The effect of sleep disturbances on the incidence of dementia for varying lag times.

Background: Few studies have addressed the association of sleep disturbances with incident dementia with long lag times. We add to this literature by investigating how lag times varying from 2.2 to 23.

Hemoglobin Decrements are Associated with Ischemic Brain Lesions and Poor Outcomes in Patients with Intracerebral Hemorrhage.

Background: Acute ischemic lesions seen on brain magnetic resonance imaging (MRI) are associated with poor intracerebral hemorrhage (ICH) outcomes, but drivers for these lesions are unknown. Rapid hemoglobin decrements occur in the initial days after ICH and may impair brain oxygen delivery. We investigated whether acute hemoglobin decrements after ICH are associated with MRI ischemic lesions and poor long-term ICH outcomes.

Machine Learning Models for 3-Month Outcome Prediction Using Radiomics of Intracerebral Hemorrhage and Perihematomal Edema from Admission Head Computed Tomography (CT).

: Intracerebral hemorrhages (ICH) and perihematomal edema (PHE) are respective imaging markers of primary and secondary brain injury in hemorrhagic stroke. In this study, we explored the potential added value of PHE radiomic features for prognostication in ICH patients. : Using a multicentric trial cohort of acute supratentorial ICH ( = 852) patients, we extracted radiomic features from ICH and PHE lesions on admission non-contrast head CTs.

Hypertension and orthostatic hypotension in the elderly: a challenging balance.

Hypertension and orthostatic hypotension (OH) frequently coexist in the older population, both stemming from impaired blood pressure (BP) regulation. Managing hypertension in patients with OH presents a significant clinical challenge, particularly in frail older adults who are also prone to falls. Hypertension treatment is often suboptimal in this population due to concerns over the potential increased risk of falls associated with treatment.
