Hormone and Information Processing Study (HIP)
Testosterone Supplementation in Men With MCI
Panoramica dello studio
Stato
Intervento / Trattamento
Descrizione dettagliata
Natural age related declines in testosterone (T) are associated with decreases in cognitive abilities independent of health status. Low T levels over time are associated with increased risk for developing Alzheimer's disease (AD). These findings suggest that men with low T levels are most at risk for age-related cognitive decline and AD and therefore most likely to benefit from T supplementation to prevent the development of AD or age-associated cognitive decline. The current study will assess cognition, mood, and cerebral spinal fluid (CSF) biomarker response to T supplementation in older men with mild cognitive impairment (MCI) and low T levels.
Participants will be randomized to either receive T treatment or a placebo for six months. Participants will come in for about five visits within the span of six months where they will complete cognitive & memory tests, fill out mood questionnaires, and have their blood drawn to monitor the medication level. A sample of blood will also be taken at one visit to test for apolipoprotein E (APOE), which is a genetic risk factor associated with AD. Participants will have the option to get a spinal tap in order to measure biological markers associated with Alzheimer's disease including beta-amyloid 1-40, 42, total-tau, and phosphorylated-tau-181-231. This will require an additional two visits.

Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
---|---|---|
Behavioral & Mood Measure: Profile of Mood States (POMS)
Lasso di tempo: Baseline, 3 and 6 months
|
Values represent self evaluation of vigor-activity.
The scale compares t-scores of participants to published norms (range 0-100), and higher scores indicate elevated emotion in subscale.
Higher t-scores in vigor-activity subscale are considered favorable.
Month 3 and Month 6 values display change from baseline.
|
Baseline, 3 and 6 months
|
Cognitive Changes Measured by Neuropsychological Tests: Rey Auditory Verbal Learning Test
Lasso di tempo: Baseline, 3 and 6 months
|
Values represent total score in Long Delay Word List Recall.
Higher score indicates higher level of functioning (range 0-15).
Month 3 and Month 6 indicate change from baseline.
|
Baseline, 3 and 6 months
|
Geriatric Depression Scale (GDS)
Lasso di tempo: Baseline, Month 3, Month 6
|
Values represent self evaluation of depression (range 0-30).
Higher scores indicate a more depressed mood.
Month 3 and Month 6 indicate change from baseline.
|
Baseline, Month 3, Month 6
|
Short-Form Health Survey (SF-36)
Lasso di tempo: Baseline, Month 3, Month 6
|
Self assessment of Physical Functioning in Health Survey.
Higher scores indicate a higher level of functioning (range 0-100).
Month 3 and 6 values represent change from baseline in subscale.
