BACKGROUND Olfactory deficits and executive dysfunction have been reported in Parkinson's disease (PD). However, the association between these deficits has not been thoroughly examined. METHODS We studied 44 PD subjects and 17 age-matched controls. In PD subjects, symptoms were assessed with the Unified Parkinson's Disease Rating Scale and the Hoehn and Yahr scale. Cognition in both groups wa...

Post-traumatic Olfactory Dysfunction (PTOD) consists of a complete or partial loss olfactory function that may occur after traumatic brain injury (TBI). PTOD be linked to some neuropsychiatric features, such as social, cognitive and executive dysfunction, well behavioral symptoms, especially when TBI involves the orbito-frontal cortex. The diagnosis is based on medical history clinical data it ...

BACKGROUND Olfactory dysfunction affects millions of people worldwide. This sensory impairment is associated with neurodegenerative disease and significantly decreased quality of life. Exposure to airborne pollutants has been implicated in olfactory decline, likely due to the anatomic susceptibility of the olfactory nerve to the environment. Historically, studies have focused on occupational ex...

PURPOSE To evaluate the sites of injury in patients with posttraumatic olfactory deficits and to compare damage with findings on clinical olfactory tests. METHODS Twenty-five patients with posttraumatic olfactory dysfunction were examined by means of olfactory testing, endoscopy, and MR imaging. MR surface-coil scans through the olfactory bulbs and tracts and head-coil scans of the temporal l...

Olfactory dysfunction is a common symptom associated with neurodegenerative diseases including Alzheimer's disease (AD). Although evidence exists to suggest that peripheral olfactory organs are involved in the olfactory dysfunction that accompanies AD pathology, the underlying mechanisms are not fully understood. As confirmed using behavioral tests, transgenic mice overexpressing a Swedish muta...

Results: A total of 166 patients were included in the study. The age ranged from 10 to 84 years with a mean 44.34 ± 23.059 years. Out RT-PCR positive 103 (62%) had loss taste while 114 (68.7%) smell. Nearly half subjects about 99 (51.6%) dysfunction both and smell.
 Conclusions: present study shows strong association between olfactory gustatory that COVID infection. Patients smell should b...

Mutations in CHD7, a chromodomain gene, are present in a majority of individuals with CHARGE syndrome, a multiple anomaly disorder characterized by ocular Coloboma, Heart defects, Atresia of the choanae, Retarded growth and development, Genital hypoplasia and Ear anomalies. The clinical features of CHARGE syndrome are highly variable and incompletely penetrant. Olfactory dysfunction is a common...

BACKGROUND Several studies reported olfactory dysfunction in patients with multiple sclerosis. The estimate of the incidence of olfactory deficits in multiple sclerosis is uncertain; this may arise from different testing methods that may be influenced by patients' response bias and clinical, demographic and cognitive features. AIMS To evaluate objectively the olfactory function using Olfactor...
