Iron deficiency is a widespread issue, particularly affecting women and young children. Early life iron deficiency can lead to cognitive impairments, even before anemia develops.

Area of Science:

  • Nutrition Science
  • Developmental Neuroscience
  • Public Health

Background:

  • Iron deficiency is highly prevalent in Latin American women and infants, posing a significant public health challenge.
  • Iron deficiency anemia is a preventable nutritional problem in children under five.
  • Cognitive alterations can occur due to iron deficiency during early development and potentially later in life.

Purpose of the Study:

  • To review the impact of iron deficiency on neural functioning, particularly during early development.
  • To highlight that organ changes occur before hemoglobin levels drop.
  • To discuss the metabolic pathways affected by iron deficiency that impact brain function.

Main Methods:

  • Literature review of studies on iron deficiency, brain iron, nutrition, and cognition.

  • Analysis of research on early life iron acquisition and its impact on the brain.
  • Synthesis of findings regarding the effects of iron deficiency on metabolic processes relevant to neural function.

    • Main Results:

    • Iron deficiency affects numerous metabolic processes crucial for brain function, including neurotransmitter synthesis and energy metabolism.
    • Morphological, physiological, and biochemical changes in organs can precede the development of anemia.
    • Early life iron deficiency has lasting consequences on cognitive development.

    Conclusions:

    • Iron deficiency is a critical factor influencing cognitive development and overall neural functioning.
    • Further research is needed to fully elucidate the role of brain iron in neural function.
    • Understanding iron acquisition by the brain is key to preventing long-term neurological consequences.
