Inflammation and olfactory loss are associated with at least 139 medical conditions.
Olfactory loss accompanies at least 139 neurological, somatic, and congenital/hereditary conditions. This observation leads to the question of whether these associations are correlations or whether they are ever causal. Temporal precedence and prospective predictive power suggest that olfactory loss is causally implicated in many medical conditions. The causal relationship between olfaction with memory dysfunction deserves particular attention because this sensory system has the only direct projection to memory centers. Mechanisms that may underlie the connections between medical conditions and olfactory loss include inflammation as well as neuroanatomical and environmental factors, and all 139 of the medical conditions listed here are also associated with inflammation. Olfactory enrichment shows efficacy for both prevention and treatment, potentially mediated by decreasing inflammation.
期刊介绍：
Frontiers in Molecular Neuroscience is a first-tier electronic journal devoted to identifying key molecules, as well as their functions and interactions, that underlie the structure, design and function of the brain across all levels. The scope of our journal encompasses synaptic and cellular proteins, coding and non-coding RNA, and molecular mechanisms regulating cellular and dendritic RNA translation. In recent years, a plethora of new cellular and synaptic players have been identified from reduced systems, such as neuronal cultures, but the relevance of these molecules in terms of cellular and synaptic function and plasticity in the living brain and its circuits has not been validated. The effects of spine growth and density observed using gene products identified from in vitro work are frequently not reproduced in vivo. Our journal is particularly interested in studies on genetically engineered model organisms (C. elegans, Drosophila, mouse), in which alterations in key molecules underlying cellular and synaptic function and plasticity produce defined anatomical, physiological and behavioral changes. In the mouse, genetic alterations limited to particular neural circuits (olfactory bulb, motor cortex, cortical layers, hippocampal subfields, cerebellum), preferably regulated in time and on demand, are of special interest, as they sidestep potential compensatory developmental effects.
