Those patients with a mild traumatic brain injury with frontal lobe damage seem to be only slightly affected, if affected at all. Frontal lobe injuries have been shown to cause decreased ability in combining events that are temporally separated (separated by time), as well as recalling information in its correct context.
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production. Frontal lobe syndrome can be caused by a range of conditions including ...
The most frequent cause of the syndrome is brain damage to the frontal lobe. Brain damage leading to the dysexecutive pattern of symptoms can result from physical trauma such as a blow to the head or a stroke [6] or other internal trauma. It is important to note that frontal lobe damage is not the only cause of the syndrome.
This personality change is characteristic of damage to the frontal lobe, and was exemplified in the case of Phineas Gage. The frontal lobe is the same part of the brain that is responsible for executive functions such as planning for the future, judgment, decision-making skills, attention span, and inhibition. These functions can decrease ...
Disinhibition is a common symptom following brain injury, or lesions, particularly to the frontal lobe and primarily to the orbitofrontal cortex. [4] The neuropsychiatric sequelae following brain injuries could include diffuse cognitive impairment, with more prominent deficits in the rate of information processing, attention, memory, cognitive flexibility, and problem-solving.
Behavioral and personality changes are also commonly observed due to changes of the brain structure in areas controlling hormones or major emotions. Headaches and pain can occur as a result of a brain injury, either directly from the damage or due to neurological conditions stemming from the injury.
Perhaps the first reported case of personality change after brain injury is that of Phineas Gage, who survived an accident in which a large iron rod was driven through his head, destroying one or both of his frontal lobes; numerous cases of personality change after brain injury have been reported since. [31] [33] [34] [43] [44] [48] [185] [186]
The most common reason for this profound change in personality is the traumatic brain injury. [6] Children whose brain areas have been injured or damaged, may present with attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder or OPD. [7] OPD is most often caused by lesions in three brain areas of frontal lobe: traumatic ...
