A study from The Journal of Trace Elements of Medicine and Biology concluded that aluminum was found in the brain tissue of patients with Alzheimer’s disease. While they propose not to know the cause, they do admit that doses of aluminum were extremely high in 12 patients with Alzheimer’s disease.

Aluminum in Brain Tissue of Familial Alzheimer’s disease.

Here’s the conclusion of the study.

5. Conclusions

Aluminium is neurotoxic [11,23] and the concentrations of aluminium found in these familial AD brains are unlikely to be benign and indeed are highly likely to have contributed to both the onset and the aggressive nature of any ongoing AD in these individuals. These data lend support to the recent conclusion that brain aluminium will contribute towards all forms of AD under certain conditions [15].
