What happens when cerebellum is damaged?
Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait …
What is hypoplasia of the cerebellum?
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.
What causes atrophy of the cerebellum?
Cerebellar degeneration can be caused by a variety of factors including inherited gene changes ( mutations ), chronic alcohol abuse, and paraneoplastic disorders. Treatment for cerebellar degeneration varies depending on the underlying cause.
What are the major diseases of the cerebellum?
Neurological diseases that feature cerebellar degeneration include:ischemic or hemorrhagic stroke, when there is lack of blood flow or oxygen to the cerebellumcerebellar cortical atrophy, multisystem atrophy, and olivopontocerebellar degeneration, progressive degenerative disorders in which cerebellar degeneration is a …
What are the symptoms of a damaged cerebellum?
Eye movement problems (nystagmus) With this side effect, the eye usually makes rapid, uncontrolled movements, which may cause your field of vision to appear scattered. This condition is known as nystagmus, and it occurs because the brain can no longer coordinate eye movement.
How is cerebellar atrophy treated?
There is no cure for hereditary forms of cerebellar degeneration. Treatment is usually supportive and is based on the person’s symptoms. For example, drugs may be prescribed to ease gait abnormalities. Physical therapy can strengthen muscles.
What are cerebellar disorders?
Cerebellar dysfunction causes balance problems and gait disorders along with difficulties in coordination resulting in ataxia, uncoordinated movements, imbalance, speech problems(dysarthria), visual problems (nystagmus) and vertigo as a part of the vestibulocerebellar system.
What are the anomalies of the cerebellar vermis?
Anomalies of the cerebellar vermis are diagnosed in this manner and include phenotypes consistent with Dandy–Walker malformation, rhombencephalosynapsis, displaying no vermis with fusion of the cerebellar hemispheres, pontocerebellar hypoplasia, or stunted growth of the cerebellum, and neoplasms.
Is the cerebellar vermis absent in Dandy Walker?
Dandy Walker malformation is characterized by enlarged posterior fossa and in which the cerebellar vermis is completely absent, or present in a rudimentary form, sometimes rotated accompanied by an elevation of the fourth ventricle. It is also commonly associated with dysplasias of brainstem nuclei.
What might be the result if a person’s cerebellum was damaged?
Cerebellum Damage. Damage to the cerebellum may result in difficulty with motor control. Individuals may have problems maintaining balance, tremors, lack of muscle tone, speech difficulties, lack of control over eye movement, difficulty in standing upright, and an inability to perform accurate movements.
How is the tentorium cerebelli separated from the cerebrum?
Tentorium cerebelli, an extension of the dura matter, separates the cerebellum from the cerebrum. It is composed of two hemispheres joined by the vermis and is sub-divided into three lobes – anterior, posterior, and flocculonodular, which are separated by two transverse fissures.
