    The person instead processes faces, bodies, objects, rooms, places, pictures in a bit-by-bit fashion. [17] When looking at a picture they can describe the parts of the picture but struggle to comprehend the picture as a whole. Simultagnosia occurs in Bálint syndrome [18] but may also occur in brain injury. This condition can also be described ...

  3. Visual agnosia - Wikipedia

    en.wikipedia.org/wiki/Visual_agnosia

    While cortical blindness results from lesions to primary visual cortex, visual agnosia is often due to damage to more anterior cortex such as the posterior occipital and/or temporal lobe(s) in the brain. [2] There are two types of visual agnosia, apperceptive and associative. Recognition of visual objects occurs at two levels. At an ...

    Phineas P. Gage (1823–1860) was an American railroad construction foreman remembered for his improbable: 19 survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his life‍—‌effects sufficiently ...

    The stroke caused aphasia — damage to parts of the brain responsible for language — which left Adelekun struggling for words. It was crushing for a woman who calls herself a “born talker ...

  6. Cerebral hypoxia - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hypoxia

    Even if the patient wakes up, brain damage is likely to be significant enough to prevent a return to normal functioning. [citation needed] Long-term comas can have a significant impact on a patient's family. [35] Families of coma patients often have idealized images of the outcome based on Hollywood movie depictions of coma. [36]

  7. Diffuse axonal injury - Wikipedia

    en.wikipedia.org/wiki/Diffuse_axonal_injury

    High levels of intracellular Ca 2+, the major cause of post-injury cell damage, [30] destroy mitochondria, [11] and trigger phospholipases and proteolytic enzymes that damage Na+ channels and degrade or alter the cytoskeleton and the axoplasm. [31] [26] Excess Ca 2+ can also lead to damage to the blood–brain barrier and swelling of the brain ...

  8. Right hemisphere brain damage - Wikipedia

    en.wikipedia.org/wiki/Right_hemisphere_brain_damage

    Right hemisphere brain damage (RHD) is the result of injury to the right cerebral hemisphere. [1] The right hemisphere of the brain coordinates tasks for functional communication, which include problem solving, memory, and reasoning. [1] Deficits caused by right hemisphere brain damage vary depending on the location of the damage. [2]

  9. Traumatic brain injury - Wikipedia

    en.wikipedia.org/wiki/Traumatic_brain_injury

    Diffuse injury manifests with little apparent damage in neuroimaging studies, but lesions can be seen with microscopy techniques post-mortem, [25] [26] and in the early 2000s, researchers discovered that diffusion tensor imaging (DTI), a way of processing MRI images that shows white matter tracts, was an effective tool for displaying the extent ...
