Exploring moments of clarity in severe dementia patients

Paradoxical Lucidity in Severe End-Stage Dementia

Observational NYU Langone Health · NCT05234866

This study is trying to understand rare moments of clarity in people with severe dementia to see if there are patterns or signs in their brain activity that can help explain these episodes.

What this trial studies

This observational study investigates episodes of paradoxical lucidity in patients with severe end-stage dementia. It aims to develop a definition and measurement scale for these episodes while identifying potential electro cortical biomarkers associated with them. The study will be conducted in two phases, starting with data collection through online surveys and focus groups, followed by assessments using symptom diaries and real-time video EEG monitoring. The goal is to better understand the mechanisms behind these transient moments of clarity.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with advanced dementia, specifically those diagnosed with a GDS score of 7 and accepted for hospice care.

Not a fit: Patients with cognitive impairment due to conditions other than dementia or those with less severe dementia (GDS score <7) may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into cognitive functions in severe dementia, potentially improving care strategies.

How similar studies have performed: While episodes of paradoxical lucidity have been reported anecdotally, this study represents a novel approach to systematically investigate this phenomenon.
