Brief summary

The purpose of this study is to find out if therapy with hormones (such as Lupron, Casodex, Zolodex or Degarelix) change a person's thinking abilities.

Detailed description

To find out if this treatment changes things like memory, learning, or concentration. This study is being done to learn more about the effects of this treatment and to help men in the future who use the hormones Lupron, Casodex, Zolodex or Degarelix. If you choose to take part, you will be asked to do the following: Fill out questionnaires that ask about: * Your age, eduction, race, and income * Depression * Stress * Energy level * Pain * Memory * Ability to perform daily tasks such as eating, dressing, and taking a shower Research staff will evaluate you on the following: * Memory * How you prefer to learn new information * Copying designs such as rectangles, squares, and circles * How quickly you think * Your attention span * How well you plan and organize shapes and colors into specific categories As such, at MSKCC will be contacting a portion of prospective subjects via mail or email to offer them the opportunity to plan for and allocate the necessary time in their personal schedules, should they be interested in the study.

Interventions

BEHAVIORALQuestionaires

We will use a 6-month longitudinal design to assess the short-term cognitive effects of androgen ablation therapy. We will collect 6-month longitudinal data on 170 men with prostate cancer. All 170 men will be hormone naïve at the start of this study (Hormone Naïve Group). These 170 men will consist of two subgroups. The first subgroup will comprise 70 men with prostate cancer age 65 and older scheduled to start androgen ablation therapy. Their cognitive functioning will be assessed prior to starting androgen ablation therapy or within 21 days after initiation, (i.e. baseline) and then 6 months later (Androgen Ablation Subgroup).The second subgroup will serve as a control group, and consist of 100 men with prostate cancer age 65 and older who are at least 1-year post definitive localized treatment with no evidence of disease and no plan to start androgen ablation therapy (No Androgen Ablation Subgroup).

DEVICEfMRI scan (optional)

Main study participants will be offered to complete an optional fMRI. Fifteen participants from the No Androgen Ablation Subgroup and 15 participants from the Comparison Androgen Ablation Subgroup or Longitudinal Androgen Ablation Subgroup will be recruited for this portion of the study. The fMRI will be scheduled either the same day as the neurocognitive assessment or within eight weeks of the neurocognitive testing. The fMRI will be performed only once at baseline for the Comparison Androgen Ablation Subgroup. The fMRI will be performed at the follow-up time point for the Longitudinal Androgen Ablation Subgroup. The fMRI will be performed at baseline for the No Androgen Ablation Subgroup; if the fMRI can not be completed at baseline (due to participant schedule conflict, lack of fMRI availability, staff schedule conflict, etc.), then the scan will be conducted at the follow-up time point if possible.

Inclusion criteria

is the same at both sites, and is outlined below: Inclusion Criteria: Comparison Androgen Ablation Group 1. Diagnosis of prostate cancer 2. Age 65 or older 3. Ability to converse, write and read English 4. In the investigator's judgment, participants must have satisfactory cognitive function to provide valid informed consent and participate in the neurocognitive testing. The Blessed Orientation-Memory-Concentration test (BOMC) will be used as a cognitive screening tool. Patients must have a BOMC score of less than or equal to 11. 5. Able to provide informed consent 6. Have been on continuous androgen ablation therapy for 6 months to-3 years Longitudinal Androgen Ablation Subgroup 1. Diagnosis of prostate cancer 2. Age 65 or older 3. Ability to converse, write and read English 4. Able to provide informed consent 5. In the investigator's judgment, participants must have satisfactory cognitive function to provide valid informed consent and participate in the neurocognitive testing. The Blessed Orientation-Memory-Concentration test (BOMC) will be used as a cognitive screening tool. Patients must have a BOMC score of less than or equal to 11. 6. Starting androgen ablation therapy or started within the past 21 days 7. No androgen ablation therapy within the past year No Androgen Ablation Subgroup 1. Diagnosis of prostate cancer 2. Age 65 or older 3. In the investigator's judgment, participants must have satisfactory cognitive function to provide valid informed consent and participate in the neurocognitive testing. The Blessed Orientation-Memory-Concentration test (BOMC) will be used as a cognitive screening tool. Patients must have a BOMC score of less than or equal to 11. 4. At least 1-year post definitive localized treatment 5. Ability to converse, write and read English 6. Able to provide informed consent 7. Not anticipated to start androgen ablation therapy 8. No history of androgen ablation therapy

Exclusion criteria

All Groups 1. Previous or current treatment with chemotherapy 2. As per medical record or self-report, a history of central nervous system stroke, history of traumatic brain injury, or diagnosis of neurogenerative disorder that affects cognitive function (e.g. Alzheimer's, Parkinson's, Multiple Sclerosis, dementia, seizure disorders, etc.) 3. History of untreated psychiatric disease 4. As per medical record or self-report, history of loss of consciousness for 60+ minutes and/or admitted to the hospital for a head injury 5. Current use of opioids 6. History of developmental disorders 7. Current or history of alcohol or substance abuse 8.
