brain damage

Injury to the brain that is caused by various conditions, such as head trauma, inadequate oxygen supply, infection, or intracranial hemorrhage, and that may be associated with a behavioral or functional abnormality.

brain′-dam′aged (-dăm′ĭjd) adj.

brain damage

A 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).

brain damage

in sport this is usually a result of direct trauma to the head. More common in sports such as boxing, horse riding and falls during those carried out at height. See also head injury.

Q. What damage does depression do to the brain and how can you treat it? How does it affect your chemical balance, your brain? Is it critical or will be critical later in life? I just read on Yahoo News that Clinical stress could increase risk of Alzheimer's later in life. Does age matter like during teen years? I had depression and begun running. I noticed that I have a hard time focusing and absorbing information. I forgot a lot of things. All my brain seems to focus on is emotions. Can I change that? The running has made me feel a lot better afterwards

A. This is actually a good question- but I couldn’t find any research concerning long term damage from depression. It sounds unreasonable though…because there is no deprivation of oxygen or anything essential in depression. But the brain is a biological system that is under constant change – so it may be that pattern of thought changed. About the Alzheimer's- I only saw articles about depression because of Alzheimer.
