Olfaction in Parkinson's disease and related disorders [PDF]

Neurobiology of Disease, 2012
Olfactory dysfunction is an early ‘pre-clinical’ sign of Parkinson's disease (PD). The present review is a comprehensive and up-to-date assessment of such dysfunction in PD and related disorders. The olfactory bulb is implicated in the dysfunction, since

Frontiers in Psychology, 2015
The study provides a systematic review that explores the current literature on olfactory capacity in abnormal eating behavior to present a basis for discussion on whether research in olfaction in eating disorders may offer additional insights with regard

Olfaction: A potential cognitive marker of psychiatric disorders [PDF]

Neuroscience & Biobehavioral Reviews, 2008
Cognitive deficits are well documented in psychiatric disorders, particularly in schizophrenia and depression. Cognitive activity roots in perceptions. However, research on sensorial alterations in psychiatric conditions has mainly focused on visual or auditory processes and less on olfaction.

The impact of nicotine on the olfactory memory and its relationship with TRPA1 [PDF]

iScience
Summary: Olfactory disorders are related to cognitive decline, yet effective treatments remain limited. Cigarette smoke impairs olfaction, but one of its components, nicotine, can protect nerve cells in the central nervous system.

Modulation of Higher-Order Olfaction Components on Executive Functions in Humans. [PDF]

PLoS ONE, 2015
The prefrontal (PFC) and orbitofrontal cortex (OFC) appear to be associated with both executive functions and olfaction. However, there is little data relating olfactory processing and executive functions in humans.

Olfaction, psychiatric disorders and autoimmunity: Is there a common genetic association?

Autoimmunity, 2009
Psychiatric diseases are often associated with mild alterations in immune functions (e.g., schizophrenia) as well as autoimmune features. Recent evidence suggests that autoimmune diseases (AD) demonstrate a higher prevalence of psychiatric disorders, such as depression and psychosis, than in the normal population.

The mysterious sense of smell: evolution, historical perspectives, and neurological disorders [PDF]

Frontiers in Human Neuroscience
Phylogenetically, the chemical sense of smell is the oldest of all sensory modalities in terrestrial and aquatic organisms. For most non-human species in the wild, it is essential like other senses for survival because it aids nutrition, detection of ...

Depression, Olfaction, and Quality of Life: A Mutual Relationship

Brain Sciences, 2018
Olfactory dysfunction has been well studied in depression. Common brain areas are involved in depression and in the olfactory process, suggesting that olfactory impairments may constitute potential markers of this disorder.

The Olfactory System: Basic Anatomy and Physiology for General Otorhinolaryngologists [PDF]

Clinical and Experimental Otorhinolaryngology, 2023
Olfaction is one of the five basic human senses, and it is known to be one of the most primitive senses. The sense of olfaction may have been critical for human survival in prehistoric society, and although many believe its importance has diminished over
