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] Damage to the frontal lobe can cause increased irritability, which may include a change in mood and an inability to regulate behavior. [1]
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]
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 ...
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.
CT scans of patients with a tension pneumocephalus typically show air that compresses the frontal lobes of the brain, which results in a tented appearance of the brain in the skull known as the Mount Fuji sign. [1] [2] [3] The name is derived from the resemblance of the brain to Mount Fuji in Japan, a volcano known for its symmetrical cone.
A person with dissociated frontal and cerebellar regions may have difficulties with selecting a response to a stimuli, or difficulties with response initiation. [1] Fronto-cerebellar dissociation can often result in either the frontal lobe or the cerebellum becoming more active in place of the less active region as a compensatory effect. [2] [3]
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.
MRI is one of the best techniques that can detect the lesions in the brain of the FCMS that some of the times are missed by just using a Computer-Tomography Scan. Also, this type of imaging can reveal right frontal lobes contusions encompassing the anterior operculum, the premotor area, and the association area. [10]
