Journal of Clinical Ultrasound, EarlyView.This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Metabolic Syndrome and Dementia Risk in Older Adults: A Narrative Review
The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Dementia is a major global health issue in aging societies. Metabolic syndrome (MetS), a cluster of metabolic abnormalities, has been proposed as a modifiable risk factor for dementia, although existing evidence remains inconsistent. This review examined recent studies on the association between MetS and dementia risk in older adults.

Mechanisms of Cough Syncope as Evaluated by the Valsalva Maneuver
Kaohsiung Journal of Medical Sciences, 2007 Transcranial Doppler is often employed for the assessment of cerebral hemodynamics. The study by Chao et al in the February 2007 issue of the journal raises some important issues regarding the understanding of the mechanisms involved in cough syncope. We
