    Can participants use Riluzole?

    Inclusion Criteria:
    -Clinically diagnosed with amyotrophic lateral sclerosis (ALS), fronto-temporal dementia (FTD), or both; or a carrier of a mutation known to cause ALS or FTD (with or without symptoms); or a normal control.
    -Participant is able and willing to undergo testing (psychometric testing, MRI or CT, PET, radioactive tracer injection; for those unable to undergo an MRI, CT will be used to generate regions-of-interest).
    -Pre-menopausal women will undergo a urine pregnancy test within 24 hours of drug administration.

    Exclusion Criteria:
    -Has any condition that, in the Investigator's opinion, could increase risk to the participant, limit the participant's ability to tolerate the experimental procedures, or interfere with the collection/analysis of the data (for example, participants with significant respiratory involvement may not be able to lie flat during the scanning procedures).
    -Is deemed likely unable to perform the imaging procedures for any reason.
    -Has a high risk for Torsades de Pointes or is taking medications known to prolong QT interval.
    -Has hypersensitivity to F 18 T807 or any of its excipients.
    -Contraindications to PET, PET-CT or MR (e.g. electronic medical devices, inability to lie still for long periods) that make it unsafe for the individual to participate.
    -Severe claustrophobia.
    -Currently pregnant or breast-feeding.
