Research description

As a Senior Researcher, I lead research projects on MRI-PET imaging to understand the dynamics of protein aggregation, neuroinflammation and brain structural changes in neurodegenerative diseases, from early preclinical stages of Alzheimer's disease (AD) and fronto-temporal degeneration (FTD). In collaboration with clinicians, the ultimate aim of my research line is to develop early diagnostic and prognostic biomarkers with high clinical utility. 

Current research projects: 

1) "Investigate a novel measure of cortical microstructure and its relationship to protein aggregation in preclinical Alzheimer's disease and the spectrum of FTD-ALS"

In this project, I apply a novel diffusion-weighted imaging (DWI) technique to measure cortical microstructure as a promising early diagnostic and prognostic biomarker in preclinical AD and across diverse neurodegenerative diseases. In this line of research, I have a close international collaboration with Patrizia Vannini from Massachusetts General Hospital / Harvard Medical School, Boston, US, and Juan Fortea and Victor Montal of Universitat Autònoma de Barcelona.

Besides preclinical AD, I have investigated cortical microstructure in relation to astrocytosis in familial forms of AD:

2) "Toward early prognostic biomarkers in the ALS-FTD spectrum"

Together with Caroline Ingre and Sebastian Lewandowski at KI, we aim to integrate FDG-PET imaging and fluid (CSF and plasma) biomarkers of metabolic, vascular and neuroinflammatory changes in patients on the ALS-FTD spectrum. The aim of this project is to develop objective biomarker tools that may help clinicians to improve prognosis of speed of disease progression in patients, which will help determine their optimum patient management and treatment options.

4) "Untangling heterogeneous pathways to Alzheimer's disease by investigating discordance between amyloid CSF and PET imaging biomarkers"

A. Sala, A. Nordberg, E. Rodriguez-Vieitez. "Longitudinal Longitudinal pathways of cerebrospinal fluid and positron emission tomography biomarkers of amyloid-β positivity", Molecular Psychiatry 2020, Dec 11; JIF 12.38


In this study we identifed two alternative pathological pathways leading to Alzheimer's disease. Using a large longitudinal dataset of amyloid protein accumulation as measured by brain images and biochemical samples from the cerebrospinal fluid, we showed that Alzheimer’s-related amyloid pathology can be detected first in the brain in some individuals, or first in the cerebrospinal fluid in other individuals, adding to evidence that Alzheimer's is a heterogeneous disease. These results have biological and clinical implications. 

This research is as part of the EU-funded AMYPAD project, "Amyloid imaging to prevent Alzheimer's disease", https://amypad.eu (KI principal investigator: Agneta Nordberg)



Besides image processing and quantification, I have a strong focus on novel statistical approaches to unravel the associations between brain morphology, underlying molecular biology changes in the central nervous system and the periphery, and cognition.

Overall, I have co-authored over 55 peer-reviewed publications in international journals. I have co-supervised two PhD students and mentored several master and undergraduate students, collaborate with clinicians, and currently co-supervise PhD student Mona-Lisa Malarte, KI.

Through my ongoing projects, I plan to strengthen my collaboration with other national and international research institutions and hospitals, and to focus on research with high potential for patient benefit.
