Classification of neurotic disorders Flashcards
ICD-10
- 7 headings
- phobic anxiety disorders
- anxiety disorders
- OCD
- reaction to severe stress and adjustment disorders
- dissociative disorders (conversion)
- somatoform disorders and other neurotic disorders
Generalised Anxiety Disorder
- characterised by prominent tension, excessive worry with generalised free-floating persistent anxiety and feelings of apprehension about everyday events leading to significant stress and functional impairment
- duration of 6 months in ICD10
- 22 physical symptoms of anxiety- must have 4 including at least 1 autonomic arousal symtpoms
Panic attack
- discrete episode of intense anxiety
- starts and peaks within 10 minutes and subsides within 20-30 mins
Panic disorder
- recurrent panic attacks which are not secondary to substance missuse, medical conditions or another psychiatric disorder
- may be many a day or few a year
- usually accompanied by persistent worry about having another attack, phobic avoidance of situations
- must be present for 1 months
- severe if more than 4 attacks a week in a 4 week period
- for ICD 10, must occur where there is no danger, not confined to known or predictable situations comparative freedom from anxiety symptoms between attacks
DSM criteria for panic disorder
- at least one panic attack followed by at least one of the following three features for 1 month or more
1. anticipation of further attacks
2. worry about implications
3. avoidance behaviour
Phobic anxiety disorders
- Marks: fear which is out of proportion, cannot be explained, is beyond voluntary control and leads to avoidance
- phobic object is almost always external and not ‘currently dangerous’ to the individual
- if phobic object is internal e.g nosophobia or dysmorphophobia then these conditions are classified under hypochondriasis
Agoraphobia
- commonest phobic disorder seen by psychiatrists and is most incapacitating
- more common in women between the ages of 15-35
- lack of immediate escape route or exit is the main cognitive basis for the anxiety
- distance from home, crowding and confinement are key themes
- anticipatory anxiety can start before the feared situation occurs
- can become completely housebound
- may be accompanied by panic attacks
Social phobia
- ICD 10 recognises 2 types- discrete type and diffuse type
- DSM- social phobia is a marked and persistent fear of one or more social or performance situations where one gets exposed to unfamiliar people or possible close scrutiny of others
Specific phobias
- onset in in childhood
- phobia of animals= 7 years
- blood phobia= 9
- dental phobia=12
- claustrophobia=20
- more common among women
- does not usually fluctuate and remains constant
- being afraid of catching a disease is nosophobia
- for children over 6 months, adult no limit
OCD
-characterised by obsessional thinking, compulsive behaviour and associated with marked anxiety and depression
-ICD10- obsessions and compulsions must be:
1. acknowledged to be originating in the mind
2. repetitive and unpleasant
3 at least one must be unsuccessfully resisted
4. carrying out the obsessive thought or compulsive act is not intrinsically pleasurable
-must be present on most days for a period of at least 2 successive weeks
Obsessions

- obsessional slowness can occur as a result of obsessiona doubts or compulsive rituals
- checking, washing, fear of contamination, doubting, bodily fears, counting, insistence on symmetry, aggressive thoughts
Compulsive hoarding
- may be distinct to OCD
- new to DSM5
- very difficult to treat
Acute stress reaction
-usually starts in an hour
-resolution within 8 hours or 48 hours if prolonged
-patient is often dazed and disorientated
ICD 10 diagnosis
Acute Stress disorder
- DSM 4-similar to ICD10
- can last 2 days to 4 weeks
- marked anxiety and 3 dissociative symptoms
- must involve intense fear, helplessness or horror
Adjustment disorder
- seen in both ICD-10 and DSM 4
- dont meet criteria for PTSD
- psychological reactions arising in relation to adapting to new circumstances and occurs in someone who has been exposed to psychosocial stressor like divorce, separation which is not catastrophic in nature
- usually anxious and depressed
- must be within 1 month for ICD10 or 3 months for DSM 4
- cannot exceed 6 months apart from prolonged depressive reaction
- gradual onset
Bereavement and grief reaction
Patients who experience bereavement within the past 3 months cannot have an adjustment disorder
- normal bereavement is coded in XXI not V
- normal bereavement- hallucinations of widowhood, disbelief, shock, numbness, anger, guiltm sadness, pining, searching
- normal grief reaction lasts up to 12 months with an average duration of 6 months
Stages of Grief
Phase 1- shock and protest ( numbness, disbelief and acute dysphoria
Phase 2-preoccupation (yearning, searching, anger)
Phase 3- disorganisation (despair and acceptance of loss)
Phase 4- resolution (gradual return to normality)
Abnormal grief
-very intense, prolonged, delayed or absent or where symptoms beyond the normal range are seen
-In ICD10 these are coded in adjustment disordes
Inhibited grief-absence of expected grief symptoms at any stage
Delayed grief- avoidance of painful symptoms within the two weeks of loss
Chronic grief- continued significant grief-related symptoms 6 months after loss
-often caused by unexpected deeath, insecure survivor, dependent or ambivalent relationship with the deceased, presence of dependent children and so cannot show grief easily. Presence of previous psychiatric disorder in the survivor
PTSD
- intense prolonged and sometimes delayed reaction to an intensely stressful event
- essential features are hyperarousal, re-experiencing of aspects of the stressful event and avoidance reminders
- Hyperarousal, Hypervigilance and Avoidance
- Both ICD-10 and DSM4 require 2 or more persistent symptoms of increased psychological sensitivity and arousal (not present before exposure to the stressor) to diagnose PTSD
- should start within 6 months of the trauma
Type 1 trauma
Single sudden catastrophic event
Type 2 trauma
Chronic repetitive insult against which the individual has no defence (e.g abuse)
Dissociative (conversion disorders)
- dissociation is referred to as loss of integration among memories, identity, sensations and movements
- occurs closely in time with trauma
- starts suddenly and terminated abruptly within weeks and months
Dissociative amnesia
- centered on the loss of memory for important recent events which is partial, patchy and selective
- retrograde only, no anterograde deficits
- complete inability of memories which were fenerally formed and previously accessible
Dissociative fugue
- purposeful journey away from home occurs. Self care is sually maintained
- sometimes new identity can be assumed
- amnesia is present for past identity during fugue
- there is no cognitve impairment and haviour is normal
- perplexity and la belle indifference are frequent
