Definition
Organic brain syndrome (OBS) is a general term, referring to physical disorders (usually not psychiatric disorders) that cause decreased mental function.
Causes, incidence, and risk factors
OBS is a common diagnosis in the elderly. It is not an inevitable part of aging, however. OBS is not a separate disease, but is a general term used to categorize physical conditions that can cause mental changes.
Disorders associated with OBS include, but are not limited to:
Degenerative disorders:
Creutzfeldt-Jacob disease
Huntington disease
Multiple sclerosis
Normal pressure hydrocephalus
Pick disease
Senile dementia, Alzheimer type
Parkinson's disease
Diffuse Lewy Body disease
Cardiovascular disorders:
Arrhythmias -- may cause some types of OBS
Cardiac infections (endocarditis, myocarditis, etc.) -- may sometimes cause OBS
Hypertensive (related to high blood pressure) brain injury
Multi-infarct dementia (multiple strokes)
Stroke
TIA
Trauma-induced brain injury:
Chronic subdural hematoma (blood clot causing pressure on brain)
Concussion
Intracerebral hemorrhage
Subarachnoid hemorrhage
Dementia due to metabolic causes
Respiratory conditions -- may cause or aggravate OBS
Hypoxia (decreased oxygen in the body)
Hypercapnia (increased carbon dioxide levels in the body)
Infections
Any acute or chronic infection
Septicemia (presence in the bloodstream of toxic by-products caused by infection)
Meningitis
Encephalitis
Drug and alcohol related conditions
Intoxication, drug abuse, or alcohol use
Long-term effects of alcohol, Wernicke-Korsakoff syndrome
Alcohol withdrawal state
Withdrawal from drugs (especially sedative-hypnotics and corticosteroids)
Other medical disorders
Thyroid disease (high or low)
Vitamin deficiency (B12 and others)
Liver disease
Kidney disease
Cancer
Other conditions that may be related to organic brain syndrome include: depression, neuroses, and psychoses of various types, which may occur at the same time as the OBS.
Symptoms
Symptoms vary with the specific disease. In general, organic brain syndromes cause varying degrees of confusion, delirium (severe, short-term loss of brain function), agitation, and dementia (long-term, often progressive, loss of brain function).
Signs and tests
Testing and physical examination vary, depending on the specific disorder. Head CT scan, head MRI, EEG, and blood tests, to evaluate for medical conditions, are done frequently.
Treatment
Treatment varies with the specific disorder. Many of the disorders have nonspecific treatments -- primarily supportive care to assist the person in areas where brain function is lost.
Medications may be needed to reduce aggressive behaviors typical of some of the conditions in this category.
Expectations (prognosis)
See the specific disorder. Some disorders are acute and treatable, but many are chronic or progressive.
Complications
Loss of ability to interact with others or function independently is common.
Calling your health care provider
Call your health care provider if:
Organic brain syndrome has been diagnosed and you are uncertain of the actual, specific diagnosis
You have symptoms which suggest this problem
You have been diagnosed with OBS and symptoms become worse

Organic brain disorders are the result of physical disease or injury to the brain such as accident, stroke, etc.

Your parents or guardian needs to contact the physcian who made this diagnosis. It needs clarified as to the severity of this disease. You won't get an answer here unless a doctor gets on. You can google this disease.

It means there is something wrong with your brain structure, (ex. stroke, in which a portion of your brain loses its blood supply and is not able to function well) ... Yes, it is not commonly seen in young persons... The symptoms differ according to the part of the brain that is affected.
