Objectives: The diagnostic entity of mild cognitive impairment (MCI) is heterogeneous, highlighting the need for data-driven classification approaches to identify patient subgroups. However, these approaches can be strongly determined by sample characteristics and selected measures. Here, we applied a cluster analysis to an MCI patient database from a neuropsychology clinic to determine whether the inclusion of patients with MCI with vascular pathology would result in a different classification of subgroups.

In the current healthcare climate, reimbursement for services is increasingly linked to the ability to demonstrate beneficial patient outcomes. Neuropsychology faces some unique challenges in outcomes research, namely, that neuropsychologists often do not follow patients over time and the effect of neuropsychological services on patient outcomes may not be fully realized until under another provider's care. Yet there is an urgent need for empirical evidence linking neuropsychological practice to positive patient outcomes. Read More

Individuals with substance use disorder (SUD) often present with cognitive impairments, which may impede their ability to make decisions for themselves, including treatment-related decisions. It is therefore important to assess whether individuals with SUD have adequate decision-making capacity. Indeed, there have not been any capacity assessment tools tailored for use with SUD populations that demonstrate adequate psychometric properties or that have the strong ethical foundation that is required of capacity assessment tools.
