Anxiety Disorder Anxiety Disorder Psychiatric Nursing: ANXIETY DISORDER ANXIETY DISORDER ANXIETY • A subjective and individual experience characterized by feeling of apprehension, uneasiness, uncertainty, or dread that warns a person of actual or imagined, misperceived or misinterpreted danger. It is often preceded by new and unknown situations or experiences that threaten the security, self-concept, self-esteem or identity of the person. • It is manifested by both psychological and physiological symptoms • It is a normal response to stressor but no identifiable, specific or certain cause Fear – object can be identified 2 PRIMARY PURPOSES OF ANXIETY 1. Alerts the person to an actual or impending danger 2. Prepares the person to take defensive action (fight or flight) TYPES of ANXIETY 1. Normal – a healthy type of anxiety that mobilizes a person to action 2. Acute – precipitated by imminent loss or change that threatens the sense of security 3. Chronic – anxiety that the individual has lived with for a long time LEVELS OF ANXIETY MILD ANXIETY MODERATE SEVERE PANIC ANXIETY ANXIETY ANXIETY PSYCHOLOGICAL RESPONSES 1 Gerald T.

Evangelista, RN, MAN Psychiatric Nursing: ANXIETY DISORDER Mechanism of Action • Depression of the central nervous system Classification of Anti-Anxiety agents • Benzodiazepines • Buspirone- serotonin and dopamine agonist • Beta-blocker- (Propanolol) BENZODIAZEPINES • Alprazolam (Xanax) • Chlordiazepoxide (Librium) • Clonazepam (Klonopin) • Diazepam (Valium) • Flurazepam (Dalmane) • Lorazepam (Ativan), usually administer for elderly • Oxazepam (Serax), usually administer for elderly Indications of Benzodiazepines • Anxiety • Sedation/sleep • Muscle spasm • Seizure disorder • Alcohol withdrawal symptoms BENZODIAZEPINES • Prolonged use may lead to dependency and abuse 4 Gerald T. Evangelista, RN, MAN Psychiatric Nursing: ANXIETY DISORDER • They appear to increase the effectiveness of GABA and may also alter the brain’s metabolism of serotonin and norepinephrine • All benzodiazepines are readily absorbed in the GI tract after oral administration • The onset of action is very rapid and peak levels are often reached within an hour or less MAJOR INTERACTIONS WITH BENZODIAZEPINES Alcohol and other CNS Depressants • Increased sedation, CNS depression Antacids • Impaired absorption rate of benzodiazepines SIDE EFFECTS OF BENZODIAZEPINES • Drowsiness, confusion, lethargy • Addiction • Potentiates the effects of other CNS depressant • Aggravate symptoms in depressed persons • Orthostatic hypotension • Paradoxical excitement • Nausea PATIENT TEACHING • Benzodiazepines are not for the minor stresses of everyday life. • Over-the-counter drug may potentiate the actions of benzodiazepines • Driving should be avoided until tolerance develops • Alcohol and other CNS depressants potentiate the effects of benzodiazepine 5 Gerald T. Evangelista, RN, MAN Psychiatric Nursing: ANXIETY DISORDER • Hypersensitivity to one benzodiazepine may mean hypersensitivity to another • These drugs should not be stopped abruptly BUSPIRONE (BuSpar) • Is not a benzodiazepine but is from the azapirones chemical group • Does not bind to the benzodiazepine recognition sites but probably acts as serotonin agonist • It causes no sedation thus makes it less attractive for abuse; not habit forming • Not a controlled substance • Does not potentiate the depressant effects of alcohol, barbiturates and other CNS drugs • Because it does not induce an immediate calming effect it should not be used as a prn medication for anxiety • Because of its high cost and slow onset of action, buspirone is not widely prescribed • Haldol and MAOIs may cause some adverse effects when co-administered PROPANOLOL (Inderal) • Beta-blockers have a calming effect on the CNS • Effectively interrupts the physiological responses of anxiety (tremors & tachycardia) • Less effective than benzodiazepines • Relatively safe • Little abuse potential • Bradycardia, light-headedness, and heart block 6 Gerald T. Evangelista, RN, MAN Psychiatric Nursing: ANXIETY DISORDER ANXIETY DISORDERS • Know as neurotic disorders • A group of conditions that share a key feature of excessive anxiety with ensuing behavioral, emotional and physiologic responses • Most common of all psychiatric disorders • The defense mechanism used are repression, displacement and symbolization • Types: 1) General Anxiety Disorder (GAD) 2) Panic disorder 3) OCD 4) Phobic disorder 5) PTSD INCIDENCE • Highest prevalence rate of all mental disorders in the US • More prevalent in women • People younger than 45 years old • People who are separated or divorced • Lower socioeconomic status • Exception in OCD, which is equally prevalent in men and women, but more prevalent among boys than girls ETIOLOGY OF ANXIETY DISORDERS 1. BIOLOGIC THEORIES a. Genetic theories 7 Gerald T. Evangelista, RN, MAN Psychiatric Nursing: ANXIETY DISORDER b. Neurochemical theories • GABA • Gamma- amino butyric acid is believed to be dysfunctional • An inhibitory neurotransmitter • GABA functions as the body’s natural anti- anxiety agent by reducing cell excitability, thus decreasing neuronal firing • NOREPINEPHRINE • Increases anxiety • Related to panic attacks • SEROTONIN • Related to OCD 2. PSYCHODYNAMIC THEORIES A. Psychoanalytic theories • Person’s innate anxiety is the stimulus for behavior • Defense mechanisms are used in an attempt to reduce anxiety B. Interpersonal Theories • Anxiety is generated from problems in interpersonal relationships • The higher the level of anxiety, the lower the ability to communicate and to solve problems C. Behavioral Theory • Anxiety is learned through experiences • Responses to stressors are often the result of learned or conditioned behavior • Individuals who experienced intense fear early in life are likely to be anxious later in life 8 Gerald T. Evangelista, RN, MAN Psychiatric Nursing: ANXIETY DISORDER • When individuals experience too many life changes over a short period of time, they may be unable to adjust and may display maladaptive behavior GENERALIZED ANXIETY DISORDER • Characterized by at least 6 months of persistent and excessive worry and anxiety • Has familial pattern • 60% diagnosed w/ GAD are female • Identified in children and adolescents • Formerly called OVERANXIOUS DISORDER OF CHILDHOOD • Symptoms interfere with normal activities • In an attempt to control the symptoms of GAD, individual sometimes become dependent on alcohol or other substances • Nurses should encourage clients with GAD to rethink their perceptions of the stressor, recognize that some anxiety is a normal part of life, and learn new coping mechanisms • The anxiety and worry are associated with 3 or more of the following 6 symptoms: (REDSIM) • Restlessness • Easily fatigued • Difficulty concentrating • Sleep disturbance • Irritability • Muscle tension 9 Gerald T.

  • Delusions of Parasitosis; an Irrational Fear of Insects Explained
    FACT SHEET DELUSORY PARASITOSIS. THE BELIEF OF BEING LIVED ON BY ARTHROPODS OR OTHER ORGANISMS. Guide for Health Departments, Medical Communities, and Pest Management Professionals Dr. Gale E. Ridge Department of Entomology The Connecticut Agricultural Experiment Station Introduction Delusory parasitosis, an unshakable belief or syndrome (Hopkinson 1970) of being attacked by insects, is a very difficult and under-diagnosed condition. It often starts with an actual event or medical condition (the trigger) that may progress over time into mental illness. For those who have had the problem over long time periods, the condition can sometimes consume a person’s life. Although patients may repeatedly seek help from experts, they may refuse to abandon their ideas for test results which contradict their invested beliefs (Sneddon 1983). Sufferers can become antagonistic and relentless in their need to find someone who will confirm their self-diagnoses (Murray and Ash 2004). Those with the obsession, often search the internet, finding web-sites that support their fears. Often under the falsehood of medical authority, some of these sites provide misguided advice and inaccurate information. Poorly informed misdiagnoses by medical professionals may also contribute to the problem. This is a very complex and difficult condition to manage, requiring dedication and time by trained professionals or an interdisciplinary team of experts. Naming the syndrome Because delusory parasitosis (DP) is medically amorphous, several medical specialists have been involved, e.g., psychiatrists, physicians, dermatologists, and medical entomologists. All have tried to define the condition. The term delusions of parasitosis was coined by Wilson and Miller (1946) dispelling earlier use of the words acarophobia (Thibierge 1894), entomophobia, and parasitophobia.

  • Past Life Regression
    Past Life Regression Past life regression is a technique that uses hypnosis to recover the memories of past lives or incarnations. Past-life regression is typically undertaken either in pursuit of a spiritual experience, or in a psychotherapeutic setting. Most advocates loosely adhere to beliefs about reincarnation, though religious traditions that incorporate reincarnation generally do not include the idea of repressed memories of past lives. The technique used during past-life regression involves the subject answering a series of questions while hypnotized to reveal identity and events of their past lives. The use of hypnosis and suggestive questions can tend to help the subject to recall his past memories. The source of the memories is more likely that of combine experiences, knowledge, imagination and suggestion or guidance from the hypnotist or regression therapist. Once created, those memories are indistinguishable from memories based on events that occurred during the subject's life. Experiments with subjects undergoing past-life regression indicate that a belief in reincarnation and suggestions by the hypnotist are the two most important factors regarding the contents of memories reported. In the 2nd century BC, Sage Patanjali, in his Yoga Sutras, discussed the idea of the soul becoming burdened with an accumulation of impressions as part of the karma from previous lives. Patanjali called the process of past-life regression “prati- prasav”or "reverse birthing" and saw it as addressing current problems through memories of past lives. Past life regression can be found in Jainism. The seven truths of Jainism deal with the soul and its attachment to karma and Moksha.

  • List of Phobias and Simple Cures.Pdf
    Phobia This article is about the clinical psychology. For other uses, see Phobia (disambiguation). A phobia (from the Greek: φόβος, Phóbos, meaning "fear" or "morbid fear") is, when used in the context of clinical psychology, a type of anxiety disorder, usually defined as a persistent fear of an object or situation in which the sufferer commits to great lengths in avoiding, typically disproportional to the actual danger posed, often being recognized as irrational. In the event the phobia cannot be avoided entirely the sufferer will endure the situation or object with marked distress and significant interference in social or occupational activities.[1] The terms distress and impairment as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV-TR) should also take into account the context of the sufferer's environment if attempting a diagnosis. The DSM-IV-TR states that if a phobic stimulus, whether it be an object or a social situation, is absent entirely in an environment - a diagnosis cannot be made. An example of this situation would be an individual who has a fear of mice (Suriphobia) but lives in an area devoid of mice. Even though the concept of mice causes marked distress and impairment within the individual, because the individual does not encounter mice in the environment no actual distress or impairment is ever experienced. Proximity and the degree to which escape from the phobic stimulus should also be considered. As the sufferer approaches a phobic stimulus, anxiety levels increase (e.g. as one gets closer to a snake, fear increases in ophidiophobia), and the degree to which escape of the phobic stimulus is limited and has the effect of varying the intensity of fear in instances such as riding an elevator (e.g.

  • 137 Why Behavior Analysts Should Study Emotion
    JOURNAL OF APPLIED BEHAVIOR ANALYSIS 1998, 31, 137±156 NUMBER 1(SPRING 1998) WHY BEHAVIOR ANALYSTS SHOULD STUDY EMOTION: THE EXAMPLE OF ANXIETY PATRICK C. FRIMAN FATHER FLANAGAN'S BOYS' HOME AND CREIGHTON UNIVERSITY SCHOOL OF MEDICINE AND STEVEN C. HAYES AND KELLY G. WILSON UNIVERSITY OF NEVADA Historically, anxiety has been a dominant subject in mainstream psychology but an in- cidental or even insigni®cant one in behavior analysis. We discuss several reasons for this discrepancy. We follow with a behavior-analytic conceptualization of anxiety that could just as easily be applied to emotion in general. Its primary points are (a) that language- able humans have an extraordinary capacity to derive relations between events and that it is a simple matter to show that neutral stimuli can acquire discriminative functions indirectly with no direct training; (b) that private events can readily acquire discriminative functions; (c) that anxiety disorders seem to occur with little apparent direct learning or that the amount of direct learning is extraordinarily out of proportion with the amount of responding; and (d) that the primary function of anxious behavior is experiential avoidance. We conclude that the most interesting aspects of anxiety disorders may occur as a function of derived rather than direct relations between public events and overt and private responses with avoidance functions. Implicit in this conclusion and explicit in the paper is the assertion that anxiety is a suitable subject for behavior-analytic study. DESCRIPTORS: anxiety, emotion, avoidance, stimulus equivalence, relational frame theory Anxiety is a topic of primary importance orders. There are several peer-reviewed jour- in most approaches to psychopathology.
