Extractions: beta@sfaf.org by Mark Bowers HIV is known to affect most if not all systems in the body. A member of the subfamily of retroviruses that causes a variety of neurological and immunological diseases, HIV has been found in the brain as early as 2 days after initial infection. A type of dementia usually referred to as AIDS dementia complex (ADC), but also known as HIV-1-associated dementia or HIV-associated cognitive/motor complex, has been estimated to affect up to one-third of adults and one-half of all children with AIDS. It remains unclear exactly how and where HIV enters the brain. However, newly devised methods of measuring HIV in the cerebrospinal fluid (CSF) that bathes the spinal cord and the brain may be predictive of the risk of developing ADC and may help gauge efforts to prevent or treat it. The availability of antiretroviral drugs from 2 new classes, protease inhibitors and non-nucleoside reverse transcriptase inhibitors (NNRTI), potentially increases the number of options for preventing and treating ADC. New and better understanding of how HIV causes disease in the brain opens the door for testing novel therapies, including anti-inflammatory drugs, antioxidants, cytokine regulators and calcium channel blockers.

Extractions: Mark Katz, MD, and reported by Jim Stoecker The incidence of AIDS Dementia Complex is something less than 10%. Nonetheless, a majority of people with late stage AIDS will manifest some symptoms. AIDS Dementia Complex was first described in 1986 and was added to the CDC's list of AIDS-defining conditions. Only a small number receive an AIDS diagnosis because of dementia . In 1990, for instance, just 2.7% of AIDS cases were defined because of AIDS Dementia. Early symptoms of AIDS Dementia can be confused with general manifestations of clinical depression. These include apathy, loss of interest in one's surroundings and the like. Later symptoms involve cognitive and motor problems. Memory loss, as well as mobility problems, come into the picture. Diagnosing AIDS Dementia Complex is difficult. CAT scans are usually used, though these could be normal. Neuropsychiatric testing is required. Various other scans may also be called for. Treatment is usually individualized; there is no one accepted way to treat all cases. AZT in high doses is usually used, although the drug appears to help more with motor problems and less with cognitive problems. Other drugs to reduce brain inflammation may also be tried. Finally, there is symptomatic treatment; drugs are used to treat the specific symptoms of the individual.

Extractions: (advertisement) Synonyms, Key Words, and Related Terms: Background: Physicians frequently encounter neurologic and psychiatric complications in patients with human immunodeficiency virus (HIV) infection. HIV dementia is a common source of morbidity, usually observed in late stages of HIV disease. In 1986, this disorder was termed AIDS dementia complex (ADC) to describe a unique constellation of neurobehavioral findings. ADC now is considered a single entity with a broad and varied spectrum of clinical presentations and severity. Pathophysiology: Pathological changes predominantly are subcortical, involving the deep gray (ie, basal ganglia, thalamus) and white matter regions; it is a syndrome that specialists term subcortical dementia. The primary mechanism of neuronal dysfunction is the infiltration of infected macrophages or microglial cells into the brain, which then elaborate proinflammatory diffusable cellular neurotoxins, including tumor necrosis factor-alpha (TNF-alpha), cytokines, and interleukins. HIV does not directly infect the neuron itself, but the neuron is damaged by the effect of various proinflammatory neurotoxins. Using immunohistochemical techniques, researchers identified the HIV gp41 antigen abundantly in the brains of patients with HIV dementia. The results of these studies still are unclear about whether the HIV gp41 antigen is the only pathogenic mechanism. Other viral products are implicated in HIV dementia. A surface protein of HIV, gp120 causes neuronal death in vitro and is accompanied by the opening of calcium channels in the neuronal membrane. The basal ganglia show the highest immunostaining by the HIV p-24 antigen. Some studies show that gp41 expression in the basal ganglia and frontal lobes correlates significantly with the severity of dementia.
Extractions: The frequency of ADC increases with advancing HIV disease and as CD4+ cell counts decrease. It is fairly uncommon in people with early HIV disease, but it's more common in people with severely weakened immune systems and symptoms of advanced disease. Severe ADC is almost exclusively seen only in people with advanced HIV disease. ADC consists of many conditions that can be of varying degrees and may progressively worsen. These conditions can easily be mistaken for symptoms of other common HIV-associated problems including depression, drug side effects or opportunistic infections that affect the brain like toxoplasmosis or lymphoma. Symptoms of ADC may include poor concentration, forgetfulness, loss of short- or long-term memory, social withdrawal, slowed thinking, short attention span, irritability, apathy (lack of caring or concern for oneself or others), weakness, poor coordination, impaired judgment, problems with vision and personality change. Because ADC varies so much from person to person, it is poorly understood and has been reported and described in many conflicting ways. This publication will shed light on some of these issues as well as the available treatments for ADC.

DEPT PROGRAMS The Neurologic AIDS Research Consortium (NARC) is supported by the National Institutes of Health to design and carry out clinical trials to improve the therapy for HIV induced neurologic disease, and neurologic conditions associated with the AIDS virus. This consortium was established in 1993 when the NARC grant submitted by David B. Clifford, M.D . of Washington University School of Medicine was funded by the National Institute of Neurologic Disorders and Stroke (NINDS) to establish the consortium. Since that time the grant has supported studies of the natural history of neurologic performance in advanced AIDS, treatment of HIV associated peripheral neuropathy, progressive multifocal leukoencephalopathy, and cytomegalovirus. The NARC primarily sponsors studies in conjunction with the AIDS Clinical Trials Group (ACTG) . Studies currently available include treatment trials for AIDS dementia complex, peripheral neuropathy, and progressive multifocal

Conclusion Dementia is a brain disorder that affects a person's ability to think clearly and can impact his or her daily activities. AIDS dementia complex (ADC) dementia caused by HIV infection is a complicated syndrome made up of different nervous system and mental symptoms. These symptoms are somewhat common in people with HIV disease. The frequency of ADC increases with advancing HIV disease and as CD4+ cell counts decrease. It is fairly uncommon in people with early HIV disease, but it's more common in people with severely weakened immune systems and symptoms of advanced disease. Severe ADC is almost exclusively seen only in people with advanced HIV disease. ADC consists of many conditions that can be of varying degrees and may progressively worsen. These conditions can easily be mistaken for symptoms of other common HIV-associated problems including depression, drug side effects or opportunistic infections that affect the brain like toxoplasmosis or lymphoma. Symptoms of ADC may include poor concentration, forgetfulness, loss of short- or long-term memory, social withdrawal, slowed thinking, short attention span, irritability, apathy (lack of caring or concern for oneself or others), weakness, poor coordination, impaired judgment, problems with vision and personality change.

AIDS SA - AIDS Dementia Complex characteristics of the dementia associated with HIV infection was first describedby Navia in 1986 who coined the term aids dementia complex (ADC) . http://www.niv.ac.za/virussa/aidsa/v7_3.htm
Extractions: Management The neuropathological characteristics of the dementia associated with HIV infection was first described by Navia in 1986 who coined the term "AIDS dementia complex (ADC)" . The disease has also been referred to by the WHO as well as the American Academy of Neurology by the rather cumbersome and seldom used alternate term, "HIV-associated cognitive/motor complex" Initially, ADC was seen in 15 to 30% of HIV infected patients, virtually always in the advanced stage of AIDS, and usually accompanied by a profound immunosuppression as well as other signs of AIDS. In developed countries, the incidence of ADC has dropped dramatically because of the widespread use of zidovudine and it is now a rare disease in those patients who are on zidovudine treatment. ADC is a diffuse CNS disorder, charac-terized clinically as a subcortical dementia which manifests itself by slowness of mental function and by disturbances of cognitive and motor functions. The disease, if untreated, is progressive with patients ultimately reaching a vegetative state before death. The mortality rate for ADC is 3 times that of Pneumocystis pneumonia. Replication of HIV in the CNS plays a key role in the pathogenesis and therefore the disease is treatable by antiretroviral agents, especially zidovudine, which penetrates readily into the CNS, and much of the neurological damage is reversible. PATHOGENESIS The pathogenesis of ADC is marked by the following features:-

Extractions: AIDS Dementia Complex The most important CNS complication, that has been attributed to a primary effect of HIV, has been described using a variety of terms, including the AIDS dementia complex (ADC), subacute encephalitis and HIV encephalitis. The syndrome may represent more than one type of disease process. It is characterized by decreased concentration and rapidity of thought, loss of interest in activities, and slowness of motor movements. The link between HIV infection in the brain or in the body and this neurological condition still remains uncertain. While it is clear that patients severely affected by this disorder have HIV-infected macrophages within the brain, those with milder disease have not been shown to have active virus infection within the brain.

Extractions: Neurological Disorders Central nervous system (CNS) and peripheral nervous system (PNS) disorders in HIV-infected individuals may result from opportunistic infections, neoplasms and processes that appear to be primary effects of human immunodeficieny virus (HIV) itself. The nervous system may also be damaged as a result of the toxic effects of various treatments. Indeed, the majority of AIDS patients will eventually manifest one or more of these neurological conditions. Tozzi V et al.
