Macrocephaly remains the main sign of GA1 for those who have no relatives with GA1 and have not been included in a population screening program. GA1 is considered a treatable disease. Two-thirds of the patients who have GA1 encephalopathy will receive little benefit from the treatment for GA1 but can benefit from treatments given to victims of middle cerebral artery occlusion, AIDS dementia and other basal ganglia disorders: brain implants, stem cell neurorestoration, growth factors, monoaminergic agents, and many other neurorehabilitation strategies.
