According to NCBI, “Zinc deficiency may affect cognitive development by alterations in attention, activity, neuropsychological behavior and motor development.”  Zinc is severely depleted following a traumatic brain injury and zinc supplementation might improve the outcomes of traumatic brain injury (TBI).  Clinical trials  have concluded that zinc provides behavior resiliency against TBI.  Additionally, zinc supplementation has shown to positively improve cognitive behavior in TBI victims, as well as TBI-induced depression and anxiety.  Furthermore, zinc was also shown to be effective at preventing impaired spatial learning and memory, both crucial to the recovering of a brain injury.
