Neuroscience and heart-brain medicine: the year in review.

Cleveland Clinic Journal of Medicine

Abstract

Important recent publications in the area of neuroscience and heart-brain medicine center largely around three topics: (1) mechanisms of cardiac sympathetic denervation in Parkinson disease, (2) cytoplasmic monoamine metabolites as autotoxins, and (3) the validity of power spectral analysis of heart rate variability to indicate cardiac sympathetic tone. Findings by Orimo et al support a centripetal, retrograde pathogenetic process involving alpha-synuclein deposition and degeneration of cardiac noradrenergic neurons in Parkinson disease. Several studies suggest that processes increasing cytoplasmic monoamines lead to neuronal loss from auto-oxidation or enzymatic oxidation. Lack of correlation between commonly used indices from power spectral analysis of heart rate variability and cardiac norepinephrine spillover casts doubt on the validity of power spectral analysis to indicate cardiac sympathetic tone.

Alpha-Synuclein Aggregation (MDS)

Alpha-synucleins are small proteins that are believed to restrict the mobility of synpatic vesicles and inhibit neurotransmitter release. Aggregation of these proteins have been linked to several types of neurodegenerative diseases including dementia with Lewy bodies and Parkinson's disease. Here is the latest research on α-synuclein aggregation.
