Disconnection syndrome is another well-known side effect of the surgery. [14] This occurs due to the brain's inability to transfer information between the hemispheres. [ 15 ] One characteristic symptom is the "crossed-avoiding reaction", which is observed when one hemisphere does not respond to visual or sensory (e.g., touch, pressure, or pain ...
Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types of hemispherectomy. Functional hemispherectomy refers to when the diseased brain is simply disconnected so that it can no longer send signals to the rest of the brain and body.
It is light-sensitive and communicates visual messages to the brain. If the retina detaches, it moves and shifts from its normal position. This can cause photopsia, but can also cause permanent vision loss. Medical attention is needed to prevent vision loss. Procedures may include laser treatment, freezing, or surgery.
