Overview

Nicolas Niccolai, MD, PhD — Early Career PSP Researcher

Overview

Dr. Nicolas Niccolai is an early career physician-scientist at the University of California, San Francisco (UCSF) Department of Neurology, where he leads a research program focused on developing and validating advanced neuroimaging biomarkers for Progressive Supranuclear Palsy (PSP) and other atypical parkinsonian disorders. His work aims to improve early diagnostic accuracy, characterize disease progression, and establish imaging endpoints for clinical trials in tauopathies["@ucsf_neuro"].

Dr. Niccolai's research bridges the gap between advanced neuroimaging physics and clinical neurology, with a particular emphasis on translating novel MRI techniques into clinically useful biomarkers. His work has contributed significantly to understanding the structural and microstructural changes that occur in PSP, particularly in the brainstem and subcortical structures that define the disease's pathological signature.

Research Focus

Primary Research Areas

Dr. Niccolai's research program encompasses several interconnected areas that collectively aim to improve care for patients with PSP and related disorders:

1. Neuroimaging Biomarker Development

The central theme of Dr. Niccolai's work is developing MRI-based biomarkers that can:

• Detect Early Changes: Identify neuroimaging abnormalities before clinical symptoms become definitive
• Differentiate Diseases: Distinguish PSP from Parkinson's disease, corticobasal syndrome, and other parkinsonisms
• Track Progression: Characterize the temporal evolution of structural and microstructural brain changes
• Predict Outcomes: Forecast disease course and treatment response based on baseline imaging

2. Advanced MRI Techniques

Dr. Niccolai employs several advanced neuroimaging methodologies:

Diffusion Tensor Imaging (DTI):

• Water diffusion measurements that reveal white matter microstructure
• Metrics include fractional anisotropy (FA), mean diffusivity (MD), and axial/radial diffusivity
• Particularly useful for detecting early white matter involvement in PSP[@diffusion_2023]

• T1 relaxometry for myelin content estimation
• T2* mapping for iron deposition detection
• Magnetization transfer imaging for tissue integrity assessment

• Network connectivity analysis for understanding circuit dysfunction
• Default mode network and other network alterations in PSP

• Iron accumulation detection in deep gray matter structures
• Correlation with pathological burden

3. Brainstem and Subcortical Imaging

A distinctive aspect of Dr. Niccolai's work is his focus on brainstem structures, which are pathologically affected in PSP:

• Midbrain: Characterizing midbrain atrophy patterns specific to PSP
• Pons: Assessing pontine involvement in PSP variants
• Thalamus: Examining thalamic connectivity and structural changes
• Basal Ganglia: Detailed analysis of striatal and pallidal changes

Disease Focus

Progressive Supranuclear Palsy

PSP is the primary disease focus of Dr. Niccolai's research:

Clinical Variants Studied:

• Richardson's Syndrome (PSP-RS): Classic PSP presentation with vertical gaze palsy, postural instability, and akinesia
• PSP-Parkinsonism (PSP-P): A variant presenting with asymmetric onset and initial levodopa responsiveness
• Cortico-basal Syndrome (CBS): Overlapping syndrome with corticobasal degeneration
• Primary Progressive Aphasia (PPA): Language-predominant presentations

• What are the earliest imaging biomarkers that predict PSP development?
• How do different clinical variants of PSP map to distinct neuroimaging patterns?
• Can imaging biomarkers distinguish PSP from other 4R tauopathies?

Atypical Parkinsonisms

Beyond PSP, Dr. Niccolai's work extends to other atypical parkinsonian disorders:

• Multiple System Atrophy (MSA): Cerebellar and parkinsonian variants
• Corticobasal Syndrome (CBS): Asymmetric cortical and subcortical involvement
• Dementia with Lewy Bodies: Diffuse Lewy body disease with parkinsonian features

Dr. Niccolai's research benefits from extensive collaborations:

UCSF Internal Collaborations:
