brain damage(redirected from Brain damaged)
Also found in: Dictionary, Thesaurus.
brain damageA term applied more often to the physically subtle, but functionally serious, injury sustained from temporary oxygen and sugar deprivation, than to gross and obvious injury from direct violence. Brain damage also commonly results from sudden local haemorrhage or THROMBOSIS, causing STROKE, and from toxic substances especially alcohol. Bacterial toxins released in the course of meningitis and brain abscess and inflammation caused by viruses are also damaging. Diseases such as multiple sclerosis can cause brain damage, as can the repeated multiple small haemorrhages sustained in boxing. Brain damage often affects the areas of higher function in a patchy way with loss of certain functions and retention of others. There may be paralysis and loss of sensation on one side of the body, epileptic fits, speech disturbances or loss of word comprehension (APHASIA), loss of certain learned voluntary skills (APRAXIA), or loss of part of the field of vision. Alternatively, brain damage may have a diffuse effect causing, in addition to focal effects, interference with conscious thought, memory and judgement. Loss of memory (amnesia) is a common feature. A proportion of brain-damaged people end up in a state of almost complete loss of the higher mental functions (AMENTIA).
