Brain dysfunction in criminal behavior

Frontal lobe damage personality changes

These recent technological innovations are computerized tomography CT and magnetic resonance imaging MRI , which provide information on brain structure, and positron emission tomography PET and regional cerebral blood flow RCBF , which provide information on brain functioning. But many, many more people suffering frontal lobe injury have never committed an offence in their lives. Additional topics. Frontal lobe damage may also be attributed to birth or delivery complications, for example. It should be noted that these brain abnormalities may be caused by genetic, biological, or environmental agents. December 24, Brain Lesions May Play Role In Criminal Behavior Lesions to brain areas in people exhibiting criminal behavior all fall within a particular brain network involved in moral decision-making, new research suggests. Should he or she be punished in the same way as people without a lesion?

Brain dysfunction in criminal behavior

So the bottom line here is that we have more and more evidence which suggests that links between the brain and crime do exist. Is criminal behavior different than other symptoms suffered by patients after a brain lesion such as paralysis or speech trouble? Taken together, these studies suggest that frontal and temporal dysfunction may be associated with violent behavior. It is important to note, however, that not all individuals with brain lesions within the network identified in the study will commit crimes. To our knowledge, no study has been conducted examining pre-morbid measures of brain structure and function among criminals. Other Factors Also Contribute The findings were supported in tests of a separate group of 23 cases where the timing between brain lesions and criminal behavior was implied but not definitive. The network is not involved with cognition control or empathy. Frontotemporal Dementia Behavior Interest in a potential link between brain lesions and criminality became especially intense following the Texas Tower mass shooting carried out by Charles Whitman, who complained of headaches and personality changes prior to his killing 16 people and wounding 31 others. Additional topics. This is supported by studies such as that by Damasio and Damasio which showed that individuals with damage to the ventromedial frontal cortex developed abnormal social conduct. This is ultimately a question society must answer. Baer, Jr.

Many studies have shown, for example, that injury to the frontal lobes of the brain may be related to criminal behaviour. Lesions from 17 patients with acquired criminal behavior, manually traced onto a common brain atlas.

He was found to have a tumor in his brain, prompting the question of whether the brain injury contributed to his behavior. Lead author Richard Darby, MD, formerly of BIDMC and now assistant professor of neurology at Vanderbilt University and director of the frontotemporal dementia clinic at Vanderbilt, noted that he personally became interested in how neurological diseases might result in criminal behavior after caring for patients with frontotemporal dementiawho often commit nonviolent crimes as a result of their dementia.
