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 ...
An increase in impulsivity, risk taking or both is often seen in individuals following frontal lobe damage.The two related terms differ in that impulsivity is a response disinhibition, while risk taking is related to the reward-based aspects of decision-making. [7]
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.
Frontal lobe epilepsy (FLE) is a neurological disorder that is characterized by brief, recurring seizures arising in the frontal lobes of the brain, that often occur during sleep. [1] It is the second most common type of epilepsy after temporal lobe epilepsy (TLE), and is related to the temporal form in that both forms are characterized by ...
Other ways in which injury can occur include traumatic brain injuries incurred following accidents, diagnoses such as Alzheimer's disease or Parkinson's disease (which cause dementia symptoms), and frontal lobe epilepsy (which can occur at any age). [10] Very often, frontal lobe damage is recognized in those with prenatal alcohol exposure.
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]
Early cases of Witzelsucht observed damage to the mesial-orbital region of the frontal lobe. [6] In general, damage to this area results in puerility, disinhibition, and an inappropriate jocular affect. Subjects with damage to this part of the brain show a preference for gallows humor [citation needed]. The frontal lobes are also involved in ...
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.
