LCPUFA Supplementation: A Multi-Modality Imaging Study

October 6, 2015 updated by: Kathleen Gustafson, Ph.D.
The purpose of this study is to take images of the brain in order to see if long-chain polyunsaturated fatty acid (LCPUFA) exposure during infancy influences brain structure and function in middle childhood.

Study Overview

Detailed Description

LCPUFAs are essential fatty acids that are found in all cells of the body, particularly in the brain, retina and other nervous tissue. LCPUFAs are found naturally in seeds, nuts, fish and human breast milk. The body can also make LCPUFAs from shorter-chain fatty acid precursors.

The researchers in the study have previously found that LCPUFA supplementation during infancy has a beneficial effect on vision and development in the early years of life. However, researchers feel there is a growing need to better understand if there are structural and/or functional changes in the brain that explain these benefits. It is also important to understand if changes in development are still present later in childhood.

Cohorts and Interventions

Group / Cohort
Previous LCPUFA Supplementation
Children between the ages of 7 and 10 that were previously enrolled in a study of supplemented LCPUFA formula.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Event-Related Field (ERF) Amplitude and Latency
Time Frame: Within 1 year post enrollment
We will use an MEG Event-Related Field (ERF) to study the development of children's cognitive capabilities. The waveform components associated with information processing and response inhibition will be measured in order to assess the developmental progress of LCPUFA effects with increasing age.
Within 1 year post enrollment
Regional gray and white matter brain volume
Time Frame: Within 1 year post enrollment
Structural brain imaging is widely used to measure gray and white matter maturation patterns in young children. We will use automated, sensitive, and validated methods to test whether LCPUFA supplementation positively impacts changes in the brain associated with higher functioning and intelligence.
Within 1 year post enrollment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Identify structural and metabolic mediators
Time Frame: Within 1 year post enrollment
In a single imaging session, we will measure metabolic biomarkers associated with cellular mechanisms such as bioenergetics, membrane status, and oxidative state, each of which have been implicated as associated with LCPUFA supplementation.
Within 1 year post enrollment
