Dr. Boxer leads this initiative that involves eight sites across North America. 4RTNI evaluates participants with primary tauopathies, including PSP, CBS, and variant tauopathy syndromes. Additionally, 4RTNI enrolls healthy individuals. The study will provide information about the relative value of novel imaging techniques for diagnosis, as well as the value of imaging techniques versus testing of blood and cerebrospinal fluid (CSF) ‟biomarkers.”
Dr. Boxer leads the ALLFTD consortium together with Dr. Howard Rosen (UCSF) and Dr. Brad Boeve (Mayo Clinic). The ALLFTD consortium merges two previous research studies (ARTFL: Advancing Research and Treatment for Frontotemporal Lobar Degeneration and LEFFTDS: Longitudinal Evaluation of Familial Frontotemporal Dementia Subjects) and consists of 23 clinical sites that evaluate participants. ALLFTD studies both sporadic and genetic forms of frontotemporal lobar degeneration (FTLD), including behavioral variant FTD (bvFTD), primary progressive aphasia (PPA; both semantic and agrammatic variants), corticobasal syndrome (CBS/CBD), and progressive supranuclear palsy (PSP); genetic forms of FTLD may be due to mutations in several different genes, including C9orf72, MAPT, and GRN. Additionally, ALLFTD enrolls healthy participants who have a strong family history of FTLD syndromes, with or without a known genetic basis. More information is available at allftd.org.
Eye movements can be voluntary or involuntary. Changes in eye movements can reflect changes in the circuitry of the brain that controls the eyes. These can be due to problems with the neurons that move the muscles of the eye, or due to the brain circuitry that directs the eyes. Eye movements are generally studied in conjunction with another study (e.g. ALLFTD or similar) to provide context for the measurements.

Dr. Boxer is the Principal investigator for the Advancing Research and Treatment for Frontotemporal Lobar Degeneration (ARTFL) Research Consortium, an NIH-funded Rare Disease Network Clinical Research Network consisting of 18 sites that evaluate participants. ARTFL studies both sporadic and genetic forms of frontotemporal lobar degeneration (FTLD), including behavioral variant FTD (bvFTD), primary progressive aphasia (PPA; both semantic and agrammatic variants), corticobasal syndrome (CBS/CBD), and progressive supranuclear palsy (PSP). Additionally, ARTFL enrolls healthy participants who have a strong family history of FTLD syndromes, with or without a known genetic basis. More information is available on the Rare Disease Network website.
Approximately 30-40% of all frontotemporal dementia (FTD) cases are due to genetic causes. LEFFTDS  studies familial FTD caused by genetic variation in any of the three most common genes associated with frontotemporal dementia: microtubule associated protein tau (MAPT), granulin (GRN), and the chromosome 9 open reading frame 72 (C9orf72).  LEFFTDS co-enrolls eligible participants from ARTFL; both studies share a common infrastructure and assessments.
