Alzheimer’s disease and related dementias present a significant public health challenge in Spain, affecting an estimated 800,000 people, which represents 60% to 70% of dementia cases. The disease disproportionately affects women; for instance, regional data from the Canary Islands indicates that 72.2% of those affected are women. The burden on families remains high, with studies showing that nearly half of the Spanish population has cared for someone with the condition. In observance of World Alzheimer’s Day, medical experts and organizations are emphasizing that pathological brain changes can begin approximately 20 years before clinical symptoms appear. Recent developments in diagnostic capabilities include the emergence of blood-based biomarkers, such as the p-tau217 protein, which may allow for more precise and earlier detection of biological changes. In Germany and Austria, research is specifically focusing on early detection through blood and cerebrospinal fluid biomarkers to identify brain changes years before symptoms manifest. In Spain, the Spanish Confederation of Alzheimer's (CEAFA) continues to campaign for public health system funding for newly authorized European treatments, lecanemab and donanemab, which can slow disease progression in early stages. This follows reports that approximately 40,000 new cases are diagnosed annually in Spain, with over 65% of those being women. Broader European trends reflect a growing crisis. In Italy, health officials have described the situation as a public health emergency, noting that dementia cases are expected to rise significantly by 2050. In Slovenia, 47,000 people currently live with dementia. Global efforts are increasingly emphasizing caregiver support and lifestyle interventions, such as social and physical activity, to help delay symptom onset. As World Alzheimer’s Day approaches, the scale of the global crisis is being underscored by the World Health Organization, which reports that over 57 million people currently live with dementia, with 10 million new cases diagnosed annually.
