- Marked reduction in number of neurons following inj. of viral protein. Astrogliosis (also known as astrocytosis or referred to as reactive astrocytosis) is an abnormal increase in the number of astrocytes due to the destruction of nearby neurons from CNS trauma, infection, ischemia, stroke, autoimmune responses, and neurodegenerative disease. In healthy neural tissue, astrocytes play critical roles in energy provision, regulation of blood flow, homeostasis of extracellular fluid, homeostasis of ions and transmitters, and regulation of synapse function, and synaptic remodeling
- Subcortical dementia HIV dementia symptoms are more associated with motor slowing and loss of executive control than with language and memory disturbance. Motor symptoms are also often subtle in early stages, including occasional stumbling while walking or running, slowing of fine repetitive movements, such as playing the piano or typing, and slight tremor. On examination, patients will demonstrate impaired saccadic eye movements, dysdiadochokinesia, hyperreflexia, and, especially in later cases, frontal release signs (grasp, root, snout, and glabellar reflexes). In late stages, motor symptoms may be quite severe, with marked difficulty in smooth limb movements, especially in the lower extremities. Impairments on tests of psychomotor speed in patients at the time of AIDS diagnosis with no memory complaints have been shown to predict the development of HIV-associated dementia up to 2 years prior.

- The Department of Health and Human Services (DHHS) Panel on Antiretroviral Guidelines for Adults and Adolescents (the Panel) is a working group of the Office of AIDS Research Advisory Council (OARAC). The primary goal of the Panel is to provide recommendations for HIV care practitioners based on current knowledge of antiretroviral drugs used to treat adults and adolescents with HIV infection in the United States. Recommendations in these guidelines are based upon scientific evidence and expert opinion. Each recommended statement is rated with a letter of A, B, or C that represents the strength of the recommendation and with a numeral I, II, or III that represents the quality of the evidence. Henry J. Kaiser Family Foundation. ---Kaiser is a non-profit organization focusing on national health issues, as well as the U.S. role in global health policy. Unlike grant-making foundations, Kaiser develops and runs its own policy analysis, journalism and communications programs, sometimes in partnership with major news organizations.
- For each question, patients can answer: a) never, b) hardly ever, or c) yes, definitely. Patients are considered to have an “abnormal” result when answering “yes, definitely” on at least one question.

- A behavior contract is an agreement between a student, their parent and the teacher. It spells out the expected behavior, the unacceptable behavior, the benefits (or rewards) for improving behavior and the consequence for failing to improve behavior. This contract should be worked out with the parent and the child and is most effective if the parent reinforces the appropriate behavior, rather than the teacher. Accountability is an important part of the success of a behavior contract.
- Self-deprecation is the act of reprimanding oneself by belittling, undervaluing, or disparaging oneself,[1] or being excessively modest.[2][3] It can be used in humor and tension release. Self-deprecating and self-depreciating both mean self-belittling. Some commentators think that self-depreciating is the more apt term for this activity, but self-deprecating has far more currency in Canadian English. Either word is acceptable." To depreciate is (1) to lessen in value, or (2) to lower the value of something, especially by falsely undervaluing, disparaging, or belittling it. The word is most common in financial contexts. Deprecate traditionally means to express disapproval of, but over the last century it has gained another sense—to disparage or belittle—that makes it roughly synonymous with depreciate in that word’s second sense. The newer sense of deprecate is what’s meant in the common phrasal adjective self-deprecating, which means undervaluing oneself. Self-depreciating would carry roughly the same meaning, but it is likely to be considered a misspelling because self-deprecating is by far the more common form.
