Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery. [1] Cardinal signs include vertigo, headache, vomiting, and ataxia. [2]
Rhombencephalosynapsis is an anomaly characterized by the absence or severe dysgenesis of the cerebellar vermis with fusion of the cerebellar hemispheres, peduncles, and dentate nuclei. Diagnostic features include fusion of the midbrain colliculi, hydrocephalus, absence of the corpus callosum other midline structural brain malformations. [21 ...
Cerebellar ataxia is a form of ataxia originating in the cerebellum. [1] Non-progressive congenital ataxia (NPCA) is a classical presentation of cerebral ataxias. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. [ 2 ]
Cerebellar cognitive affective syndrome (CCAS), also called Schmahmann's syndrome [1] is a condition that follows from lesions (damage) to the cerebellum of the brain. It refers to a constellation of deficits in the cognitive domains of executive function , spatial cognition , language , and affect resulting from damage to the cerebellum.
Truncal ataxia (or trunk ataxia) is a wide-based "drunken sailor" gait characterized by uncertain starts and stops, lateral deviations and unequal steps.It is an instability of the trunk and often seen during sitting. [2]
Midline shift is a shift of the brain past its center line. [1] The sign may be evident on neuroimaging such as CT scanning . [ 1 ] The sign is considered ominous because it is commonly associated with a distortion of the brain stem that can cause serious dysfunction evidenced by abnormal posturing and failure of the pupils to constrict in ...
There are two types of cerebellar disorders that produce dysmetria, specifically midline cerebellar syndromes and hemispheric cerebellar syndromes. Midline cerebellar syndromes can cause ocular dysmetria, a condition in which the eyes can not track an object properly and either overshoot (ahead of the object )or undershoot (lagging behind the ...
Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is an autosomal recessive late-onset heredodegenerative multisystem neurological disease. The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present.
