Factors Influencing Head Size
Several factors can contribute to the size of a person's head. Here are some key causes:
-
Benign Familial Macrocephaly: This is a genetic condition where having a larger head runs in the family. It's generally not harmful.
-
Canavan Disease: This is a rare, inherited neurological disorder that affects how the body processes aspartic acid, a type of protein. This can lead to an enlarged head size.
-
Hydrocephalus: This condition involves a buildup of fluid inside the skull, which causes the brain to swell and can increase head circumference.
