Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.
Hypoplasia predominates at the lower part of the pons. Vermis hypoplasia is very variable, severe in patient 13, very slight in patient 10-11-12 and also predominates at the inferior part. B. Coronal images showing varying degrees of cerebellar hemispheric (one of two halves of a part of the brain) hypoplasia. Hemispheres are frequently asymmetric.
Mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH) – also known as mental retardation, X-linked, syndromic, Najm type (MRXSNA); X-linked intellectual deficit, Najm type; intellectual developmental disorder, X-linked, syndromic, Najm type; X-linked intellectual disability–microcephaly–pontocerebellar hypoplasia syndrome; and by variations of these terms ...
Those generally considered to be at greatest risk for PVL are premature, very low birth-weight infants. It is estimated that approximately 3-4% of infants who weigh less than 1,500 g (3.3 lb) have PVL, and 4-10% of those born prior to 33 weeks of gestation (but who survive more than three days postpartum) have the disorder.

Cerebellar hypoplasia is characterized by reduced cerebellar volume, even though cerebellar shape is (near) normal. It consists of a heterogeneous group of disorders of cerebellar maldevelopment presenting as early-onset non–progressive congenital ataxia, hypotonia and motor learning disability.
The European Leukodystrophy Association also supports research into leukodystrophy. As of 2020, more than 387 research projects have been funded. Each year, ELA invites the international scientific community to submit research projects in the field of genetic leukodystrophies, the cerebral white matter in premature infants, and of myelin repair ...
Infantile cerebral and cerebellar atrophy with postnatal progressive microcephaly is a rare hereditary autosomal recessive malformation syndrome of the central nervous system characterized by profound motor delays and intellectual disabilities, progressive microcephaly, hypertonia, spasticity, clonus and epilepsy. MRI findings include severe ...
Maternal toxemia – toxin within circulatory system of mother that is transferred to fetus, causing brain damage; Cerebral hypoxia – reduced oxygen concentration within blood system; Vascular occlusion – blood clotting of vessels; Cystic periventricular leukomalacia; Cerebral atrophy – decrease in neuron number and size and loss of brain ...
