Cognitive profile in patients with a first-ever lacunar infarct with and without silent lacunes: a comparative study
The objective of this study was to assess whether there were differences in the performance of a battery of neuropsychological tests in first-ever lacunar stroke patients with and without associated silent multiple lacunar infarctions found incidentally on the brain magnetic resonance imaging (MRI) scan. Methods: A total of 72 consecutive patients with first-ever lacunar infarction were studied 1 month after stroke. All patients underwent a comprehensive neuropsychological evaluation, which included the California Verbal Learning Test (CVLT), Phonetic Verbal Fluency Test (PMR), Semantic Verbal Fluency Test (category "anima...

Test could give two-year warning for Alzheimer's
Conclusion The researchers suggest that Alzheimer's disease can be predicted with an accuracy of 87.5% when thinning of the cortex in the right anterior cingulated gyrus is seen on MRI, alongside test results suggesting problems with recall and recognition. This research does not indicate a new "test", as MRI and psychological testing are standard procedures when investigating the signs and symptoms of dementia. What is novel in this approach is looking at a specific combination of results as a potential way of predicting which people with MCI may develop Alzheimer's disease. While this form of testing would be b...

Cognitive deficits of pure subcortical vascular dementia vs Alzheimer disease: PiB-PET-based study
Conclusions: Patients with PiB(–) SVaD were better at memory but worse at frontal function than patients with PiB(+) AD. The differences in memory/frontal functions observed between the 2 groups, however, could not differentiate all individual data due to some overlap in the cutoff threshold.
