 68% in 12 weeks versus 17% on placebo, roughly twice the benefit a similar saffron trial reported five years ago. Saffron’s most consistent evidence is for mood, and a 2019 meta-analysis of 23 trials found large effects on depressive and anxiety symptoms compared with placebo, although it also found signs of publication bias and little regional diversity. In menopause, a 6-week trial in postmenopausal women with depression and hot flashes reported improvements in both. The closest comparison is a 2021 Australian trial in 86 perimenopausal women, where a different extract at 28 mg a day lowered total symptom scores by 32% versus 14% on placebo, with clear gains in anxiety and depression but nothing beyond placebo for hot flushes or physical symptoms. Those studies left the size of saffron’s effect across perimenopause uncertain. In the new preprint, 104 women in perimenopause at three sites in Pakistan were randomized, double-blind, to 30 mg a day of a standardized extract or placebo for 12 weeks, with symptoms rated on the 21-item Greene Climacteric Scale. 1. Total scores fell from 35.2 to 11.2 on saffron and from 35.6 to 29.4 on placebo, and most of the saffron effect had appeared by week 6, when scores were down 44% versus 10%. 2. Psychological symptoms fell 67% versus 16%, and physical symptoms such as headaches, aches and dizziness fell 75% versus 18%, while the combined hot flush and night sweat score narrowly missed significance even though night sweats improved. 3. Mood scores, rated sleep quality, several quality-of-life measures and triglycerides also improved, and mild side effects were similar in both groups (10 versus 8 events). Taken together, the direction matches earlier saffron research, especially for mood, but the size does not. Placebo groups improved by similar amounts in both perimenopause trials (14% and 17%), while the saffron effect more than doubled, from a 32% drop to a 68% drop. For women whose perimenopause is dominated by anxiety, low mood and low energy, saffron is a reasonable option to discuss, but the 68% figure should be treated as a ceiling until an independent group repeats it. This is a preprint that has not been peer reviewed, the extract’s maker funded the trial, and four authors work for the company. Only 63 of 104 women fully followed the protocol, and several smaller results faded when the analysis was limited to them. The paper reports that hot flushes improved no more than on placebo, yet its own table shows scores falling from 2.0 to 0.6 on saffron versus 2.0 to 1.5 on placebo, an inconsistency the authors need to resolve. Women using hormone therapy, antidepressants or sleep medication were excluded.

This one is likely to be disappointing for a lot of people who feel LDN helps them. A placebo-controlled trial in post-COVID ME/CFS found no real difference in fatigue or pain. one thought, though. LDN is thought to work partly by calming TLR4 signaling in microglia, and people vary a lot in opioid receptor and TLR4 genetics. Average results can hide a subgroup (with genetic variants) that responds. Has LDN helped you, or did it do nothing?
1) 🇨🇦 The results of Luis Nacul's trial of low-dose naltrexone (LDN) have been published. Unfortunately, it shows that LDN didn't improve fatigue, pain and other symptoms in patients who developed ME/CFS after COVID-19. A brief breakdown of the main results. 👇

This is one of my favorite aging studies - from a couple of years ago, I think. IL-11 is an inflammatory signal that climbs with age, and blocking it in older mice extended median lifespan by about 25% in both males and females. The treated mice also had less frailty, better metabolism, and fewer cancers. IL-11 seems to drive aging partly by keeping mTOR switched on, the same growth pathway rapamycin targets. Mouse study, and the antibody isn't available for people... But there are some ways to impact IL-11 that I wrote about here: longevitylifehacks.substack.…
These two mice are the exact same age, the human equivalent of 85. The mouse on the right was given an antibody blocking a single inflammatory protein (IL-11) starting in late middle age. Starting treatment at human-equivalent age 55: - Extended median lifespan by 25% in both males and females - Prevented grey hair, frailty, and muscle wasting - Cut late-life cancer deaths in half Three anti IL-11 antibodies (that might extend human lifespan) are already in human clinical trials right now.

Interesting study. Creatine plus lifting twice a week, and perimenopausal women had more regular sleep and fewer days of feeling overheated or hot flashes. There's actually a neat hormone link here. The brain uses creatine to recycle ATP through an enzyme made by the CKB gene, and CKB was originally discovered as a protein that estrogen switches on. So when estrogen drops, brain energy can be affected.
Creatine may help women in perimenopause maintain more consistent sleep when combined with strength training. Women taking creatine for 6 weeks had sleep regularity scores 7.4 percentage points higher than the placebo group, reported fewer days of temperature sensitivity, and had greater brain oxygenation during a cognitive task. The protocol was 20 grams of creatine monohydrate daily for 5 days, followed by about 4.5 grams daily, with resistance training twice a week. These are encouraging early findings, particularly for sleep regularity in a population known to suffer from poor sleep quality! I love seeing more creatine research in women. pubmed.ncbi.nlm.nih.gov/4292…

A new study in Cell found that taurine levels don’t drop with age (the way they measured them). Yet supplementing with taurine was still beneficial in aging mice. The mechanism is interesting. Taurine helped to prevent excess NLRP3 activation - preventing inflammaging, of this sort. Here’s my latest Longevity Lifehacks article on it. longevitylifehacks.substack.…

T cells can get worn out. Researchers call it T cell exhaustion, and most of the early work came from HIV and hepatitis C patients in the 90s. When a T cell keeps seeing the same antigen for too long, it turns up brakes like PD-1, TIM3, CTLA-4 and LAG-3 and stops responding well. In mice, 1 to 2 weeks of antigen made healthy memory T cells, while 2 to 4 weeks pushed them toward exhaustion. It works more like a dimmer switch than an off switch. A portion of long Covid patients show this pattern, and a 2024 study found it was common in ME/CFS. In one study, when treatment improved CD8+ T cell function, symptom severity dropped by more than half. By 24 months, many long Covid patients had T cells that looked more normal again, along with better quality of life. Exhausted T cells also tend to have struggling mitochondria. Genetic variants shift how easily you hit that threshold. 👇 geneticlifehacks.com/t-cell-…

Histamine dark circles is one of the real ones on this list. Allergic shiners come from congestion and dilated blood vessels under the eyes, and they show up a lot in people with allergies and mast cell issues. However, this doesn't mean it's always histamine... Thin under-eye skin (often in aging) and plain old genetics can do it too.

Good video for POTS Awareness Day. Something I wish more people knew is how often POTS coexists with other things, like hEDS, mast cell issues, ME/CFS, and long Covid. A big share of long Covid patients end up with some form of dysautonomia. More on the background science and genes that increase susceptibility here: geneticlifehacks.com/genetic…
In honor of POTS Awareness Day, I wanted to share a video that I genuinely wish more people would take the time to watch. It’s one of the best videos I’ve come across explaining what POTS actually is and just how debilitating living with this condition can be.

Exercise helped people with depression who had not responded to SSRIs, but only in a study where they stuck with it for 12 weeks. The participants had high TNF alpha or IL-1 beta at baseline and did aerobic exercise like treadmill or cycling. Their depression scores kept improving through the full three months, so this was not an instant mood lift. The biology lines up. TNF alpha and IL-1 can increase serotonin reuptake and IL-1 beta can lower neurogenesis through the kynurenine pathway. If you carry TNF or IL1B variants, steady aerobic exercise may be a stronger lever than it looks on paper. geneticlifehacks.com/is-infl…

Doctors learned inflammation could change mood by accident in the 1980s. Interferon alpha was used for chronic hepatitis, and some people on the highest doses quickly developed depression, agitation, emotional swings and even paranoia. Lowering the dose made the psychiatric side effects go away. That history still explains sickness behavior today. When you fight a virus you get tired, irritable and want to be left alone, which is a useful short term response. The problem is when those same signals stay on for months. TNF and IL6 variants are part of why some people seem more sensitive to that shift. 👇 geneticlifehacks.com/is-infl…

Fibromyalgia pain is not just tender points, and doctors do not even count those 18 spots the old way anymore. Current thinking points to a mix of low grade neuroinflammation, central pain amplification and mitochondrial energy problems. Biopsies have found more mast cells right in painful areas, and studies link pain intensity to TNF alpha and IL-8 even when average levels look normal. That overlap helps explain why fibromyalgia often travels with IBS, migraines, POTS and ME/CFS. Sorting out which driver fits you matters more than collecting another generic pain tip. Has one angle explained your pattern better than the others? 👇 geneticlifehacks.com/fibromy…

This is interesting and will be watching for the results on it in 2027. Wilson disease comes from mutations in ATP7B,which moves extra copper out of the liver and into bile. This trial targets the most common mutation in people of European ancestry, with about 1 in 90 people carrying one copy. Carriers don't get Wilson disease, but some studies show slightly lower ceruloplasmin indicating that copper may be higher than normal. geneticlifehacks.com/wilsons…
BREAKING: Scientists have used a powerful new form of CRISPR called prime editing directly inside the human body for the first time. They aim to rewrite faulty DNA responsible for Wilson disease that can cause severe liver and brain damage. A major milestone in gene editing.

Agree that every woman is different, and genetics is a big part of that when it comes to risks and effects of HRT. COMT and CYP1B1 variants change how estrogen gets broken down, and Factor V Leiden matters a lot for clot risk on oral estrogen.

Two big blood clot stories this week, w/ Jalen Hurts at age 28 and Ric Flair. Long flights and leg injuries are classic triggers, but genetics matters too when it comes to susceptibility. Factor V Leiden (F5 rs6025) is carried by about 3-8% of people of European ancestry and raises DVT risk roughly 4-fold. Most carriers never end up with a serious DVT, but it's worth knowing before surgery, long-haul plane rides, or estrogen hrt. Prothrombin variants can also increase the clotting risk.
I Want To Sincerely Apologize To My Agent, Steve Solomon, Washington State Horror Con @wahorrorcon, @bigeventny, And Especially All My Fans In Seattle For Having To Cancel My Scheduled Appearance. Unfortunately, I Am Dealing With A Blood Clot In My Leg, And My Doctors Have Limited My Travel To 3–4 Hours. Seattle Falls Outside That Range, And As Disappointed As I Am, I Have To Put My Health And Recovery First. Blood Clots Are Extremely Serious And Can Be Life-Threatening. We Have Seen This Recently With Jalen Hurts And The Complications Involving Blood Clots In His Lungs. It Is A Reminder That This Is Not Something To Take Lightly, And I Must Follow Medical Advice. I’m Scheduled To Have A Procedure To Strip The Affected Vein, Which My Doctors Expect Will Allow Me To Be Cleared For More Travel Afterward. Please Know This Decision Was Not Made Lightly. I Am Truly Sorry For The Inconvenience And Disappointment, And I Am Incredibly Grateful For Your Patience, Understanding, And Continued Support. I Look Forward To Getting Healthy And Seeing You All Down The Road. Thank You For The Love And Support. Much Love,
Ric Flair

This is cool, although it's important to note that it is in mice... The glymphatic system runs mostly during deep slow-wave sleep, and it depends on a water channel called aquaporin-4 (AQP4) on astrocytes. In older adults, AQP4 gene variants changed how strongly poor sleep tracked with amyloid buildup. But until this is tested in people, protecting and promoting deep sleep is still the best glymphatic clearance promoting option
Scientists found a way to flush Alzheimer’s plaque out of the brain in minutes. Without any surgery and drugs. Your brain has a waste-clearance network called the glymphatic system. It flushes out toxic proteins and dead cells. But it only really activates during deep, slow-wave sleep. If you don't sleep, the trash piles up. Over time, that buildup leads to cognitive decline and Alzheimer's. Until today. Researchers just published a paper proving they can manually trigger this cleaning cycle. Without you ever going to sleep. They used 40.68 MHz ultrashort waves (USW) beamed non-invasively into the brain. Within 10 minutes, the brain's fluid flow rapidly accelerated. The waves artificially synchronized the neurons into a Delta state, the exact frequency of deep sleep. This forced the brain's water channels to open and start flushing out the system. They tested it on mice with traumatic brain injuries and Alzheimer's pathology. The brain swelling dropped. The toxic proteins were cleared out. Cognitive deficits actually improved. No surgery. No massive chemical interventions. Just a frequency.
