Assessing Public Awareness of Neuropsychiatric and Cognitive Symptoms of Alzheimer's Disease in the Eastern Region of Saudi Arabia: A Cross-sectional Study.

Abstract

Objective: Alzheimer disease (AD) is the most common cause of neurodegenerative dementia; it is expected to see global cases tripling by 2050. This study evaluates public awareness of AD in the Eastern region of Saudi Arabia, highlighting the need to improve background knowledge of AD and assess the impact of public education on early detection and management.

Methodology: This study was a cross-sectional study that targeted the public in the Eastern region of Saudi Arabia. It was conducted between June 2024 and October 2024. Data were collected using an online questionnaire and analyzed using SPSS software.

Results: Our study involved 814 participants. A significant majority (94.7%) believe that brain-stimulating activities can delay AD onset. However, misconceptions persist, with 49.1% incorrectly thinking that AD can affect those in their 30s or 40s, though 86.9% correctly recognize it primarily affects those over 65 years of age. Awareness of cardiovascular health factors as risks was noted by 68.9% of participants, and 60.2% believed environmental toxins could also be a factor. Key recognized symptoms included difficulty in remembering events (76.5%), planning daily activities (65.4%), handling finances (59.7%), and confusion about time and place (79.7%). Furthermore, 80.1% understood that those with AD might better recall older events. The study also found a reliance on informal information sources, with 51.8% of participants guessing answers about the disease.

Conclusions: Many participants understand that brain-stimulating activities might delay Alzheimer's onset, but significant misconceptions regarding its typical age of onset persist. Education programs using reliable sources are crucial for improving community understanding and management of the disease.
