[5] [6] Post-operative cognitive dysfunction can complicate a person's recovery from surgery, delay discharge from hospital, delay returning to work following surgery, and reduce a person's quality ...
After a few operations using ethanol, Moniz and Almeida Lima changed their technique and cut out small cores of brain tissue. They designed an instrument which they called a leucotome and called the operation a leucotomy (cutting of the white matter). [38] After twenty operations, they published an account of their work.

Therefore, special measures must be taken to protect the brain, such as a helmet or a temporary implant in the skull. [14] When the patient has healed sufficiently, the opening in the skull is usually closed with a ...
Disconnection syndrome is another well-known side effect of the surgery. [15] This occurs due to the brain's inability to transfer information between the hemispheres. [ 16 ] 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 ...
Not long after, the seizures started up again and the family was told that Caper would need a second surgery to remove more pieces of his brain. “The first surgery had a 60% chance of giving him ...
CT and MRI are most commonly used to observe the brain for cerebral atrophy. A CT scan takes cross sectional images of the brain using X-rays, while an MRI uses a magnetic field. With both measures, multiple images can be compared to see if there is a loss in brain volume over time. [20]
