Ginger and Alzheimer's Disease: Neuroinflammation, Tau & Amyloid

Alzheimer's: Neuroinflammation as an accelerator

Alzheimer's disease affects 150,000 people in Belgium. Two characteristic lesions: amyloid plaques (Aβ) and neurofibrillary tangles (hyperphosphorylated Tau). Chronic neuroinflammation (activated microglia) is now recognized as a key accelerator—not just a consequence. NSAIDs have shown protective effects in epidemiological prevention studies. Ginger, with its anti-neuroinflammatory profile, is a natural alternative worth exploring.

Neuroprotective mechanisms of ginger

1. Inhibition of microglial neuroinflammation

Hyperactivated microglia produce IL-1β, TNF-α, and NO that enhance neuronal death. Gingerols → microglial inflammation-mecanisme-cle-ginger-sugar-explanation-2026">NF-κB↓ → neuroinflammation↓. Hippocampal IL-1β ↓40% in Alzheimer's mouse models after 8 weeks.

2. Reduction of β-amyloid aggregation

In vitro, gingerols (6- and 8-gingerol) inhibit the aggregation of Aβ1-42 peptides and promote disaggregation. Documented in biophysical studies but not yet translated to human clinical studies.

3. Reduction of Tau phosphorylation

Hyperphosphorylated Tau protein forms destructive neurofibrillary tangles. Ginger extract inhibits GSK-3β and CDK5 (kinases responsible for pathological Tau phosphorylation) — reducing by 35–50% in cell models.

4. BDNF increase in hippocampus

BDNF is drastically reduced in the hippocampus of Alzheimer's patients. Ginger promotes BDNF synthesis through reduced neuroinflammation and Nrf2 activation — contributing to neuroplasticity.

INTI protocol for cognitive prevention

• Primary prevention (50+, family history): 1–2 INTI shots per day continuously
• Cognitive support: 2 shots per day, integrate into overall approach (exercise, Mediterranean diet, cognitive stimulation)
• Neuroprotective synergies: Omega-3 DHA (neuronal membrane), curcumin (Aβ inhibition), vitamin E, resveratrol
