The difference between lissencephaly and agyria is agyria is a specific type of lissencephaly which is characterized by the complete absence of gyri which are folds and sulci which are grooves on the brains surface.
Lissencephaly is a broader term for a smooth brain surface and essentially agyria is a severe form or severe type of lissencephaly.
The virus that causes lissencephaly is the CMV virus also known as the Cytomegalovirus.
Genetic mutations are a common cause of Lissencephaly although Cytomegalovirus and other intrauterine viral infections can disrupt the normal nuronal migration during the fetal brain develop and cause lissencephaly.
Lissencephaly is caused by both non genetic and genetic factors and also develops in fetuses between the 12th weeks and 24th weeks of pregnancy.
Lissencephaly is not a cerebral palsy although it can be associated with cerebral palsy.
Lissencephaly is a brain malformation that is characterized by a smooth brain surface which is a result of incomplete neuronal migration during the fetal development.
Cerebral palsy is a group of neurological disorders which affect movement and posture and often stems from brain damage that occurs before birth, during birth or even shortly after birth.
Lissencephaly is a spectrum of severe and rare brain malformations and is caused by non genetic and genetic factors.
Lissencehpahy is a condition that involves a smooth brain surface as a result of a lack of normal brain folds called gyri and grooves called sulci.
The smooth brain surface in Lissencephaly is a result of abnormal neuronal migration during fetal development.
Cerebral palsy is a bread term for a range of neurological conditions which affect a persons movement as well as coordination and can result from various different brain injuries or brain malformations that occur, before, during or even after birth and lead to difficulties with muscle control, posture and movement.
Although lissencephaly is a specific brain malformation, it can also lead to symptoms which also overlap with the symptoms of cerebral palsy, like developmental delays, motor impairments and even seizures.
And so some people with lissencephaly may even initially be diagnosed with cerebral palsy, especially in cases of severe developmental delay and motor issues.
