Mild Cognitive Impairment (MCI) Mild cognitive impairment is an early stage of cognitive change. – Patients or family members notice changes in thinking. – Impairment is documented by formal testing. – Patient is able to independently carry out daily activities. People with MCI are more likely to develop Alzheimer’s disease or other dementias than people without MCI.
What is Dementia? Dementia is a decline in mental ability, including memory, that is severe enough to result in loss of independence in typical daily activities. Dementia is most common in older adults and has many known causes. Alzheimer’s disease is the most common type of dementia in older adults.
What is Alzheimer’s Disease? When cognitive impairment is due to Alzheimer’s disease, symptoms usually start gradually and progress slowly, over many years. In its early stages, memory loss is mild, but with latestage Alzheimer's, individuals lose the ability to carry on a conversation and respond to their environment. There is no cure for Alzheimer’s disease, but there are opportunities for early diagnosis and interventions which temporarily slow the worsening of dementia symptoms and improve quality of life.

Alzheimer’s Disease and AI/ANs The number of AI/ANs age 65 and older is growing fast. The US Census Bureau estimated that in 2012, 266,000 AI/ANs were aged 65 and older According to projections, the population of Native elders in this age range will almost quadruple by 2050, to 996,000. Many experts believe that Alzheimer's disease is underdiagnosed in our communities.
AI/AN Dementia Risk: What do we know? Two recent studies of Alzheimer’s disease: Mayeda et al. Alzheimer’s & Dementia (2016) ‒ AI/ANs and African Americans have the highest incidence of dementia among all racial and ethnic groups. Chen and Panegyres. Journal of Alzheimer’s Disease (2016) ‒ AI/ANs and Native Hawaiians have twice the risk of early-onset dementia (before age 65) relative to Whites (lowest risk group).
Challenges in Addressing Alzheimer’s among AI/ANs Fragmented healthcare and surveillance systems ‒ 26 hospitals operated by the Indian Health Service ‒ 19 tribally operated hospitals Inconsistencies in diagnostic criteria Known barriers to screening ‒ Lack of transportation ‒ Little continuity of care Alzheimer’s stigma and myths ‒ “Normal part of aging” ‒ “Can’t be treated” ‒ Patients might be labeled “crazy” and could be removed from their homes
Why diagnose Alzheimer’s disease? Memory loss may be caused by other issues, such as sleep apnea, alcohol use, stroke, traumatic brain injury, or the side effects of medication. A diagnosis of Alzheimer’s disease means that the patient’s memory and thinking problems are expected to gradually worsen. It is important to begin planning for future care needs, ideally while the patient can participate in the discussion. An accurate diagnosis can help the patient and family obtain access to appropriate resources for education and support.

Early Detection Fewer than 50% of cases of dementia are diagnosed in a clinical setting. Family members and healthcare providers play a critical role in detecting mild cognitive impairment and dementia. Better diagnostic aids are needed ‒ Culturally relevant ‒ Brief Connoly et al, Aging and Mental Health, 2011; Mattson, et al. JAMA; 302(4):385-393. ‒ Cost-effective

Partnership Activities
Other Research Activities “Alzheimer's Disease Research Study for American Indians and Alaska Natives” is a pilot study that was funded to: ‒ Develop and deliver a presentation on Alzheimer’s disease research ‒ Administer pre- and post-presentation surveys ‒ Conduct focus groups with AI/ANs on the impact of the presentation
Research Activities at University of Washington AI/ANs are under-enrolled in clinical research and population-based studies. The University of Washington Alzheimer’s Disease Research Center is a site for clinical trials and studies of potential treatments, prevention strategies, and new diagnostic approaches for Alzheimer’s disease and related neurodegenerative conditions. http://depts.washington.edu/mbwc/research/clinica l-trials
Research Opportunities at University of Washington Examples of intervention/treatment studies EMERGE; CONNECT: placebo-controlled drug trials for people with early-stage Alzheimer’s disease A4: placebo-controlled drug trial for symptomfree older adults Estia: computer games for older people with depression
