Prism adaptation training (PAT) as a treatment for visuospatial neglect (VSN) involves two components: recalibration and realignment. We conducted a randomized controlled trial with PAT protocols requiring different degrees of recalibration and realignment, by using a single or multi-step protocol and varying visibility of the pointing movement. Twenty-five VSN patients received an alertness treatment without prisms, followed by four PAT protocols, encompassing a multi- or single-step procedure with terminal exposure, a single-step procedure with concurrent exposure, and sham PAT, presented in random order.

Prism adaptation (PA) is one treatment option and may involve two components: recalibration (more strategic) and realignment (more implicit). We examined whether recalibration or realignment is the driving force in neglect rehabilitation using PA.

As a first step, assessment of CI is often accomplished by using screening instruments (level I diagnosis). Three commonly used instruments are the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Parkinson Neuropsychometric Dementia Assessment (PANDA).

This meta-analysis examined the discriminant validity of the WCST for the assessment of mental shifting, considered as an essential subcomponent of executive functioning, against traditional psychometric intelligence tests. A systematic search was conducted, resulting in 72 neuropsychological samples for the meta-analysis of relationships between WCST scores and a variety of intelligence quotient (IQ) domains.

Along with the characteristic motor symptoms of the disorder, especially bradykinesia, cognitive deficits can often be found prior to the onset of the disorder. These mainly concern executive functioning.
