Alzheimer Detection: NITROGEN AI Predicts Disease with 92% Accuracy!

In 2021, 57 million people were affected worldwide, with an additional 10 million new cases each year. The costs? About 1.134 trillion euros annually. It’s no wonder that researchers and health policymakers are focusing on prevention and early detection.

NITROGEN: AI Predicts Alzheimer’s with 92% Accuracy

A breakthrough emerges from Texas. Researchers at Texas A&M University have developed “NITROGEN” – a transformer-based AI system that analyzes data from approximately 10,000 patients. This system identifies Alzheimer’s disease with over 92% accuracy, sometimes up to seven years before initial symptoms appear.

Moreover, biomarkers such as p-tau217 show promising results: high levels indicate a 78% risk of developing Alzheimer’s within the next ten years. Initial testing methods have already been approved for p-tau217 and ß-amyloid in May 2025, followed by additional approvals in October.

WHO: 45% of Dementia Risk is Preventable

In July 2026, the World Health Organization (WHO) updated its guidelines. The main message: up to 45% of dementia risk can be influenced by lifestyle changes. Exercise tops the list, with the WHO recommending 150 to 300 minutes of moderate activity per week. For those over 40, twice-weekly muscle training is also advised.

However, exercise alone is not sufficient. The WHO identifies additional factors:

• Diet: Mediterranean diet, cessation of smoking, and reduced alcohol intake. Vitamin or Omega-3 supplements are ineffective unless there’s a proven deficiency.
• Medical Check-ups: Managing hypertension, diabetes, obesity, and hearing loss can significantly reduce dementia incidence.
• Social and Cognitive Engagement: Increased social participation and cognitive stimulation through reading or games is now explicitly recommended. Reducing exposure to air pollutants also helps.

7,000 Steps Daily: Movement Protects the Brain

Recent science becomes more concrete. A July 2026 study published in Nature Medicine involving 88 subjects found that walking just 3,000 steps daily can slow progression in the preclinical stage. Better results come from 5,000 to 7,500 steps per day. Regular movement promotes growth factors and slows the spread of Tau protein.

Meta-analyses from 2025 reaffirm this trend: approximately 7,000 steps per day significantly lower dementia risk. Initiatives such as the Freiburg “ReduRisk” program have demonstrated measurable cognitive improvements in people over 70 through targeted mobility training.

Medications: SGLT2 Inhibitors Reduce Alzheimer’s Risk by 43%

Up to 45% of all dementia cases are preventable through lifestyle changes, according to the WHO. But which measures truly work? The report summarizes current research findings: from walking 7,000 steps daily to a Mediterranean diet and novel biomarker tests.

Pharmaceutical companies are also exploring promising approaches. SGLT2 inhibitors and GLP-1 agonists could lower Alzheimer’s risk by 43% and 33%, respectively. Roche plans a Phase III study named “PrevenTRON” involving 1,600 symptom-free participants aged 55 and older. New substances like Trontinemab and Diranersen will undergo testing, with the latter aiming to reduce tau fibrils by 50-65% and potentially slow cognitive decline by up to 42%.

The numbers are stark: annual care costs range between €50,000 and €70,000 per patient. Germany allocated €734 million for health promotion in 2025, which includes initiatives like the “Check-up 60 plus”. The goal is to identify risk factors early, before the disease manifests.
