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.
It is thought that it may be caused by the body's inflammatory response to surgery, stress hormone release during surgery, ischemia, or hypoxaemia. [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 ...

Vagus nerve stimulation can also increase the release of important brain chemicals such as serotonin and norepinephrine, which help regulate mood and are typically low in people with depression ...
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 ...

Neuropsychiatry is a branch of medicine that deals with psychiatry as it relates to neurology, in an effort to understand and attribute behavior to the interaction of neurobiology and social psychology factors.

Lower brain oxygen levels caused by sleep apnea were linked to changes to the white matter, which could lead to cognitive problem, a new study suggests. Sleep apnea impacts brain in ways that may ...
