- Can AIDS Have a Physical Impact on the Brain?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: A close friend of mine, diagnosed as having AIDS, has been acting
- progressively more bizarre. Is it just the emotional trauma of dealing with
- the disease, or can AIDS have a physical impact on the brain itself?
-
- ------------------------------------------------------------------------------
-
- ANSWER: Sadly, the brain is one of the most vulnerable organs to the AIDS
- virus. How the virus travels leaves the bloodstream and permeates the tissues
- of the brain itself is but one of the many riddles AIDS scientists are still
- working to unravel.
- The term AIDS dementia complex has been coined to describe the virus'
- impact on the brain. Early symptoms include forgetfulness, inability to
- concentrate, and slowness of thought, accompanied by physical symptoms such as
- loss of balance, leg weakness and deteriorating handwriting. The victim may
- also display signs of apathy, withdrawal, and depression.
- Often, the complex is diagnosed as an emotional reaction to the news of
- AIDS infection; in some patients, the dementia complex is the only symptom of
- the disease.
- Advanced signs of the disease include severe depression and advanced
- problems of body control, including incontinence, while brain scans often
- reveal atrophying of brain matter at this stage. In fact, autopsies reveal
- that the brain is almost always affected in AIDS cases.
- Experimental work with the drug zidovudine indicates it may have a
- beneficial effect on AIDS sufferers. While previous drug testing has focused
- on fighting the infectious complications associated with AIDS, the dementia
- complex may be a more accurate indicator of the degree to which the virus
- affects its victims.
- AIDS can attack the nervous system as a whole, and not just the brain.
- The spinal cord can be affected, and the virus has also been found in nerves
- in various areas of the body.
- The opportunistic nature of AIDS opens the door to a variety of
- conditions related to infections of the nervous system. A number of cases of
- neurosyphilis have been reported, suggesting that the risk of syphilis may be
- magnified when an AIDS virus is present. A reminder--if one was needed--of
- the hazards of promiscuity in the age of AIDS.
