Treatment
Treatment with amisulpride 1200 mg/day resulted in a 30% decrease in PANSS score within 2 months. Then galantamine 8 mg/day was added and PANSS score decreased further by 27% within 2 weeks. [ncbi.nlm.nih.gov]
[…] of the newborn a few hours after with cPMP through a central line with good results.8 After a daily treatment with cPMP, the patient manifested an almost normal neurodevelopment.8 Lubout et al published a case where the treatment is administered shortly [dovepress.com]
Prognosis
In general isolated mild cisterna magna enlargement ( between 10 to 13 mms ) is associated with good prognosis in the child after birth. [kriznanultrasoundimages.com]
We conclude that overall, the prognosis for these posterior fossa defects is grim but not uniformly fatal. The presence of other anomalies is associated with the worst prognosis. [childnervoussystem.blogspot.com]
One set of data indicates that nearly 80% of parents prefer to abort fetuses identified with PFAs in some parts of the world.1 This may be unwarranted, given that cases of isolated MCM have a favorable developmental prognosis. [consultant360.com]
The prognosis for mega cisterna magna is good when the condition occurs with normal ventricles in an isolated finding. It is usually observed on a CT/MRI or ultrasound. [reference.com]
Prognosis: Normal neurodevelopment. Recurrence: No increased risk of recurrence. [fetalmedicine.org]
Etiology
It is not known whether this association is accidental or based on etiological commonality. The purpose of this case report is to review the relationship between the cerebellum and psychiatric symptoms and to contribute to the literature. [koreascience.kr]
Rarely, both of these conditions may have a common underlying etiology that may indicate a causal relationship. Further studies are required to establish a causal relationship between the mega cistern magna and the psychiatric disorders. [docksci.com]
The etiology of the disease is speculated to be the loss of Zic1/4 genes. Conclusion: This is a case of DWS managed conservatively, with surgery being the usual treatment of choice. [austinpublishinggroup.com]

Pathophysiology
Discussion Considering the pathophysiology of KLS, the hypothalamic hypo-metabolism may implicate sleep regulation, control of food intake, and sexual behavior. [scirp.org]

[…] role in coordination and motor functions.1 Besides its involvement in motor and vestibulo-ocular regulation, it is considered to be involved in modulation of mood.2 Cerebellar structures, especially the vermis, are considered to be associated with the pathophysiology [ncbi.nlm.nih.gov]
Pathophysiology: Dandy-Walker malformations are formed during embryogenesis. Insults of varying severity to both the developing cerebellar hemispheres and fourth ventricle currently are believed to be the genesis of the anomaly. [medicaljournal.blogspot.com]
