ANXIETY Definition of Anxiety • Anxiety is a feeling of apprehension or fear. The source of this uneasiness is not always known or recognized, which can add to the distress you feel.

Situational - situations in which an individual always has an attack, for example, upon entering a tunnel. 3. Situationally Predisposed - situations in which an individual is likely to have a Panic Attack, but does not always have one. An example of this would be an individual who sometimes has attacks while driving. Obsessive-Compulsive Disorder Characterized by uncontrollable obsessions and compulsions which the sufferer usually recognizes as being excessive or unreasonable. • Obsessions are recurring thoughts or impulses that are intrusive or inappropriate and cause the sufferer anxiety: – Thoughts about contamination, for example, when an individual fears coming into contact with dirt, germs or "unclean" objects; – Persistent doubts, for example, whether or not one has turned off the iron or stove, locked the door or turned on the answering machine; – Extreme need for orderliness; – Aggressive impulses or thoughts, for example, being overcome with the urge to yell 'fire' in a crowded theater Obsessive-Compulsive Disorder • Compulsions are repetitive behaviors or rituals performed by the OCD sufferer, performance of these rituals neutralize the anxiety caused by obsessive thoughts, relief is only temporary. – Cleaning.

When the aftermath of a traumatic experience interferes with normal functioning, the person may be suffering from PTSD. • Symptoms of PTSD are: – Reexperiencing the event, which can take the form of intrusive thoughts and recollections, or recurrent dreams; – Avoidance behavior in which the sufferer avoids activities, situations, people,and/or conversations which he/she associates with the trauma; – A general numbness and loss of interest in surroundings; – Hypersensitivity, including: inability to sleep, anxious feelings, overactive startle response, hypervigilance, irritability and outbursts of anger. Social Phobia/Anxiety • Social anxiety disorder, also known as social phobia, is an intense fear of social situations. This fear arises when the individual believes that they may be judged, scrutinized or humiliated by others. • Individuals with the disorder are acutely aware of the physical signs of their anxiety and fear that others will notice, judge them, and think poorly of them. • In extreme cases this intense uneasiness can progress into a full blown panic attack.

Several factors can play a role – Genetics – Brain biochemistry – Overactive "fight or flight" response • Can be caused by too much stress – Life circumstances – Personality • People who have low self-esteem and poor coping skills may be more prone • Certain drugs, both recreational and medicinal, can lead to symptoms of anxiety due to either side effects or withdrawal from the drug. • In very rare cases, a tumor of the adrenal gland (pheochromocytoma) may be the cause of anxiety.

Olfactory and tactile stimuli: Smells and touch sensations Bypass the thalamus altogether, Taking a shortcut directly to the Amygdala. Smells, therefore, Often evoke stronger memories Or feelings than do sights or Sounds. Physical Reaction to Anxiety Thalamus: The hub for sights and sounds, The thalamus breaks down Incoming visual cues by size, Shape and color, and auditory Cues, by volume and Dissonance, and then signals The appropriate part of the Cortex. Cortex: It gives raw sights and sounds meanings, enabling the brain to become conscious of what it Is seeing or hearing. One region, the prefrontal cortex, may be vital to turning off the anxiety response once a threat has passed. Physical Reaction to Anxiety Amygdala: emotional core of the brain, the amygdala has the primary role of triggering the fear response. information that passes through the amygdala is tagged with emotional significance. Bed Nucleus of Stria Terminalis: unlike the Amygdala, which sets off an immediate burst of fear, the BNST perpetuates the fear response, causing the longer term unease typical of anxiety. Physical Reaction to Anxiety Locus Ceruleus: It receives signals from the amygdala and is responsible for initiating many of the classic anxiety responses: rapid heartbeat, increased blood pressure, sweating and pupil dilation. Hippocampus: This is the memory center, vital to storing the raw information coming in from the senses along with the emotional baggage attached to the data during their trip through the amygdala.
