The effects of type 2 diabetes already include a wide range of frightening health conditions like ED, cancer, loss of limbs and cardiovascular disease, but things have just gotten worse.
A recent study have revealed that type 2 diabetes can ruin the one thing all of us want to keep more than anything else.
In recent years, many studies have been published that link type 2 diabetes with reduced cognitive functioning. Diabetics have worse memory skills, linguistic ability, and thinking skills as they get older than non-diabetics.
The first cognitive impairment that scientists noticed in diabetics was their memory. They performed much worse on declarative memory than non-diabetics. Declarative memory is the ability to remember something that requires language to be remembered.
For example, if you remember your first date, you can remember it in images (episodic memory). If you are trying to remember your company’s marketing strategy, you cannot do it without language (declarative memory).
The declarative memory of diabetics is affected more severely than their other cognitive functions like attention, decision making, and psychomotor efficiency.
To explain this, neuroscientists took images of their brains and discovered that their hippocampi were smaller than those of non-diabetics. The hippocampus is the brain’s main memory center, located in the temporal lobe.
It, therefore, seems as if type 2 diabetes actually reduces the size of people’s brains, probably because diabetes involves a resistance to insulin. If your body cannot use insulin properly, it cannot convert glucose into the energy that your organs need to function and maintain themselves.
Scientists then wondered whether emotional memory was also affected, as the neural circuits used by declarative memory overlap with those used by emotional memory. In various studies, they discovered that this was indeed the case. Diabetics had worse emotional memory than non-diabetics.
Emotional memory is the ability to remember, for example, that you are meant to fear the spider that bit you yesterday, or that your psychopathic child has the tendency to hurt you.
Now, experts have also established that diabetics are worse at verbal fluency than non-diabetics. Verbal fluency is the ability to remember words that fit some pattern. If you are asked to make a list of animals or a list of fruits and you can remember only five in one minute, your verbal fluency is obviously poor.
Beyond the game of recalling animal names, verbal fluency is actually an essential skill to get along properly. For example, if your employer asks you to list the tools that you need to finish the job, or your spouse wants you to make a shopping list, you must have reasonably good verbal fluency. They do not want to wait for hours while you struggle to produce the words.
This differs from declarative memory, as it involves the ability to generate a list of words that fall into specific categories. In declarative memory, you must remember only a thing. In verbal fluency, you must attend to a category and generate the entries from various facts in your declarative memory. The categorization is the key.
Areas in the brain that surround the hippocampus help with verbal fluency, which suggests that the damage brought about by type 2 diabetes is worse than first thought.
Interestingly, the hippocampus is also the first part of the brain that tends to be damaged by Alzheimer’s disease. This explains why memory is the first ability to be impaired in sufferers of it.
Alzheimer’s patients are also poor at declarative memory, emotional memory, and verbal fluency, as diabetics are.
Therefore, it seems as if type 2 diabetes can cause something similar to Alzheimer’s, and it can produce it in much younger people.
If there is a light at the end of this tunnel, it is the fact that studies prove that you can improve the cognitive dysfunction associated with type 2 diabetes by controlling the diabetes properly. If the brain receives enough glucose to use as energy, the cognitive impairments become less severe or even restore completely if you manage to fully reverse your type 2 diabetes.
your article never considered that a lot of medicines that are taken by diabetics cause cognitive decline. such as high blood pressure medication and especially statin drugs in other words cholesterol-lowering drugs. also these two classes of drugs tend to raise blood sugar so more diabetic medicine is needed is just one big vicious cycle.
Maybe the diabetic is B12 deficient. Metformin is deadly for B12.
