According to 2022 data from the U.S. Centers for Disease Control and Prevention (CDC), the main causes of death in Washington State were cancer, heart disease, and accidents. Alzheimer’s disease was the fourth leading cause.
This differs from national statistics, where Alzheimer’s disease was the sixth leading cause of death. At the national level, heart disease, cancer, unintentional injuries, stroke, and chronic lower respiratory diseases were more prevalent (via CDC).
The Alzheimer’s Association notes that Alzheimer’s is the most common cause of dementia, accounting for 60% to 80% of cases. Dementia is a broad term for a significant loss of memory and cognitive function that affects daily life. Most Alzheimer’s patients are 65 or older. The disease is believed to result from the accumulation of beta-amyloid plaques and tau tangles in the brain.
It’s unclear why Alzheimer’s disease is more prevalent in Washington than elsewhere in the U.S. However, public health experts have provided some insights into this intriguing pattern.
Why there might be more Alzheimer’s disease deaths in Washington
One theory for the higher death rate is the state’s cloudy weather. Sunlight exposure promotes vitamin D production in the skin, and low vitamin D levels are linked to a higher risk of dementia. It is also speculated that Washington may be more proficient in collecting and verifying health data compared to other states. Additionally, differences in how medical professionals in Washington recognize and code Alzheimer’s deaths could play a role (per PBS).
It’s worth mentioning that in the past, the death rate from Alzheimer’s in Washington was even higher. In 2016, it was the third leading cause of death in the state, prompting health officials to develop a strategic plan to address the issue. This document has been updated and will continue to guide efforts through at least 2028.
Alzheimer’s disease prevention and treatment
Although the reasons for Washington’s elevated Alzheimer’s death rate remain unknown, the CDC suggests several ways to reduce your risk of developing Alzheimer’s disease. They recommend regular physical activity (find out how many steps you need to take daily to lower your dementia risk), avoiding or reducing smoking and alcohol consumption, and managing diabetes and high blood pressure to lower your risk.
Another recommendation is to address hearing loss, such as through cochlear implants, which may decrease the likelihood of developing dementia. Scientists believe hearing loss contributes to dementia risk because it forces the brain to work harder, diverting resources from memory and cognition. Difficulty in social interaction and staying mentally active due to hearing loss can also increase risk.
While there is no cure for Alzheimer’s disease, certain medications can slow its progression. Additionally, medications are available to aid memory and cognitive function and address symptoms like sleep disturbances, agitation, hallucinations, and delusions.
