The use of lithium is well established in bipolar disorders and the benefits are
being demonstrated in neurodegenerative disorders. Recently, our group showed
that treatment with microdose lithium stabilized the cognitive deficits observed
in Alzheimer's disease (AD) patients. In order to verify the lithium microdose
potential in preventing the disease development, the aim of this work was to
verify the effects of chronic treatment with microdose lithium given before and
after the appearance of symptoms in a mouse model of a disease similar to AD.
Transgenic mice (Cg-Tg(PDGFB-APPSwInd)20Lms/2J) and their non-transgenic litter
mate genetic controls were treated with lithium carbonate (0.25mg/Kg/day in
drinking water) for 16 or 8 months starting at two and ten months of age,
respectively [corrected]. Similar groups were treated with water. At the end of
treatments, both lithium treated transgenic groups and non-transgenic mice showed
no memory disruption, different from what was observed in the water treated
transgenic group. Transgenic mice treated with lithium since two months of age
showed decreased number of senile plaques, no neuronal loss in cortex and
hippocampus and increased BDNF density in cortex, when compared to non-treated
transgenic mice. It is suitable to conclude that these data support the use of
microdose lithium in the prevention and treatment of Alzheimer's disease, once
the neurohistopathological characteristics of the disease were modified and the
memory of transgenic animals was maintained.
