BACKGROUND Olfaction dysfunction is linked to neurodegenerative diseases, therefore the evaluation of this function is becoming important AIM To evaluate olfaction in healthy participants. MATERIAL AND METHODS We evaluated 44 healthy males and 55 females, aged 21 to 89 years with the Sniffing Sticks battery to determine normal values in Chilean population. During the test, participants must...

BACKGROUND We evaluated smell identification as a biomarker for Alzheimer disease (AD) by assessing its utility in differentiating normal aging from an amnestic disorder and determining its predictive value for conversion from amnestic mild cognitive impairment (aMCI) to AD. METHODS Cross-sectional study (AD = 262, aMCI = 110, controls = 194) measuring smell identification (University of Penn...

Taste and smell alterations have been recognized as common symptoms in relation to various cancers. However, previous research suggests that patients do not receive sufficient support in managing taste and smell alterations. Therefore, the objective of this study is to investigate how persons with experience from lung cancer-related taste and smell alterations reason about resources and strateg...

OBJECTIVES To study the long-term results of the nasal airflow-inducing maneuver (NAIM) as an olfaction rehabilitation tool after laryngectomy and to investigate the effectiveness of a new, simpler odor detection test (ODT) called the smell disk test (SDT), or Zürcher Geruchstest. DESIGN Intervention study. SETTINGS National cancer center. PATIENTS Forty-one laryngectomees who received ol...

BACKGROUND Anatomy professors world over are lamenting about medical students' lack of interest in dissections and its diminishing utilisation in medical studies. The objective of our study was to find out the reasons why some of the Pakistani medical students were avoiding dissections. METHOD We conducted this study in 5 medical colleges of Pakistan from Dec 2010-Oct 2011. Questionnaires wer...

Sleep is an indispensable normal physiology of the human body fundamental for healthy functioning. It has been observed that Parkinson's disease (PD) not only exhibits motor symptoms, but also non-motor symptoms such as metabolic irregularities, altered olfaction, cardiovascular dysfunction, gastrointestinal complications and especially sleep disorders which is the focus of this review. A good ...

This review summarizes neuroimaging findings in patients with olfactory dysfunction. Neuroimaging techniques offer a valuable means for evaluating and distinguishing disorders of olfaction. The new or refined techniques make it possible to pinpoint the anatomic and pathologic changes of many disorders of the sinonasal cavity and brain that cause olfactory deficits. From an anatomic point of vie...
