The gene GPR56 is a member of the adhesion G protein-coupled receptor family and is directly related to causing Bilateral frontoparietal polymicrogyria, -6. Other genes in the G protein-coupled receptor family have effects with this condition as well such as the outer brain development, but not enough is known to carry out all the research ...
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] Registration of images at different points of time (e.g., one year apart) can show evidence of atrophy that otherwise at individual time points may be reported as ...
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
Bilateral frontoparietal polymicrogyria is a genetic disorder with autosomal recessive inheritance that causes a cortical malformation. Our brain has folds in the cortex to increase surface area called gyri and patients with polymicrogyria have an increase number of folds and smaller folds than usual. [ 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]
Animation. Parietal lobe (red) of left cerebral hemisphere. The parietal lobe is defined by three anatomical boundaries: The central sulcus separates the parietal lobe from the frontal lobe; the parieto-occipital sulcus separates the parietal and occipital lobes; the lateral sulcus (sylvian fissure) is the most lateral boundary, separating it from the temporal lobe; and the longitudinal ...
Frontotemporal lobar degeneration; Neuropathologic analysis of brain tissue from FTLD-TDP patients. Ubiquitin immunohistochemistry in cases of familial FTLD-TDP demonstrates staining of (a) neurites and neuronal cytoplasmic inclusions in the superficial cerebral neocortex, (b) neuronal cytoplasmic inclusions in hippocampal dentate granule cells, and (c) neuronal intranuclear inclusions in the ...
Focal means that it is limited to a focal zone in any lobe. [2] Focal cortical dysplasia is a common cause of intractable epilepsy in children and is a frequent cause of epilepsy in adults. There are three types of FCD with subtypes, including type 1a, 1b, 1c, 2a, 2b, 3a, 3b, 3c, and 3d, each with distinct histopathological features.
