Hyposmia Is Associated with Reduced Cognitive Function in COVID-19: First Preliminary Results
Conclusion: OD is associated with cognitive impairment in controls and mild COVID-19. OD may represent a potentially useful clinical biomarker for subtle and even subclinical neurological involvement in severe acute respiratory distress syndrome coronavirus-2 infection.Dement Geriatr Cogn Disord (Source: Dementia and Geriatric Cognitive Disorders)

Challenges in Predicting Cognitive Decline in Dementia with Lewy Bodies
Despite being the second most common form of neurodegenerative dementia, dementia with Lewy bodies (DLB) is under-recognized and carries a worse prognosis than other subtypes of the condition. Cognitive impairment is a cardinal feature of all types of dementia and DLB presents with a distinct profile with deficits in attention, executive function, and visuoperceptual abilities. This difference from Alzheimer ’s disease and the common presence of neuropsychiatric symptoms may lead to challenges in predicting cognitive decline in this patient population. Firstly, the diagnosis of DLB is often delayed in clinical practi...

The Relationship between the Most Common Subtypes of Dementia and Orthostatic Hypotension in Older Adults
Conclusions: This study shows that elderly patients with DLB, AD, and VaD often have OH, a disabling autonomic dysfunction feature. Moreover, diastolic OH may play a role in the development of VaD. Therefore, considering potential complications of OH, it is essential to evaluate OH in the follow-up and management of those patients.Dement Geriatr Cogn Disord (Source: Dementia and Geriatric Cognitive Disorders)
