APOE-4 Anti-Dementia Facebook Live Tips! | Facebook Live with Dan Purser MD

APOE encodes a protein that carries lipids between cells. The familiar APOE e2, e3 and e4 groupings depend on the combination of rs429358 and rs7412, not on either marker read in isolation.

Follow Dr. Purser’s teaching on folate, B12, sulfur pathways and antioxidant support around homocysteine.

NTRK2 encodes TrkB, a receptor involved in responding to neurotrophic signals such as BDNF. These signals support nervous-system function and plasticity. NTRK2 is not a phosphatidylserine absorption transporter.

PSEN1 encodes a presenilin protein that participates in gamma-secretase, a protein-processing complex. Some pathogenic variants can cause familial Alzheimer’s disease; a listed common marker is not equivalent to that diagnosis.
