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 ...
Signs and symptoms. Frontotemporal dementia is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11][14] Men and women appear to be equally affected. [15] It is the most common early presenting dementia. [16]
The frontal lobe is the largest lobe of the brain and makes up about a third of the surface area of each hemisphere. [3] On the lateral surface of each hemisphere, the central sulcus separates the frontal lobe from the parietal lobe. The lateral sulcus separates the frontal lobe from the temporal lobe. The frontal lobe can be divided into a ...
Witzelsucht can occur in the context of frontotemporal dementia, a neurological disorder resulting from degeneration of the frontal lobes and/or anterior temporal lobes. There are a range of neuropsychiatric symptoms associated with frontal lobe dementia, including progressive declines in social conduct, insight, and personal and emotional ...
A lobotomy (from Greek λοβός (lobos) 'lobe' and τομή (tomē) 'cut, slice') or leucotomy is a discredited form of neurosurgical treatment for psychiatric disorder or neurological disorder (e.g. epilepsy, depression) that involves severing connections in the brain's prefrontal cortex. [1] The surgery causes most of the connections to and ...
Perseveration is a common feature of frontal lobe syndrome, as well as neurodegenerative diseases such as progressive supranuclear palsy, corticobasal syndrome and chronic acetogenin poisoning. [8] Perseveration may also refer to the obsessive and highly selective interests of individuals on the autism spectrum.
The frontal lobe has a significant function in attention regulation. Therefore, patients with frontal lobe epilepsy are often found to be co-morbid for another disease called attention-deficit hyperactivity disorder (ADHD), which has a higher prevalence in children. This adds to the various cognitive and behavioral challenges, that they already ...
It is implicated in numerous psychopathologies and mental disorders, as well as short-term and long-term changes in non-clinical executive control. Executive dysfunction is the mechanism underlying ADHD paralysis, [ 2 ] and in a broader context, it can encompass other cognitive difficulties like planning, organizing, initiating tasks and ...
