Benzodiazepine Dependence
Benzodiazepine dependence (BZD dependence) defines a situation in which one has developed one or more of either tolerance, withdrawal symptoms, drug seeking behaviors, such as continued use despite harmful effects, and maladaptive pattern of substance use, according to the DSM-IV. In the case of benzodiazepine dependence, the continued use seems to be typically associated with the avoidance of unpleasant withdrawal reaction rather than with the pleasurable effects of the drug. Benzodiazepine dependence develops with long-term use, even at low therapeutic doses, often without the described drug seeking behavior and tolerance. Addiction consists of people misusing or craving the drug, not to relieve withdrawal symptoms, but to experience its euphoric or intoxicating effects. It is necessary to distinguish between addiction to and abuse of benzodiazepines, and physical dependence on them. The increased GABA inhibition on the neural systems caused by benzodiazepines is counteracted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorazepam
Lorazepam, sold under the brand name Ativan, Tavor among others, is a benzodiazepine medication. It is used to treat anxiety (including anxiety disorders), insomnia, severe agitation, active seizures including status epilepticus, alcohol withdrawal, and chemotherapy-induced nausea and vomiting. It is also used during surgery to interfere with memory formation, to sedate those who are being mechanically ventilated, and, along with other treatments, for acute coronary syndrome due to cocaine use. It can be given orally (by mouth), transdermally (on the skin via a topical gel or patch), intravenously (injection into a vein), or intramuscularly (injection into a muscle). When given by injection, onset of effects is between one and thirty minutes and effects last for up to a day. Common side effects include weakness, sleepiness, ataxia, decreased alertness, decreased memory formation, low blood pressure, and a decreased effort to breathe. When given intraveno ...

Derealization
Derealization is an alteration in the perception of the external world, causing those with the condition to perceive it as unreal, distant, distorted, or in other ways falsified. Other symptoms include feeling as if one's environment lacks spontaneity, emotional coloring, and depth. Described as "Experiences of unreality or detachment with respect to surroundings (e.g., individuals or objects are experienced as unreal, dreamlike, foggy, lifeless or visually distorted") in the DSM-5, it is a dissociative symptom that may appear in moments of severe stress. Derealization is a subjective experience pertaining to a person's perception of the outside world, while depersonalization is a related symptom characterized by dissociation from one's own body and mental processes. The two are commonly experienced in conjunction but can also occur independently. Chronic derealization is fairly rare, and may be caused by occipital– temporal dysfunction. Experiencing derealization for long pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory Clinic
A memory clinic is a dedicated medical clinic specialising in the assessment and diagnosis of memory disorders. Memory clinics were first seen in the UK in the 1980s, mainly in academic research centres. There are by 2009 approximately 246 memory clinics but there are no official NHS figures and no specific standards or set models relating to them. The National Service Framework A National Service Framework (NSF) was any of several policies set by the National Health Service (NHS) in England to define standards of care for major medical issues such as cancer, coronary heart disease, chronic obstructive pulmonary disease, ... (NSF) for Older People stipulates that every specialist mental health service for older people should have a memory clinic (article 7.49) but it gives no specific guidelines for establishing one.

Benzodiazepines
Benzodiazepines (BZD, BDZ, BZs), colloquially known as "benzos", are a class of central nervous system (CNS) depressant drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. They are prescribed to treat conditions such as anxiety disorders, insomnia, and seizures. The first benzodiazepine, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955, and was made available in 1960 by Hoffmann–La Roche, which followed with the development of diazepam (Valium) three years later, in 1963. By 1977, benzodiazepines were the most prescribed medications globally; the introduction of selective serotonin reuptake inhibitors (SSRIs), among other factors, decreased rates of prescription, but they remain frequently used worldwide. Benzodiazepines are depressants that enhance the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABAA receptor, resulting in sedative, hypnotic ( sleep-inducing), anxiolyt ...

Drug Dependence
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption of the drug. A ''drug addiction'', a distinct concept from substance dependence, is defined as compulsive, out-of-control drug use, despite negative consequences. An ''addictive drug'' is a drug which is both rewarding and reinforcing. ΔFosB, a gene transcription factor, is now known to be a critical component and common factor in the development of virtually all forms of behavioral and drug addictions, but not dependence. The International Classification of Diseases classifies substance dependence as a mental and behavioural disorder. In the ''Diagnostic and Statistical Manual of M ...

Drug Misuse
Substance misuse, also known as drug misuse or, in older vernacular, substance abuse, is the use of a drug in amounts or by methods that are harmful to the individual or others. It is a form of substance-related disorder, differing definitions of drug misuse are used in public health, medical, and criminal justice contexts. In some cases, criminal or anti-social behavior occurs when some persons are under the influence of a drug, and may result in long-term personality changes in individuals which may also occur. In addition to possible physical, social, and psychological harm, the use of some drugs may also lead to criminal penalties, although these vary widely depending on the local jurisdiction.. Drugs most often associated with this term include alcohol, amphetamines, barbiturates, benzodiazepines, cannabis, cocaine, hallucinogens, methaqualone, and opioids. The exact cause of substance abuse is sometimes clear, but there are two predominant theories: either a genetic pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elderly
Old age is the range of ages for people nearing and surpassing life expectancy. People who are of old age are also referred to as: old people, elderly, elders, senior citizens, seniors or older adults. Old age is not a definite biological stage: the chronological age denoted as "old age" varies culturally and historically. Some disciplines and domains focus on the aging and the aged, such as the organic processes of aging ( senescence), medical studies of the aging process (gerontology), diseases that afflict older adults ( geriatrics), technology to support the aging society (gerontechnology), and leisure and sport activities adapted to older people (such as senior sport). Older people often have limited regenerative abilities and are more susceptible to illness and injury than younger adults. They face social problems related to retirement, loneliness, and ageism. In 2011, the United Nations proposed a human-rights convention to protect old people. History European T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcohol (drug)
Alcohol, sometimes referred to by the chemical name ethanol, is the active ingredient in alcoholic drinks such as beer, wine, and distilled spirits (hard liquor). Alcohol is a central nervous system (CNS) depressant, decreasing Action potential, electrical activity of neurons in the brain, which causes the characteristic effects of alcohol intoxication ("drunkenness"). Among other effects, alcohol produces euphoria, anxiolytic, decreased anxiety, increased sociability, sedation, and impairment of cognitive, memory, motor control, motor, and sense, sensory function. Alcohol has a variety of adverse effects. Short-term effects of alcohol consumption, Short-term adverse effects include generalized impairment of neurocognitive function, dizziness, nausea, vomiting, and symptoms of hangover. Alcohol is addiction, addictive and can result in alcohol use disorder, Substance dependence, dependence, and Alcohol withdrawal syndrome, withdrawal upon cessation. The long-term effects of ...

Tobacco
Tobacco is the common name of several plants in the genus '' Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word 'tobacco' originates from the Spanish word ''taba ...

Cognitive Reserve
Cognitive reserve is the mind's and brain's resistance to damage of the brain. The mind's resilience is evaluated behaviorally, whereas the neuropathological damage is evaluated histologically, although damage may be estimated using blood-based markers and imaging methods. There are two models that can be used when exploring the concept of "reserve": ''brain reserve'' and ''cognitive reserve''. These terms, albeit often used interchangeably in the literature, provide a useful way of discussing the models. Using a computer analogy, brain reserve can be seen as hardware and cognitive reserve as software. All these factors are currently believed to contribute to global reserve. Cognitive reserve is commonly used to refer to both brain and cognitive reserves in the literature. In 1988 a study published in ''Annals of Neurology'' reporting findings from post-mortem examinations on 137 elderly persons unexpectedly revealed that there was a discrepancy between the degree of Alzheimer's di ...
