Abstract
Objectives: This study aimed to assess the awareness of Alzheimer’s disease (AD) and memory factors among young adults in Jeddah, Saudi Arabia, and identify associated demographic variables and gaps in knowledge.
Methods: This cross-sectional descriptive survey included 310 young adults residing in Jeddah, Saudi Arabia. Data were collected via an online self-administered questionnaire distributed through social media networks. Descriptive statistics summarized demographic characteristics, levels of awareness, knowledge about AD, and lifestyle practices related to memory enhancement.
Results: Out of 310 participants, 44.2% were unsure if memory loss is hereditary, and 64.5% believed that stress affects memory. Significant associations were found between age and knowledge about actions to strengthen memory (p-value = 0.002) and between gender and awareness of stress’ impact on memory (p-value = 0.019). The majority of participants (71.3%) understood that AD impacts memory, thinking, and behavior, yet misconceptions persisted, particularly regarding the exclusive impact of AD on the elderly.
Conclusion: The study highlighted moderate awareness levels of AD among young adults in Jeddah, with notable gaps and misconceptions. Tailored educational interventions, including age-specific and gender-sensitive programs, are recommended to improve understanding. Collaborating with healthcare professionals and caregivers and leveraging digital platforms can enhance the effectiveness of these initiatives. Future research should explore the longitudinal impacts of educational efforts to sustain improvements in AD awareness.
