DAT (computer science) digital audio tape DAT (1)Digital Audio Tape.DAT (2)Dynamic Address Translation.DAT(1) (DATa) See DAT file.
(2) (Dynamic Address Translator) A hardware circuit that converts a virtual memory address into a real address.
(3) (Digital Audio Tape) An earlier magnetic tape technology from Sony that was used for audio recording and data backup. Introduced in 1987, DAT used 4mm cartridges that looked like thick audio cassettes. DAT was initially a CD-quality audio format that was expected to replace analog audiotapes for consumers but wound up being used by professional musicians and sound studios. In 1988, Sony and HP defined the Digital Data Storage (DDS) format for DAT as a computer storage medium. Like videotapes, DAT used helical scan recording. In 2005, Sony ceased production of DAT drives. See magnetic tape and ADAT.

The antibodies present in the blood do not, themselves, cause agglutination. It is the addition of an antibody made in animals (antiglobulin) that stimulates red blood cell clumping. The direct antiglobulin test (DAT) is used to diagnose autoimmune hemolytic anemia and hemolytic disease of the newborn. The indirect antiglobulin test (IAT), or Coombs' test, is used to identify blood types. Synonym: Coombs' testdirect antiglobulin test Abbreviation: DAT
A laboratory test for the presence of complement or an antibody that is bound to a patient's red blood cells (RBCs). The test is used in patients with autoimmune hemolytic anemia, hemolytic disease of the newborn, and transfusion reactions. After the patient's RBCs are washed to remove unbound antibodies, they are mixed with antihuman globulin serum containing polyvalent antibodies that bind with the antibody or complement on the RBCs and cause them to agglutinate (clump). Monoclonal antibodies can be used to identify the specific class of antibody or complement component causing RBC destruction. See: Coombs' test

dementia (di-men'cha) [L. dementia, madness] A progressive, irreversible decline in mental function, marked by memory impairment and, often, deficits in reasoning, judgment, abstract thought, registration, comprehension, learning, task execution, and use of language. The cognitive impairments diminish a person's social, occupational, and intellectual abilities. In the U.S., 4.5 million people are afflicted by dementia. The prevalence is esp. high in the very elderly: about 20% to 40% of those over 85 are demented. Dementia is somewhat more common in women than in men. It must be distinguished by careful clinical examination from delirium, psychosis, depression, and the effects of medications. See: Alzheimer disease; Huntington chorea; Parkinson disease; table SymptomsThe onset of primary dementia may be slow, taking months or years. Memory deficits, impaired abstract thinking, poor judgment, and clouding of consciousness and orientation are not present until the terminal stages; depression, agitation, sleeplessness, and paranoid ideation may be present. Patients become dependent for activities of daily living and typically die from complications of immobility in the terminal stage. EtiologyDementia may result from many illnesses, including AIDS, chronic alcoholism, Alzheimer disease, vitamin B12 deficiency, carbon monoxide poisoning, cerebral anoxia, hypothyroidism, subdural hematoma, or multiple brain infarcts (vascular dementia). TreatmentSome medications, e.g., donepezil, nemantidine, and tacrine, improve cognitive function in some patients. Patient careDemented patients deserve respectful and dignified care at all stages of their disease. Caregivers assist the demented with activities of daily living and with the cognitive and behavioral changes that accompany the disease. A variety of nursing interventions may reduce the risk of inadvertently precipitating behavioral symptoms. Health care professionals should reinforce the patient's abilities and successes rather than disabilities and failures. Caregivers can help the patient make optimal use of his or her abilities by reducing the adverse effects of other health conditions, sensory impairments, and cognitive defects while maximizing social and environmental factors that support functional capacity. Daily routines should be adjusted to focus on the person rather than the task, e.g., the comfort of bathing rather than the perceived need to bathe in a certain way at a certain time. Interaction and communication strategies should be adjusted to ensure that the message delivered is the one perceived (obtain attention, make eye contact, speak directly to the individual, match nonverbal communication and gestures to the message, slow the pace of speech, use declarative sentences, use nouns instead of pronouns). Commands including the word “don’t” and questions beginning with “why” should be avoided. Tasks should be broken down into manageable steps. Reassurance and encouragement are provided to assist the patient to act more independently. Reality grounding is not necessary for such a patient; thus, if the patient asks to see his mother (who is dead), reminding him of her death may reinforce the pain of that loss. It may be better to redirect the conversation, asking the patient to talk about his mother, instead. Written agreements and reminders may not be as useful as they would be in the care of other patients, for a demented patient may not remember what has been negotiated and agreed upon in the past. The patient’s environment should be adjusted to provide needed safety. Finding the correct balance between doing too much or too little may be difficult for the caregiver, who should recognize that the balance may shift day to day and that patience and flexibility are more helpful. Caregivers must be aware that the patient will have moments of lucidity, which should be treasured but not considered evidence that the patient is exaggerating or feigning his or her disease to obtain attention. Family members who provide care must be aware that they, too, have emotional needs and can become angry, frustrated, and impatient and that they need help to learn to forgive themselves as well as the loved one they are caring for. Finally, such caregivers must learn how to accept help and should not fear to admit that they cannot carry the burden of care by themselves.

Pick’s disease; 3. primary progressive aphasia; or 4. semantic dementia. Symptoms include personality changes, apathy, compulsive or repetitive behavior, lack of social inhibition, and deterioration in language use. Heller dementiaRegressive autism.HIV-associated dementia See: AIDS-dementia complexdementia with Lewy bodiesA common neurodegenerative disease characterized by gradual and progressive loss of intellectual abilities combined with a movement disorder that resembles Parkinson disease. Those affected often have marked fluctuations in their ability to stay alert and awake and also visual hallucinations. The disease is characterized pathologically by deposits of Lewy bodies. The dementia is treated symptomatically. mixed dementiaDementia in which elements of both Alzheimer disease and vascular dementia are found.multi-infarct dementiaDementia resulting from multiple small strokes. After Alzheimer disease, it is the most common form of dementia in the U.S. It has a distinctive natural history. Unlike Alzheimer disease, which develops insidiously, the cognitive deficits of multi-infarct dementia appear suddenly, in stepwise fashion. The disease is rare before middle age and is most common in patients with hypertension, diabetes mellitus, or other risk factors for generalized atherosclerosis. Brain imaging in patients with this form of dementia shows multiple lacunar infarctions.

The symptoms are apathy, loss of memory, and disturbances of speech and gait. primary dementiaDementia associated with Alzheimer disease. dementia pugilisticaTraumatic dementia, i.e., encephalopathy or an organic brain syndrome caused by closed head injury. It is sometimes referred to colloquially as “boxer's brain.” semantic dementiaAny of a group of brain disorders marked by nearly complete losses in the understanding of word meanings, spelling, and the identification or recognition of facts, faces, or objects. The disease is marked pathologically by local atrophy in the neocortex of the temporal lobe of the brain. senile dementia of the Alzheimer type Abbreviation: SDAT
