Story summary

USC researchers created the Cerebrovascular Dynamics Index (CDI), a non-invasive tool for diagnosing Alzheimer’s by measuring brain blood flow and oxygen regulation.
The CDI achieved 96% accuracy in differentiating mild cognitive impairment from healthy individuals, surpassing traditional tests.
A study found a toxic protein complex linked to neuron death in Alzheimer’s, with the drug FP802 showing potential in mice.
These studies emphasize new methods for early Alzheimer’s diagnosis and treatment, impacting over seven million Americans.
