Investigating epigenetic changes in Lewy body dementias using a new imaging technique

Imaging epigenetic dysregulation in the Lewy body dementias with [11C]Martinostat

['FUNDING_R01'] · MASSACHUSETTS GENERAL HOSPITAL · NIH-11076748

This study is looking at how certain changes in the brain's genetic material might affect memory and movement problems in people with Lewy body dementia and Parkinson's disease, using a special imaging tool to see these changes in real time.

What this research studies

This research focuses on understanding how epigenetic changes, which are modifications to the genome that do not alter the DNA sequence, may contribute to Lewy body dementias and Parkinson's disease. By using a novel imaging agent called [11C]Martinostat, researchers aim to visualize and assess the levels of histone deacetylases (HDACs) in the brains of living patients. This approach will help determine how these epigenetic changes relate to the progression of cognitive and motor impairments in these conditions. The study seeks to clarify whether the changes in HDAC expression differ between dementia with Lewy bodies and Parkinson's disease dementia.

Who could benefit from this research

Good fit: Ideal candidates for this research include individuals diagnosed with Lewy body dementia or Parkinson's disease.

Not a fit: Patients with other forms of dementia or neurological disorders unrelated to Lewy body pathology may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and potentially new treatments for Lewy body dementias and related disorders.

How similar studies have performed: While the use of imaging techniques to study epigenetic changes is relatively novel, there is growing interest and preliminary success in similar approaches in other neurological conditions.
