Will your competent? doctor ensure human testing gets done? Or has the board of directors incompetence let your stroke medical 'professionals' DO NOTHING that will further stroke recovery? You'll need this because of your elevated chance of dementia.
Do you prefer your doctor and hospital incompetence NOT KNOWING? OR NOT DOING?

Abstract
Impaired adult hippocampal neurogenesis is a key pathological
mechanism contributing to memory deficits in Alzheimer's disease (AD).
Recent studies have shown that elevating magnesium levels promotes
neurogenesis by enhancing the neuronal differentiation of adult neural
progenitor cells in vitro. Therefore, this in vivo study aims to
determine if magnesium-L-threonate (MgT) can ameliorate cognitive
deficit of AD mice by attenuating adult hippocampal neurogenesis
impairment and to reveal the underlying mechanisms. APPswe/PS1dE9 mice
were treated with different doses of MgT and ERK inhibitor PD0325901.
The memory ability of each mouse was recorded by Morris Water Maze test.
After cognitive test, hippocampus tissues were collected to measure the
proportion of BrdU/doublecortin double-labeled cells using the flow
cytometry test and assess the expression of doublecortin using PCR and
Western blot. Furthermore, the activations of CREB, ERK, P38 and JNK
were measured by Western blot to identify the involved mechanisms. The
cognitive test confirmed that MgT treatment attenuated the memory
impairment of APPswe/PS1dE9 mice. Flow cytometry test showed that
Brdu/doublecortin labeled newborn neurons gradually increased following
MgT administration. In line with the flow cytometry results, Western
blot and PCR confirmed that MgT administration significantly increased
doublecortin expression levels. Furthermore, the ratios of p-ERK/ERK and
p-CREB/CREB increased with MgT elevation. In addition, these effects of
MgT treatment were markedly reversed by PD0325901 supplementation. In
conclusion, MgT treatment improved cognitive decline by ameliorating
adult hippocampal neurogenesis impairment in this AD model, possibly via
ERK/CREB activation.
