High Cholesterol and Memory Loss

The tendency to build up high cholesterol may run in families, but excessively high levels are usually the result of a poor diet high in saturated fats and calories, combined with little or no exercise. It is commonly known that high cholesterol, particularly LDL, builds plaque in your arteries and can lead to heart trouble, But did you know that high cholesterol could lead to memory loss? I found this article to be quite interesting and I thought it may be helpful to you.

"Memory loss is a common complaint among people as they age. Roughly one in ten older Americans are mentally impaired, with symptoms ranging from mild memory problems to severe dementia. Many people want to know -- is there a way to keep my mind sharp and healthy?

Scientists now believe that lowering your cholesterol may be part of the answer, at least for women. While cholesterol has long been associated with heart disease, researchers in California have found that women who have gone through menopause and have high cholesterol levels may be more likely to suffer from dementia and mental sluggishness than those with normal cholesterol levels.

Researchers measured levels of total cholesterol, HDL ("good") cholesterol, LDL ("bad") cholesterol, and triglycerides (fatty substances in the blood) in 1,037 older women and again 4 years later. At the end of the study, the women completed a questionnaire that measured their ability to concentrate, remember, and reason.

Surprising results

The researchers found that women with higher total and LDL cholesterol scored lower on the memory test than those with normal cholesterol levels. In fact, women with the highest levels of total and LDL cholesterol were nearly twice as likely to have memory loss as those with lower cholesterol levels.

Additionally, women whose LDL and total cholesterol declined or remained the same throughout the 4-year study period were half as likely to suffer from mental problems than those whose levels increased over the same time period.

The researchers found no association between HDL or triglyceride levels and brain function in the study participants.

Fat-free thinking?

"These findings suggest that lowering total cholesterol and LDL cholesterol may be a potential strategy for preventing the development of cognitive impairment or dementia," the researchers conclude.

While more studies need to be completed to determine just how much of an effect cholesterol has the brain, the benefits of a low fat, low cholesterol diet on heart health have already been shown time and time again.

Discussion:
When was the last time you had your cholesterol checked? Did you know that exercise, both cardiovascular and weight resistance, help reduce cholesterol? If you have been diagnosed with high cholesterol, what are you doing to reduce it?

    I've known I have high cholesterol since my 20's (when it was first checked). I just had it tested again and the doctor told me about this research. This definitely had an impact on my motivation to exercise and eat better! Funny how I wasn't that concerned about my heart health, but I am definitely concerned about my memory going! I just hope I can maintain the motivation I found in the doctor's office over the long term.

      Hi Chloe -

      There are 2 types of motivation; internal and external (see earlier post on Motivation). What you need to do is find out motivates you and use that to continue with your exercise. Maybe you could even post a reminder/note in your bathroom (where nobody else will see it) about why you are exercising. If that doesn't work and you still need help with motivation, you know where to find me.

      Thanks for your comment. I appreciate it!

      Steve
