Damage to the frontal lobe can cause increased irritability, which may include a change in mood and an inability to regulate behavior. [1] Particularly, an injury of the frontal lobe could lead to deficits in executive function , such as anticipation, goal selection, planning, initiation, sequencing, monitoring (detecting errors), and self ...
The causes of frontal lobe disorders can be closed head injury. An example of this can be from an accident, which can cause damage to the orbitofrontal cortex area of the brain. [2] Cerebrovascular disease may cause a stroke in the frontal lobe. Tumours such as meningiomas may present with a frontal lobe syndrome. [11]
This damage can be seen on neuroimaging scans. [5] Frontal lobe damage becomes the most prominent as alcoholics age and can lead to impaired neuropsychological performance in areas such as problem solving, good judgment, and goal-directed behaviors. [3] Impaired emotional processing results from damage to the limbic system.
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 in someone whose frontal lobe is damaged. [10] Consequences that are seen less frequently are also varied.
Phineas P. Gage (1823–1860) was an American railroad construction foreman remembered for his improbable: 19 survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his life—effects sufficiently ...
The frontal lobe is involved in decision-making, problem solving and impulse control, but the researchers say it's unclear whether the concussion-related changes actually affected those abilities.
Akinetic mutism can occur in the frontal region of the brain and occurs because of bilateral frontal lobe damage. Akinetic mutism as a result of frontal lobe damage is clinically characterized as hyperpathic. [5] It occurs in patients with bilateral circulatory disturbances in the supply area of the anterior cerebral artery. [2]
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans.
