• Developmental Delay

  Mild developmental delay is characterized by motor and neurological development that is no greater than 2 standard deviations below average for the age of the child, and moderate delay is characterized by greater than 2 standard deviations below. [en.wikipedia.org]

  Clinical Picture of Hydrocephalus Symptoms For infants with hydrocephalus, the first symptom is usually an enlarged head with failure to thrive and developmental delays. [lecturio.com]

  WWS is associated with generalized hypotonia, muscle weakness, developmental delay with mental retardation and, in some children, seizures. [slideshare.net]

  The development of the sylvian fissure is one of the major brain maturational processes occurring in fetal life, and abnormalities in this process are frequent in children with developmental delay. [clinicalgate.com]

• Developmental Disorder

  Tethered cord: Abnormal attachment and scarring of the spinal cord or its coverings (meninges) can occur as the result of a developmental disorder such as a small mass of fatty tissue, a tight filum terminale or a midline bone spur. [chiariproject.org]

• Abnormal Behavior

  In adults, the complaints are usually headache, nausea, vomiting, vision abnormalities, behavioral changes and sometimes confusion and disturbed conscious level in acute cases. [lecturio.com]

• Stroke

  Causes can include head injuries, strokes, infections, tumors, and bleeding in the brain. [icdlist.com]

  This is a common sequel of wasting brain diseases (leukodystrophies, multiple sclerosis, multiple strokes, Alzheimer's disease, Huntington's disease, etc.). [neuropathology-web.org]

• Paresthesia

  Paresthesia: Abnormal sensation such as numbness, prickling and tingling. Paucity: Smallness or lower in number. Peduncle: Stalk-like structures in the brain connecting different functioning areas. [chiariproject.org]

  The pain and paresthesia in the right legalmost disappeared, and walking improved to the extent that the patient was able toascend stairs unaided. [flickr.com]

  The L1 syndrome encompasses the following 4 phenotypes: HSAS (X-linked hydrocephalus with stenosis of the aqueduct of Sylvius) MASA (mental retardation, adducted thumbs, shuffling gait, and aphasia) SPG1 (X-linked complicated hereditary spastic paraplegia [neuropathology-web.org]

• Nystagmus

  Nystagmus: Constant, involuntary, cyclical movement of the eyeball. Movement may be in any direction; i.e. sideways, up, down or rotatory. May be present continually or only with looking in a certain direction. [chiariproject.org]

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. [icdlist.com]

Treatment ranges from observation to surgical intervention, depending on severity and progression of symptoms. Hydrocephalus is the most common cause of abnormally large heads in neonates. [merckmanuals.com]

On the other hand, those with mild isolated ventriculomegaly of less than 12 mm have an excellent prognosis. [chop.edu]

Holoprosencephaly is one of the most severe disorders of ventral induction; it features incomplete separation of the cerebral hemispheres and has a very severe prognosis in most cases. [obgyn.mhmedical.com]

Prognosis was favorable in group A, while cases in groups B, C, D and E showed poor seizure prognosis. [jstage.jst.go.jp]

Treatment and prognosis Treatment is often either with a third ventriculostomy or VP shunting. There is small recurrence risk (~4%) for congenital cases even when it is not X linked. Promoted articles (advertising) [radiopaedia.org]

In adults, as an acquired abnormality, AS has different etiologies and thus different demographics related to them. The clinical presentation depends on the severity and age of presentation as well as whether or not it is X-linked. [radiopaedia.org]

Etiology Several factors are implicated in the etiology of hydrocephalus in children with myelomeningocele, including the following: A degree of aqueductal stenosis Anomalous venous drainage in the posterior fossa caused by compression of the sigmoid [emedicine.medscape.com]

Group D was characterized by 1) symptomatic etiology, 2) a lower incidence of family history, 3) a higher incidence of early onset within the first 6 months, and 4) poor prognosis for mental and physical development and seizures. [jstage.jst.go.jp]

The goals of surgery are to preserve neural function, to prevent infection, and to prevent long-term complications such as an epidermal or dermal inclusion cyst and cord tethering. [1] For patient education information, see the Brain and Nervous System [emedicine.medscape.com]
