Ultra-High Resolution PET in Aging, Neurodegeneration and Psychotic Disorders

The goal of this study is to use ultra-high-resolution (UHR) PET imaging to better understand how the brain and spinal cord change in healthy aging and in neurological and psychiatric disorders such as Alzheimer's disease (AD), Parkinson's disease and related movement disorders, amyotrophic lateral sclerosis (ALS), and psychotic disorders. Researchers will use the NeuroExplorer PET/CT system, a new scanner that can show very small structures in the brain and spinal cord in much more detail than regular PET. The main questions this study aims to answer are: * How do small but important brain regions (like the locus coeruleus, substantia nigra, and thalamic nuclei) change in healthy aging? * What early brain changes occur in neurodegenerative and psychotic disorders, and can they help improve early diagnosis? Participants will: * Undergo PET and MRI brain scans using different tracers that measure brain metabolism (18F-FDG), synaptic density (¹⁸F-SynVesT-1), dopamine transporters (¹⁸F-PE2I), and tau protein buildup (¹⁸F-MK6240). * Complete cognitive and clinical assessments related to memory, mood, and motor or psychiatric symptoms, depending on their group. This study will include healthy volunteers and patients with mild cognitive impairment due to Alzheimer´s disease, ALS, Parkinson's disease and related disorders, or psychotic disorders. The results will help create detailed brain imaging maps for healthy aging and identify early biomarkers for different diseases to support better diagnosis and treatment in the future.

Evaluation of a Structurally Suitable Neck Exoskeleton in Patients With Amyotrophic Lateral Sclerosis

The investigators will evaluate a new powered neck exoskeleton in patients with amyotrophic lateral sclerosis (ALS) to understand whether this device allows adequate head range of motion and achieves satisfaction from users. In this small cross-sectional device feasibility study, participants will be enrolled from the ALS clinic at the University of Utah Hospital. After obtaining written consent, participants will perform tasks using the neck exoskeleton. Tasks include computerized tracking tasks and simulated activities of daily living. Breaks will be added between tasks to avoid fatigue. Head-neck kinematics will be recorded, and range of motion will be computed. Participants will also report their satisfaction of the device.

Healey ALS MyMatch Common Screening Protocol

The goal of the Healey ALS MyMatch Common Screening Protocol (MCSP), an observational study, is to identify individuals with ALS who may be eligible to be matched to a currently enrolling ALS MyMatch trial. Participants will complete a MCSP Screening Visit and undergo clinical assessments, laboratory testing, and biomarker analyses to determine preliminary trial eligibility. The study also characterizes clinical, genetic, and biofluid biomarker profiles, assesses the prevalence of ALS-associated gene variants, and banks blood samples for future ALS and biomarker research. MCSP enables simultaneous screening for multiple trial-specific biomarkers and uses a targeted medical history form to optimize matching of participants to appropriate MyMatch trials.

Controlling Amyotrophic Lateral Sclerosis Motor Neuron Excitability Study

Following completion of the ALS Early Feasibility Study of the MyoRegulator® device for treatment of ALS (NCT06165172), the CALM study will further assess the feasibility of the MyoRegulator® device to treat ALS in an expanded number of individuals with ALS. CALM will gather additional preliminary evidence of clinical safety and potential effectiveness in this patient population with a longer follow-up period and additional secondary endpoints in a single-arm study prior to commencing a larger sham-controlled pivotal trial.

Tongue-strengthening Exercises in People With ALS.

This study is testing a tongue exercise program for people living with ALS to see if it can help support speech and swallowing. All participants will receive the treatment, and researchers will measure changes over time by comparing each person's results to their own earlier results. People who join the study will have two in-person visits, one virtual visit, and four weekly telehealth sessions with a speech-language pathologist. During these sessions, participants will practice tongue resistance exercises, complete speech and swallowing tasks, and answer surveys about their experience. They will also use a small device at home to measure tongue strength and swallowing. The exercise program involves pressing the tongue against a device several times a day, five days per week, for five weeks. Researchers want to learn if this program is safe, practical, and helpful for people with ALS.

Obi Medical Robot: Evaluating Effectiveness Related to Usability

This mixed-methods usability study evaluates the effectiveness of the Obi Gen 3 robotic feeding device in meeting user needs among providers, caregivers, and patients. Participants will complete a one-week trial using Obi in home, school, or community settings, followed by feedback surveys and optional interviews. The study seeks to validate that the device design meets usability requirements prior to broader deployment.
