What is cerebellar vermis hypoplasia?

Cerebellar vermis hypoplasia. Cerebellar vermis hypoplasia is associated with a normal position of the cerebellar vermis relative to the brainstem or minimal upward rotation due to a mildly enlarged fourth ventricle, without elevation of the tentorium.

What is inferior vermian hypoplasia?

INTRODUCTION. Isolated inferior vermian hypoplasia (iiVH) is one of the most common fetal cerebellar anomalies detected by obstetrical ultrasound and presenting for prenatal counselling. 1–3. Despite its prevalence, the long-term neurodevelopmental consequences of iiVH remain poorly defined and controversial.

What does the inferior vermis do?

Functionally, the vermis is associated with bodily posture and locomotion. The vermis is included within the spinocerebellum and receives somatic sensory input from the head and proximal body parts via ascending spinal pathways.

What does the cerebellar vermis do?

midline of the cerebellum; it separates the cerebellum into two cerebellar hemispheres. The vermis is thought to be associated with the ability to maintain upright posture.

What is the meaning of hypoplasia?

Definition of hypoplasia : a condition of arrested development in which an organ or part remains below the normal size or in an immature state.

What is cerebellar hypoplasia caused by?

What causes it? Cerebellar hypoplasia most commonly occurs when a pregnant cat becomes infected with feline panleukopenia virus and passes the infection to her unborn kittens. The panleukopenia virus preferentially attacks rapidly dividing cells.

What causes cerebellar hypoplasia?

Can cerebellar hypoplasia be cured?

There is no cure or treatment for cerebellar hypoplasia, but as noted before, the symptoms will not worsen. With some help, many kittens will learn to live with their disabilities. They should be kept indoors as their ability to protect themselves outside will be greatly compromised.

What is hypoplasia of the brain?

Publications. Definition. Cerebellar hypoplasia is a neurological condition in which the cerebellum is smaller than usual or not completely developed. Cerebellar hypoplasia is a feature of a number of congenital (present at birth) malformation syndromes, such as Walker-Warburg syndrome (a form of muscular dystrophy.

Is cerebellar hypoplasia brain damage?

Cerebellar hypoplasia is a developmental condition in which the cerebellum of the brain fails to develop properly. The cerebellum is the portion of the brain that controls fine motor skills, balance, and coordination. The condition is not painful or contagious.

What are symptoms of cerebellar hypoplasia?

In an infant or young child, symptoms of a disorder that features cerebellar hypoplasia might include floppy muscle tone, developmental or speech delay, problems with walking and balance, seizures, intellectual disability, and involuntary side to side movements of the eyes.

Is cerebellar hypoplasia a disability?

Cerebellar hypoplasia is a developmental anomaly that appears to be either etiologically related to, or a marker for, developmental disability, thus confirming the intact cerebellum’s integral role in normal psychomotor development.

What are the effects of cerebellar hypoplasia?

How is cerebellar hypoplasia treated?

There is no known treatment for this condition. Supportive care may ameliorate symptoms slightly in some cases.

What is isolated cerebellar vermis hypoplasia?

Isolated cerebellar vermis hypoplasia is a rare, non-syndromic cerebellar malformation characterized by an underdeveloped cerebellar vermis.

What is ‘inferior vermian hypoplasia’?

Key point: ‘Inferior vermian hypoplasia’ may actually be due to hypoplasia of other vermian lobules, for example the neovermian lobules, leading to overall reduction in craniocaudal growth. This may explain why in certain cases of ‘inferior vermian hypoplasia’ we may see only cognitive defects.

What is cerebellar hypoplasia (non-human)?

For cerebellar hypoplasia in other animals, see cerebellar hypoplasia (non-human). Cerebellar hypoplasia is characterized by reduced cerebellar volume, even though cerebellar shape is (near) normal.

What is the difference between global and regional cerebellar hypoplasia?

The pattern of volume loss may be regional (affecting only part of the cerebellum) or global. Global cerebellar hypoplasia can appear indistinguishable from diffuse cerebellar atrophy on a single study and can only be distinguished from the latter by demonstrating or implying (clinically) that there has been no change over time 4 .
