In 2026, there are at least 7 reasons to be hopeful about dementia research, according to The Washington Post.
1. FDA-approved blood test for early detection (90%+ accuracy)
2. New drug delivery tech crossing the blood-brain barrier
3. First successful gene therapy for Huntington's disease
4. Focus on inflammation opening new treatment paths–including research from the Global Neurodegeneration Proteomics Consortium HDS v1, showing how APOE4 triggers immune system changes linked to Alzheimer's risk
5. Shingles vaccines linked to slowing dementia progression
6. Lifestyle interventions improving cognition
7. Lithium showing neuroprotective potential
This is what happens when research comes together.
