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 ...
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]
Frontal lobe damage often disrupts this process, preventing the retrieval of information and the evaluation of its output. [ 21 ] [ 22 ] Furthermore, researchers argue that confabulation is a disorder resulting from failed "reality monitoring/source monitoring" (i.e. deciding whether a memory is based on an actual event or whether it is ...
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.
Bruns apraxia, or frontal ataxia, is a gait apraxia [1] found in patients with bilateral frontal lobe disorders.It is characterised by an inability to initiate the process of walking, despite the power and coordination of the legs being normal when tested in the seated or lying position.
In most cases of executive dysfunction, deficits are attributed to either frontal lobe damage or dysfunction, or to disruption in fronto-subcortical connectivity. [1] Neuroimaging with PET and fMRI has confirmed the relationship between executive function and functional frontal pathology. [ 1 ]
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 frontal lobe is responsible for problem solving, motor function, memory, judgment, impulse control, and social behavior. It is also needed for goal-directed behavior. Patients with frontal lobe injury may have problems in the selection, production, and organization of goal-directed behavior. [5]
