Which brain structure is associated with disconnection syndrome?

Split-brain syndrome, also called callosal disconnection syndrome, condition characterized by a cluster of neurological abnormalities arising from the partial or complete severing or lesioning of the corpus callosum, the bundle of nerves that connects the right and left hemispheres of the brain.

What is disconnection apraxia?

Diagonistic apraxia is a unique disconnection syndrome, in which a patient’s hands are uncoordinated, and the left hand has to be verbally instructed to follow a patient’s will. Liepmann and Mass first reported the symptoms in 1907 (1).

What is callosal disconnection syndrome?

Callosal disconnection syndrome (CDS) is characterized by the impairment of interhemispheric transfer of information caused by an interruption of callosal commissural fibers. It has been also reported that the damage to the corpus callosum (CC) can cause acquired stuttering as well as CDS.

When does disconnection syndrome occur?

Disconnection syndromes usually reflect circumstances where regions A and B still have their functional specializations except in domains that depend on the interconnections between the two regions.

What happens if your corpus callosum is damaged?

Lesions of any part of the corpus callosum might lead to loss of contact between bilateral hemispheres that cause mental disorders, pseudobulbar palsy, speech and movement ataxia.

What is meant by disconnection?

What causes disconnection?

Disconnection syndrome is a general term for a collection of neurological symptoms caused — via lesions to associational or commissural nerve fibres — by damage to the white matter axons of communication pathways in the cerebrum (not to be confused with the cerebellum), independent of any lesions to the cortex.

Is there a classical Callosal disconnection syndrome?

A classical callosal disconnection syndrome was found in 2 out of all patients with corpus callosum infarctions. Statistical differences in the risk factor and infarct pattern between the genu and/or body group and splenium group were revealed.

Can a corpus callosum injury affect the right hand?

One of the strangest symptoms of corpus callosum damage is a condition known as alien hand syndrome. While it most commonly affects the left hand, it can affect the right in some cases.

What are the symptoms of corpus callosum infarction?

Corpus callosum infarction patients suffered from a broad spectrum of symptoms including weakness and/or numbness of the limbs, clumsy speech, and vertigo, which could not be explained by lesions in corpus callosum.

Which is an example of commissural disconnection syndrome?

An example is commissural disconnect in adults which usually results from surgical intervention, tumor, or interruption of the blood supply to the corpus callosum or the immediately adjacent structures. Callosal disconnection syndrome is characterized by left ideomotor apraxia and left-hand agraphia and/or tactile anomia, and is relatively rare.
