Digital Health Technologies for Progressive Supranuclear Palsy and Dementia With Lewy Bodies

Progressive supranuclear palsy (PSP), mild cognitive impairment with Lewy bodies (MCI-LB), and Dementia with Lewy Bodies (DLB) are severe neurodegenerative diseases that cause significant motor impairment impacting daily function. Researchers at BioSensics, Johns Hopkins School of Medicine, Massachusetts General Hospital and their collaborators aim to conduct an analytical and clinical validation of wearable-based digital health technologies for monitoring upper and lower limb function in PSP, MCI-LB and DLB that could enable frequent, at-home monitoring and be incorporated into future clinical trials.

Biofluid Research on Age-Related or Inherited Neurodegeneration

The aim of this study is to contribute to and continue to sustain a repository of blood samples, nucleic acid (DNA and/or RNA) samples, family history information, and other demographic information from individuals with age-related neurodegenerative conditions, or their family members who may or may not be at risk for similar conditions. This study will continue to further expand research into the molecular and genetic basis of these diseases and their risk factors.

Treatment of Disturbed Sleep in Progressive Supranuclear Palsy (PSP)

Prior research has identified profound sleep disruption in individuals with PSP. Not only were these individuals sleeping relatively short periods at night, they were also not recuperating lost sleep during the day. Research also showed the relative preservation of a series of nuclei key in regulating wake and arousal. Investigators believe that therapeutically targeting wake promoting centers with a specific medication will improve sleep quality and overall well-being in PSP. To study this, investigators will be doing a double blind, within subject, remote clinical trial with 3 conditions: suvorexant- which targets a wake promoting system, zolpidem- a standard hypnotic that engages sleep promoting systems, versus placebo. Each condition will last 1 week and will be separated by a 1 week washout period on no sleep medications. Investigators will measure sleep patterns and daytime symptoms to determine if suvorexant, zolpidem, or both medications are safe and effective for treating sleep disturbances and improving overall well-being in PSP.

Tracking and Predicting How Brain Damage Spreads in Neurodegenerative Diseases

Neurodegenerative diseases, including frontotemporal lobar degeneration (FTLD) spectrum syndromes, are characterized by the accumulation of insoluble protein aggregates in the central nervous system. A common feature of these diseases is that pathological changes accumulate over time following a stereotyped spatial pattern, which contributes to the onset and progression of clinical symptoms. Until recently, the causes of such progression were still unknown. Recent pathological and neuroimaging studies have, however, suggested that insoluble and pathological protein aggregates are able to alter the conformation of neighboring proteins and spread through cell-to-cell transmission. According to this theory, called the 'brain connectome,' the brain network is established as a set of nodes, which correspond to different anatomical regions. These brain networks are highly connected to each other and their internal organization is fundamental for an efficient integration of information coming from different regions and to guarantee adequate levels of motor/cognitive performance. Thanks to magnetic resonance studies and research in the field of brain networks, it is possible to understand the pathophysiology of neurodegenerative diseases and reveal the connectivity profiles associated with different clinical outcomes. The main objective of this project is to explore the mechanisms of neurodegeneration associated with the different FTLD spectrum syndromes, and in particular the hypothesis that the neurodegenerative process is driven by the structural architecture of the brain 'connectome'. The ultimate goal is to apply mathematical models to structural and functional connectivity data to predict the evolution of the neurodegenerative process in sporadic and genetic forms of Frontotemporal Lobar Degeneration Disease. This study aims to investigate the spatiotemporal progression of neurodegeneration in frontotemporal lobar degeneration (FTLD) using advanced neuroimaging and connectomics. 360 patients with sporadic FTLD (including bvFTD, semantic and nonfluent PPA, PSPs, CBS, and ALS) and 65 patients with genetic FTLD (MAPT, GRN, and C9orf72 mutati will be enrolled. The study also plans to enroll 120 subjects who are members of families carrying FLTD-associated mutations (including 60 mutation carriers). Finally, 100 healthy controls will also be enrolled, including 50 young healthy controls and 50 healthy controls comparable with patients by sex and age. Participants will undergo clinical, neuropsychological, and behavioral assessments, blood and Cerebrospinal fluid (CSF) collection, and multimodal 3Tesla Magnetic Resonance Imaging MRI at baseline and every 6 months for up to 2 years. Primary objectives include mapping longitudinal changes in structural and functional brain networks, developing predictive models of network degeneration and clinical decline, and characterizing protein-specific patterns of network degeneration. Secondary aims include identifying early network biomarkers in presymptomatic carriers and correlating network changes with biological markers.

The CurePSP Genetics Program

This study is an observational, prospective genetic study. It aims to obtain DNA for research and testing from patients with PSP, CBS, MSA, and related neurological conditions and their families. Up to 1,000 adults who have been clinically diagnosed with PSP, CBS, MSA, or related neurological conditions will be enrolled. The study intervention involves sequencing of participant blood samples using non-CLIA-approved whole genome sequencing at the National Institutes of Health. Pathogenic variants that are deemed possibly related to these conditions will be confirmed using CLIA-approved testing. The study involves minimal risk to participants.

To differentiate FTLD-TDP and FTLD-tau during life using biomarkers for neuroinflammation; 3. To identify biomarkers to predict and monitor disease progression in FTLD; Secondary aim: 1\. To explore the role of brain clearance in the disease process of FTLD. Participants will undergo 7T MRI scans, blood and CSF collection, clinical, neurological, and neuropsychological evaluation.

Collection of Digital Parameters From Parts of the Neurological Examination Using an Eye Tracker

The neurological examination (NE) is a cornerstone of clinical neurology, with ocular motor assessment being a key component. Technology offers an opportunity to augment and standardize parts of the NE. Eye-tracking systems provide objective quantitative data on eye movements by continuously tracking the eye over time. This data can be used to derive parameters like saccadic latency, gaze velocity, and fixation stability with a precision that is impossible to achieve through human observation by neurologists. The integration of such technology could enhance the traditional NE. Before such technology can be widely adopted, its feasibility and acceptability in a clinical population must be established. The primary purpose of this study is to assess the usability of a novel eye-tracking system from the patient's perspective when used in a clinical settings. A secondary purpose is to determine if quantitative data from the eye-tracker correlate with the findings of the traditional clinical neurological examination and to explore whether eye-tracking can provide additional, complementary information not typically captured by standard clinical assessment. To achieve these aims, the study will assess several outcome measures. The primary outcome measure is the Usability of the Eye-Tracking System, which will be measured using the System Usability Scale (SUS). Beyond the primary objectives, this study will investigate two secondary objectives. The first involves assessing the relationship between quantitative eye-tracking parameters and clinical ocular motor assessment. Specifically, the investigators will analyze objective, numerical data obtained from eye-tracking systems and the clinician's subjectively graded assessment of ocular movements derived from the standard neurological examination. The second is the exploratory analysis of novel eye-tracking biomarkers. This involves quantifying and analyzing eye-tracking parameters not typically assessed during a routine NE. For example, the dynamics of the pupillary light reflex or the frequency of microsaccades. The aim is to identify potential digital biomarkers that could provide additional objective insights into ocular motor function and neurological status.
