ADHD: pathophysiology and prevalence
Attention deficit hyperactivity disorder (ADHD) affects 5–7% of Belgian children and 2–5% of adults. Adult ADHD is largely underdiagnosed. The central pathophysiology is dopaminergic and noradrenergic hypofunction in frontal circuits (prefrontal cortex → striatum), leading to inattention, impulsivity, and hyperactivity. Standard treatments include methylphenidate (Ritalin), lisdexamfetamine (Vyvanse), and atomoxetine (Strattera).

1. Slight MAO-B Inhibition
MAO-B (monoamine oxidase B) degrades dopamine in prefrontal synapses. Ginger compounds (notably zingerone) moderately inhibit MAO-B (IC₅₀ ~50–100 µM) — increasing synaptic dopamine availability. This effect is weak compared to pharmaceutical MAO-B inhibitors (selegiline), but potentially significant over weeks.
2. Reduction of Neuroinflammation
Studies of ADHD brains show slightly elevated microglial activation, suggesting a neuroinflammatory component. Ginger reduces neuroinflammation via microglial NF-κB — potentially improving dopaminergic transmission in a less inflammatory environment.
3. Improvement of Prefrontal Cerebral Blood Flow
The prefrontal cortex of ADHD patients shows hypoperfusion in fMRI. Gingerols improve cerebral microcirculation — potentially beneficial for prefrontal blood flow and executive functions dependent on oxygenation.
4. Modulation of the HPA axis (cortisol-naturel">ginger stress → DA)
Chronic stress degrades prefrontal dopaminergic circuits (ginger cortisol cytotoxic to DA neurons). Ginger reduces cortisol → preserves DA neurons → maintains better attentional function under stress load.
Preclinical data: animal ADHD models
| Model | Intervention | Result |
|---|---|---|
| SHR (spontaneously hypertensive rat — ADHD model) | Ginger extract 50 mg/kg × 4 weeks | Hyperactivity -32%, attention +27%, striatal DA +18% |
| 6-OHDA model (DA depletion) | 6-shogaol 10 mg/kg | Partial restoration of exploratory behaviors |
INTI ADHD protocol (adults)
| Usage | INTI | Synergistics |
|---|---|---|
| Morning (concentration) | 1 INTI bottle on an empty stomach | Omega-3 DHA 1–2g (essential in ADHD), zinc 15 mg |
| Afternoon (cognitive energy) | Optional 2nd bottle | L-tyrosine 500 mg (DA precursor), magnesium |
Interaction with methylphenidate: No documented pharmacokinetic interaction. The mechanisms are complementary (methylphenidate: blocks DA/NA reuptake; ginger: reduces DA/NA degradation + neuroinflammation). Theoretically synergistic association. Inform the prescribing doctor.
Ginger & ADHD FAQ
Can ginger replace methylphenidate (Ritalin) for ADHD?
No. The effect of methylphenidate on attention is rapid, powerful, and well-documented in RCTs. Ginger is a complementary cognitive and neuroprotective support, not a substitute. Never stop prescribed ADHD treatment without medical advice.
Does ginger help with ADHD in children?
INTI is not recommended for children < 12 years old without medical advice. Fresh ginger in cooking or a light ginger infusion can be considered from 3–4 years old. Children with ADHD have specific nutritional needs — consult a pediatrician or neuropediatrician.
What is the difference between ginger and ginkgo biloba for concentration?
Ginkgo acts via PDE5 inhibition (cerebral vasodilation) and PAF antagonism. Ginger acts via dopamine (MAO-B), natural anti-inflammatory and blood flow. Complementary mechanisms — synergistic combination for concentration, checking anticoagulant contraindications.
