Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions).

The primary objective of this study is to determine whether treatment with pimavanserin or quetiapine is associated with a greater improvement in psychosis when used in a routine clinical setting to treat hallucinations and/or delusions due to Parkinson's disease (PD) or dementia with Lewy bodies (DLB) - collectively referred to as Lewy body disease (LBD).

Patients with Parkinson's Disease will be studied before, during, and after a deep brain stimulation implantation procedure to see if the stimulation location and the size of the electrical field produced by subthalamic nucleus (STN) DBS determine the degree to which DBS engages circuits that involve prefrontal cortex executive functions, and therefore have a direct impact on the patient's ability to inhibit actions.

The goal of this study is to learn whether patients who have a genetic mutation in the genes that cause alpha 1 antitrypsin deficiency also have genetic variation in nearby genes that can increase risk for reduced immune function and respiratory infections. To investigate this hypothesis, we will compare immune responses to the 20-valent pneumococcal conjugate vaccine (PCV20, Pfizer) between participants who have one abnormal copy of the SERPINA1 gene and either no COPD exacerbations, vs those with 2 or more COPD exacerbations in the past year.

The purpose of this study is to compare the effectiveness of inhaled bronchodilators delivered via nebulizers vs. dry powder inhalers (DPIs) in symptomatic participants with Chronic Obstructive Pulmonary Disease (COPD) who have airflow obstruction (FEV1/FVC ≤ 70%) and show significant air trapping (RV ≥ 120% of predicted).

The goal of this clinical trial is to determine if positive pressure during inspiration will improve penetration of aerosolized N-Acetylcysteine (NAC) into airway mucus plugs in the lungs of patients with asthma or Chronic Obstructive Pulmonary Disease (COPD). The main questions it aims to answer are: * Does delivery of aerosolized NAC with positive inspiratory pressure have a greater effect on mucus plug burden in the lungs than delivery of NAC without positive pressure.

The purpose of this study is to evaluate the site and mechanisms responsible for expiratory airflow limitation in chronic, treated, non-smoking, stable asthmatics with moderate to severe persistent expiratory airflow obstruction. Treatment will include inhaled corticosteroids and long acting beta2agonists.

Often when people with asthma get a virus caused by the common cold (rhinovirus), they also experience an increase or worsening of their asthma symptoms. The purpose of this study is to see if the study medication dupilumab helps prevent those with mild to moderate asthma from having increased asthma symptoms, after being exposed to an experimental rhinovirus inoculation.

The purpose of this study is to evaluate the effect of IPX203 (Crexont®) - the newest extended-release levodopa formulation - on the duration and quality of good on time, using a wearable device to monitor symptoms. 'Good on time' refers to a period (minutes to hours) when a patient experiences optimal symptom control due to effective medication and has better overall functioning without troublesome dyskinesias.

It is hypothesize that patients with clinically diagnosed neurodegenerative diseases will have significantly different receptor occupancy of 5HT2A receptors compared to a healthy age/sex-matched control group. This will be tested by measuring 5HT2A receptor density using the PET radioligand (R)-\[18F\]MH.MZ in both populations.

A prospective cohort of patients scheduled to undergo deep brain stimulation (DBS) implantation surgery for the treatment of Parkinson's disease as per standard of care will be invited to participate in this study. This mechanistic study is aimed at better understanding the role of basal ganglia beta band (11-35 Hz) oscillations and resonance in the manifestation of Parkinson's disease (PD) motor signs using closed-loop electrical neurostimulation, levodopa medication, and computational modeling.

Most individuals with asthma can effectively manage their symptoms and maintain normal lung function using inhaled medications, unfortunately, there is a subset of asthma sufferers whose symptoms, lung function, and risk of asthma attacks remain unimproved despite conventional inhaled medications. There could be several reasons for this.
