A researcher at Iowa State University finds a link between the insulin that regulates blood sugar in our bodies and Alzheimer’s disease. I-S-U’s Auriel Willette conducted the study with a researcher from the Wisconsin Alzheimer’s Institute. “In certain brain regions that are affected by Alzheimer’s disease, they show that these neurons are using less and less blood sugar. And so, these problems with using blood sugar were also selectively related to — in these same people — to having problems with memory,” Willette says.

People who are obese tend to become insulin resistant, which could lead to Alzheimer’s disease. Willette says they found the link between the insulin resistance and memory issues. “Immediate memory over the course of a couple of minutes, all the way down to 20 minutes later,” Willette says. He says this study may be enough warning for people to think more about losing weight now, to prevent the possible onset of Alzheimers. Willette wants to do more work on the impact of blood sugar levels on the brain.

“Some subsequent work that I want to do is trying to see…if you are overweight or if you are obese, if you do engage in moderate exercise, could that have an affect on the brain where we don’t see the relationship we’re seeing here?,” Willette says. Willette says having less sugar means the brain has less energy to relay information and function, but there’s a lot that isn’t known.

“We as brain scientists know very little about the dynamics of how this works,” Willette says. “We are just now kind of beginning to understand this as to how we perceive food and things along those lines.” He says this new link involving brain sugar and insulin raises more questions. “In relation to how insulin might give us that extra jolt of energy to be able to figure something out or to remember something or to make a new memory — things along those lines — we really don’t understand much of how that works at all. It’s just a really, really new field, and so know we are just trying to puzzle out what it all means,” according to Willette.

Willette’s findings were published in the Journal of the American Medical Association Neurology.

The good news just keeps getting better if you are selling your home in Iowa. According to the Iowa Association of Realtors (IAR), sale prices and number of homes sold continue their upward trend. Sales increased almost 10 percent and average days on market reached a new 3 year low. Homes continue to sell at a fast pace in most communities. Days on market dropped to 69 in June, which is the fastest rate in over 3 years. That’s a 14.8 percent improvement from June of 2014.

Sales increased 9.7 percent from a year ago. 4,749 homes were sold last month as compared to 4,329 homes that sold in June 2014. Active listings were up 3.7 percent and Pending listings were up 7.6 percent when compared to last June. The IAR’s 2015 June Housing Trends Report shows the median sale price rose 6.0 percent. In June 2014 the median sale price was $143,900 while the median price last month was $152,500. The days on market of 77 days hit a new low when comparing second quarter performance of this year to the past eight years.

IAR President Jon Yocum said “The second quarter statistics demonstrate the strong housing market we have had in Iowa this year. In fact, the second quarter of 2015 shows a higher number of sold properties than we have had in the last eight years. We’ve had a 10 percent increase in sold properties when comparing to the second quarter of last year. Buyers are realizing that it is still a good time to buy with relatively low interest rates. Homeowners are hearing that homes are selling fast with low inventory levels. It is a great time for them to put their homes on the market.”
