Goethe suggest that, ” Certain defects are necessary for the existence of individuality.” (1) Have you ever considered what was affecting a dangerous person’s brain? Studies show that scientist do not believe that every serial murderer was born to actually kill. Scientist have found abnormalities which reflect that few criminals have a lower Agenesis of the Corpus Callosum (ACC) inside of their brains. Agenesis of the Corpus Callosum is a remarkably rare uncommon congenital disorder. Others may say that Agenesis of the Corpus Callosum do not determine criminal behavior biologically because of their culture only define their illegal actions says Olivia Matthews. Some of the effects of the Agenesis of the Corpus Callosum are cognitive difficulties, psychosocial difficulties, and alexithymia are affected by this disorder.One of the common symptoms of Agenesis of the Corpus Callosum was cognitive difficulties. Schizophrenia is a disorder that a person ability is affected by thinking, feel, and clearly behaved. Cognitive difficulties are also one of Schizophrenia symptoms . It can affect your mindset and how you solve conflicts throughout your life. Several people may get the meaning of Cognitive confusing. Cognitive can cause depression or even have your stress level high. Patients with schizophrenia have mental health professionals that play a crucial role in increasing awareness uniting with family members about the risk of violent behaviors. Delusions of persecution are symptoms that are associated with violence. Usually, patients with this symptom is directed towards family members and takes place at home. Antisocial Personality Disorder (APD) is associated with serial killing and is considered the most broadly mental disorder. This disorder mood changes from anger, boredom and to general discontent. Sociopathic or psychopathic behavior problems are usually referred as harmful or dangerous. Environmental and genetic factors have been implicated, while the exact causes of this disorder are unknown. Considering the incidence of antisocial behavior is increasing in people with an antisocial biological parent the genetic factors are suspected. As a person who looks up to someone that has antisocial tendencies is more likely to develop them, however, environmental factors could also be hold responsible. One percent of women and about three percent of men have antisocial personality disorder. The prison population increased percentages that exist.Alexithymia expresses, describe or identify one’s feelings. Typically, people with Alexithymia display a lack of imaginative thought and have trouble balancing between emotions and bodily sensations. In 1976, alexithymia was first introduced as psychological construct. Study shows that approximately 8% of men and 2% of women experienced alexithymia, and that it includes moderate, mild, and severe intensities. Research also shows that alexithymia has two dimensions which is a cognitive and an affective dimension. Cognitive dimension is when a adult or child have a difficult time identifying, interpreting, and verbalizing their feelings (the “thinking” part of our emotional experience). The affective dimension is when struggling arise in expressing, feeling and imaging part of our emotional experience.Agenesis of the Corpus Callosum does determine criminal behavior biologically. Each of these symptoms has something to do with cognitive difficulties. I have explained the differences and similarities of cognitive difficulties, psychological difficulties, and alexithymia. I discussed a lot about behavioral problems, depression, and how difficult it is to identify one’s feelings. If you ever wondered what was actually going through a criminal mind think about Agenesis of the Corpus Callosum. The symptoms of this birth defect shows and explains almost everything. “There are crimes of passion and crimes of logic. The boundary between them is not clearly defined.” Albert Camus.
