Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators aim to elucidate characteristics of structural and functional brain connectivity in patients with amyotrophic lateral sclerosis (ALS) and pseudobulbar affect (PBA) using diffusion kurtosis imaging (DKI) and magnetoencephalography (MEG).

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

Longitudinal imaging study. Baseline acquisition of DKI and resting state MEG of ALS and matched healthy controls. Participants with ALS will be monitored for a period of 6 months for symptoms of PBA. If developed, or not developed after 6 months, follow-up DKI and MEG will be acquired.

An additional sub-study will be performed in patients with ALS and newly developed PBA, where resting state MEG will be acquired after at least 7 days of symptomatic treatment independent of the study.
Primary Study Purpose

OTHER

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

Sex- and age matched, healthy control. Will only have baseline DKI and MEG performed.
