Healthy aging is associated with numerous deficits in cognitive function, which have been attributed to changes within the prefrontal cortex (PFC). This chapter summarizes some of the most prominent cognitive changes associated with age-related alterations in the anatomy and physiology of the PFC.

Frontal lobe epilepsy is the second most common localization-related or focal epilepsy. Frontal lobe seizures are challenging to diagnose as the clinical manifestations are diverse due to the complexity and variability of the patterns of epileptic discharges, and the scalp electroencephalograph (EEG) can often be normal or misleading.

The cortex of the frontal lobes is 'motor' cortex in the broadest sense of the word. It is the peak of a hierarchy of anterior neural structures dedicated to the execution of actions. For the temporal organization of movements, the frontal cortex has at its disposal two cognitive functions that complement each other: memory and motor set, i.e.

An extremely rare case of lipomas on the cerebral surface in a 65-year-old female is reported. The tumors were located both in an unusual fissure of the right frontal convexity and under the right frontal lobe associated with and surrounded by areas of focal cortical dysplasia.

Gait abnormalities often result from disorders intrinsic to the cerebellum. Gait difficulties resulting from frontal lobe disease are less common but well recognized. The pathophysiologic mechanism of this type of ataxia is not well understood. One promising explanation implicates involvement of the frontopontocerebellar tract (Arnold's bundle).

Numerous theories discuss the neuropsychological functions of the frontal lobes, most based on some concept of supramodality, and an extensive literature presents the phenomenology and semiology of language and communication deficits after focal brain lesions involving the frontal lobes.

Despite the fact that clinical characteristics of frontal lobe seizures have been recently described better, differentiating seizures of frontal lobe origin from NES on clinical grounds alone is difficult. The difficulty has been compounded by the fact that both inter-ictal and ictal EEG can be normal or nonspecific, and the same is true of imaging ...

It appears that the human prefrontal regions have emerged over the years to distinguish themselves among the cerebral cortical structures as those most elusively resistant to neurocognitive analyses. Although a very substantial number of clinical observations based on human patients suffering from severe prefrontal injury have accumulated in the ...

The frontal lobe occupies the rostral portion of each hemisphere and has three surfaces: dorso-lateral, mesial, and orbital, which are bordered by the Rolando’s central fissure, the cingulate sulcus, and the insula sulcus, respectively. The prefrontal areas have reciprocal connections with the premotor cortex and, mediated by this area, with the motor ...

A report of severe akinetic episodes in patients with Parkinson disease (PD) has been the stimulus for the following discussion of akinesia and its variants. Severe persistent akinesia may occur in frontal lobe impairment. Therefore, it is likely that extension of the Parkinsonian dysfunction into the frontal lobe causes severe akinesia which should be
