Dicephalic

Dicephalic refers to a rare congenital condition where an individual has two heads. This condition is a form of conjoined twinning, specifically a type of partial duplication. In dicephalic twins, the two heads share a single torso, and often a single set of organs below the neck, although variations can occur. The degree of separation can vary, with some individuals having two distinct necks and shoulders, while others are more fused.

The development of dicephaly occurs early in embryonic development when a single fertilized egg begins to split into two embryos, but the separation process is incomplete. The exact cause is not fully understood, but it is believed to be a random event. The survival rates for dicephalic individuals are generally low due to the complex medical challenges associated with the condition.

Individuals with dicephaly often face significant health issues, including developmental delays, organ deficiencies, and mobility challenges. Despite these difficulties, some dicephalic individuals have lived for many years, demonstrating remarkable resilience. Medical care for dicephalic individuals is highly specialized, focusing on managing their unique health needs and improving their quality of life. The condition is distinct from having identical twins, as dicephalic individuals are a single organism with duplicated heads.
