These techniques include: meditation, deep breathing exercises, long baths, resting in the dark, and yoga. • Exercises to replace negative thoughts with positive ones: Make a list of the negative thoughts that might be cycling as a result of anxiety, and write down another list next to it containing positive, believable thoughts to replace them.

Patients can learn to overcome deep-seated fears by facing them head-on. • Counseling A standard way of treating anxiety is psychological counseling. This can include cognitive-behavioral therapy (CBT), psychotherapy, or a combination of therapies. Cognitive behavioral therapy is a first-line, evidence-based approach for anxiety. CBT helps you identify distorted or negative thinking patterns, and find more positive, effective ways to respond. 9 11/11/2019 Cognitive behavioral therapy (CBT) Engaging with CBT can help people reduce stress, cope with complicated relationships, deal with grief, and face many other common life challenges. • CBT is a structured psychological treatment which recognizes that the way we think (cognition) and act (behaviour) affects the way we feel. • For example, a psychotherapist providing CBT for panic disorder will try to reinforce the fact that panic attacks are not really heart attacks. • Exposure to fears and triggers can be a part of CBT. This encourages people to confront their fears and helps reduce sensitivity to their usual triggers of anxiety. • Cognitive-behavioral therapy helps people with mental illness to identify and change inaccurate perceptions that they may have of themselves and the world around them. The therapist helps the patient establish new ways of thinking by directing attention to both the "wrong" and "right" assumptions they make about themselves and others. • Some forms of psychotherapy focus on looking into the past to gain an understanding of current feelings. In contrast, CBT focuses on present thoughts and beliefs and challenges . 10 11/11/2019 Changing distortions and perceptions • • • • • • • • CBT can help people to find new ways of looking at things by changing: a negative mindset jumping to conclusions mistakenly seeing situations as catastrophic seeing things as either good or bad with nothing in between distinguish between facts and irrational thoughts better understand other people's actions and motivations avoid generalizations and all-or-nothing thinking establish attainable goals 11 11/11/2019 Medications Medicines that might control some of the physical and mental symptoms include antidepressants, benzodiazepines, tricyclics, and beta-blockers. • Benzodiazepines : A doctor may prescribe these for certain people with anxiety, but they can be highly addictive. These drugs tend to have few side effects except for drowsiness and possible dependence. Diazepam, or Valium, is an example of a commonly prescribed benzodiazepine. It should be withdraw slowly because some patient have difficulty in stopping the drug. • Tricyclics: This is a class of drugs older than SSRIs that provide benefits for most anxiety disorders other than OCD. These drugs might cause side effects, including dizziness, drowsiness, dry mouth, and weight gain. • Antidepressants (serotonin reuptake inhibitors (SSRI): These commonly help with anxiety, even though they also target depression. 12 11/11/2019 Adverse effects Uses Sexual side effects antidepressants Cardiovascular side effects anxiety disorders Discontinuation syndrome personality disorders Example Prozac begin with 20mg in the morning and gradually increase to 40 mg SSRI’s • With SSRIs treatment should start at a very low dose. Doubling of the initial dose should occur every 5 days as tolerated. Explain to the patient that they will have jerky (jumpy) or nervous actions , nausea and headache but these symptoms will usually resolve within 1 to 2 weeks of starting the treatment. Also it can make sexual dysfunction which will occur in 20 to 35% of patients . If it occurs the dosage may have to be decreased or the medication changed. 13 11/11/2019 Discontinuation syndrome (withdrawal) • When coming off of antidepressants (cessation), individuals can experience withdrawal syndrome. This can highly resemble the symptoms of depression, such as low mood and feeling suicidal. This can make people feel that they are relapsing and become depressed again, which can in turn lead to them starting back on their antidepressants when actually they are not needed. • Guidelines recommend short tapers, of between 2 weeks and 4 weeks, down to therapeutic minimum doses, or half-minimum doses, before complete cessation. 14 11/11/2019 Prevention • • • • • Take the following steps to help moderate anxious emotions: Reduce intake of caffeine, tea, cola, and chocolate.

Panic disorder can be characterized by: • The presence of recurring and unexpected („out of the blue‟) panic attacks. • Worrying for at least a month after having a panic attack that you will have another one. • Worrying about the implications or consequences of a panic attack (such as thinking that the panic attack is a sign of an undiagnosed medical problem). For example, some people have repeated medical tests due to these worries and, despite reassurance, still have fears of being unwell. • Significant changes in behaviour that relate to the panic attacks (such as avoiding activities like exercise because it increases the heart rate). • Panic attacks reach a peak within about 10 minutes and usually last for up to half an hour, leaving you feeling tired or exhausted. They can occur several times a day or may happen only once every few years. They can even occur while people are asleep, waking them up. Many people experience a panic attack once or twice in their lives; this is common and is not panic disorder. The attack must be followed by at least a one month persistent concern about having additional attacks and worry about the implication of the attack. 16 11/11/2019 Panic attack symptoms A sense of overwhelming panic or fear Sudden, intense episode of apprehension رعب, terror, feelings, of impending doom and dread ( ) فزع. The need to escape. Symptoms reach peak intensity within 10 minutes Accompanied by at least 4 other symptoms: Heart palpitations, sweating, nausea, shortness of breath, , dizziness, upset stomach, lightheadedness, etc. Other symptoms may include: • Depersonalization • Derealization ; a sense that you or the world around you is not real (Feeling of unreality or being detached from one’s self) • Fear of going crazy, losing control, or dying People having panic attacks sometimes believe they are having heart attacks, losing their minds, or on the verge of death. 17 11/11/2019 18 11/11/2019 Causes of panic disorder • Panic disorders usually occur after frightening experiences or prolonged stress but may also occur without a trigger. An individual experiencing a panic attack may misinterpret it as a lifethreatening illness, and may make drastic changes in behavior to avoid future attacks. Management of panic attack • Cognitive behavioral therapy can help him learn, through his own experience, that panic symptoms are not dangerous. • Medications: - B blocker - SSRI’s 19 11/11/2019 Specific Phobias • Fear is a rational response to situations that can pose a threat to our safety. • However, some people react to objects, activities or situations (the phobic stimulus) by imagining or irrationally exaggerating the danger. Their feelings of panic, fear or terror are completely out of proportion to the actual threat. Sometimes the thought of the phobic stimulus, or the sight of it on TV, is enough to cause a reaction. These types of excessive reactions may be indicative of a specific phobia. • People with specific phobias are often well aware that their fears are exaggerated or irrational, but feel that their anxious reaction is automatic or uncontrollable. Specific phobias are often associated with panic attacks, during which the person experiences overwhelming physical sensations that may include a pounding heart, choking, nausea, faintness, dizziness, chest pain, hot or cold flushes and perspiration. 20 11/11/2019 • They have a persistent, excessive and unreasonable fear of a specific object, activity or situation, e.g. heights, the sight of blood or encountering a dog. • Avoid situations where you may have to face the phobic stimulus, e.g. not walking down a street where there may be a dog. If the situation is unavoidable, you're likely to feel high levels of distress. • Find that the anxiety or avoidance associated with such situations makes it difficult to go about daily life (e.g. interferes with working, studying or seeing friends and family). • The anxiety and avoidance are persistent and have been present for at least 6 months or more 21 11/11/2019 Specific phobias are generally divided into the following categories: • Animal type: fear that relates to animals or insects (e.g. fear of dogs or spiders). • Natural environment type: fear associated with the natural environment (e.g. fear of thunder or heights storms, or water) generally has a childhood onset. • Blood/injection/injury type: fear associated with invasive medical procedures (e.g. injections), or with seeing blood or injury. • Situational type: fear of specific situations (e.g. elevators, bridges or driving). • Other: any other specific phobias (e.g. fear of choking, fear of vomiting). Blood-injury phobia or Vasovagal Syncope • “Blood-injury phobia” is a curious type of specific phobia with distinct clinical features. Exposure to phobic cues induces tachycardia in most phobias. Blood-injury phobia patients typically experience a response of an initial tachycardia, followed by bradycardia, hypotension, shock, vertigo, syncope. This response is peculiar to blood phobia and is not a characteristic of other specific phobias (fight and flight). • Vasovagal syncope is a common cause of fainting. The vagus nerve is over stimulated and causes the body's blood vessels to dilate and the heart to slow down. This anti-adrenaline effect decreases the ability of the heart to pump blood upward to the brain against gravity. Without blood flow, the brain turns off. It is familial . 22 11/11/2019 Agoraphobia • Anxiety about or avoidance of, places or situations from which escape might be difficult (or embarrassing) or in which be available in the event of having a Panic Attack or panic-like symptoms.

People often misunderstand this condition as a phobia of open spaces and the outdoors, but it is not so simple. A person with agoraphobia may have a fear of leaving home or using elevators and public transport. Nearly all patients with agoraphobia have panic attacks. 23 11/11/2019 Generalized anxiety disorder (GAD) • It is characterized by excessive and persistent worrying that is hard to control, causes significant distress or impairment, and • occurs for more than six months at least. • It’s the worst anxiety • Non specific fear • People with GAD, however, feel anxious and worried most of the time, not just in specific stressful situations, and these worries are intense, persistent and interfere with their normal lives. Their worries relate to several aspect of everyday life, including work, health, family and/or financial issues, rather than just one issue. Even minor things such as household activites or being late for an appointment can become the focus of anxiety, leading to uncontrollable worries and a feeling that something terrible will happen. 24 11/11/2019 Signs and symptoms: The symptoms of generalized anxiety disorder fluctuate. You may notice better and worse times of the day, or better and worse days in general. And while stress doesn’t cause generalized anxiety disorder, it can make the symptoms worse. Not everyone with generalized anxiety disorder has the same symptoms. But most people with GAD experience a combination of a number of the following emotional, behavioral, and physical symptoms.

Cognitive behavioral therapy • Cognitive behavioral therapy has benefits that go beyond just helping to reduce anxiety. It can also help with the symptoms of depression, for example, which may accompany generalized anxiety disorder. 26 11/11/2019 Obsessive Compulsive Disorder (OCD): Obsessive-compulsive disorder (OCD) is characterized by unreasonable thoughts and fears (obsessions) that lead him to do repetitive behaviors + rituals affects his life + repeated thoughts • Although the person may acknowledge these thoughts as silly, they often try to relieve their anxiety by carrying out certain behaviours or rituals. For example, a fear of germs and contamination can lead to constant washing of hands and clothes. 27 11/11/2019 Signs and symptoms: Most people with obsessive-compulsive disorder (OCD) have both obsessions and compulsions, but some people experience just one or the other. Obsessive thoughts Common obsessive thoughts include: Fear of being contaminated by germs or dirt or contaminating others Fear of causing harm to himself or others Intrusive bad or violent thoughts and images Excessive focus on religious or moral ideas Fear of losing or not having things that might need order and symmetry: the idea that everything must line up “just right” Superstitions مشعوذexcessive attention to something considered lucky or unlucky Compulsive behaviors Common compulsive behaviors in (OCD) include: Excessive double-checking of things, such as locks, appliances, and switches Repeatedly checking in on loved ones to make sure they‟re safe Counting, tapping, repeating certain words, or doing other senseless things to reduce anxiety Spending a lot of time washing or cleaning Ordering or arranging things “just so” Praying excessively or engaging in rituals triggered by religious fear Accumulating “junk” such as old newspapers or empty food containers 28 11/11/2019 Selective serotonin re-uptake inhibitors (SSRIs): • Selective serotonin re-uptake inhibitors are antidepressants. They can relieve anxiety symptoms. Cognitive behavioral therapy • Cognitive behavioral therapy has benefits that go beyond just helping to reduce anxiety using Exposure and Response Prevention (ERP) which is a type of CBT. 29 11/11/2019 What is Exposure and Response Prevention? • For OCD use the most important type of CBT Exposure and Response Prevention (ERP). • The Exposure in ERP refers to exposing patient to the thoughts, images, objects and situations that make him anxious and/or start your obsessions. While the Response Prevention part of ERP, refers to making a choice not to do a compulsive behavior once the anxiety or obsessions have been “triggered Post-Traumatic Stress Disorder (PTSD): What is PTSD? • Post-traumatic stress disorder (PTSD) is a particular set of reactions that can develop in people who have been through a traumatic event which threatened their life or safety, or that of others around them. This could be a car or other serious accident, physical or sexual assault, war, or disasters such as bushfires or floods. As a result, the person experiences feelings of intense fear, helplessness or horror. 30 11/11/2019 • People with PTSD often experience feelings of panic or extreme fear, similar to the fear they felt during the traumatic event. A person with PTSD experiences four main types of difficulties. 1- Re-living the traumatic event – The person relives the event through unwanted and upsetting memories, often in the form of vivid images (flashbacks), frightening thoughts and nightmares. There may be intense emotional or physical reactions, such as sweating, heart palpitations or panic when reminded of the event. 31 11/11/2019 2- Being overly alert or wound up: The person experiences sleeping difficulties, irritability and lack of concentration, becoming easily irritated and constantly on the lookout for signs of danger. 3- Avoiding reminders of the event: The person deliberately avoids activities, places, people, thoughts or feelings associated with the event because they bring back painful memories. 4- Hyperarousal symptoms (abnormal state of increased responsiveness to stimuli ) - Feeling tense or “on edge” - Having difficulty sleeping, and/or having angry outbursts. - Feeling emotionally numb not able to feel any emotions or to think clearly, – The person loses interest in day-to-day activities, feels cut off and detached from friends and family, or feels emotionally flat and numb. 32 11/11/2019 • Hyperarousal is the abnormally heightened state of anxiety that occurs whenever you think about a traumatic event. Even though the threat may no longer be present, your body will respond as if it were. Hyperarousal symptoms are usually constant, instead of being triggered by things that remind one of the traumatic event. They can make the person feel stressed and angry. These symptoms may make it hard to do daily tasks, such as sleeping, eating, or concentrating. 33 11/11/2019 Management • Short- and longterm psychotherapy and medications can work very well. Often, the two kinds of treatment are more effective together. • Most PTSD therapies fall under the umbrella of cognitive behavioral therapy (CBT). The idea is to change the thought patterns that are disturbing your life. This might happen through talking about your trauma or concentrating on where your fears come from. • Prolonged Exposure Therapy • If he is avoiding things that remind him of the traumatic event, PE will help him confront them. It involves eight to 15 sessions, usually 90 minutes each. • Early on in treatment, therapist will teach him breathing techniques to ease his anxiety when he think about what happened. • Later, he will make a list of the things he have been avoiding and learn how to face them, one by one. • In another session, he will record the traumatic experience to his therapist, then go home and listen to a recording of him self. • Doing this as "homework" over time may help ease symptoms. 34 11/11/2019 Social Anxiety Disorder: • It's perfectly normal to feel nervous in social situations where we might come under the attention of others, whether they're strangers or people we know. Attending a formal function, giving a speech at a wedding, doing a presentation to work colleagues are likely to cause nervousness and anxiety, both in the lead-up and during the event. • However, for people with social phobia (sometimes known as social anxiety disorder), performing in front of others and social situations can lead to intense anxiety. They may fear being judged, criticised, laughed at or humiliated in front of others, even in the most ordinary, everyday situations. • A person with social anxiety disorder is afraid that he or she will make mistakes, look bad, and be embarrassed or humiliated in front of others 35 11/11/2019 Signs and symptoms: Emotional symptoms of social anxiety disorder / social phobia - Intense worry for days, weeks, or even months before an upcoming social situation - Extreme fear of being watched or judged by others, especially people you don’t know - Fear that you’ll act in ways that that will embarrass or humiliate yourself - Fear that others will notice that you’re nervous - Physical symptoms of social anxiety disorder / social phobia - Red face, or blushing - Shortness of breath - Upset stomach, nausea - Trembling or shaking (including shaky voice) - Racing heart or tightness in chest - Sweating or hot flashes - Feeling dizzy or faint 36 11/11/2019 Terrified female speaker on the stage Treatment • Social phobia is treatable and seeking professional support is the first step to recovery. There are two main types of effective treatments for social phobia; psychological treatments will generally be the first line of treatment. In some severe cases, medication can also be effective. 37 11/11/2019 • References: • South-Paul J, Matheny S Lewis E. Current diagnosis and treatment in Family medicine. 4th ed.
