In Germany, approximately 1.8 million people are currently diagnosed with Alzheimer’s disease, with projections indicating this figure could rise to 2.7 million by 2050. Experts suggest that nearly half of dementia cases could be prevented through targeted measures. The landscape of Alzheimer’s treatment is evolving, especially with the introduction of two novel antibody therapies, Lecanemab and Donanemab, available from June 2026. These treatments aim to reduce amyloid plaques in the brain, a hallmark of Alzheimer’s disease, and are expected to benefit around 120,000 of the 1.2 million patients in Germany.
Old Medications, New Discoveries
Interestingly, research is uncovering unexpected potential in established medications. SGLT2 inhibitors, originally developed for diabetes management, have shown a 43% reduction in Alzheimer’s risk. Similarly, GLP-1 agonists have demonstrated a risk reduction of 33%. Even a vaccine for shingles, Shingrix, has been linked to a 24% decrease in dementia risk according to a study conducted by Brown University.
The Role of AI in Early Detection
Early recognition of Alzheimer’s is becoming increasingly critical. The annual progression rate from mild cognitive impairment to dementia is about 15.7%. Innovative technologies are emerging that can identify risks long before symptoms manifest. AI-driven models based on retina scans can predict Alzheimer’s risk up to 8.55 years in advance. The market for such technology is rapidly expanding, projected to grow from $2.65 billion in 2023 to an astounding $9.4 billion by 2033.
Blood tests from companies like Roche and Eli Lilly are also showing promise, achieving over 90% accuracy by identifying biomarkers such as pTau217. However, despite these advancements, a significant diagnostic gap persists. It’s estimated that about 60% of dementia patients in Germany have not received a specialist diagnosis, and this figure is around 50% in Switzerland for the annual influx of 30,000 new cases.
The new antibody therapies offer hope, but not all patients will qualify for these treatments. To better understand individual risks and how to mitigate them through lifestyle changes, consider reaching out for a free guide that details these methods, which can potentially lower risk by up to 30%.
Lifestyle as Medicine
Researchers are increasingly focusing on modifiable risk factors associated with dementia. For example, using hearing aids can reduce dementia risk by 23%, and an anti-inflammatory diet may lower it by 30%. Social interactions, physical activity, and mental challenges are also critical pillars of prevention.
An often-overlooked factor is oral health. A study involving over 90,000 participants from the US cohort “All of Us” revealed that financial barriers to dental care could increase the risk of dementia and cardiovascular diseases. It’s estimated that 2 to 4% of such cases could be preventable if access to dental care were improved.
Conversely, certain medications pose an increased risk. Anticholinergics elevate the risk by 54%, while proton pump inhibitors increase it by 44%.
Calls for Better Data Structure in Policy
The annual costs associated with dementia exceed €80 billion. Academies, including Leopoldina and Acatech, are advocating for a realignment of preventive strategies. In statements issued in Spring 2026, experts emphasized the urgent need for data-driven prevention strategies.
One key recommendation is the introduction of a digital unique identifier. This would securely link health data and facilitate the creation of personalized risk profiles.
With almost 60% of dementia patients without a diagnosis, AI retina scans can identify risks up to 8.5 years before symptoms appear. Emphasizing the importance of early detection and simple lifestyle modifications could slow the disease’s progression. A national research app is in the works, which will use digital biomarkers to identify cognitive decline earlier and slow progression through targeted interventions by up to 25%.
For awareness, regional informational events are regularly organized. There is an open house day dedicated to dementia prevention in Wunstorf today, with a screening day for seniors scheduled in Bad Rodach for September 2026.
