Question: My husband recently started using insulin injections. Would that cause his mind to atrophy? He sits in his chair all day until bedtime reading and reacting to politics on his smartphone. Occasionaly goes outside to do yardwork for 1/2-1 hr. Then comes back in with a reason the weather or something stops him. He has recently been acting as if I am his enemy, blames me for anything he finds to be negative. Has started telling me there are things wrong with me, I am dirty (I'm not), I am losing my memory (not), and on and on. It's getting very hard for me to keep a positive attitude. Is he going crazy, or just mean?

Brief Answer:
Not due to insulin

Detailed Answer:
I read your question carefully and I understand your concern.

Regarding Insulin injections, they do not produce brain atrophy. They do not cause those symptoms in themselves. The only scenario where they could be involved would be if they excessively lowered his blood glucose which may be manifested with aggressive behavior. But there would usually be other symptoms and also you mention his symptoms as constant, not only occurring after an insulin shot.

As for these changes in character they can have several causes. A brain structural lesion such as a tumor or stroke in certain areas of the brain dealing with behavior may at times be the cause.
Some types of dementia may also have behavior changes as their initial manifestation.
Lastly but perhaps more likely depression may simply be the cause, changes in his health status starting new medications may have contributed to that.

So I would advise a consult with a neurologist or a psychiatrist. If neurological signs are found on physical exam which may indicate a brain lesion than imaging may be required. If there are changes indicating dementia some blood tests might be needed as well. If everything is normal, then as I said depression may be a cause and its treatment may be considered.

I remain at your disposal for other questions.

Hello, I have a question regarding insulin resistance and dehydration. I m a Type 1 Insulin Dependent diabetic. Have been for nearly 16 years. My HA1c was last 4.9% so I keep my numbers extremely regulated. Anyways to the question, can severe dehydration lead to insulin resistance? I have some idea of the physiology but I want to understand it thoroughly. Let me give you the story first so you can maybe give me the walk through of it all especially the dehydration and insulin resistance. So after heavy drinking ( not something I do often at all....) , 6-7 hours of hard alcoholic drinks and no water during this time. I went to sleep woke up the next morning feeling very thirsty, it d been about 18 hours since I had a sip of water. So I drank some, and became nauseous. My sugars kept rising, initially was 192, ended up at 425 before I had to call 911. I was not holding down water.. my glucose was rising, I was taking massive amounts of insulin, somewhere in the 80-100 units of Humalog range. I take ~60 units in a day and this was in a matter of 12 hours probably. And my numbers did not drop. My question is why and whats the physiology behind the insulin not working? Something with the dehydration but Im not quite understand it. Please answer this if you can. Oh and I was not consuming food during this time so the glucose rise was not from carbohydrates.

Hi, my name is Eva and my son (2) has Glucose galactose malabsorption. Do you know if digestive enzymes could help to ease this condition? I am also worried that in time he might have some renal or cardiovascular problems. So far he seems very healthy and is growing just fine on his fructose based diet. Thank you
