Summary

Hydranencephaly survivors can live longer than expected, with one case reaching over 20 years. This study compares long-term survivors and discusses implications for minimally conscious states.

Area of Science:

  • Neurology
  • Developmental Biology
  • Medical Case Studies

Background:

  • Hydranencephaly is a severe congenital brain malformation characterized by the absence of cerebral hemispheres.
  • Typical prognosis involves limited survival, often not exceeding infancy.

Observation:

  • Two previous cases reported hydranencephaly survival beyond 10 years of age.
  • This report details the oldest known survivor, a 20-year-old individual with hydranencephaly.

Findings:

  • Comparative analysis of behavioral and anatomical features of three long-term hydranencephaly survivors.
  • Detailed case study of a 20-year-old individual with hydranencephaly, extending known survival limits.

Implications:

  • Discussion of hydranencephaly in the context of the minimally conscious state (MCS).
