HIV and Dementia
What is HIV-linked dementia?
HIV/AIDS affects many of the body's organ systems, including the brain and nervous system. Most people don't know that HIV actually makes its way to the brain early in the disease process. HIV encephalopathy is caused by HIV spreading in the brain and harming it. It is one cause of dementia in people who have HIV. The greater the spread of infection in the brain and the more damage that results, the worse the dementia symptoms become.
AIDS dementia is also called AIDS dementia complex or HIV-linked dementia. It is a serious result of HIV infection. It is most often seen in advanced stages of the disease.
What causes HIV-linked dementia?
When HIV spreads to the brain, it causes encephalopathy. This is a disease that affects how the brain works. It causes dementia. The greater the spread of infection in the brain and the greater the damage that results, the worse the dementia symptoms become. People with HIV may also become infected with other organisms, such as cytomegalovirus and toxoplasmosis. They can also develop cancer, such as lymphoma of the central nervous system. Each of these infections or health problems can cause a drop in mental function very much like that caused by HIV.
What are the symptoms of HIV-linked dementia?
These are symptoms seen with HIV-linked dementia:
- Memory loss
- Thinking problems
- Trouble concentrating or staying focused
- Trouble speaking clearly or accurately
- Lack of interest in activities you used to enjoy
- Slow loss of motor skills, or less coordination
These symptoms may look like other health problems. Always see your healthcare provider for a diagnosis.
How is HIV-linked dementia diagnosed?
Your healthcare provider will ask about your past health. You will also have a full nervous system and sensory exam. You may also need these tests:
- Mental status test. This is a brief and simple test of memory and some other common thinking skills. It is often part of a full nervous system exam.
- Neuropsychological testing
- Basic tests of physical abilities or movement
- MRI. This imaging test uses a combination of large magnets, radio waves, and a computer to make detailed images of organs and structures in the body.
- CT scan. This imaging test uses a combination of X-rays and computer technology to make images of any part of the body, such as the bones, muscles, fat, and organs. CT scans are more detailed than X-rays.
- Blood tests
- Spinal fluid test. During this procedure, a healthcare provider puts a hollow needle into the lower back (lumbar spine).
How is HIV-linked dementia treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.
Treatment often involves:
- Antiretroviral therapy. This treatment lowers the amount of HIV in the body. It also can help ease dementia symptoms.
- Substance or alcohol abuse counseling. People with HIV who abuse drugs or alcohol can have more severe dementia symptoms.
- Prescription medicines. Along with other medicines you take for AIDS symptoms, your healthcare provider may give you antidepressants, antipsychotics, or stimulants. Deciding on which one will depend on what may be causing your dementia.
- Lifestyle changes. Regular exercise and a structured routine will help control HIV-linked dementia. Writing lists can help you stay organized and remember important details. A neurologist may advise working with a special therapist who can help you learn to better manage daily life.
- Coping strategies. If dementia symptoms become severe, you may need help at home from a skilled caregiver.
What are possible complications of HIV-linked dementia?
The slow loss of mental clarity and physical coordination can seriously reduce quality of life and day to day function. Without treatment, HIV-linked dementia can be fatal.
What can I do to prevent HIV-linked dementia?
People who are taking antiretroviral therapy are less likely to get HIV-linked dementia. Experts think this may be because these medicines help control the virus and maintain the immune system. A milder form of thinking problems (cognitive impairment) may still occur. It's called HIV-associated neurocognitive disorder (HAND).
Living with HIV-linked dementia?
Based on your level of dementia, you may need different therapies. HIV-linked dementia may gradually get worse, especially if your HIV infection is not well controlled. You will need more care as the disease gets worse over time.
When should I call my healthcare provider?
If you, a family member, or friend notice changes in your ability to speak, focus, or concentrate, talk with your healthcare provider. These symptoms are common to other health problems, such as other infections, depression, and nutritional deficiencies. Also talk with your healthcare provider about unusual shifts in mood or emotions and changes in social behavior. Best results are achieved with early diagnosis and treatment.
