Spina bifida Anencephaly is a serious birth defect in which a baby is born without parts of the brain and skull. It is a type of neural tube defect (NTD).These are birth defects that happen during the first month of pregnancy, usually before a woman knows she is pregnant.nencephaly happens if the upper part of the neural tube does not close all the way. This often results in a baby being born without the front part of the brain (forebrain) and the thinking and coordinating part of the brain (cerebrum). The remaining parts of the brain are often not covered by bone or skin.

- Anencephaly is a condition that prevents the normal development of the brain and the bones of the skull.This condition results when a structure called the neural tube fails to close during the first few weeks of embryonic development.Anencephaly facts medical author: Melissa Conrad Stoeppler, STöPPLER. 1  Md anencephaly is an example of a neural tube, defect a condition that results from an error in the first weeks of embryonic. 2  Development in, anencephaly the bones of the skull and brain do not develop.  properly

- Mental retardation (MR) is a condition diagnosed before age 18, usually in infancy or prior to birth, that includes below-average general intellectual function, and a lack of the skills necessary for daily living. When onset occurs at age 18 or after, it is called dementia, which can coexist with an MR diagnosis.eviations in normal adaptive behaviors depend on the severity of the condition. Mild retardation may be associated with a lack of curiosity and quiet behavior. Severe mental retardation is associated with infantile behavior throughout life.

MICROCEPHALY WITH OR WITHOUT CHORIORETINOPATHY, LYMPHEDEMA, OR MENTAL RETARDATION; MCLMR Description. Microcephaly with or without chorioretinopathy, lymphedema, or mental retardation is an autosomal dominant disorder that involves an overlapping but variable spectrum of central nervous system and ocular developmental anomalies.

Craniotomy Aneurysm clipping is another surgical procedure which may require a craniotomy. A cerebral aneurysm (also called an intracranial aneurysm or brain aneurysm) is a bulging weakened area in the wall of an artery in the brain, resulting in an abnormal widening or ballooning. craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap.

What is Aphasia? Aphasia is a communication disorder that affects a person’s ability to process and use language. It is a neurological condition caused by damage to the portions of the brain responsible for language, and it does not affect intelligence.phasia is a communication disorder that affects a person’s ability to process and use language.

Spina bifida Neural tube defects (NTDs) are among the most common birth defects contributing to infant mortality and serious disability. NTDs, which include anencephaly, spina bifida, and encephalocele, occur in approximately 1 of 1000 births in the United States. An estimated 4000 pregnancies are affected with NTDs each year.

Anencephaly As a result, people with anencephaly are missing large parts of the brain called the cerebrum and cerebellum. These brain regions are necessary for thinking, hearing, vision, emotion, and coordinating movement. The bones of the skull are also missing or incompletely formed.

Hydranencephaly Causes Hydranencephaly is an extreme form of porencephaly, which is characterized by a cyst or cavity in the cerebral hemispheres. Although the exact cause of hydranencephaly remains undetermined in most cases, the most likely general cause is by vascular insult such as stroke or injury, intrauterine infections, or traumatic disorders after the first trimester of pregnancy.

Porencephaly Porencephaly is a rare congenital disorder that results in cystic degeneration and encephalomalacia and the formation of porencephalic cysts.or the purpose of this article the term porencephaly is taken to mean the following: a cystic lesion of the brain due to an encephaloclastic insult (e.g. intrauterine infections and ischaemia), lined by white matter, which communicates with the ventricles and/or the subarachnoid space.

- Cerebral palsy (CP) is a disorder that affects muscle tone, movement, and motor skills (the ability to move in a coordinated and purposeful way). CP usually is caused by brain damage that happens before or during a baby's birth, or during the first 3 to 5 years of a child's life. This brain damage also can lead to other health issues, including vision, hearing, and speech problems; and learning disabilities.

Autistic disorder Autistic disorder (also called autism; more recently described as mindblindedness) is a neurological and developmental disorder that usually appears during the first three years of life. A child with autism appears to live in his/her own world, showing little interest in others, and a lack of social awareness.

What is Cephalization? Cephalization refers to an evolutionary trend by which the neurons of an organism are concentrated towards one end of the body.The neurons become concentrated in the head region and allows the brain of the organism to be situated in one place.Cephalization is beneficial because it allows a complex brain to be developed. Together with the bilateral body plan, a complex brain enables an organism to make complex and quick movements.asically, cephalization is the process which enables organisms to have a brain. At an intermediate level of this process, organisms may also possess ganglia, which refer to groups of nerve cells or mini control centers that are scattered throughout their bodies.

Hydranencephaly: Definition, Information, Diagnosis & Prognosis Definition: Hydranencephaly. Hydranencephaly is defined as the congenital absence of the cerebral hemispheres in which the space in the cranium that they normally occupy is filled with fluid. Hydranencephaly is a neurologic disorder in which the cerebral hemispheres are lacking although the cerebellum, brainstem, and other central nervous system tissues may be intact. The newborn with hydranencephaly may have normal neurologic functions but does not develop, and computed tomographic scans indicate an absence of cerebral tissue.

Pachygyria Pachygyria (from the Greek pachy meaning thick or fat gyri) is a congenital malformation of the cerebral hemisphere.It results in unusually thick convolutions of the cerebral cortex.ne of the best known and most common types of neuronal migration disorders is lissencephaly, a diffuse cortical malformation relating directly to agyria and pachygyria. Incomplete neuronal migration during the early fetal brain development is the precursor to lissencephaly.

Schizencephaly Imaging Schizencephaly is an uncommon disorder of neuronal migration characterized by a cerebrospinal fluid–filled cleft, which is lined by gray matter. The cleft extends across the entire cerebral hemisphere, from the ventricular surface (ependyma) to the periphery (pial surface) of the brain.

Anencephaly Anencephaly is a condition present at birth that affects the formation of the brain and the skull bones that surround the head. Anencephaly results in only minimal development of the brain.nencephaly is a type of neural tube defect that occurs in about one of 10,000 pregnancies in the U.S. each year. The actual number is unknown because many of these births result in miscarriages. According to the CDC, one in every 4,859 newborns in the United States has this condition.

Holoprosencephaly Holoprosencephaly is caused by a failure of the embryo's forebrain to divide to form bilateral cerebral hemispheres (the left and right halves of the brain), causing developmental defects of the face and in brain structure. Holoprosencephaly has three classifications.
