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 ...
Brain atrophy from vascular dementia: Specialty: Psychiatry, neurology Symptoms: Cognitive impairment, short-term memory loss [3] Complications: Heart disease, loss of ability to care for self and interact, pneumonia [4] Causes: Conditions that impair blood vessels in the brain and therefore interfere with oxygen delivery to the brain [3] Risk ...
Often shortened to MCI, this diagnosis is characterized by subtle yet noticeable changes in memory and cognitive ability, says Sarah McKay, PhD, a neuroscientist and author of The Women’s Brain ...
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 most severe brain atrophy appears to be associated with behavioral variant FTD, and corticobasal degeneration. [42] With regard to the genetic defects that have been found, repeat expansion in the C9orf72 gene is considered a major contribution to FTLD, although defects in the GRN and MAPT genes are also associated with it. [43]
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production.
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 ...
