Abstract:

AbstractBackground:Olfactory disorders increase with age and often affect elderly people who have pre-dementia or dementia. Despite the frequent occurrence of olfactory changes at the early stages of neurodegenerative disorders such as Alzheimer's disease, olfactory disorders are rarely assessed in daily clinical practice, mainly due to a lack of standardised assessment tools. The aims of this review were to (1) summarise the existing literature on olfactory disorders in ageing populations and patients with neurodegenerative disorders; (2) present the strengths and weaknesses of current olfact

Abstract:

The receptor cells in the olfactory neuroepithelium are regularly replaced and, when injured, regenerate from basal cells and reestablish their central connections. This process of reconstitution occurs throughout the life span after mechanical, chemical, and infectious injury. The history and physical findings in association with the quantification of the olfactory loss allow an etiologic diagnosis in many patients. Olfactory losses can be categorized as transport or sensorineural defects. Therapy for transport olfactory losses is frequently effective in restoring the sense of smell. Reasonab

Abstract:

Since the outbreak of the SARS-CoV-2 pandemic, olfactory disorders have been reported as a frequent symptom of COVID-19; however, its pathogenesis is still debated. The aim of this review is to summarize the current understanding of the pathogenesis of smell impairment in the course of COVID-19 and to highlight potential avenues for future research on this issue. Several theories have been proposed to explain the pathogenesis of COVID-19-related anosmia, including nasal obstruction and rhinorrhea, oedema of the olfactory cleft mucosa, olfactory epithelial damage either within the olfactory rec

Abstract:

Abstract Olfactory dysfunction (OD) is a common nonmotor symptom observed in several movement disorders. The severity and pattern of olfactory impairment vary among these conditions. Notably, olfactory impairment often precedes the clinical diagnosis of movement disorders by several years, yet it remains frequently unrecognized by patients and physicians until formal olfactory tests are undertaken. This review focuses on exploring OD across various movement disorders. A systemic search strategy incorporating key terms such as movement disorders, dystonic disorders, tic disorders, parkinsonian

It is known that olfactory dysfunction occurs early in neurodegenerative diseases, such as Alzheimer’s and Parkinson’s diseases and frontotemporal dementia (FTD). Dementia and psychiatric disorders share a number of clinical features, such as psychosis and depression. As such, misdiagnoses across these conditions are not uncommon. A variety of studies show smell dysfunction in schizophrenia, but little is known about other psychiatric disorders.

Olfactory dysfunction appears to be one of the earliest signs of several age-related neurodegenerative disorders, including Alzheimer`s disease (AD) or Parkinson`s disease (PD).

Abstract:

Olfactory dysfunction is considered a pre-cognitive biomarker of Alzheimer’s disease (AD). Because the olfactory system is highly conserved across species, mouse models corresponding to various AD etiologies have been bred and used in numerous studies on olfactory disorders. The olfactory behavior test is a method required for early olfactory dysfunction detection in AD model mice. Here, we review the olfactory evaluation of AD model mice, focusing on traditional olfactory detection methods, olfactory behavior involving the olfactory cortex, and the results of olfactory behavior in AD model mi

Abstract:

The problem of the occurrence of persistent olfactory dysfunction (OD) associated with Novel Coronavirus infection (COVID-19) has now become relevant, however, a regulated standard of therapy has not been developed. According to the literature, about 60 % of patients report the presence of olfactory disorders that persist for several months or more after recovery from COVID-19. However, no more than 5 % seek medical help for olfactory disorders, which indicates the importance of the problem and the need for treatment in a polyclinic setting. Currently, two main areas of treatment for quantitat

Introduction. Modern algorithms for the diagnosis and treatment of allergic rhinitis (AR) recommend a stepwise approach for managing symptoms of the disease. A part of patients with AR have symptoms that indicate to the past COVID-19 followed by significant impairment of the olfactory function. The article places special emphasis on the intranasal glucocorticosteroid option of treatment to manage nasal and general symptoms in persistent AR.The aim of the study is to evaluate the efficacy of mometasone furoate in patients with a confirmed diagnosis of persistent AR, olfactory disorders, and pas

Abstract:

Background: Changes in olfactory recognition memory may constitute sensory markers in depression. Significant differences may exist between unipolar and bipolar depression. Our study compares olfactory memory between control, unipolar, and bipolar patients in depressed and euthymic states in order to identify potential markers of depression. Methods: 176 participants were recruited in 5 groups: depressed bipolar (DB), euthymic bipolar (EB), depressed unipolar (DU), euthymic unipolar (EU), and controls (HC). The participants had a standardized clinical and olfactory assessment (olfactory memory

Abstract:

The ability to scrutinize our surroundings remains heavily dependent on the sense of smell. From the ability to detect dangerous situations such as fires to the recollection of a fond memory triggered by an odor, the advantages of an intact olfactory system cannot be overstated. Outcomes studies have highlighted the profound negative impact of anosmia and parosmia on the overall quality of life. The National Institute on Deafness and Other Communication Disorders estimates that ∼1.4% of the United States population experiences chronic olfactory dysfunction and smell loss. Efforts have focused

Abstract:

Olfactory studies can be a criterion for evaluating rhinosurgical intervention, and olfactory impairment may indicate respiratory impairment. Therefore, the urgent task is to develop an integrated approach to determining respiratory and olfactory disorders. A structural scheme was developed for the method of objective diagnosis of respiratory and olfactory disorders, taking into account the measu, rement of both the aerodynamic parameters of nasal breathing and the calculation of energy characteristics, which are used to determine olfactory sensitivity.

Abstract:

The human sense of smell is important for many vital functions, but with the current state of the art, there is a lack of objective and non-invasive methods for smell disorder diagnostics. In recent years, increasing attention is being paid to olfactory event-related potentials (OERPs) of the brain, as a viable tool for the objective assessment of olfactory dysfunctions. The aim of this review is to describe the main features of OERPs signals, the most widely used recording and processing techniques, and the scientific progress and relevance in the use of OERPs in many important application fi
