Each point is a seven-day rolling window of complete UTC days; a point is comparable only when at least 100 analyzed posts or comments fall inside it. A day with no analyzed records counts as zero; missing coverage is marked and never shown as zero. The series ends at the latest complete analyzed day — it never extends into the current incomplete day. How attention is measured.

Im 4/4. My grandpa, great grandma, numerous aunts / uncles, my dad. All had and gone. I had already chose to not have kids before finding out in my 40s im 4/4. Now 49. I keep hoping for some miracle scientific breakthrough in time for myself but that window is fast approaching. (Yes I know not everyone in the world with apoe 4 gets alz. In my family they do)

How heartbreaking. She was so young!! Did she have APOE 4?

I suggest your spouse and your kids ( if you have one) take the tests ( APOE4 and P-TAU217 ) for precaution. Prevention is the only possible cure for now. Stop it before it starts. Once it becomes symptomatic, then it is too late. The symptoms may show up 10-30 years later. There are many case studies show that those who carry the risks are able to avoid the disease earlier by changing lifestyle and specific therapies.

They have shown evidence that lifestyle meaning healthy eating, exercise, etc. delay the symptoms of AD(NIH.gov). You are correct that there is no cure, nor medication that will slow the process down; however I would have taken another 10 years of clarity for sure. But there’s no education. That’s why I mentioned testing, merely a blood test to check for that APOE 4 bio marker. If you show up positive,they can at least educate you on how lifestyle will affect you. APOE does not guarantee you will get AD. It increases your chances I think 60%. The 2020 Lancet Commission on Dementia Prevention, Intervention and Care reported that **fully addressing 12 lifestyle risk factors can prevent or delay up to 40% of dementia cases** \[**1**\]. These risk factors include less education, hearing impairment, smoking, depression, physical inactivity, traumatic brain injury, high blood pressure, social isolation, air pollution, diabetes, obesity, and excessive alcohol consumption. What if you have a genetic risk factor? Apolipoprotein E, commonly known as APOE, is a gene associated with varying risk of developing Alzheimer's disease, depending on which variant you have. There are three different variants—APOE2, APOE3, and APOE4—and you have two copies, one each from your mother and father. The APOE2 variant is the rarest form of APOE and is associated with a reduced risk for Alzheimer's. The APOE3 variant is the most common and has an average risk for Alzheimer's. The APOE4 variant, present in up to 15% of people, increases the risk for Alzheimer's disease. It is important to note that having one or even two copies of the APOE4 variant does not mean the individual will definitely develop Alzheimer’s disease. Similarly, not having the APOE4 variant does not mean the individual will never get Alzheimer’s.

60% of patients admitted into the ER with Septic Shock will eventually end up with dementia of some sort or at least cognitive difficulties. If their injury caused a restriction in oxygen to the brain, called a Hypoxic Brain Trauma. Like in my case I stopped breathing 2X during surgery. My BP was30’s over single digit(I thought the surgeon said 36/3 but I was severely medicated). I was not getting oxygen to the core of my brain. Also I am unsure how long my BP was so low. Anyway, Anoxic/Hypoxic brain injuries WILL and can lead to AD. You may need to have the APOE 4 bio marker tho. BTW, my opinions are based only on my experience, however I have been fortunate enough to be living both sides of this stupid disease. There is a reason for everything though and my experience has led me to advocacy. And my main goal is education because that will be the only thing/way that could possibly help lessen the burden on care givers.
