Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.
Mild cognitive impairment (MCI) may be caused due to alteration in the brain triggered during early stages of Alzheimer's disease, to other causes, or to a combination of causes. [14] [15] Brain damage, brain injury, delirium and prolonged substance abuse can cause MCI. HIV-associated neurocognitive disorder can cause MCI. Risk factors of both ...

MRIs of affected individuals also show mild cerebellar and cerebral atrophy, or tissue breakdown, and gas cavity formation in the putamen. [8] Most importantly, the MRIs show misfolded ferritin proteins and iron deposits in the glial cells of the caudate, putamen, globus pallidus, cerebral cortex, thalamus, and purkinje cells , causing neuronal ...
Vascular dementia can be caused by ischemic or hemorrhagic infarcts affecting multiple brain areas, including the anterior cerebral artery territory, the parietal lobes, or the cingulate gyrus. [5] On rare occasion, infarcts in the hippocampus or thalamus are the cause of dementia. [ 12 ]
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
The external human LENAS brain shows findings in several major structures. There is mild atrophy of the frontoparietal regions of the brain and a mild reduction of the thalamus and rostral (front) part of the caudate nucleus (which is located in an area of the brain called the basal ganglia). [5]
