Measuring dementia.

Abstract

Maudsley Tests of the Sensorium (used by clinicians to assess verbal memory and orientation) and Kendal's Memory for Design (used by psychologist to assess visual memory) were employed to differentiate between elderly patients with organic brain damage (neurologic disease, chiefly stroke) and those with functional psychiatric disorders which had been present in youth. There were 25 patients in each group. Both test differentiated organic from functional disorders. There was no statistically significant difference in the effectiveness of the two tests.

A penalized likelihood approach to magnetic resonance image reconstruction.

Currently, images acquired via magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI) technology are reconstructed using the discrete inverse Fourier transform. While computationally convenient, this approach is not able to filter out noise. This is a serious limitation because the amount of noise in MRI and fMRI can be substantial. In this paper, we propose an alternative approach to reconstruction, based on penalized likelihood methodology. In particular, we focus on non-linear shrinkage estimators and show that this approach achieves a great reduction in integrated mean squared error (IMSE) of the estimated image with respect to the currently used estimator. This approach is extremely fast and easy to implement computationally. In addition, it can be combined with various alternative approaches to MR image reconstruction and can be easily adapted to other, non-MRI contexts, in which the observed data and the quantities of interest are related via a linear transform.
