Image BV4515 (Color Enhanced Severe Alzheimer’s Disease)
This color enhanced and labelled coronal (frontal view) gross anatomic brain specimen demonstrates evidence of severe, endstage Alzheimer’s disease.
There is marked atrophy of the hippocampal formations (aqua) (which are very important for memory) with associated enlargement of the temporal horns (red) of the lateral ventricles. There is also prominent generalized atrophy of the remaining portions of the temporal lobes (yellow) with enlargement of the sylvian fissures.
Additionally, the image shows atrophy with enlargment of the third ventricle and bodies of the lateral ventricles. The lentiform nucleus of the basal ganglia is pink. The thalamus is dark blue with a small lacunar infarct in the left (on viewers right) thalamus. The caudate nuclei of the basal ganglia are purple.
