Craniosynostosis - Alopecia - Brain Defect is a rare disorder characterized by early fusion of the skull bones, lack of hair at birth and problems with brain function. Early fusion of the skull bones can lead to problems with brain development, leading to certain brain defects. Individuals with this disorder are more prone to problems with motor coordination, and thus problems with basic tasks, such as walking and sitting. Individual may also have problems with reasoning and solving problems, as well as performing day-to-day tasks. The disorder is often diagnosed early in childhood, since the symptoms are very apparent. Slow mastering of basic tasks, and having difficulty remembering things may also suggest this disorder in children. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. If the brain defect is treatable, doctors may suggest individuals undergo brain surgery to fix the problem.
