Insights
Neurodevelopmental disorders show common polyunsaturated fatty acid (PUFA) depletion, suggesting abnormal fatty acid metabolism. This depletion may stem from genetic factors or oxidative stress, impacting cell signaling.
Area of Science:
- Neurobiology
- Biochemistry
- Genetics
Background:
- Neurodevelopmental disorders often co-occur.
- These disorders are linked to reduced polyunsaturated fatty acids (PUFAs) in plasma and red blood cells.
Purpose of the Study:
- To explore the implications of PUFA depletion in neurodevelopmental disorders.
- To investigate potential causes, including abnormal fatty acid metabolism, genetics, and oxidative stress.
Main Methods:
- Analysis of plasma and red cell membrane fatty acid composition.
- Review of existing evidence on co-morbidity and metabolic pathways.
Main Results:
- Evidence suggests a common feature of PUFA depletion across neurodevelopmental disorders.
- Abnormal fatty acid metabolism is indicated, potentially affecting cell signaling and eicosanoid synthesis.
Conclusions:
- PUFA depletion is a significant finding in neurodevelopmental disorders.
- Both genetic predisposition and oxidative stress are plausible contributors to decreased PUFAs.
Abstract:
There is evidence of co-morbidity in the neurodevelopmental disorders and they display depletion of polyunsaturated fatty acids (PUFAs) in their plasma and red cell membranes. This suggests an abnormal fatty acid metabolism, which may affect cell signalling and synthesis of eicosanoids. This common feature in the neurodevelopmental disorders may be genetic in origin: however, oxidative stress may also contribute to decreased PUFAs found in these disorders.
