What is hypoplasia of the corpus callosum?
Sometimes it is the middle or front part that is missing instead. Hypoplasia of the corpus callosum. This is when all parts of the corpus callosum form, but the entire structure is very thin or very small. Corpus callosum abnormality due to hydrocephalus.
What causes hypoplasia of the corpus callosum?
It can be part of several genetic syndromes, such as Aicardi syndrome, Andermann syndrome and Apert syndrome, trisomies 13, 18; or result from metabolic causes; drugs (cocaine); or viral infection (influenza). Many patients with corpus callosum anomalies have other brain anomalies, including white matter hypoplasia.
What happens when the corpus callosum is underdeveloped?
Individuals with a disorder of the corpus callosum typically have delays in attaining developmental milestones such as walking, talking, or reading; challenges with social interactions; clumsiness and poor motor coordination, particularly on skills that require coordination of left and right hands and feet (such as …
What is an example of corpus callosum?
For example, when you type on your keyboard, information about the feel of the keys is sent up from your right hand to the primary somatosensory cortex on the left side of your brain. That information, however, must then be shared with the right side of your brain as well.
Why the corpus callosum is important?
The two hemispheres in your brain are connected by a thick bundle of nerve fibres called the corpus callosum that ensures both sides of the brain can communicate and send signals to each other.
How does the corpus callosum affect memory?
These findings suggest that the corpus callosum facilitates more efficient learning and recall for both verbal and visual information, that individuals with AgCC may benefit from receiving verbal information within semantic context, and that known deficits in facial processing in individuals with AgCC may contribute to …
What happens if the corpus callosum is damaged?
The corpus callosum joins the two parts of the brains together. When severed or damaged, communication between the two parts is inhibited, causing problems if a situation requires the two parts of the brain to work in unison.
What causes agenesis of the corpus callosum?
Agenesis of the Corpus Callosum (ACC) is a congenital defect in which the corpus callosum is either absent or not completely formed. ACC is caused by disruption of brain development during the prenatal period. Corpus Callosum Agenesis can occur alone or in conjunction with other brain defects.
Is agenesis of corpus callosum hereditary?
However, agenesis of corpus callosum can be inherited as an autosomal recessive trait or an X-linked dominant trait. This disorder may also be due in part to an infection during pregnancy (intrauterine) leading to abnormal development of the fetal brain.
What is agenesis of the corpus callosum (ACC)?
Agenesis of the corpus callosum (ACC) is a rare birth defect (congenital disorder) in which there is a complete or partial absence of the corpus callosum. It occurs when the corpus callosum, the band of white matter connecting the two hemispheres in the brain, fails to develop normally, typically during pregnancy.
