Exploring brain connectivity in ALS and emotional symptoms

Structural and Functional Networks in ALS: An Insight Into Pseudobulbar Affect

Not applicable Interventional Aalborg University Hospital · NCT06396260

This study is testing how brain connections in people with ALS relate to emotional symptoms like sudden laughter or crying to better understand what's happening in their brains.

What this trial studies

This study investigates the structural and functional brain connectivity in patients diagnosed with amyotrophic lateral sclerosis (ALS) who also experience pseudobulbar affect (PBA). Utilizing advanced imaging techniques such as diffusion kurtosis imaging (DKI) and resting state magnetoencephalography (MEG), the researchers aim to gain insights into the neural networks involved in these conditions. By understanding these connectivity patterns, the study hopes to shed light on the underlying mechanisms of PBA in ALS patients.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with ALS within the last six months who do not have significant comorbid conditions.

Not a fit: Patients with severe psychiatric disorders, other neurodegenerative diseases, or contraindications for MRI and MEG scans may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and management of emotional symptoms in ALS patients.

How similar studies have performed: While studies on brain connectivity in ALS exist, this specific approach using DKI and MEG for PBA is relatively novel.
