The pattern and rate of progression of<unk>  depends on the disease involved.

When cortical<unk>  occurs in this brain area due to neurodegeneration, the first symptom is impairment in vision. A common vision impairment seen in patients with posterior cortical<unk>  is simultanagnosia, where a person is unable to see multiple locations at once or to quickly shift attention between these locations. When looking at images of a brain suffering from posterior cortical<unk> , one<unk> n see a loss in volume of the dorsal and ventral visual pathways, where visual stimuli is brought to the visual cortex and integrated information is sent back out to other areas of the brain. Because this disorder results in visual impairments, there is often a missed or delayed diagnosis, as the assumption is that there is a problem is in the eyes when the reality is that the problem is all the way in the back of the brain. * Prion diseases, a group of invariably fatal encephalopathies that<unk> use the progressive death of neurons. Infections Where an infectious agent or the inflammatory reaction to it destroys neurons and their axons, these include... * Encephalitis, acute inflammation in the brain * Neurosyphilis, an infection in the brain or spinal chord * AIDS, disease of the immune system Drug-induced * Alcohol (partially reversible): Standardized MRI evidence suggest chronic alcoholism (alcohol use disorder) is associated with widespread cortical<unk>  and major brain changes. In contrast to healthy controls, macrostructural findings indicate alcoholic brains are smaller in mass and volume. Neuroimaging studies also show that cortical shrinkage in “uncomplicated alcoholism” is most severe in the frontal lobe in comparison to the other divisions of the<unk>  cortex. In addition, neurological diseases that co-occur with excessive alcohol consumption—such as Wernicke-Korsakoff syndrome (WKS)—are characterized by substantial volume deficits of the diencephalon structures. In comparison to unaffected, non-alcoholic participants, tissue degeneration in WKS patients is found in specific white matter structures including the corpus<unk> llosum, the hippocampus, the subcortical basal ganglia (hypothalamus, thalamus, putamen), and the mammillary bodies. * Neuroleptic * Corticosteroid use (There appears to be correlations between degree of dosing with corticosteroids and<unk>
