Abstract
Subjective cognitive decline (SCD) is prevalent in the general population, particularly among Hispanic adults. SCD increases the risk of mild cognitive impairment (MCI) and dementia. While non-pharmacologic interventions are recommended to mitigate cognitive decline and preserve daily function in SCD and MCI, such interventions are not readily available for Spanish-speaking Hispanic adults with SCD. This pilot study, preregistered at clinicialtrials.gov, aimed to develop a linguistically and culturally appropriate adaptation of an existing memory compensation intervention, the Memory Support System (MSS), from English to Spanish, and to gather data to assess its impact in this population. Twenty Spanish-speaking Hispanic adults with SCD and 16 support partners were recruited. Measures of treatment adherence, daily function, self-efficacy for memory, quality of life, mood, anxiety, and caregiver burden were assessed at baseline, treatment end, and 8-week follow-up. By treatment end, participants with SCD improved their general functional status, daily activities requiring organizational skills, and depression and anxiety symptoms. Partners reported improvement in anxiety by treatment end and in caregiver burden at follow-up. The MSS was successfully translated into Spanish and readily learned by participants with SCD and their partners. The MSS in Spanish may help with daily functioning and aspects of patient and family well-being.
Highlights
Over 20% of the general population reports subjective cognitive decline (SCD) [1], defined as cognitive concerns in the absence of objective evidence of cognitive impairment [2]
Memory Support System (MSS) training is associated with positive treatment adherence, sustained independence in IADLs, and improved memory self-efficacy for individuals with mild cognitive impairment (MCI) compared to randomized controls [8]
All 20 participants reported Subjective cognitive decline (SCD), which was corroborated by a support partner
Summary
Over 20% of the general population reports subjective cognitive decline (SCD) [1], defined as cognitive concerns in the absence of objective evidence of cognitive impairment [2]. In the absence of medications that improve cognition or delay the neurodegenerative process that often underlies SCD or MCI progression, it is considered good practice to offer non-pharmacologic interventions [3], which may help to mitigate cognitive decline and preserve daily function in SCD [5] and MCI [6]. The Memory Support System (MSS) is an evidence-based, non-pharmacologic intervention for MCI. The MSS is a calendar and notetaking system to train persons with memory or cognitive decline to complete personal goals and relevant instrumental activities of daily living (IADLs) independently [7,8]. MSS training is associated with positive treatment adherence, sustained independence in IADLs, and improved memory self-efficacy for individuals with MCI compared to randomized controls [8]. The MSS has yet to be implemented and evaluated among Spanish-speaking Hispanic adults
