Anxiety disorder
Anxiety disorders are a group of mental disorders characterized by significant feelings of anxiety and fear. Anxiety is a worry about future events and fear is a reaction to current events. These feelings may cause physical symptoms, such as a fast heart rate and shakiness. There are a number of anxiety disorders: including generalized anxiety disorder, specific phobia, social anxiety disorder, separation anxiety disorder, agoraphobia, panic disorder, and selective mutism. The disorder differs by what results in the symptoms. People often have more than one anxiety disorder. The cause of anxiety disorders is a combination of genetic and environmental factors.
Social anxiety disorder
Social anxiety disorder (SAD), also known as social phobia, is an anxiety disorder characterized by a significant amount of fear in one or more social situations, causing considerable distress and impaired ability to function in at least some parts of daily life. These fears can be triggered by perceived or actual scrutiny from others. Physical symptoms often include excessive blushing, excess sweating, trembling, palpitations, and nausea. Stammering may be present, along with rapid speech. Panic attacks can also occur under intense fear and discomfort. Some sufferers may use alcohol or other drugs to reduce fears and inhibitions at social events.
Separation anxiety disorder
Separation anxiety disorder (SAD), is an anxiety disorder in which an individual experiences excessive anxiety regarding separation from home or from people to whom the individual has a strong emotional attachment (e.g., a parent, caregiver, significant other or siblings). It is most common in infants and small children, typically between the ages of 6–7 months to 3 years, although it may pathologically manifest itself in older children, adolescents and adults. Separation anxiety is a natural part of the developmental process. Unlike SAD (indicated by excessive anxiety), normal separation anxiety indicates healthy advancements in a child's cognitive maturation and should not be considered a developing behavioral problem.
Generalized anxiety disorder
Generalized anxiety disorder (GAD) is an anxiety disorder characterized by excessive, uncontrollable and often irrational worry, that is, apprehensive expectation about events or activities. This excessive worry often interferes with daily functioning, as individuals with GAD typically anticipate disaster, and are overly concerned about everyday matters such as health issues, money, death, family problems, friendship problems, interpersonal relationship problems, or work difficulties. Individuals may exhibit a variety of physical symptoms, including feeling tired, fidgeting, headaches, numbness in hands and feet, muscle tension, difficulty swallowing, upset stomach, vomiting, diarrhea, breathing difficulty, difficulty concentrating, trembling, irritability, sweating, restlessness, sleeping difficulties, hot flashes, rashes, and inability to fully control the anxiety.
Anxiety
Anxiety is an emotion characterized by an unpleasant state of inner turmoil, often accompanied by nervous behavior, such as pacing back and forth, somatic complaints, and rumination. It is the subjectively unpleasant feelings of dread over anticipated events, such as the feeling of imminent death. Anxiety is not the same as fear, which is a response to a real or perceived immediate threat, whereas anxiety is the expectation of future threat. Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing.
Panic disorder
Panic disorder is an anxiety disorder characterized by recurrent unexpected panic attacks. Panic attacks are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, numbness, or a feeling that something really bad is going to happen. The maximum degree of symptoms occurs within minutes. There may be ongoing worries about having further attacks and avoidance of places where attacks have occurred in the past. The cause of panic disorder is unknown. Panic disorder often runs in families. Risk factors include smoking, psychological stress, and a history of child abuse.
Caffeine-induced anxiety disorder
Caffeine-induced anxiety disorder is an anxiety disorder that can be present in people susceptible to panic attacks and anxiety. Consumption of caffeine has long been linked to anxiety. Caffeine-induced anxiety disorder, however, almost exclusively occurs in people who already have an anxiety disorder. For these people, they are more prone to the psychological effects of caffeine and are at greater risk of a panic attack after ingesting non-trivial amounts of caffeine. The effects of caffeine and the symptoms of anxiety both increase activity within the sympathetic nervous system. Caffeine has been linked to the aggravation and maintenance of anxiety disorders, and the initiation of panic or anxiety attacks in those who are already predisposed to such phenomena.
