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]
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.
Confabulation is believed to be a result of damage to the right frontal lobe of the brain. [4] In particular, damage can be localized to the ventromedial frontal lobes and other structures fed by the anterior communicating artery (ACoA), including the basal forebrain, septum, fornix, cingulate gyrus, cingulum, anterior hypothalamus, and head of ...
Damage in the watershed region does not directly harm the areas of the brain involved in language production or comprehension; instead, the damage isolates these areas from the rest of the brain. [1] If there is damage to the frontal lobe, executive functions related to language use are often affected. Executive functions relevant to language ...
Only one case of gourmand syndrome has been reported in a child. He was born with issues with his right temporal lobe; at eight years old he began to experience seizures, within the year of the seizures beginning, his behavior began to change to the symptoms of gourmand syndrome. [2]
Anterior cerebral artery syndrome is a condition whereby the blood supply from the anterior cerebral artery (ACA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the medial aspects of the frontal and parietal lobes, basal ganglia, anterior fornix and anterior corpus callosum.
Only damage to the right hemisphere of the brain, not the left, is linked to humor. Specifically, pathology in the right frontal lobe (specifically the superior and anterior regions) correlated with deficits in humor in patients as opposed to other brain regions in the right hemisphere. [6]
