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 ...
Cerebral atrophy is a common feature of many of the diseases that affect the brain. [ 1 ] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them. Brain atrophy can be classified into two ...
An overlap between symptoms can occur as the disease progresses and spreads through the brain regions. [14] Structural MRI scans often reveal frontal lobe and/or anterior temporal lobe atrophy, but in early cases the scan may seem normal. Atrophy can be either bilateral or asymmetric. [13]
Leukoaraiosis is a particular abnormal change in appearance of white matter near the lateral ventricles. It is often seen in aged individuals, but sometimes in young adults. [1][2] On MRI, leukoaraiosis changes appear as white matter hyperintensities (WMHs) in T2 FLAIR images. [3][4] On CT scans, leukoaraiosis appears as hypodense ...
Mostly in the frontal cortex, these differences often stem from a smaller brain volume, and the decreased blood flow that results influences the hypofrontality. [9] It has not been determined if the reduction of the frontal cortex is the ultimate cause of the symptoms, or if the condition worsens as the symptoms develop.
An MRI image of a brain with an invasive, multilocular tumor in the left frontal lobe of the brain. The origins of frontal lobe seizures can be different deviations. [8] One of the major reasons for FLE is abnormal cognitive development or sometimes congenital abnormal brain development. [8] Other causes are tumors, head trauma, and genetics. [9]
Neurology. 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.
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] Damage to the frontal lobe can cause increased ...
