Clinical definition: Lissencephaly, literally meaning smooth brain, is a rare genetic brain malformation. Kids with Lissencephaly usually have significant developmental delays, seizure disorders, spasticity (stiff muscles), hypotonia (floppy muscles), difficulty swallowing, aspiration, and respiratory issues. Although there is a wide spectrum and some children have a near normal development. In most cases, signs of lissencephaly develop in pregnancy between 12 and 14 weeks. At this time, the nerve cells in the brain would usually relocate to different parts of the brain but in cases of lissencephaly, the nerve cells do not move and this has an impact on development. Symptoms of lissencephaly Lissencephaly (LIS) (derived from the Greek words lissos meaning smooth and enkephalos meaning brain) is a neuronal migration disorder characterized by absent (agyria) or decreased (pachygyria) convolutions, producing a smooth cerebral surface. Several different types of LIS have been recognized Lissencephaly type I, also known as classic lissencephaly, is a heterogeneous group of disorders of cortical formation characterized by a smooth brain, with absent or hypoplastic sulci and is strongly associated with subcortical band heterotopia (see classification system for cortical malformations) and therefore the term lissencephaly type I - subcortical band heterotopia spectrum is probably. Lissencephaly, which literally means smooth brain, is a rare, gene-linked brain malformation characterized by the absence of normal convolutions (folds) in the cerebral cortex and an abnormally small head (microcephaly).

Lissencephaly is characterized by a thickened cortex and the absence of folds or gyri (agyria) or the presence of abnormally wide gyri (pachygyria). Lissencephalies can present in different forms and with varying severity, ranging from complete agyria to mixed agyria and pachygyria, or simplified gyri with subcortical band heterotopia (double. Lissencephaly (LIS) and subcortical band heterotopia (SBH) are malformations resulting from anomalies in cortical neuronal migration. LIS is characterized by absent (agyria) or decreased (pachygyria) convolutions, producing cortical thickening and a smooth cerebral surface. SBH is a related disorder in which bands of gray matter are interposed. Lissencephaly is further characterized by microcephaly (reduced head size) and by symptoms such as muscle spasms, seizures, abnormal facial expressions, failure to thrive, and deformation of the hands, fingers, or toes Lissencephaly Symptoms and Signs Signs of lissencephaly may be difficulty in swallowing, abnormal facial features, and psychomotor retardation. Lissencephaly Causes Lissencephaly may be a result of viral infections in the fetus during its first three months of development. It can also be because of insufficient supply of blood in the fetal.

Know the causes, symptoms, treatment, prognosis and life expectancy of Holoprosencephaly These patients had both computed tomographic (CT) scan and magnetic resonance imaging (MRI) evidence of marked migrational central nervous system defects consistent anatomically with the spectrum of lissencephaly-pachygyria, a disorder commonly idiopathic or associated with chromosomal abnormalities or with unknown early gestational insults Lissencephalies and subcortical band heterotopia (SBH) are a group of cerebral malformations involving arrest of neuronal migration during embryogenesis. Lissencephaly is characterized by simplification or absence of the brain convolutions, resulting in a smooth appearance. SBH, also known as double cortex, is characterized by abnormal bands of neurons beneath a normal cortex Porencephaly is a structural abnormality of the brain. It may manifest before or after birth. It has many causes. For instance, it can appear after a brain injury. Stroke, bleeding, or infection can cause the brain injury. In porencephaly, CSF fills the injured area. This creates the fluid-filled cyst
X-linked Lissencephaly is an inherited disease in which the cerebral cortex, which should normally have grooves and folds, is smooth. This abnormally smooth surface of the brain causes patients who have X-linked Lissencephaly to have mental and developmental problems, muscle weakness, seizures, and other problems Neuronal migration disorders include lissencephaly as part of the agyria-pachygyria-band spectrum, cobblestone lissencephaly, periventricular heterotopia, and other variants such as Zellweger and Kallman syndrome. Patients may have only focal collections of abnormally located neurons known as heterotopias
