Summary
Biometal and environmental metal ion imbalances are linked to Alzheimer's disease (AD) pathology, specifically affecting amyloid and tau aggregation. This review explores how these metal ions influence AD progression.
Area of Science:
- Neuroscience
- Biochemistry
- Environmental Health
Background:
- Alzheimer's disease (AD) is characterized by amyloid and tau aggregation.
- Aging is a risk factor, but biometal ion imbalance and environmental metal exposure also contribute to AD.
- Metal ions are vital but toxic in excess or deficiency, impacting neurotoxicity.
Purpose of the Study:
- To review the role of endogenous and exogenous metal ions in Alzheimer's disease.
- To elucidate the mechanisms by which metal ions affect amyloid and tau pathology.
- To synthesize current research on metal ion dyshomeostasis in AD pathogenesis.
Main Methods:
- Literature review of existing studies on metal ions and AD.
- Analysis of research linking biometal dyshomeostasis to neurodegeneration.
- Examination of studies on environmental metal exposure and AD pathology.
Main Results:
- Biometal ion dyshomeostasis is associated with neurotoxic alterations in AD.
- Environmental metal ions can mediate and exacerbate AD pathogenesis.
- Both endogenous and exogenous metal ions impact amyloid and tau aggregation.
Conclusions:
- Metal ion dyshomeostasis is a significant factor in Alzheimer's disease.
- Environmental exposure to metals poses a risk for AD development and progression.
- Further research is needed to understand the precise roles of various metal ions in AD.

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

In ordinary chemical reactions, the nucleus — which contains the protons and neutrons of each atom and thus identifies the element — remains unchanged. Electrons, however, can be added to atoms by transfer from other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons to form electrically charged particles called...
