1. antly in lower extremity was common motor deficit in patients with mesial frontal motor cortices
2. Frontal lobe syndrome, in general, refers to a clinical syndrome resulting from damage, and impaired function of the prefrontal cortex, which is a large association area of the frontal lobe. The areas involved may include the anterior cingulate, the lateral prefrontal cortex, the orbitofrontal cortex, and the frontal poles
3. The frontal pole (FP) is a distinct subregion. Like the posterior frontal lobe (FL) boundary, volumes of some or all FL regions depend on the FP boundary(14). Ignoring this region may result in excess image noise from distributing the frontal lobes' anterior portion between multiple regions
4. Frontal lobe syndrome is a condition caused by damage of the frontal lobe. It is characterized by symptoms of personality and behavior deterioration in a previously normal person (also read about Kluver-Bucy syndrome). Frontal lobe anatomy and physiology Frontal lobe is the largest lobe of the brain

In the broader spectrum of corticobasal syndrome, patients often present with slowly progressive symptoms and signs including 1,2: apraxia; dystonia; postural instability; akinetic-rigid syndrome; myoclonic jerks; cognitive impairment, often with pronounced frontal lobe signs FRONTAL LOBE SYNDROME Frontal lobe Syndrome is an impairment of the frontal lobe that occurs due to damage, lesions, injury, tumour, disease etc in the frontal lobe. Frontal lobe lesion or damage results in impairment in a person's ability to make different types of functions: Disturbances of motor function Loss of fine movement Traditional classification systems divide the frontal lobes into the precentral cortex (the strip immediately anterior to the central or Sylvian fissure) and prefrontal cortex (extending from the frontal poles to the precentral cortex and includes the frontal operculum), which is broken into: orbitofrontal cortex (including the orbitobasal or ventromedial and the inferior mesial regions), ventrolateral prefrontal cortex, dorsolateral prefrontal cortex, medial prefrontal cortex (containing. Cortical and subcortical white matter involvement most frequently affects the occipital and parietal regions (98%), followed by the frontal lobe (68%), inferior temporal region (40%), and cerebellum (32%) ( Fig. 3.3 ). Involvement of the deep white matter, basal ganglia, thalami, brainstem, and splenium is less common but occurs in approximately 10% to 20% of cases Radiology department of the Alrijne Hospital in Leiderdorp, the Netherlands. The ACA supplies the medial part of the frontal and the parietal lobe and the anterior portion of the corpus callosum, basal ganglia and internal capsule.

4. Usually refers to any cause of recurrent or persistent atelectasis of the right middle lobe; Occurs at all ages but most common at two peaks: in children and over 50. Reportedly more common in women than men; Originally thought to be due only to bronchial obstruction, but it is more often present with non-obstructive lesion
5. Abstract. This article summarizes the current theories regarding the locations and functions of the three primary frontal lobe circuits. It forms the framework for structuring functional magnetic resonance imaging investigations. It can be used to assist in ( a ) detecting subtle lesions of the frontal circuits and ( b ) applying the current.
6. Frontal lobe syndrome. Frontal lobe syndrome is a broad term used to describe the damage of higher functioning processes of the brain such as motivation, planning, social behavior, and language/speech production 1).Although the cause may range from trauma to neurodegenerative disease, regardless of the cause, frontal lobe syndrome poses a difficult and complicated condition for physicians
7. Dorsolateral Frontal Lobe Injury Function: Monitors and adjusts behavior using 'working memory', executive function, planning, strategy formation Dysfunction: Lack of ability to plan or to sequence actions or tasks, poor working memory for verbal or spatial information (depending on left versus right cortex), disinterest, decreased attention to stimuli, lack abstract thinking and flexibility in thought, apathy

Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe that occurs due to disease or frontal lobe injury. The frontal lobe of the brain 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 head trauma, tumours, neurodegenerative diseases, neurosurgery and cerebrovascular disease. Frontal lobe impairment can be detected by recognition o Frontal lobe functioning is often used interchangeably with executive functioning, but this conflation of terms leads to both a muddying of definitions and furthers the misconception that the frontal lobe is an independent, uniform functional unit with a single set of functions. Frontal syndrome as a consequence of lesions in the. Several descriptions of Gerstmann's syndrome have been reported in associated with a lesion to the left frontal lobe, but none of these reports fulfilled the full tetrad of diagnostic criteria Answer. Traditional classification systems divide the frontal lobes into the precentral cortex (the strip immediately anterior to the central or Sylvian fissure) and prefrontal cortex (extending.

Dysexecutive syndrome refers to a range or cluster of cognitive, behavioural and emotional outcomes, which frequently occur together following a brain injury.. The term 'dysexecutive syndrome' is preferred over 'frontal lobe syndrome' because it emphasises the functional.
5. The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere. It is parted from the parietal lobe by a groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral sulcus. The most anterior rounded part of the frontal lobe is known as the frontal pole, one of the three poles of the cerebrum. The frontal lobe is covered by the frontal cortex. The frontal cortex include

The frontal lobe includes the motor cortex (areas 4, 6, 8, 44), the prefrontal cortex (areas 9-12 and 45-47), and the cingulate gyrus (p. 144). It is responsible for the planning, monitoring, and performance of motor, cognitive, and emotional functions (executive functions). Frontal lobe syndromes may be due to either cortical or subcortical damage and thus cannot be reliably localized without. Catherine A. Mateer, Claire S. Sira, in Encyclopedia of the Neurological Sciences, 2003 Cognitive Symptoms Associated with Frontal Lobe Injury. Common cognitive effects of frontal lobe injury involve the so-called executive functions. Frontal or executive deficits all involve problems in goal-directed behavior in novel contexts, in which there may be competing but often erroneous response. The frontal lobe is a relatively large lobe of the brain, extending from the front of the brain almost halfway towards the back of the brain. Damage to the frontal lobe of the brain can cause a range of symptoms, including motor weakness and behavioral problems. A variety of conditions can damage the frontal lobe, including stroke, head trauma.

Mesial frontal lobe syndromes: correlations between neurological deficits and radiological localizations Tohoku J Exp Med. 1990 Aug;161 Suppl:231-9. Authors H Mochizuki 1 , H Saito. Affiliation 1 Department of Neurology, Tohoku University School of Medicine, Sendai. PMID: 2082501 Abstract. Frontal lobe syndrome is a broad term used to describe the damage of higher functioning processes of the brain such as motivation, planning, social behavior, and language/speech production. Although the etiology may range from trauma to neurodegenerative disease, regardless of the cause frontal lobe syndrome poses a difficult and complicated. Magnetic resonance imaging (MRI) for manual volumetric measurement of the brain's frontal lobe and its subregions is an established method for researching neural correlations of clinical disorders or cognitive functions (1).. However, there is no consensus on MRIs regarding the methods radiologists use to identify appropriate boundaries of a given region of interest (ROI)

Frontal lobe dysfunction is associated with blood alcohol level and occurs during acute intoxication with many recreational drugs. Sex. Traumatic brain injury is much more common in men than women both in the United States and worldwide. Gender predominance depends on the specific underlying neurologic disorder.
