This is the first time I have seen Prana scietist to talk about Zn and stroke but I my self have earlier written, that stroke most likely is an indication. The Italian study supports that we perhaps need to consider PBT2 treatment after stroke or at least Zn is important in recovery.

Zinc in the physiology and pathology of the CNS.Sensi SL, Paoletti P, Bush AI, Sekler I.

The past few years have witnessed dramatic progress on all frontiers of zinc neurobiology. The recent development of powerful tools, including zinc-sensitive fluorescent probes, selective chelators and genetically modified animal models, has brought a deeper understanding of the roles of this cation as a crucial intra- and intercellular signalling ion of the CNS, and hence of the neurophysiological importance of zinc-dependent pathways and the injurious effects of zinc dyshomeostasis. The development of some innovative therapeutic strategies is aimed at controlling and preventing the damaging effects of this cation in neurological conditions such as stroke and Alzheimer's disease.

INTRODUCTION: The objective of this study was to investigate whether zinc (Zn2+) supplementation could contribute to neurological retrieval of patients suffering from strokes and low Zn2+ intake. PATIENTS AND METHODS: Twenty-six patients with subacute stroke, having adequate daily energy (> or = 24 kcal/kg/day) and protein (> or = 0.8 g/kg/day) intake (EPI) and Zn2+ ingestion lower than two-thirds of the recommended allowance of 10 mg/day, were randomly allocated either to a control group (n = 13) or Zn2+ group (n = 13) where Zn2+ supplementation consisted of 10 mg Zn2+/day. Neurological gravity was tested with the NIH stroke scale (NIHSS) at patient admission and after 30 days of protocol commencement. RESULTS: At day 30, the improvement in NIHSS was higher in the zinc group than in the placebo (-4.7 +/- 1.3 points versus -3.3 +/- 1.1 points; P < 0.02). NIHSS and Zn2+ intake were negatively correlated (r = -0.46; P < 0.02). CONCLUSION: The normalization of Zn2+ intake in stroke patients with low mineral intake may enhance neurological recovery.
