What is Archicerebellum syndrome?

Lesions of the flocculonodular lobe and adjoining parts of the caudal vermis (so‐called archicerebellar or flocculonodular syndrome) mainly due to tumors or hemorrhage cause postural ataxia of head and trunk during sitting, standing, and walking. Patients frequently fall while sitting.

What are some signs of cerebellar disease?

What are the symptoms of acute cerebellar ataxia?

impaired coordination in the torso or arms and legs.
frequent stumbling.
an unsteady gait.
uncontrolled or repetitive eye movements.
trouble eating and performing other fine motor tasks.
slurred speech.
vocal changes.
headaches.

Does ataxia affect bowel movements?

The eyes roll upwards and below or sideways rapidly of their own accord. This is called oscillopsia. Some ataxias also result in disturbance of bladder and bowel movements as well. There may be cognitive or memory loss accompanied by depression and/or anxiety.

Which is an archetypal sign of cerebellar dysfunction?

Ataxia is the archetypal sign of cerebellar dysfunction, but many other motor abnormalities may occur (see table Signs of Cerebellar Disorders ). Such malformations are almost always sporadic, often occurring as part of complex malformation syndromes (eg, Dandy-Walker malformation ) that affect other parts of the central nervous system (CNS).

Are there any neurologic disorders of the cerebellum?

Cerebellar Disorders. There is growing consensus that in addition to coordination, the cerebellum controls some aspects of memory, learning, and cognition. Ataxia is the archetypal sign of cerebellar dysfunction, but many other motor abnormalities may occur (see Table: Signs of Cerebellar Disorders ).

Which is a systemic disorder of the cerebellar system?

Systemic disorders include alcoholism (alcoholic cerebellar degeneration), thiamin deficiency, celiac disease, heatstroke, hypothyroidism, and vitamin E deficiency. Toxins that can cause cerebellar dysfunction include carbon monoxide, heavy metals, lithium, phenytoin, and certain solvents.

What kind of toxins can cause cerebellar dysfunction?

Toxins that can cause cerebellar dysfunction include carbon monoxide , heavy metals, lithium, phenytoin, and certain solvents. Toxic levels of certain drugs (eg, antiseizure drugs, sedatives in high doses) can cause cerebellar dysfunction and ataxia.
