Abstract

Introduction: \ud The Meta VCI Map consortium performs meta-analyses on strategic lesion locations for vascular cognitive impairment using lesion-symptom mapping. Integration of data from different cohorts will increase sample sizes, to improve brain lesion coverage and support comprehensive lesion-symptom mapping studies.\ud \ud Methods: \ud Cohorts with available imaging on white matter hyperintensities or infarcts and cognitive testing were invited. We performed a pilot study to test the feasibility of multicenter data processing and analysis and determine the benefits to lesion coverage.\ud \ud Results: \ud Forty-seven groups have joined Meta VCI Map (stroke n = 7800 patients; memory clinic n = 4900; population-based n = 14,400). The pilot study (six ischemic stroke cohorts, n = 878) demonstrated feasibility of multicenter data integration (computed tomography/magnetic resonance imaging) and achieved marked improvement of lesion coverage.\ud \ud Discussion: \ud Meta VCI Map will provide new insights into the relevance of vascular lesion location for cognitive dysfunction. After the successful pilot study, further projects are being prepared. Other investigators are welcome to join.

Abstract

We provide a novel geometrical optical analysis of two coaxial photorefractive methods (isotropic and orthogonal). The size of the photorefractive pattern is defined in terms of the critical optical parameters without reference to specific camera parameters. A set of equations is derived that defines the following: a working range where the photorefractive pattern increases linearly with refractive error and pupil size, a dead zone where changes in refractive error do not influence pattern size, and critical values where vignetting by the camera lens becomes important. From this analysis optical parameters can be systematically adjusted to vary a photorefractor's working range. Small discrepancies found between measurements taken with model eyes indicated threshold and blooming effects that require calibration. Key words: Photorefraction, geometrical optics, refraction, infant vision, vision screening.

5. Correlations between MRI white matter lesion location and executive function and episodic memory

Author

Smith, E.E., Salat, D.H., Jeng, J., McCreary, C.R., Fischl, B., Schmahmann, J.D., Dickerson, B.C., Viswanathan, A., Albert, M.S., Blacker, D., and Greenberg, S.M.

Abstract

MRI white matter hyperintensity (WMH) volume is associated with cognitive impairment. We hypothesized that specific loci of WMH would correlate with cognition even after accounting for total WMH volume.
