Scientists have identified new ways lithium chloride may interact with Alzheimer’s disease mechanisms at the cellular level.

A new study from the University of Eastern Finland (UEF) suggests lithium chloride may influence several cellular processes linked to Alzheimer’s disease.

Alzheimer’s disease (AD) is the most common type of dementia. One of its key features is the abnormal phosphorylation and buildup of Tau proteins inside brain cells, along with the accumulation of β-amyloid (Aβ) plaques.

Researchers have previously used lithium salts, especially lithium chloride and lithium carbonate, in cell and animal models of AD to reduce Tau hyperphosphorylation and aggregation. However, human clinical trials have produced inconsistent results, with some studies showing little or no improvement in cognitive function.
