mamillary bodies

Resection of the hamartoma from the mamillary bodies could play a role in memory loss as well.

Wernicke-Korsakoff syndrome in alcoholics particularly is associated with atrophy/infarction of specific regions of the brain, especially the mamillary bodies.

In Wernicke's this occurs specifically in the mamillary bodies, medial thalami, tectal plate, and periaqueductal areas.

The mechanism of this degeneration is unknown, but it supports current neurological theory that the mamillary bodies play a role in various "memory circuits" within the brain.

Frequently, secondary to thiamine deficiency and subsequent cytotoxic edema in Wernicke's encephalopathy, patients will have marked degeneration of the mamillary bodies.

The medial lemniscus carries axons from most of the body and synapses in the ventral posterolateral nucleus of the thalamus, at the level of the mamillary bodies.

The better known effect of the lesion of mamillary bodies, of the mamillothamic bundle and the fornix, if bilateral, is a particular (anterograde) amnesia (Korsakoff syndrom).

The mammillary bodies (mamillary bodies) are a pair of small round bodies, located on the undersurface of the brain, that, as part of the diencephalon form part of the limbic system.

Lobes occipital and temporal, the cortex and the connecting fibres of the corpus callosum; the limbic system - specifically the hippocampus and mamillary bodies that together with thefornix were indispensable to memory and recall.

It has been argued that the memory impairments can occur as a results of damage along any part of the mamillo-thalamic tract, which explains how WKS can develop in patients with damage exclusively to either the thalamus or the mamillary bodies.

Brain atrophy associated with WKS occurs in the following regions of the brain; the mamillary bodies, the thalamus, the periaqueductal grey, the walls of the 3rd ventricle, the floor of the 4th ventrical, the cerebellum, and the frontal lobe.

The amnesia that is associated with this syndrome is a result of the atrophy in the structures of the diencephalon (the thalamus, hypothalamus and mamillary bodies), and is similar to amnesia that is presented as a result of other cases of damage to the medial temporal lobe.
