The chapter reviews prior data on the relationship between homocysteine (Hcy) levels and cognitive function (such as learning, memory, and attentional processes) in various neurological disorders, including (but not limited to) mild cognitive impairment (MCI), vascular dementia, Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), as well as fibromyalgia and chronic fatigue syndrome. Specifically, we will review data showing how hyperhomocysteinemia (i.e., abnormal increase in Hcy levels) contributes to various neurological disorders. We also review prior studies showing the relationship between Hcy levels and different symptoms of MCI and AD. Further, we will discuss the neural substrates underlying the effects of Hcy levels on the brain, behavior, and cognition. Some of these brain structures include the hippocampus, cortex, as well as neurotransmitters (including acetylcholine and dopamine).
