Alpha-synuclein in the frontal brain and thinking problems in Lewy body dementias
Cortical Alpha-Synuclein in Dementia
This project looks at whether buildup of the protein alpha-synuclein in the frontal part of the brain disrupts circuits that cause problems with planning, attention, and flexible thinking in people with Lewy body dementias.

What this research studies
From the patient's perspective, the research team is using lab models to add extra alpha-synuclein specifically to the prefrontal cortex and then watching individual brain cells with high-resolution two-photon imaging. They will track neuron activity and the tiny connections on neurons (dendritic spines) to see how these change when alpha-synuclein builds up. By focusing only on the frontal cortex, they aim to separate direct effects of the protein from changes caused by other brain systems. The goal is to learn how local protein aggregates could lead to the planning and attention problems seen in Lewy body dementias.
Who could benefit from this research
Good fit: This work is most relevant to people with Lewy body dementias — including Parkinson's disease dementia and dementia with Lewy bodies — especially those with troubles in planning, fluctuating attention, or flexible thinking.
Not a fit: People whose dementia is driven purely by Alzheimer-type pathology with no alpha-synuclein involvement, or those seeking immediate clinical treatments, are unlikely to get direct benefit from this preclinical work.
Why it matters
Potential benefit: If successful, this work could identify new circuit-level targets that lead to treatments to improve planning, attention, and flexible thinking in Lewy body dementia.
How similar studies have performed: Prior neuropathology and animal-model studies have linked alpha-synuclein to brain circuit problems, but directly imaging cortical neurons and spine plasticity in this focused way is relatively novel.
