Verbal Reasoning Impairment in Parkinson's Disease.

Background: The aim of this study was to assess verbal reasoning (VR) functioning in patients with Parkinson's disease (PD) and healthy controls (HCs).

Methods: The non-demented PD patients and HCs matched by age and global cognition were enrolled in this study. VR was assessed with the verbal reasoning test (VRT), total score, and subsets.

Feasibility and usability of a non-immersive virtual reality tele-cognitive app in cognitive rehabilitation of patients affected by Parkinson's disease.

Background: Cognitive impairment is one of the most common non-motor features of Parkinson's disease (PD). The aim of the present study was to evaluate the feasibility and acceptability/usability of a protocol using a non-immersive virtual reality tele-cognitive app, performed remotely in a sample of Italian patients with PD.

Methods: Non-demented patients with mild PD were included in the study.

Impulsivity traits in eyelid myoclonia with absences.

Purpose: Eyelid myoclonia with absences (EMA) shares some clinical characteristics with juvenile myoclonic epilepsy (JME), in which impulsivity traits have been described. Aim of the study was to evaluate whether EMA patients could present a peculiar behavioural profile.

Methods: Patients with EMA, JME and healthy controls (HCs) were enrolled.

Phonemic Verbal Fluency and Midbrain Atrophy in Progressive Supranuclear Palsy.

Background: The neuropsychological profile of progressive supranuclear palsy (PSP) patients is mainly characterized by executive dysfunction, but the relationship between the latter and midbrain atrophy is still unclear.

Objective: The aims of the study were to investigate which test evaluating executive functioning is more frequently impaired in PSP patients and to evaluate the relationship between midbrain-based MRI morphometric measures and executive dysfunction.

Methods: PSP patients who had undergone a neuropsychological battery assessing executive functioning with the Frontal Assessment Battery (FAB), the phonemic verbal fluency F-A-S, the Raven's Progressive Colored Matrix, and the Stroop word colors test (time and errors) were enrolled in the study.

Changes in Motor, Cognitive, and Behavioral Symptoms in Parkinson's Disease and Mild Cognitive Impairment During the COVID-19 Lockdown.

The effects of the COVID-19 lockdown on subjects with prodromal phases of dementia are unknown. The aim of this study was to evaluate the motor, cognitive, and behavioral changes during the COVID-19 lockdown in Italy in patients with Parkinson's disease (PD) with and without mild cognitive impairment (PD-MCI and PD-NC) and in patients with MCI not associated with PD (MCInoPD). A total of 34 patients with PD-NC, 31 PD-MCI, and 31 MCInoPD and their caregivers were interviewed 10 weeks after the COVID-19 lockdown in Italy, and changes in cognitive, behavioral, and motor symptoms were examined.
