focal lesion

The risk of identifying focal lesions on a large scale in any screening programme therefore seems negligible.

Gelastic seizures can be due to focal lesions to the hypothalamus.

This focal lesion can be fairly large.

Hematomas, also focal lesions, are collections of blood in or around the brain that can result from hemorrhage.

In contrast to the general impairment imposed for schizophrenics, focal lesions assumed specific deficits.

It also allows for characterization and biopsy of any focal lesions found in the upper gastrointestinal tract.

As already stated, small vessel disease and focal lesions often overlap, so these two patterns may be evident in the same individual concurrently.

Dissociated sensory loss always suggests a focal lesion within the spinal cord or brainstem.

Of great interest to researchers are individuals who experience MH with focal lesions and epileptic brain activity.

More recently, the ontogenetic emergence of language has been examined from a biological viewpoint, using data on language processing from children with early focal lesions.

One particular study used patients with focal lesions on the basal ganglia (specifically the putamen) due to stroke in order to study category learning.

It also has been proposed to use changes that are visible on neuroimaging, such as swelling, focal lesions, or diffuse injury as method of classification.

Vascular lesions can be the result of diffuse cerebrovascular disease, such as small vessel disease, or focal lesions; usually both.

Focal lesions such as neoplasms, tumors, hemorrhages, demyelination, or other damage may be causing dysfunction of the cerebellum and correspondingly the intention tremor.

The largest risks for PTS are having an altered level of consciousness for a protracted time after the injury, severe injuries with focal lesions, and fractures.

Since 1954 it has been known that focal lesions of the inferotemporal cortex produce a severe and abiding impairment in visual discrimination performance in monkeys (see Dean 1982).

The liver is the one organ in the abdomen in which MRI has been shown to be slightly better than computed tomography in the detection of focal lesions.

His studies have involved the correlation of focal lesions in the brain with subtle disorders of motor performance, previously undetected but now exposed and analysed in ingenious behavioural experiments.

In patients with obstructive jaundice secondary to extrahepatic bile duct obstruction, about one third have a focal lesion detected on initial ultrasound and about two thirds on computed tomography.

Despite this theoretical risk, the possibility of safely establishing a tissue diagnosis in about two thirds of patients with a focal lesion on imaging justifies percutaneous aspiration cytology as a first line investigation.

Adjunctive corticosteroids (e.g., dexamethasone) should be administered to patients with TE when clinically indicated only for treatment of a mass effect associated with focal lesions or associated edema (BIII).

Children with a focal lesion (a single point of brain abnormality causing the epilepsy) who would make suitable candidates for surgery are more likely to become seizure-free with surgery than with the ketogenic diet.

Contact phenomenon contribute to the development of focal lesions, e.g. frontal and temporal lesions due to contact with the sphenoid bone.18 Magnetic resonance imaging (MRI) studies have supported these theories.

They can detect, localize and quantify focal interruptions along the somatosensory pathways, which may be due to any number of focal neurological problems, including trauma, compression, multiple sclerosis, tumor or other focal lesions.

Much of what is understood about the functions of the cerebellum stems from careful documentation of the effects of focal lesions in human patients who have suffered from injury or disease or through animal lesion research.
