CT and MRI are most commonly used to observe the brain for cerebral atrophy. A CT scan takes cross sectional images of the brain using X-rays, while an MRI uses a magnetic field. With both measures, multiple images can be compared to see if there is a loss in brain volume over time. [20]
Little is understood about frontal lobe functions facilitating memory, but what is clear is that more in-depth research of brain injury patients is needed. Because most research compares those with brain injuries (whether frontal lobe or not) and those without, the scientific community is unsure whether certain memory impairment is specific to ...
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.
Damage to the limbic system involves loss or damage to memory, and may include: [citation needed] loss or confusion of long-term memory prior to focal neuropathy (retrograde amnesia) inability to form new memories (anterograde amnesia) loss of, or reduced emotions ; loss of olfactory functions; loss of decision-making ability
Approximately 10% of these silent strokes are silent lacunar infarctions. While dubbed "silent" due to the immediate lack of classic stroke symptoms, SLIs can cause damage to the surrounding brain tissue and can affect various aspects of a person's mood, personality, and cognitive functioning. A SLI or any type of silent stroke places an ...
Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries.

Ultra-detailed MRI scans reveal brain damage in severe COVID-19 The researchers used a relatively new scanning technology called ultra-high field (7T) quantitative susceptibility mapping.
Yellow softening is the third type of cerebral softening. As its name implies, the affected softened areas of the brain have a yellow appearance. This yellow appearance is due to atherosclerotic plaque build-up in interior brain arteries coupled with yellow lymph around the choroid plexus, which occurs in specific instances of brain trauma. [2]
