Mental Deterioration
If left untreated, blindness and continuing mental deterioration may occur. [14] [15] [16] Hydrocephalus may be subdivided according to the particular defect that exists in the brain and whether the cerebrospinal fluid pressure is high or normal: [14] [rarediseases.info.nih.gov]

With treatment, many people lead normal lives with few limitations. Treatment usually involves surgery to insert a shunt. A shunt is a flexible but sturdy plastic tube. [medlineplus.gov]
Prognosis
[ edit ] The prognosis of megalencephaly depends heavily on the underlying cause and associated neurological disorders. [18] Because the majority of megalencephaly cases are linked with autism, the prognosis is equivalent to the corresponding condition [en.wikipedia.org]
[…] non-syndromic macrodystrophia lipomatosa syndactyly : most common associated limb anomaly, it is then termed polysyndactyly If it is an isolated anomaly it is incidental and not of concern but if associated with another anomaly it then carries a vastly variable prognosis [radiopaedia.org]

Etiology
Megalencephaly and hemimegalencephaly: breakthroughs in molecular etiology. [ncbi.nlm.nih.gov]
(Etiology) Megalencephaly-Polymicrogyria-Polydactyly-Hydrocephalus Syndrome may be caused by mutation(s) in PIK3R2, AKT3 or CCND2 gene Each gene codes for proteins involved in an important cellular chemical signaling pathway, known as the PI3K-AKT-mTOR [dovemed.com]
Older age at the time of the procedure (eg, greater than one year of age) was by far the strongest predictor of success, and noninfectious etiologies (eg, myelomeningocele, intraventricular hemorrhage, aqueductal stenosis, or tectal tumor) and lack of [es.slideshare.net]
Megalencephaly is classically defined into 3 groups, according to the etiology: idiopathic or benign, metabolic, and anatomic (Fig. 1). [journals.lww.com]
Conclusions A combination of genetic and biochemical methods was able to identify the involvement of the mTOR pathway in approximately 70% of patients with megalencephaly of an unknown etiology. [bmcmedgenet.biomedcentral.com]

In most cases, those diagnosed with this type of megalencephaly usually do not survive through adulthood. [20] Epidemiology [ edit ] Approximately one out of every 50 (2%) children in the general population are said to have megalencephaly. [3] Additionally [en.wikipedia.org]

Pathophysiology
Hydrocephalus occurs in 90 % of children with Dandy-Walker malformation/variant The pathophysiology of the hydrocephalus is now felt to be multifactorial. [es.slideshare.net]
Pathophysiology [ edit ] One impact of megalencephaly is the complete lack of motor development. [en.wikipedia.org]
Prevention
Mutations in the AKT3, CCND2, or PIK3R2 gene increase the activity of their respective proteins or prevent the proteins from being broken down when they should. [ghr.nlm.nih.gov]
