This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
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 ...
Some patients do not show most of the symptoms related to colpocephaly, such as psychomotor abnormalities and agenesis of the corpus callosum. In some cases, signs appear later on in life and a significant number of children only develop minor disabilities. The following list includes common symptoms of colpocephaly. [3] [4] [5]
Sexual development is thought to be unaffected, as evidenced by a single reported case of a woman with Angelman syndrome conceiving a female child who also had Angelman syndrome. [41] The majority of those with AS achieve continence by day and some by night. Angelman syndrome is not a degenerative syndrome, and thus people with AS may improve ...
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.

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 ...
Macrocephaly is a condition in which circumference of the human head is abnormally large. [1] It may be pathological or harmless, and can be a familial genetic characteristic. . People diagnosed with macrocephaly will receive further medical tests to determine whether the syndrome is accompanied by particular disorde
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]
