Microcephaly generally is due to the diminished size of the largest part of the human brain, the cerebral cortex, and the condition can arise during embryonic and fetal development due to insufficient neural stem cell proliferation, impaired or premature neurogenesis, the death of neural stem cells or neurons, or a combination of these factors ...
Holoprosencephaly is typically diagnosed during fetal development when there are abnormalities found on fetal brain imaging, but it can also be diagnosed after birth. The protocol for diagnosis includes neuroimaging ( Ultrasound or fetal MRI prior to birth or Ultrasound, MRI or CT post birth), syndrome evaluation, cytogenetics , molecular ...
Waardenburg syndrome has multiple different types with some variations in symptoms, and symptoms can vary among those with the same type. The two features consistent across all types of Waardenburg syndrome are some degree of congenital sensorineural hearing loss and some degree of pigmentation deficiencies, most consistently in the eyes.
This may bring into question the effectiveness of brain development studies in treating and successfully rehabilitating criminal youth. [9] It's a common misconception to believe the brain stops development at any specific age. In the 2010s and beyond, science has shown that the brain continues to develop until at least 30 years of age. [10]
Band heterotopia, a form of the condition (also known as double cortex syndrome), [6] is seen exclusively in women; men with a mutation of the related gene (called XLIS or DCX) usually die in utero or have a much more severe brain anomaly. Symptoms in affected women vary from normal to severe developmental delay or intellectual disability; the ...
Someone with PRES may experience headaches, changes in vision, and seizures, with some developing other neurological symptoms such as confusion or weakness of one or more limbs. The name of the condition includes the word "posterior" because it predominantly, though not exclusively, affects the back of the brain (the parietal and occipital lobes).
Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development. [1] It is a cephalic disorder that results from a neural tube defect that occurs when the rostral (head) end of the neural tube fails to close, usually between the 23rd and 26th day following conception.
