Reply to comment by Cherabee in Chinese researchers have reported what they claim is the world’s youngest person diagnosed with Alzheimer’s disease, which may overturn the conventional perception that cognitive impairment rarely occurs in young people. by Wagamaga

People do them and most go to clinics out of the country. They may have anti inflammatory properties that reduce symptoms to some degree temporarily. The risk is high and published evidence is lacking.

Reply to comment by tornpentacle in New analysis of 142 influential films featuring artificial intelligence (AI) — from 1920 to 2020 — reveals that nine (8%) of 116 AI professionals were portrayed as women by marketrent

I am sure that there were a few, especially compared to now. But I highly doubt that anyone in the 1920s was like wow there is 1 female scientist in the entire state, I need to make sure when I have this future movie I show women as the lead scientist. Maybe starting 40s-50s it was much more common (again compared to the 1920s, but still minuscule vs now)

Reply to comment by williamwchuang in A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga

"Herd immunity (also called herd effect, community immunity, population immunity, or mass immunity) is a form of indirect protection that applies only to contagious diseases. It occurs when a sufficient percentage of a population has become immune to an infection, whether through previous infections or vaccination, thereby reducing the likelihood of infection for individuals who lack immunity." -Wikipedia

Show me a covid-19 vaccine that can make me immune to infection. If a product doesn't provide that level of protection it can never be used to achieve herd immunity.

For Covid, infection-generated immunity wanes over time just as vaccine-induced immunity does. Regardless of what taught a person's immune system to recognize and fight SARS-CoV-2, it doesn't last. This has not only been documented from many data sources from many countries (ex nejm.org/doi/full/10.1056/NEJMoa2118946 ) it's also apparent in anyone's personal life. I think at this point we all know someone who's gotten covid multiple times.

It's also clear that avoiding infection is important not just to avoid death, but to avoid the negative health effects of multiple bouts of covid. nature.com/articles/s41591-022-02051-3

If I am reading the title of this thread right, the existence of a *single* young individual with alzheimers is about to "overturn" the idea that alzheimers is "rare" in young people?

Am I supposed to take this article seriously?

Excess mortality is a great measure but I don’t think the authors adequately show their methodology accounts for confounding variables. Not taking into account clinical characteristics (yes, I know it is difficult to link data in the US) is a major limitation. Figure 1 also reports a correlation of 0.97, but visually it does not look close to that. The bottom left is clustered with data points and the top right is pulling the correlation towards 1, so the methodology may also have limitations. I was surprised the authors did not address this.

Regardless, it still explores excess mortality and vaccination status, which is quite interesting

I'd have to look for it. But I do vaguely remember that vaccines were at least considered as treatment for it. No idea what came out of that.

I think everyone can agree that the elderly 60 and older should get a scheduled treatment of the vaccine until more data can come from the other age groups.

Agreed. Another big question is the comparable impact of vaccine immunity alone reducing transmission, compared to natural immunity from previous exposure. Nearly everyone has been exposed at this point, vaccinated or not. And we don’t have a very effective means at identifying a control group.

Reply to Investigators assessed the risk of dementia using changes in alcohol consumption in nearly four million people in Korea and found that after about 7 years, dementia was 21% less likely in mild drinkers and 17% less likely in moderate drinkers. by Wagamaga

Interesting study, I wonder if they have any way to tease out the difference between drinking and people who are more social so they drink socially more often. I have a feeling it’s the connection and socializing that helps with dementia.

Long covid is what’s making me worry. A lot of people don’t realise that the origin virus did massive damage to the immune system, especially in people with moderate to low health.
