1 de jun. de 2004 · The frontal lobes appear necessary for the highest levels of conscious processing, with the right frontal lobe being particularly important. The hierarchy is set up such that higher levels use the modelling capabilities of lower levels, allowing top–down control of lower levels of processing according to the needs of the modelling at higher levels.
26 de oct. de 2020 · Another study also demonstrated the reduced gray matter volume in the frontal, temporal, parietal, and occipital lobes of schizophrenic patients. However, earlier onset of psychosis, especially in schizophrenic patients, is associated with the most premature disease-related disruption of anatomical brain growth [ 36 ].

Strokes involving the orbital cortex can be associated with personality changes, impulsivity, poor social judgment, reduced empathy, altered self-regulation, lack of goal-directed behavior, and environmental dependency. Some strokes may occur primarily in the subcortical white matter within the frontal lobes.
Abstract. Provides a review of anatomical, imaging, and neurochemical studies in schizophrenia, provides evidence for frontal lobe impairment in schizophrenia, and discusses the relation between frontal lobe and medial temporal lobe abnormalities in this disorder. The authors expand on their theory of how dopaminergic hypofrontality can lead to ...
7 de jun. de 2021 · Neuropsychiatric symptoms (NPSs) are common in patients with Alzheimer’s disease (AD) and are associated with accelerated cognitive impairment and earlier deaths. This review aims to explore the neural pathogenesis of NPSs in AD and its association with the progression of AD. We first provide a literature overview on the onset times of NPSs. Different NPSs occur in different disease stages ...
2 de oct. de 2019 · All other frontal lobe volumes showed statistically significant differences among the three groups . The comparison of brain volumes between different diagnostic groups is shown in Figure 2. Compared to MCI, the bvFTD group showed extensive atrophy in frontal cortex, striatum and temporal lobes, and also enlarged lateral ventricles.
