Catatonia
  • This syndrome has been described in association with schizophrenia, obsessive-compulsive disorder, manic episode, psychosis (delusional type), and recurrent catatonia.[ncbi.nlm.nih.gov]
  • Bush Francis catatonia rating scale was administered to determine the severity of catatonia, which gave a score of 23/69 at admission. The patient was started on risperidone 3 mg/day.[neuro.psychiatryonline.org]

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]
  • Abstract The mega cisterna magna is a congenital developmental malformation which in the majority of instances is symptomless and does not require further study or surgical treatment.[ncbi.nlm.nih.gov]

Prognosis

  • 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]
  • In general isolated mild cisterna magna enlargement ( between 10 to 13 mms ) is associated with good prognosis in the child after birth .[kriznanultrasoundimages.com]
  • Prognosis: Normal neurodevelopment. Recurrence: No increased risk of recurrence.[fetalmedicine.org]

Etiology

  • 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.[neuro.psychiatryonline.org]

  • CT scanning also is useful in Dandy-Walker malformation, since it can distinguish between hydrocephalus associated with Dandy-Walker and hydrocephalus with other etiologies.[medicaljournal.blogspot.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]
  • […] 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]
