Determination of weight of human brain for population of Ethiopia- an Autopsy Study

Abstract

Background: Medical documentations and teaching dictums as to age related changes in weight of the Brain, and weight of the Brain in respect to gender and Race are the issues need to be addressed again & again. Though the available literature do mention normal weight of the Brain to that given population under study but populations of third word like Ethiopia lack sufficient data as to the normal weight of the brain. Objective: This study was done at St Paul Hospital & Millennium Medical College Addis Ababa, to determine the normal weight of the Brain in Ethiopian population in the capital city of Ethiopia from September 2016 to April 2017. Method: Total of 902 autopsies were conducted during the study period. All the vital organs in the dead body fulfilling inclusion criteria are dissected as per the standard autopsy protocol and were weighed. Results: Average weight of the Brain in adults was 1272.16 grams, lowest weight was grams, Heaviest Brain was of 1570 grams. These findings were discussed with other references across the globe and conclusions were drawn. Conclusion: Average weight of the Brain Ethiopian population studied is 1287. 5685715 grams, Average weight of the Brain in male 1343.972857 grams, Average weight of the Brain in Female 1231.164286 grams, there is significant difference between Male & Female Brain weights with P value of 0.0039. There is significant rapid loss of Brain weight after 65 years of age.
