Besides the hallmark motor symptoms (rest tremor, hypokinesia, rigidity, and postural instability), patients with Parkinson's disease (PD) have non-motor symptoms, namely neuropsychiatric disorders. They are frequent and may influence the other symptoms of the disease. They have also a negative impact on the quality of life of patients and their caregivers. In this article, we will describe the clinical manifestations of the main PD-related behavioral disorders (depression, anxiety disorders, apathy, psychosis, and impulse control disorders). We will also provide an overview of the clinical and preclinical literature regarding the underlying mechanisms with a focus on the role of the dopaminergic and non-dopaminergic systems.

Background: The aim of this study was to examine the potential added value of including neuropsychiatric symptoms (NPS) in machine learning (ML) models, along with demographic features and Alzheimer's disease (AD) biomarkers, to predict decline or non-decline in global and domain-specific cognitive scores among community-dwelling older adults.
Objective: To evaluate the impact of adding NPS to AD biomarkers on ML model accuracy in predicting cognitive decline among older adults.
Methods: The study was conducted in the setting of the Mayo Clinic Study of Aging, including participants aged ≥ 50 years with information on demographics (i.

Background: Hemophagocytic lymphohistiocytosis (HLH), is characterized by systemic uncontrolled inflammation resulting from immune dysregulation secondary to various triggers, including genetics, infections, autoimmune diseases, and malignancies. Macrophage activation syndrome (MAS) is an immune dysregulation phenomenon, in which an underlying rheumatological disease is present. We report a rare, interesting case of a middle-aged female, with a systemic lupus erythematosus (SLE) flare complicated by macrophage activation syndrome (MAS), in which tuberculous meningitis (TBM) was the identified trigger.

Objective: Catatonia is a neuropsychiatric disorder that is associated with a range of medical and psychiatric illnesses. Although many single-center studies have been conducted, uncertainty over the population-based incidence and prevalence of the disorder remains. This study reports on the incidence and prevalence rates of catatonia extrapolated from two large epidemiologic studies in the United Kingdom and United States.

Objectives: Niemann-Pick type C (NPC) is a rare, autosomal recessive, neurodegenerative disorder caused by biallelic pathogenic variants in the or genes, leading to lysosomal lipid accumulation. NPC has an incidence of 1 in 100,000 live births and presents with a wide range of symptoms affecting visceral organs and the central nervous system. We aim to describe the diverse clinical presentations of NPC through case studies.

Background: Chronic rhinosinusitis (CRS) is a global health issue, with some patients experiencing anxiety and depression-like symptoms. This study investigates the role of HMGB1 in anxiety and depression-like behaviors associated with the microglial Notch1/Hes-1 pathway in CRS mice.
Methods: A CRS mouse model was developed, and behavioral assessments were conducted to evaluate anxiety and depression-like behaviors.
