Impaired option generation underpins deficient reasoning in Parkinson's disease patients with apathy.

Apathy is a debilitating neurological syndrome known to be associated with executive dysfunction, particularly affecting abstract reasoning. However, the underlying cognitive mechanism remains unclear. Recently, it has been proposed that one cognitive process disrupted in apathy is option generation.

The relationship between early post-stroke cognition and longer term activities and participation: A systematic review.

This systematic review examined whether early cognitive impairment after stroke is predictive of outcome within the "activity" and "participation" domains of the International Classification of Functioning, Disability and Health (ICF) at 6-12 months post-injury. Studies were included if cognitive functioning was assessed within 6 weeks of injury and outcome was measured at least 6 months post-injury. PsycINFO, MEDLINE, CINAHL and EMBASE databases were searched and 14 studies were identified.

Role of clinical neuropsychology in deep brain stimulation: Review of the literature and considerations for clinicians.

Deep Brain Stimulation (DBS) is an effective surgical therapy for several neurological movement disorders. The clinical neuropsychologist has a well-established role in the neuropsychological evaluation and selection of surgical candidates. In this article, we argue that the clinical neuropsychologist's role is much broader, when considered in relation to applied psychologists' core competencies.

Rehabilitation of face-processing skills in an adolescent with prosopagnosia: Evaluation of an online perceptual training programme.

In this paper we describe the case of EM, a female adolescent who acquired prosopagnosia following encephalitis at the age of eight. Initial neuropsychological and eye-movement investigations indicated that EM had profound difficulties in face perception as well as face recognition. EM underwent 14 weeks of perceptual training in an online programme that attempted to improve her ability to make fine-grained discriminations between faces.
