Background: Although cognitive deficits are frequent in multiple sclerosis (MS), screening for them with tools such as the Montreal Cognitive Assessment (MoCA) test is usually not performed unless there is a subjective complaint. The Multiple Sclerosis Neuropsychological Questionnaire (MSNQ) is among the instruments most commonly used to assess self-reported subjective complaints in MS. Nonetheless, it does not always accurately reflect cognitive status; many patients with cognitive deficits thus fail to receive appropriate referral for detailed neuropsychological evaluation.

: Neuropsychological evaluations in a geriatric population have an assortment of challenges due to increased risk in the population for chronic/acute medical conditions, varied psychiatric disorders, and chronic negative lifestyle behaviors, all which impact one's cognitive functioning. One relatively new challenge is conducting cognitive evaluations within an elderly transgender population. There is a considerable lack of specific normative data in neuropsychological evaluations for transgender individuals due to the prevalence of binary gender categorization in current scoring protocols.

Cognitive impairment is the most common neurological manifestation in NF1 and occurs in 30-70% of NF1 cases. The onset and severity of each specific cognitive deficit varies greatly from child to child, with no apparent external causes. The wide variability of phenotype is the most complex aspect in terms of management and care. Read More

Purpose: To know whether mild cognitive impairment (MCI) patients will develop Alzheimer's disease (AD) dementia in very short time or remain stable is of crucial importance, also considering new experimental drugs usually tested within very short time frames. Here we combined cerebrospinal fluid (CSF) AD biomarkers and a neurodegeneration marker such as brain FDG-PET to define an objective algorithm, suitable not only to reliably detect MCI converters to AD dementia but also to predict timing of conversion.

Methods: We included 77 consecutive MCI patients with neurological/neuropsychological assessment, brain 18F-FDG-PET and CSF analysis available at diagnosis and a neuropsychological/neurological evaluation every 6 months for a medium- to a long-term follow-up (at least 2 and up to 8 years).

Department of Human and Social Science, Università degli Studi di Bergamo, Bergamo, Italy.

Maintaining social skills such as Theory of Mind (ToM) competences is important to counteract the conversion into dementia in Mild Cognitive Impairment (MCI). Multidimensional nonpharmacological interventions demonstrated their potential in improving cognitive and behavioral abilities; however, little is known about the long-term effect of such interventions on social skills in people with MCI. The aim of this longitudinal study was to monitor ToM competences considering both cognitive and affective domains in an amnestic MCI (aMCI) sample involved in a home-based multistimulation treatment (MST@H).

: Embedded performance validity tests (PVTs) allow for continuous and economical validity assessment during neuropsychological evaluations; however, similar to their freestanding counterparts, a limitation of well-validated embedded PVTs is that the majority are memory-based. This study cross-validated several previously identified non-memory-based PVTs derived from language, processing speed, and executive functioning tests within a single mixed clinical neuropsychiatric sample with and without cognitive impairment.: This cross-sectional study included data from 124 clinical patients who underwent outpatient neuropsychological evaluation.

In 2005, the 3q29 Deletion Syndrome was identified and defined as a rare chromosomal anomaly that effects approximately one in 30,000-40,000 children. It has a complex neuropsychiatric profile but often results in developmental delay, intellectual disability, attentional deficits, classic physical traits, behavioral health disturbances, as well as social and emotional issues. Rarely has this syndrome been seen and evaluated in fraternal twins, only one of whom has the 3q29 Deletion Syndrome. Read More

Due to the lack of pharmacological treatment for dementia, timely detection of subjects at risk can be of seminal importance for preemptive rehabilitation interventions. The aim of the study was to determine the usability of the smart aging serious game (SASG), a virtual reality platform, in assessing the cognitive profile of an amnestic mild cognitive impairment (aMCI) population, its validity in discriminating aMCI from healthy controls (HC), and in detecting hippocampal degeneration, a biomarker of clinical progression towards dementia. Thirty-six aMCI and 107 HC subjects were recruited and administered the SASG together with a neuropsychological evaluation. Read More

The Slick, Sherman, and Iversion (1999) criteria for malingered neurocognitive dysfunction (MND) for malingered neurocognitive dysfunction (MND) are considered a major milestone in the field's operationalization of neurocognitive malingering and have strongly influenced the development of malingering detection methods, including serving as the criterion of malingering in the validation of several performance validity tests (PVTs) and symptom validity tests (SVTs) (Slick, D.J.

There is currently a need for engaging, user-friendly, and repeatable tasks for assessment of cognitive and motor function in aging and neurodegenerative diseases. This study evaluated the feasibility of a maze-like Numberlink puzzle game in assessing differences in game-based measures of cognition and motor function due to age and neurodegenerative diseases. Fifty-five participants, including young (18-31 years, = 18), older (64-79 years, = 14), and oldest adults (86-98 years, = 14), and patients with Parkinson's (59-76 years, = 4) and Huntington's disease (HD; 35-66 years, = 5) played different difficulty levels of the Numberlink puzzle game and completed usability questionnaires and tests for psychomotor, attentional, visuospatial, and constructional and executive function.

Background: The first years of relapsing-remitting multiple sclerosis (RRMS) constitute the most vulnerable phase for the progression of cognitive impairment (CImp), due to a gradual decrease of compensatory mechanisms. In the first 10 years of RRMS, the temporal volumetric changes of deep gray matter structures must be clarified, since they could constitute reliable cognitive biomarkers for diagnostic, prognostic, and therapeutic purposes.

Methods: Forty-five cognitively asymptomatic patients with RRMS lasting ≤ 10 years, and with a brain MRI performed in a year from the neuropsychological evaluation (Te-MRI), were included. Read More

Fundación San Andrés, Mendoza., Argentina.

Introduction: Refractory epilepsy means that the seizures are untreatable, and therefore one of the interventions that makes it possible to eliminate them or to accomplish a reduction in the number of seizures is neurosurgery.

Development: A neuropsychological evaluation model aimed at measuring the cognitive performance of adult patients who are candidates for epilepsy surgery is proposed. In line with the proposals most frequently put forward by the various reference centres for epilepsy, an open protocol is proposed that is aimed at obtaining a baseline of overall cognitive performance, cognitive reserve and manual dominance, as well as cognitive processes such as attention, language, visuoconstructive and manipulative skills, memory and executive functions, among others, without neglecting the psychopathological examination and the patient's quality of life.

The clinical and neuropsychological features were non-specific and overlapping with those of other rapidly progressing neurodegenerative disorders. However, brain MRI played a pivotal role in the diagnosis, showing cortical diffusion restriction, particularly in the parietal lobes and posterior cingulum, with sparing of the perirolandic cortex, typical of Creutzfeldt-Jakob disease (CJD).
