The insula, a structure found between the temporal lobe and the frontal lobe, is related to olfactory, gustatory, visceral, and limbic function. The posterior insula is related to auditory sensation, bodily sensations, and skeletomotor function. It also plays an important role in the experience of pain and mediates emotions, including disgust, anger, fear, empathy, happiness, and sadness. A stroke in this part of the brain can present with the attenuation or loss of these abilities, and often presents as a mental disorder. Interestingly, smokers who have a stroke in the insula stop smoking immediately.
This essay is not about being "politically correct." What is "correct" changes with the winds and tides and individual.This is a call to stop the use of the term "mentally ill" or "mental illness" and find replacements!
The Epidemic of Mental Illness: Why
Research shows patients with chronic, severe mental illness have four to nine times the prevalence of the virus. Conversely, most patients with Hepatitis C infection present to medical clinics with active psychiatric and substance use disorders. A 2005 research paper by Marian Fireman at the Northwest Hepatitis C Resource Center found that screening Hepatitis C patients for mental problems revealed that 93 percent had a current or past history of at least one mental disorder. Seventy-three percent had two disorders. The most common disorders were depression (81 percent), posttraumatic stress disorder (62 percent), any substance use disorder (58 percent), and bipolar disorder (20 percent).
