The cerebellum helps regulate dynamic musclular activities such as dancing or playing musical instruments or complex movements of the tongue and vocal muscles.

BBC - Health - Conditions - Joubert Syndrome Joubert syndrome (also known as cerebellar vermis agenesis or cerebelloparenchymaldisorder IV) is a rare inherited disorder of the brain. http://www.bbc.co.uk/health/conditions/joubert1.shtml
Extractions: Normally the cerebellum (an area at the back of the brain which plays an important part in the control of balance and co-ordination) has two interconnected halves or hemispheres. However, in Joubert syndrome the connection between the two hemispheres of the cerebellum, known as the cerebellar vermis, fails to develop. As a result, one of the main features of Joubert syndrome is poorly controlled or unsteady movement, known as ataxia. Another area of the brain called the brain stem, which controls basic functions such as breathing, is also malformed. This results in an abnormal rapid breathing pattern, especially in very early childhood. An affected baby may pant or breath rapidly for a while (this is known as episodic tachypnoea) and then stop breathing (this is called apnoea). Many other features have also been described in Joubert syndrome (see the box below). The condition is diagnosed on the basis of physical features, symptoms and an MRI scan of the brain which shows typical abnormalities, including one in which some of the brain structures form the characteristic shape of a molar tooth.

Extractions: Search our online shop A B C D ... Z Seizures in which jerking spasms occur in one part of the body, sometimes spreading quickly to other areas, usually without loss of consciousness. The seizures occur in the part related to the irritated area of the brain and are due to a lesion in the cerebral cortex. (See also Epilepsy) Yellowness of the skin and tissues, best seen in the eyes by natural light. Due to an excess of bile pigment in the tissues. A condition in which the third and fifth cranial nerves are abnormally connected. One of the functions of the third nerve is the opening of the eyelid. As one of its functions, the fifth nerve controls the jaw muscles. In this disorder, the eyelid droops (ptosis) and opens when the jaw is moved. If the ptosis is severe or persistent, an operation to lift the eyelid may be necessary. A feature of some multiple abnormality syndromes. Features include: nystagmus, ataxia, alternating hyperpnoea (rapid breathing) and apnoea (cessation of breathing), lax muscle tone, learning difficulty. Due to failure of development of the vermis (a small structure within the cerebellum). Cause not established.

Extractions: Return to Index Last update: 7/26/02. This page is meant to provide a general outline of cerebellar disorders. More specific and detailed material is found in links. The cerebellum is part of the brain. It lies under the cerebrum, towards the back, behind the brainstem and above the brainstem. The cerebellum is largely involved in "coordination". Persons whose cerebellum doesn't work well are generally clumsy and unsteady. The main clinical features of cerebellar disorders include incoordination, imbalance, and troubles with stabilizing eye movements. There are two distinguishable cerebellar syndromes midline and hemispheric. Midline syndromes are characterized by imbalance. Persons are unsteady, they are unable to stand in Romberg with eyes open or closed, and are unable to well perform tandem gait. Severe midline disturbance causes "trunkal ataxia" a syndrome where a person is unable to sit on their bed without steadying themselves. Some persons have "titubation" or a bobbing motion of the head or trunk. Midline cerebellar disturbances also often affect eye movements. There may be nystagmus, ocular dysmetria and poor pursuit. Hemispheric cerebellar syndromes are characterized by incoordination of the limbs. There may be decomposition of movement, dysmetria, and rebound. Dysdiadochokinesis is the irregular performance of rapid alternating movements. Intention tremors may be present on an attempt to touch an object. A kinetic tremor may be present in motion. The finger-to-nose and heel-to-knee tests are classic tests of hemispheric cerebellar dysfunction. While reflexes may be depressed initially with hemispheric cerebellar syndromes, this cannot be counted on. Speech may be dysarthric, scanning, or have irregular emphasis on syllables.

Extractions: The Center for Cerebellar Malformations CCM Home Contact us Dandy Walker Malformation The Dandy-Walker malformation was first described in 1887 by Sutton (Sutton, 1887) and was further characterized by Dandy and Blackfan in 1914 and Taggart and Walker in 1942 (Dandy and Blackfan, 1914; Taggart and Walker, 1942) . The key components of this malformation include hypoplasia of the cerebellar vermis and cystic dilatation of the 4th ventricle. The 4th ventricle communicates with a retrocerebellar cyst that may cause enlargement of the posterior fossa and elevation of the tentorium, seen on imaging studies as elevation of the torcula or confluence of the sinuses. A third, variable component of DWM is communicating hydrocephalus with enlarged lateral ventricles. Presentation of DWM can take many forms. It often presents with macrocephaly in the neonatal period, and infants may come to medical attention because of hydrocephalus, developmental delay, or ataxia. It may be identified on prenatal ultrasound, where prenatal counseling takes a critical role. It may be present in asymptomatic individuals undergoing brain imaging for an unrelated reason.
