Generalised Anxiety, Panics, Phobias, OCD Flashcards
(58 cards)
Model of emotional disorders?
Cognition, behaviour, biology and emotions are all affected by environmental input
Physical symptoms of anxiety?
Occur due to sympathetic over-activity:
• Sweating, hot flushes or cold chills
• Trembling or shaking
• Muscle tensions, aches and pains
• Numbness and tingling
• Dizziness, unsteady, faint, light-headed
• Dry mouth that is not due to drugs or dehydration
• Feeling of choking
• Sensation of a throat lump or sensation of dysphagia
• Difficulty breathing
• Palpitations, pounding and accelerated HR
• Nausea or abdominal distress (churning in stomach)
Cognitive symptoms of anxiety?
Feeling of losing control, keyed up, on edge or mentally tense
Difficulty in concentrating
Hypervigilance (internal and external)
Racing thoughts
Meta-worry (about everything, inc. anxiety itself)
Hypochondriasis
Preference for order and routine
Behavioural symptoms of anxiety?
Avoidance of certain situations
Exaggerated response to minor surprises of being startled
Difficulty sleeping
Excessive alcohol consumption or drug use
Restlessness or an inability to relax
Persistent irritability
Seek reassurance from family / GP
Checking behaviours
Describe the stress response
Exposure to stress results in instantaneous and concurrent biological responses:
• To assess danger
• To organise and appropriate response
Role of the amygdala in the stress response?
Acts as the emotional filter of the brain, to assess whether than sensory material via the thalamus require a stress/fear response (takes milliseconds)
NOTE - this is modified by a cortically processed signal that is received later (‘act first, think later)
Which hormones are released due to acute stress?
Dose-dependent increased in:
• Catecholamines
• Cortisol (acts to mediate and shutdown the stress response; via -ve feedback, it acts on the pituitary, hypothalamus, hippocampus and amygdala, which are responsible for stimulation of cortisol release)
i.e: acute stress increases cortisol levels
How to differentiate anxiety from anxiety disorder?
Anxiety is pathology, i.e: a disorder, when it is more extreme than ‘normal’ (in extent) and in situations that are not ‘normally’ anxiety-provoking (in context)
It causes significant distress and impairment of social / occupational / other functions
Types of anxiety disorders?
Generalised anxiety disorder
Panic disorder
Agoraphobia
Social phobia
Specific phobia (not always assoc. with anxiety)
OCD
What is generalised anxiety disorder?
Anxiety that is GENERALISED and PERSISTENT but is not restricted to, or even strongly dominant in, any part. environmental circumstances
It is not due to substance misuse or another medical conditions, e.g: hyperthyroidism
Dominant symptoms in generalised anxiety disorder?
Persistent nervousness
Trembling
Muscular tensions
Sweating
Light-headedness and dizziness
Palpitations
Epigastric discomfort
Often, patients express fear that they or a relative will shortly become ill or have an accident
3 general requirements for how severe generalised anxiety disorder must be?
Needs to be severe enough to be:
• Long lasting (most days in a 6 month period)
• Uncontrollable
• Causing significant distress / impairment in function
What signs is generalised anxiety disorder typically assoc. with?
Restlessness or feeling of being keyed up or on edge
Being easily fatigued
Difficult conc. or mind going blank
Irritability
Muscle tension
Sleep disturbance (difficulty falling or staying asleep and restless / unsatisfying sleep)
Occurrence of generalised anxiety disorder?
Typical age of onset if 20-40 years
More common in females
Has a chronic, fluctuating course, i.e: better sometimes and worse at others
Clues that a patient may have GAD?
Assoc. with disability, MUS and over-utilisation of health care services
Cormorbidities with GAD?
90% of patients have comorbidities with other psychiatric disorders, e.g: depression, substance abuse, other anxiety disorders
Treatment of GAD?
CBT is the main and preferred choice
SSRIs / SNRIs or pregabalin may be used
Benzodiazepines are very effective but are only ever used SHORT-TERM
What is CBT?
Evidence-based psychological treatment
It is based on identifying a patient’s automatic thoughts, cognitive biases and schemas; this helps the patient identify their thoughts, assumptions, misinterpretations and behaviours that reinforce and perpertuate anxiety
What is panic disorder?
Essential feature is recurrent attacks of sudden, severe anxiety (i.e: panic); this is not restricted to any part. situation or set of circumstances and so they are UNPREDICTABLE
It is not due to direct physiological effects of a drug or general medical conditions, e.g: hyperthyroidism, caffeine intoxication
It is also not better accounted for by another mental disorder, e.g: depression
Dominant symptoms of panic disorder?
Sudden onset of palpitations, chest pain, choking sensations, dizziness and feelings of unreality (depersonalisation and derealisation)
Often, there is a fear of dying, losing control or going mad that occurs secondary to the symptoms
Features assoc. with panic disorder?
May occur with / without agoraphobia
Occurrence of panic disorder?
Typical onset is late adolescence to mid-30s
Many of these patients have agoraphobia
Typical course of panic disorder?
Chronic (waxing and waning)
Co-morbidities with panic disorder?
Other anxiety disorders, depression, drug and alcohol misuse
