TRT & Alzheimer's: A Pilot Study

[CoastWatcher]

Researchers hypothesized that TRT in older, hypogonadal men would improve cognition.

• Thirty six patients with a new diagnosis of Alzheimer's Disease were screened for hypogonadism.
• Ten of these patients, 28% had total testosterone values of less than 240 ng/dl and were enrolled in a pilot study - five received testosterone and five received a placebo.
• The protocol administered, 200mg of testosterone cypionate every two weeks, was a poor one (date of study was 2003).
• Measurement of total testosterone, CBC, PSA, and lipids was done at the three, six, nine, and twelve month mark of treatment.
• Total testosterone increased, a mean rise of 126.4 ng/dl, (meaning men were still hyogonadal in terms of symptoms).

In terms of Alzheimer-related symptoms, those in the group receiving testosterone all posted increased scores on Alzheimer's Disease Assessment Scale, and the Mini Mental Status Exam.

A small study, with a flawed testosterone protocol figuring prominently, nonetheless suggests that cognition can be positively influenced in Alzheimer's patients with the administration of testosterone.

Yes, TRT/HRT is one of the parts of Dr. Bredesen's original 36-point program for reversing dementia. A good discussion of the total program can be found here:

and the full protocol (at least at the time, it has since been expanded) is in the text of the study published in the journal Aging.

Testosterone therapy can damage brain health in Caucasian men

Forth Worth, Texas - Ads touting testosterone replacement therapy are ubiquitous on radio and television. But medical research has determined that its success at enhancing libido may come at a price.Researchers at University of North Texas Health Science Center in Fort Worth report that while testosterone replacement therapy can damage brain health in some Caucasian men, Mexican-Americans appear to be protected from negative effects of the sex hormone.In Caucasian men with elevated oxidative stress, testosterone replacement therapy raises the risk of damage to brain cells, said Rebecca Cunningham, PhD, Assistant Professor of Pharmacology and Neuroscience. But that’s not the case for Mexican-Americans, who do not appear to be affected by oxidative stress.The findings, published in the April issue of the Journal of Alzheimer’s Disease, could lead to a better understanding of the role ethnicity plays in brain diseases and cognition.“Different factors appear to drive dementia,” Cunningham said. “And these factors are dependent on the ethnicity of the person.”Oxidative stress, which can determine whether testosterone protects brains cells or damages them, occurs when there are more free radicals produced in the body than antioxidants. Many studies have found between 20 percent and 30 percent of aging men have no response or a negative response to testosterone therapy.“Our study shows that these negative effects occur only in Caucasian men with high oxidative stress,” Dr. Cunningham said.Testosterone therapy can improve libido, but it’s not beneficial across the board.“I would tell Caucasian men to be cautious about taking testosterone, especially if their oxidative stress levels are high,” Dr. Cunningham said.A blood test for oxidative stress, such as homocysteine, can help physicians determine who is a good candidate for testosterone replacement therapy.Mexican-American men appear to be protected from the deleterious effects, possibly because of higher levels of endogenous antioxidants, which are produced inside the body and act as their own line of defense against free radicals.###UNT Health Science Center The UNT Health Science Center comprises the Texas College of Osteopathic Medicine, Graduate School of Biomedical Sciences, School of Public Health, School of Health Professions and the UNT System College of Pharmacy.

Among men, androgens are associated with a decrease in Alzheimer's disease risk - PubMed

Sex hormones are hypothesized to play a role in developing Alzheimer's disease (AD). The effect of sex hormones on AD was assessed using Mendelian randomization (MR) analysis. Among women, genetically determined effects of sex hormones were limited or null. Among men, a higher concentration of...
