Two main frontal areas have been implicated in the dream process. The first involves the deep white matter of the frontal lobes (just above the eyes). The main systems at work here involve the mesolimbic and mesocortical dopaminergic pathways. There are connecting fibres that run between frontal and limbic structures.
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 mini-SEA evaluates the frontal lobes dysfunctions, in particular the rostral and dorsal median parts of the prefrontal cortex. [6] [7] The mini-SEA is a simple and fast test to use in clinical practice. [8] [9] and is also presented as a useful clinical tool to assess the sequela of a frontal ataque fulminante or following traumatic brain ...
BvFTD, which results from damage to the frontal lobes of the brain, mainly causes problems with behaviour and personality. PPA, when damage occurs to the temporal lobes on either side of the head ...
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]
Currently, the anti-saccade task is currently used as a relatively crude or basic assessment of frontal lobe function in patients with neurological or psychiatric disorders. The task has high sensitivity, meaning that it is good at detecting frontal lobe dysfunction.
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]
Frontal lobe signs usually involve the motor system and may include many special types of deficit, depending on which part of the frontal lobe is affected: [citation needed] unsteady gait (unsteadiness in walking) muscular rigidity, resistance to passive movements of the limbs
