Background: Dizziness among elderly patients is primarily treated in emergency and primary care centers. However, the causes and comorbidities responsible for dizziness in the elderly may differ in tertiary health care centers.
Objective: To determine the subtypes of persistent dizziness and to evaluate the number of contributory causes of dizziness among elderly patients.
Methods And Materials: This observational cross-sectional study comprised of 130 patients aged >60 years. A detailed history of existing comorbidities was obtained. A standardized comprehensive evaluation of all patients was done using an International Delphi procedure. Data from each patient was independently reviewed for major and contributory causes of dizziness. Chi square test was used to find the association between dizziness and various contributing factors.
Results: Presyncope was the most frequent dizziness subtype (71.5%). Majority of patients showed one dizziness subtype (54.6%) and three contributory causes of dizziness (40.6%). An adverse effect of drug was the most common contributory cause for dizziness (20%). The most frequent underlying cause of dizziness was noted to be cardiovascular disease (40%), followed by peripheral vestibular disease (22.3%) and neurological disease (19%). Sixty six percent of the patients were identified with more than one contributing cause for dizziness.
Conclusion: Primary care physicians need to anticipate that many elderly dizzy patients can have more than one cause of dizziness. A systematic and planned approach can help the clinician to effectively treat dizziness in the elderly.

Background: There are no approved oral disease-modifying treatments for Alzheimer's disease (AD).
Objectives: The objective of this study was to assess efficacy and safety of blarcamesine (ANAVEX®2-73), an orally available small-molecule activator of the sigma-1 receptor (SIGMAR1) in early AD through restoration of cellular homeostasis including autophagy enhancement.
Design: ANAVEX2-73-AD-004 was a randomized, double-blind, placebo-controlled, 48-week Phase IIb/III trial.
C-reactive protein-to-albumin ratio and systemic immune-inflammatory index as potential markers in distinguishing acute cerebellar infarction from benign paroxysmal positional vertigo.
Neurosciences (Riyadh)
January 2025
From the Department of Neurology, Faculty of Medicine, Aksaray University, Aksaray, Türkiye.
Objectives: To investigate the potential utility of the C-reactive protein-to-albumin ratio (CAR) and the systemic immune-inflammatory index (SII) as a biomarker in distinguishing between BPPV and acute cerebellar infarction (ACI) due to posterior inferior cerebellar artery (PICA) involvement.
Methods: The data of 2545 patients registered in our hospital database between 2017 and 2024 with a diagnosis of vertigo were retrospectively analyzed and 102 patients with benign paroxysmal positional vertigo (BPPV) and 100 patients with ACI were included in the study. Mann-Whitney U test, Chi-square test, or Fisher's exact test were used to compare variables between the two groups.
