GUY’S GOTTA TALK ABOUT…TYPE 2 DIABETES #33: Type 2 Diabetes & Alzheimer’s

For the first time since I started this blog eleven years ago, it’s going to be about me. I was diagnosed with Type 2 Diabetes two weeks ago. While people are happy to talk about their experiences with diabetes, I WASN’T comfortable with talking about diabetes. My wife is Type 2, as are several friends of ours. The “other Type” of diabetes was what caused the death of my Best Man a year after my wife and I got married. He was diagnosed with diabetes when he was a kid. It was called Juvenile Diabetes then. Today it’s Type 1. Since then, I haven’t WANTED to talk about diabetes at all. But…for my own education and maybe helping someone else, and not one to shut up for any known reason, I’m reopening my blog rather than starting a new one. I MAY take a pause and write about Breast Cancer or Alzheimer’s as medical headlines dictate; but this time I’m going to drag anyone along who wants to join my HIGHLY RELUCTANT journey toward better understanding of my life with Type 2 Diabetes. You’re Welcome to join me!


Over the years (14 of them, actually…), I’ve written on breast cancer (my wife was diagnosed with it in 2011); Alzheimer’s (my dad was diagnosed in 2016) and finally Type 2 diabetes when I was diagnosed in October of 2022.

Well, my nightmare is coming true: “The relationship between diabetes and Alzheimer's Disease (AD) has increasingly been recognized.” The paper, “Diabetes and Alzheimer’s Disease” (published in JOURNAL OF DIABETES, 2025 May 19, see Source: below) concludes:

“There is, then, a strong connection between diabetes and AD, reflecting underlying insulin resistance leading to [Aβ accumulation and tau hyperphosphorylation] (colloquially known as plaques and tangle). Appropriately powered clinical trials of GLP‐1 RAs and SGLT2 inhibitors, as well as of further potential therapies, are needed to determine effective strategies for prevention and treatment. Conceptually, physical activity and a healthy diet can improve insulin sensitivity and should be effective in reducing AD, but existing evidence to develop effective lifestyle approaches is limited, and this too appears to be an important potential area for research.”

The first part is totally disheartening, and makes me feel like there’s nothing for me to do but to lie down and let the Alzheimer’s and resign myself to sharing inappropriate anecdotes with my children and other friends, or forgetting the name of my youngest child…

Both of those happened with Dad. Outbursts of anger, as well (though, to be perfectly frank, Dad was well known for not only the anger thing, but also a getting in fights thing when he was a kid growing up in Loring Park (downtown Minneapolis).

It was the loss of his grip on reality that frightens me most. He called me a 3:00 am more than once to tell me that he thought that “Your mother has left me. I don’t know why.” I would have to calm him with the tale that my mother had passed away a few days/months/years ago. Which would bring him crashing into reality in total silence.

Those times, or when I had to explain that the person driving him home from a fishing trip was my younger brother, Paul. Or explaining over and over that Mom had died…

Now, I find out that my being a Type 2 diabetic increases the chance of my developing those plaques and tangles and a greater chance of developing Alzheimer’s.

Finally, I read the WORST part: “Clinical trials are underway to investigate the potential of the GLP‐1 RA semaglutide (which you may know as the WONDERDRUG used by people desperate to lose weight by giving themselves shots of…well, I could write out the actual name, but the brand names of semaglutide start with O, W, M, Z and their ilk) rather than controlling their appetites. This has led to insurance coverage being reduced or eliminated in modifying Type 2 diabetics. It is also preventing the potential to control and treat Alzheimer’s Disease among early‐stage symptomatic patients. The sodium‐glucose co‐transporter 2 Inhibitors (SGLT2i; known as those letters listed a few sentences ago) may also have neuroprotective antioxidant and anti‐inflammatory effects, increasing neurogenesis and synaptic activity and decreasing ischemic neuronal damage and mitochondrial dysfunction, as well as improving hyperglycemia and insulin sensitivity.”

So, there you go. First, Type 2 diabetes may lead to Alzheimer’s; and the treatment for both prevention and treatment has been adjudged to be nothing more than a cure for obesity. (and therefore ELECTIVE and therefore probably not covered by insurance or cash on the barrelhead...)

Have a nice day.

DIABETES RESEARCH RIGHT NOW! #30: Can the BRAIN ITSELF Be Targeted To Treat Type 2 Diabetes???

From the first moment I discovered I had been diagnosed with DIABETES, I joined a HUGE “club” that has been rapidly expanding since it stopped being a death sentence in the early 20th Century. Currently, there are about HALF A BILLION PEOPLE who have Type 2 Diabetes. For the past 3500 years – dating back to Ancient Egypt – people have suffered from diabetes. Well, I’m one of them now… Not one to shut up for any known reason, I added a section to this blog…

Every month, I’ll be highlighting Diabetes research that is going on RIGHT NOW! Harvested from different websites, journals and podcasts, I’ll translate them into understandable English and share them with you. Today: “For several years, researchers have known that hyperactivity of a subset of neurons located in the hypothalamus, called AgRP neurons, is common in mice with diabetes.”


So…weirdly enough, I just finished a book called THE THREE POUND ENIGMA: The Human Brain and the Quest to Unlock Its Mysteries by Shannon Moffett (©2006). Granted, it’s technically nineteen (most likely 20) years out of date. Most of the book is a fascinating examination of what science and scientists had discovered about the brain up to that point.

But it didn’t talk about how playing with the BRAIN might have an effect on controlling Type 2 diabetes!

“For several years, researchers have known that hyperactivity of a subset of neurons located in the hypothalamus, called AgRP neurons, is common in mice with diabetes. These neurons are playing an outsized role in hyperglycemia and type 2 diabetes,” said UW Medicine endocrinologist Dr. Michael Schwartz, corresponding author of the paper.

What’s AgRP? “Agouti-related protein, is produced in the brain by the AgRP/NPY neuron. The cells controlled by the AgRP increase appetite and decrease metabolism and energy expenditure. It is one of the most potent and long-lasting of appetite stimulators.”

So, this protein come from the brain and makes me hungry and lazy!

How’d they figure out the connection between the brain and my Type 2 diabetes? (Not that it comes as any great surprise...)

 Once they discovered the connection, “…researchers…made AgRP neurons express tetanus toxin, which prevents the neurons from communicating with other neurons. Unexpectedly, this intervention normalized high blood sugar for months, despite having no effect on body weight or food consumption.”

“The new findings align with studies published by the same scientists showing that injection of a peptide called FGF1 directly into the brain also causes diabetes remission in mice. This effect was subsequently shown to involve sustained inhibition of AgRP neurons…Further research might help scientists to better understand the role of AgRP neurons in how the body normally controls blood sugar, and to ultimately translate these findings into human clinical trials, he added.”

WHOA!!! Amazing! (Weird how I just happened to be reading a book on how the brain works!)

So…if I understand this right, it may someday be possible for me to get a shot to the brain by a protein that makes neurons in my brain produce a TETANUS TOXIN...that abruptly causes the communication between neurons to STOP telling my body that it wants to eat more and exercise less? And this will make my blood sugars return to normal?

WOW!

Now don’t get me wrong – THIS IS NOT A TREATMENT YET!!!!!

But…it’s a possible treatment, AND has the advantage of removing from ME responsibility of taking ANY blame for being diabetic! Just the RESEARCH is communicating to the world that THIS WAS NOT MY FAULT!!! (Or the fault of my genetics!)
