Following a frontal lobe injury, an individual's abilities to make good choices and recognize consequences are often impaired. Memory impairment is another common effect associated with frontal lobe injuries, but this effect is less documented and may or may not be the result of flawed testing. [3]
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.
Pediatric acquired brain injury (PABI) is the number one cause of death and disability for children and young adults in the United States." [ citation needed ] and affects mostly children ages (6-10) and adolescent ages (11-17) around the world.
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.
The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral ...
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 ...
changes in personality such as disinhibition, inappropriate jocularity, rage without provocation; or loss of initiative and concern, apathy, akinetic mutism, general retardation "frontal release" signs, i.e. reappearance of primitive reflexes such as the snout reflex, the grasp reflex, and the palmomental reflex; unilateral loss of smell (anosmia)
