- Cerebral Microbleeds: Different Prevalence, Topography, and Risk Factors Depending on Dementia Diagnosis—The Karolinska Imaging Dementia Study
MR studies in more than 1500 patients with dementia revealed that 22% had microbleedsthat were predominantly lobar and occipital in cases of Alzheimer disease. Patients with microbleeds were older, male, and hypertensive. Prevalence, location, and risk factors of microbleeds varied depending on dementia diagnosis and may be taken into account when anticoagulating such patients.
- White Matter Correlates of Cognitive Impairment in Essential Tremor
A series of 55 patients with essential tremor and an equal number of age-matched controls were assessed clinically and by DTI. Alterations in executive and visual spatial functions correlated with DTI measures suggesting an anatomic basis for cognitive impairment in these patients.
- Impact of Time-to-Reperfusion on Outcome in Patients with Poor Collaterals
More than 200 patients with MCA +/- ICA occlusions who successfully reperfused with endovascular techniques were assessed. The probability of good outcome was not significantly influenced by onset-to-reperfusion and puncture-to-reperfusion periods in patients with good collaterals but dropped significantly in patients with poor collaterals.
