Activitatea cerebrală ar putea indica riscul de Alzheimer cu până la 12 ani înaintea apariţiei simptomelor

Brain activity changes may help identify individuals at high risk for Alzheimer's disease up to 12 years before symptoms appear. Researchers from Stanford Medicine found specific communication patterns in the brain linked to cognitive decline and preservation of cognitive abilities in older adults. Using functional MRI, they analyzed brain connectivity and developed the ARC system to assess cognitive resilience. The study showed that individuals with brain patterns similar to Alzheimer's patients experienced faster cognitive decline, while those resembling 'SuperAgers' had slower decline. The ARC system demonstrated predictive capabilities comparable to existing biomarkers, highlighting the potential for early intervention.
