Brief Summary

The goal of this observational study is to demonstrate the presence of neurotrophic factors in the breast milk of mothers with 18-month-old children and the persistence of these factors in breast milk after the age of 2 years. The main questions it aims to answer are:

  • Does the breast milk of mothers with 18-month-old babies contain Brain-Derived Neurotrophic Factor (BDNF), S100B protein and glial cell line-derived neurotrophic factor (GDNF)?
  • Does the breast milk continue to contain BDNF, s100B protein and GDNF and-after 24 months? Participants will be asked to give breastmilk at 3 separate times. Breast milk samples will be collected from mothers at 18th-month, 24th-month and ≥25 months of their babies. A total of 75 breast milk samples obtained from 25 mothers with their consent will be analyzed.

Outcome Measures

Primary Outcomes (9)

  • Analysis of BDNF in the breastmilk at 18 months

    Breast milk samples which were collected at the 18th month of the babies and stored in Eppendorf tubes at -20°C will be prepared for analysis by gradual thawing (breast milk will be taken to +4 C degree the day before analysis, room temperature on the day of analysis) in the 12th month of the study and will be analysed for BDNF with ELISA (E-lab-science; United States) method.

    Sample collection: 1-3 months of the study ; Analyze: 12th month of the study

  • Analysis of BDNF in the breastmilk at 24 months months

    Breast milk samples which were collected at the 24th month of the babies and stored in Eppendorf tubes at -20°C will be prepared for analysis by gradual thawing (breast milk will be taken to +4 C degree the day before analysis, room temperature on the day of analysis) in the 12th month of the study and will be analysed for BDNF with ELISA (E-lab-science; United States) method.

    Sample collection: 7-9 months of the study ; Analyze: 12th month of the study

  • Analysis of BDNF in the breastmilk at ≥25 months
