- Pharmacogenetic randomized trial for cocaine abuse: disulfiram and dopamine ÎČ-hydroxylase
PubMed ID: 22906516
Pharmacogenetic trial implicates dopamine ÎČ-hydroxylase (a copper-dependent enzyme) in disulfiram response, linking copper biology to neurotransmitter metabolism and brain effects.

- A study of susceptibility-weighted imaging in patients with Wilson disease during the treatment of metal chelator
PubMed ID: 32060651
Wilson disease chelation regimens improved neurological scores and normalized brain metal signals over time â clear link between copper biology and nervous system function (in disease context).
- Treatment of Wilson disease with ammonium tetrathiomolybdate: IV. Comparison of tetrathiomolybdate and trientine in a double-blind study of treatment of the neurologic presentation of Wilson disease
PubMed ID: 16606763
Wilson disease trial: copperâmodulating therapy (tetrathiomolybdate) produced better neurologic outcomes than trientineâshows that copper balance critically affects neurologic function (dysregulation rather than supplementation).
- Pharmacogenetic randomized trial for cocaine abuse: disulfiram and dopamine ÎČ-hydroxylase
PubMed ID: 22906516
DÎČH (copper-dependent) genotype strongly influenced disulfiram response in cocaine use disorder â links copper enzyme activity to nervous-system outcomes.

PubMed ID: 8027856
Calcium plus trace minerals (including copper) increased spinal bone density versus placebo; copper included in beneficial mix.
- [Vitrum osteomag in prevention of osteoporosis in postmenopausal women: results of the comparative open multicenter trial]
PubMed ID: 15658548
Multinutrient supplement containing copper produced modest increases in lumbar spine and proximal hip BMD in postmenopausal women; copper part of combined intervention.

PubMed ID: 33568038
Oral multiâingredient supplement (includes copper) plus exercise produced greater durable pain/disability improvements versus exercise aloneâcopper contribution uncertain but supportive signal.
Mood balance (1)
- Zinc Therapy in Mild Cognitive Impairment: Cognitive Stabilization in Pharmacodynamically Responsive Patients in the ZINCAiD Trial
PubMed ID: 41008575
