Summary
Smell loss is an early sign of neuropsychiatric disorders. Research links olfactory deficits to these conditions, offering potential for early detection and new treatments.
Area of Science:
- Neuroscience
- Olfactory research
- Neuropathology
Background:
- Smell deficits are early clinical indicators of neuropsychiatric disorders.
- Olfactory dysfunction has gained research attention, particularly post-COVID-19.
- Understanding the olfactory system's role in health and disease is crucial.
Approach:
- Review of human clinical studies correlating smell deficits with neuropsychiatric disorders.
- Analysis of olfactory mucosa-derived tissue and cell models for molecular pathology.
- Examination of brain imaging studies on olfactory pathway connectivity changes.
- Evaluation of preclinical animal models for validating human findings.
Key Points:
- Strong evidence links the olfactory system to neuropsychiatric disorders.
- Olfactory deficits serve as potential early biomarkers.
- Molecular and neuroimaging studies reveal neuropathological mechanisms.
- Animal models support human findings and explore therapeutic avenues.
Conclusions:
- Deepening understanding of the olfactory system is vital for neuropsychiatric research.
- Future research may enable early detection of neuropsychiatric disorders.
- Nasal administration techniques offer potential for personalized treatments.

01:03Olfactory Receptors: Location and Structure
9.3K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

8.6K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
