Brain plasticity has helped explain the recovery process of brain damage induced retrograde amnesia, where neuro-structures use different neural pathways to avoid the damaged areas while still performing their tasks. [42] Thus, the brain can learn to be independent of the impaired hippocampus, but only to a certain extent. [13]
The famous case of HM, a man who had both his medial temporal lobes removed resulting in profound amnesia, illustrates how brain damage can tell us a lot about the inner workings of memory. One of the fundamental problems with studying human patients who have already acquired brain damage is the lack of experimental control. [1]
There are a variety of disabilities affecting cognitive ability.This is a broad concept encompassing various intellectual or cognitive deficits, including intellectual disability (formerly called mental retardation), deficits too mild to properly qualify as intellectual disability, various specific conditions (such as specific learning disability), and problems acquired later in life through ...
Take it easy with alcohol. Research finds that so-called "heavy" drinkers are more likely to develop dementia than "moderate" ones. But there's good news: Even dropping your drinking levels from ...
If reports are accurate, her injury will almost certainly need surgery, and it is often done within 1 to 2 days to address pain concerns and help patients get out of bed as quickly as possible to ...
People with damage to the left hemisphere of the brain are more likely to have anomic aphasia. Broca's area, the speech production center in the brain, was linked to being the source for speech execution problems, with the use of functional magnetic resonance imaging (fMRI), now commonly used to study anomic patients. [9]
In a mouse study, researchers found that zolpidem (Ambien), a common sleep aid, could prevent the brain from effectively clearing up 'waste', though it remains unclear whether this could affect ...
Radiation and chemotherapy can lead to brain tissue damage by disrupting or stopping blood flow to the affected areas of the brain. This damage can cause long term effects such as but not limited to; memory loss, confusion, and loss of cognitive function. The brain damage caused by radiation depends on where the brain tumor is located, the ...
