Cerebral disconnection syndrome

From Psy3242


Cerebral disconnection syndrome is a general term that groups a number of neurological disorders together that involve interruption of fibre pathways in the cerebrum. In other words the different types of neurological disorders are due to information being blocked or disrupted and not being properly processed. Such neurological disorders include aphasia, left-sided apraxia, split-brain, and tactile aphasia.


Aphasia is a disorder in which the person has difficulty speaking, not only saying words but putting together simple grammar. This disorder comes from damage to parietal lobe usually on the left hemisphere of the brain. Damage can com from not only accidental damage or trauma to the brain, but also stokes and tumors are able to bring the onset of aphasia. Today aphasia is separated into two different types; Broca and Wernicke’s aphasia. Broca’s aphasia is distinguished by damage being primarily in the frontal lobe of the brain. Those suffering with Broca’s aphasia have difficulty speaking in smooth and clear sentences and usually have great deal of trouble speaking for long periods of time. Most patients have trouble saying words such as “and”, “the”, and “is”. Usually these people know what they want to say, are aware that they are speaking unclearly and unable to control how they articulate their words. Wernicke’s aphasia is very different from Broca’s. Characterized by damage specifically to the temporal lobe of the brain, those suffering from this disorder are able to speak long sentences that usually make very little sense. These people may add words to their sentence that may be unnecessary or create new words. These people also usually are unable to understand things being said also, which is the reason why they are not able to catch the mistakes they make.


Similar to aphasia, apraxia is another speech disorder in which the person suffering from this disorder is unable to speaking clearly and with consistency. Apraxia can result from brain trauma, stroke, or tumor in the brain.
