Brief Summary:
The purpose of this study is to examine the effects of testosterone (T) replacement on changes in thinking and memory, as well as mood in older men with mild cognitive impairment (MCI) and low T levels. The study will also examine whether taking testosterone has effects on biological markers related to Alzheimer's disease.

Condition or disease Intervention/treatment Phase
Mild Cognitive Impairment Alzheimer's Disease Drug: testosterone gel Drug: placebo gel Phase 3

Detailed Description:

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.

Arm Intervention/treatment
Experimental: Study drug; testosterone transdermal gel
Dose will be adjusted as needed to maintain a target total T level of 500-900 ng/dl
Drug: testosterone gel
50-100mg applied topically daily for six months
Other Name: Solvay Testosterone Gel

Placebo Comparator: 2 Drug: placebo gel
applied topically daily for six months

Primary Outcome Measures :
  1. Behavioral & Mood Measure: Profile of Mood States (POMS) [ Time Frame: 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.

  2. Cognitive Changes Measured by Neuropsychological Tests: Rey Auditory Verbal Learning Test [ Time Frame: 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.

  3. Geriatric Depression Scale (GDS) [ Time Frame: 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.

  4. Short-Form Health Survey (SF-36) [ Time Frame: 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.
