Subjective cognitive decline (SCD), the self-reported experience of worsening or more frequent memory loss or confusion, might be a symptom of early-stage dementia or future serious cognitive decline such as Alzheimer disease* or a related dementia (ADRD) (1). Established modifiable risk factors for ADRD include high blood pressure, inadequate physical activity, obesity, diabetes, depression, current cigarette smoking, and hearing loss (2). An estimated 6.5 million persons aged ≥65 years in the United States live with Alzheimer disease, the most common dementia (1). This number is projected to double by 2060, with the largest increase among non-Hispanic Black or African American (Black), and Hispanic or Latino (Hispanic) adults (1,3). Using data from the Behavioral Risk Factor Surveillance System (BRFSS), CDC assessed racial and ethnic, select demographic, and geographical differences in SCD prevalence, and prevalence of health care professional conversations among those reporting SCD. The age-adjusted prevalence of SCD during 2015-2020 was 9.6% among adults aged ≥45 years (5.0% of Asian or Pacific Islander [A/PI] adults, 9.3% of non-Hispanic White [White] adults, 10.1% of Black adults, 11.4% of Hispanic adults, and 16.7% of non-Hispanic American Indian or Alaska Native [AI/AN] adults). College education was associated with a lower prevalence of SCD among all racial and ethnic groups. Only 47.3% of adults with SCD reported that they had discussed confusion or memory loss with a health care professional. Discussing changes in cognition with a physician can allow for the identification of potentially treatable conditions, early detection of dementia, promotion of dementia risk reduction behaviors, and establishing a treatment or care plan to help adults remain healthy and independent for as long as possible.
主观认知下降(SCD),即自我报告的记忆或认知问题恶化或更频繁出现,可能是早期痴呆或未来严重认知衰退(如阿尔茨海默病*或相关痴呆症(ADRD))的症状(1)。已确定的 ADRD 可改变的风险因素包括高血压、身体活动不足、肥胖、糖尿病、抑郁、当前吸烟和听力损失(2)。据估计,美国有 650 万年龄≥65 岁的人患有阿尔茨海默病,这是最常见的痴呆症(1)。这一数字预计到 2060 年将翻一番,其中非西班牙裔黑人和非洲裔美国人(黑人)和西班牙裔或拉丁裔(西班牙裔)成年人的增幅最大(1,3)。使用行为风险因素监测系统(BRFSS)的数据,CDC 评估了 SCD 流行率以及报告 SCD 的人群中与卫生保健专业人员进行对话的流行率的种族和民族、特定人口统计学和地理差异。在 2015-2020 年期间,年龄调整后的 SCD 患病率在≥45 岁的成年人中为 9.6%(5.0%的亚洲或太平洋岛民[APIs]成年人、9.3%的非西班牙裔白人[白人]成年人、10.1%的黑人成年人、11.4%的西班牙裔成年人和 16.7%的非西班牙裔美洲印第安人或阿拉斯加原住民[AI/AN]成年人)。大学教育与所有种族和族裔群体的 SCD 患病率较低相关。只有 47.3%的 SCD 患者报告他们曾与卫生保健专业人员讨论过困惑或记忆丧失。与医生讨论认知变化可以识别潜在的可治疗疾病,早期发现痴呆症,促进痴呆症风险降低行为,并制定治疗或护理计划,以帮助成年人尽可能保持健康和独立。
