This study is collecting tissue specimens (blood, urine and saliva) from up to 1000 patients, with and without cognitive disorders, to store in the Bio Bank for future research. The specimens could be used in future research projects that could help improve the accuracy of diagnosis of a disease, predict who might develop a disease, help monitor the disease, or improve the understanding of the disease. Patients are only being recruited from Beaumont Hospitals Geriatric Clinic.

Up to 1000 patients, with or without diagnosed cognitive disorders, are asked to participate by providing the investigators with blood, urine and saliva specimens to be stored in a Bio Bank for future research. Patients will be asked to participate on a yearly basis for up to 5 to 10 years by providing the investigators with the above-mentioned specimens, and also having a physical exam and having some cognitive testing performed at the initial visit and yearly visits.

Examples of the types of research are: new methods for improving the diagnosis and treatment of age-related cognitive disorders, new areas of biology, new areas of biotechnology, and possibly genetic research. If you do not want your specimens used for any specific type of research, you may specify that on the consent form.

Inclusion Criteria:

1. At least 60 years of age.
2. Willing and able to complete all specimen donations and neuropsychological examinations.
3. Individuals identified as having some form of cognitive impairment require a study partner with 1-2 times per week contact (can be in person and/or telephone), who will accompany them to study visits(s).

Exclusion Criteria:

1. Presence of significant sensory deficits (e.g., visual or hearing), motor deficits (e.g., paralysis), or medical conditions that would preclude the completion of the neuropsychological or other study instruments.
2. DMS-IV diagnosis of substance abuse disorder.
3. Presence of a major medical or terminal illness that may affect the participation of the patient in the study.
4. Known active malignancy, or history of malignancy within the last 5 years (other than basal cell carcinoma), severe organ failure, metabolic or hematologic disorders, or post-encephalitic syndrome.

Patients will be obtained from individuals seen by the physicians affiliated with the Division of Geriatric Medicine at Beaumont Hospital in the Geriatric Clinic.

If IPD are shared, it will be results of genomic and proteomic testing. As this testing was done throughout the study and is ongoing, some results are already available. Anyone interested would contact the principal investigator.
