Young man with rare condition who was born without a brain celebrates 20 years in the USA
A young American born with hydranencephaly, a rare condition that prevents the formation of the cerebral hemispheres, celebrated her 20th birthday in Omaha, Nebraska, in early November 2025. Alex Simpson, diagnosed at two months old, surpassed the medical prediction of not living beyond four years. The family attributes its longevity to the welcoming environment and daily care. The story was featured in The Mirror US.
Hydranencephaly, a congenital anomaly of the central nervous system, results in the absence of both halves of the brain, responsible for vital functions. Unlike hydrocephalus, which involves fluid accumulation, Alex’s condition is marked by abnormal fetal development. According to the Cleveland Clinic, most babies with hydranencephaly do not survive their first year.
- 24-hour care is essential for the young woman.
- The family adjusts routines to meet their needs.
- Physical contact strengthens emotional bonds with Alex.
The young woman depends on constant supervision, with support from her parents, brother and other relatives. The condition requires daily adaptations to ensure your well-being.
Rare Condition Details
Hydranencephaly is a brain malformation detected by prenatal ultrasound or MRI. The absence of the cerebral hemispheres causes symptoms such as muscle stiffness, breathing difficulties and vision and hearing problems.
Scientists associate the condition with genetic factors or exposure totoxins during pregnancy, but the exact causes remain uncertain. The disease has no cure, and treatments focus on alleviating symptoms.
Intensive care and family support
Alex’s family organizes shifts to provide continuous care. The brother, S.J., 14 years old, highlights the importance of physical contact for connecting with the young girl.
The parents adapted the house to meet Alex’s special needs, including medical equipment. The routine includes physiotherapy sessions and nutritional support.
Available treatments
The management of hydranencephaly involves surgery to implant valves that drain brain fluid, reducing intracranial pressure. Anticonvulsant medications help control seizures.
Physical therapy is used to improve muscle tone and mobility. Nutritional support ensures the patient’s overall health.
Complementary therapies, such as music therapy, are explored by some families. Cleveland Clinic recommends multidisciplinary follow-up.
Prognosis and challenges
Babies with hydranencephaly face a serious prognosis, with highmortality before or shortly after birth. Alex’s survival for two decades is considered exceptional.
The condition requires constant medical monitoring to prevent complications. Intracranial pressure can cause discomfort, requiring regular interventions.
Patient families face emotional and financial challenges. Psychological support is recommended to deal with the demands of care.
Palliative care is common in serious cases, prioritizing quality of life. Alex’s story inspires other families.
Story Impact
Alex Simpson’s trajectory gained attention for defying medical expectations. Her story highlights the importance of family support and advances in palliative care.
Organizations supporting rare conditions have used the case to raise public awareness. The family plans to share more about their experience at local events.
