Introduction: In Parkinson's disease (PD), rapid eye movement (REM) sleep behavior disorder (RBD) might either precede the appearance of motor symptoms, or develop during the disease course. PD patients with RBD are characterized by a higher burden of cognitive impairment and hallucinations. However, few studies have analyzed the clinical characteristics of PD patients according to the timeline of RBD onset.
Methods: PD patients have been retrospectively enrolled. Presence and onset of probable RBD (pRBD) has been evaluated using RBD Screening Questionnaire (score ≥ 6). Presence of Mild Cognitive Impairment (MCI) at baseline has been evaluated using the MDS criteria level II. Presence of motor complications and hallucinations has been evaluated at a 5-year follow-up.
Results: A total of 115 PD patients (65 men, 56.5%; mean age 62.5 ± 9.7 years; mean disease duration 3.7 ± 3.9 years) have been enrolled. Out of these, 63 fulfilled the diagnosis of pRBD (54.8%) with 21 (33.3%) reporting the RBD onset before the onset of the motor symptoms (PD-RBDpre), and 42 (66.7%) after the motor symptoms (PD-RBDpost). At enrolment presence of MCI was associated with PD-RBDpre patients (OR 5.04; 95% CI 1.33-19.05; p value 0.02). At follow-up, a higher risk of developing hallucinations was also associated with PD-RBDpre (OR 4.68; 95% CI 1.24-17.63; p = 0.022).
Conclusions: PD patients with RBD occurring before the onset of motor symptoms represent a subgroup of patients with a more severe cognitive phenotype and with a higher risk of developing hallucinations along the disease course, with significant implications in terms of prognostic stratification and therapeutic approach.

Continuous subcutaneous infusion of foslevodopa/foscarbidopa (LDP/CDP) may be effective in improving daytime symptoms in patients with Parkinson's disease (PD). We report on a PD patient for whom LDP/CDP treatment improved motor symptoms, sleep disturbances and sleep architecture as measured by the mobile two-channel electroencephalography/electrooculography recording system.

Introduction Parkinson's disease (PD) is primarily thought to be brought on by the death of dopaminergic neurons in the substantia nigra pars compacta of the basal ganglia. Communication difficulties are a common symptom of PD, affecting both motor speech and language systems. These challenges significantly impact the quality of life by reducing participation in communication, leading to social withdrawal, and increasing the risk of social isolation and stigma among individuals with PD.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative motor neuron disease that leads to a gradual loss of motor neurons manifesting as progressive weakness, dysarthria, and respiratory decline, with a relatively short life expectancy. Rheumatoid arthritis (RA) is an autoimmune disorder characterized by polyarthritis and affects multiple systems. Motor neuron involvement is rare in rheumatoid arthritis.

Purpose: Intrathecal morphine is increasingly used for pain management in laparoscopic colorectal surgery. While ropivacaine shows advantages of reduced cardiotoxicity and faster motor recovery compared to bupivacaine, the impact of intrathecal morphine-ropivacaine combination on postoperative recovery quality remains unclear. This study aimed to evaluate this combination's effect on recovery outcomes after laparoscopic colorectal surgery.

The estimated worldwide number of individuals diagnosed with Parkinson's disease (PD) might exceed 10 million by 2040. However, the underlying evidence for PD is unclear. Recent research in Parkinson's disease has focused on exploring the gut-brain axis.
