Abstract
Alzheimer's disease and related dementias have made a considerable impact on society, and can take a significant toll on familial caregivers. Recent successful caregiving interventions suggest a promising future, though informed research design, a priori, is paramount in ensuring quality results that the Government and public may use to make informed policy and personal healthcare decisions. Research designs including basic science, randomized controlled trials (RCTs), qualitative, and quasi-experimental designs serve as the primary basis for discussion with literary examples and caveats.
