Investigating Complex Neurodegenerative Disorders Related to Amyotrophic Lateral Sclerosis and Frontotemporal Dementia

Objectives The primary objective is to evaluate patients referred with a diagnosis of frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS), or related adult-onset neurodegenerative disorders to assess patient eligibility for ongoing protocols. The secondary objective is to develop and maintain a registry of characterized patients and presymptopmatic carriers of gene mutations that cause ALS-FTD spectrum disorders. The exploratory objectives are to obtain biospecimens from clinically characterized patients to carry out laboratory-based studies aimed at understanding the molecular pathways and genetic overlap between these neurodegenerative disorders and to perform 7 tesla magnetic resonance imaging studies to identify imaging biomarkers of neurodegeneration. Study population Adults referred with clinical diagnoses of frontotemporal dementia, motor neuron disorder, or related adult-onset neurodegenerative disorder. Presymptomatic carriers of genes known to cause familial FTD or ALS Design All participants will undergo clinical tests to confirm diagnoses and to stage disease severity, including a standard battery of tests to measure cognitive and motor functions. Participants may opt-in for research procedures such as phlebotomy, skin biopsy, leukapheresis, and lumbar puncture to obtain biospecimens for laboratory research, and magnetic resonance imaging or transcranial magnetic stimulation may be used to explore biomarkers of disease. Outcome measures Clinical information will be analyzed as part of our research to identify common features and differences among participants.
