A Study to Compare Genetic Variations of IGF-I and IGF-II

The purpose of this study is to determine if insulin-like growth factors (IGF) play a role in the development of dementia, specifically Alzheimer's disease (AD). The study will compare results from genetic testing between patients with AD and two other groups: younger biological family members of the AD patients and individuals without AD matched by age to the AD patients.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Men and women between the ages of 50 and 81 years old who have a diagnosis of dementia
  • Men and women who are at least 18 years old and are biologically related to the study subject with dementia
  • Control subjects must not have a diagnosis of dementia and must be matched in age to the study subjects with dementia

Exclusion criteria

  • Biological family members with a diagnosis of dementia
  • Age-matched control subjects with a diagnosis of dementia

Treatment and study plan

Primary outcomes

  1. Genetic polymorphisms of insulin-like growth factors

    Time frame: Single clinic visit (day 1)

    This study consists of a single clinic visit. After subject has completed the informed consent process and meets eligibility criteria, a blood sample and a saliva sample will be collected. Genetic results from this one-time specimen collection will be evaluated and compared with results from participants in the other two study groups. Outcomes will be measured comparatively.

Secondary outcomes

  1. Genetic testing of Apolipoprotein (APO) E4

    Time frame: Single clinic visit (day 1)

    This study consists of a single clinic visit. After subject has completed the informed consent process and meets eligibility criteria, a blood sample and a saliva sample will be collected. Genetic results from this one-time specimen collection will be evaluated and compared with results from participants in the other two study groups. Outcomes will be measured comparatively.
