Area of Science:

  • Neuroscience
  • Developmental Biology
  • Nutritional Science

Background:

  • Early brain development is highly sensitive to nutrient availability.
  • Vitamin deficiencies can disrupt crucial neurodevelopmental processes.
  • Understanding these effects is vital for preventing cognitive and functional impairments.

Purpose of the Study:

  • To review the impact of vitamin deficiencies on early brain development.
  • To discuss specific developmental problems and functional impairments caused by vitamin deficits.
  • To highlight critical periods and the role of vitamins in brain maturation.

Main Methods:

  • Review of existing literature on vitamin deficiency and brain development.
  • Analysis of experimental models and human studies.

  • Assessment of brain maturation using indices like reflex activity, cognition, and behavior.

    • Main Results:

    • Retinoid (vitamin A) deficiency/excess causes brain anomalies.
    • Vitamin D influences calcium-binding protein levels during development.
    • Vitamin E deficiency is linked to hemorrhage; thiamine deficiency to neuropathy (beriberi).
    • Pyridoxine (B6) deficiency impairs retinal development and perception.
    • Vitamin B12 deficiency affects infant behavior and motor tracts.
    • Folic acid deficiency delays electroencephalographic pattern maturation.
    • Interactions between vitamins (e.g., B6-B12, biotin-pantothenic acid) and nutrient absorption (iron-ascorbic acid) can exacerbate deficiencies.

    Conclusions:

    • Vitamin deficiencies pose significant risks to early brain development, affecting structure and function.
    • Specific vitamins play critical roles in neurogenesis, myelination, and cognitive maturation.
    • Addressing vitamin status during critical developmental periods is essential for optimal neurological outcomes.
