ICD10 diagnostic criteria for AN:
- BMI <17.5 (or weight less than 15% expected weight)
- deliberate weight loss
- fear of fat/distorted body image
(should have no endocrine dysfunction)
How do you calculate BMI

What is the weight of BN and AN?
AN - underweight
BN - normal weight (BMI > 17.5)
Can there be binging and purging in AN?
Yes
3 diagnostic criteria for Bulimia:
1) Binging or persistent preoccupation with eating and/or irresistible craving for food
2) Purging behaviours (diuretics, excessive exercise, laxatives, insulin therapy, vomiting)
3) Psychotherapy (feeling loss of control, morbid dread of fatness)
Signs and symptoms of Bulimia:
- Less severe but similar to anorexia
- Amenorrhoea despite normal weight
What is binge eating disorder?
Most common eating disorder but no purging pathology
Differential for Bulimia:
upper GI disorder, personality disorder, depressive disorder, obesity
Management for bulimia? (mild)

- Screen for immediate admission otherwise manage in the community
- Guided self-help, recommend BEAT charity, monitor for 8 weeks
- Routine referral to CEDS if failure to respond
FEATURES: frequent binging and purging (> 2 weeks), some medical consequences such as chest pain
Management for bulimia? (severe)
- Screen for immediate admission otherwise manage in the community
- Urgent referral to CEDS (community eating disorder service)

SSRIs (high dose 60mg fluoxetine) –> reduce binging and purging and helps impulses
Plan for children and adults (therapy) in bulimia.
Children: 1st line - family therapy
Adults: 1st line - Guided self-help programmed; 2nd line - CBT-ED
Investigations for Bulimia?
Check electrolytes and ECG changes.
What is refeeding syndrome?
- Seen in eating disorder patients
- Characterised by electrolyte imbalance (principally low serum phosphate, potassium, and magnesium) caused by their sudden intracellular movement due to the switch from fat to carbohydrate metabolism and associated increased secretion of insulin
- Defined mainly by low phosphate

- Depression
- BN
- Psychosis (self-starvation might occur if food is believed to be poisoned)
- Eating disorder not otherwise specified
- Body dysmorphic disorder (BDD is a condition characterised by body image distortion (e.g.belief that the nose is misshapen. Deliberate weight loss in BDD would be unusual)
Is there ever watchful waiting for eating disorders?
No
Immediate admission for eating disorder:
Urgent medical treatment is needed in high-risk patients with nutritional decompensation. Markers of this include:
• BMI <13
• weight loss >1kg/week
• purpuric rash
• cold peripheries
• core body temperature <34.5°C
• hypotension (systolic <80mmHg, diastolic <50mmHg)
• bradycardia (<40bpm) with prolonged QT interval on ECG
Management of anorexia (mild):
-Monitor/advice/support for 8 weeks
-Beat charity support
FEATURES: BMI>17, no additional co-morbidity
- Routine referral fo CEDS if failure to respond
Management of anorexia (moderate):
- Routine referral to CEDS
FEATURES: BMI 15-17, no evidence of system failure
Management of anorexia (severe):
- Urgent referral to CEDS (community eating disorder service)
FEATURES: BMI<15, rapid weight loss, evidence in system failure
Management of anorexia for GP presentation?
- Engage and educate (stop laxatives/diuretic use as it does not reduce calorie intake)
- Signpost support (beat charity, MIND, NHS)
- Treat co-morbid psychiatric illness (depression, OCD, substance misuse)
What is the eating disorder questionnaire?
SCOFF questionnaire
- Do you make yourself Sick (induce vomiting) because you feel uncomfortably full?
- Do you worry that you have lost Control over how much you eat?
- Have you recently lost more than One stone (14 lb [6.4 kg]) in a three-month period?
- Do you think you are too Fat, even though others say you are too thin?
- Would you say that Food dominates your life?
One point for every yes answer; a score 2 indicates a likely case of anorexia nervosa or bulimia
nervosa (sensitivity: 100 percent; specificity: 87.5 percent).
Plan for anorexic patients at GP?
- Nutrition and weight restoration (set target weight + make eating plan to gain 0.5-1kg/week)
- CBT-ED, MANTRA or SSCM (or family therapy if less than 18 years)
Endocrine dysfunction in anorexia:
The hypothalamic–pituitary–gonadal axis is affected, causing amenorrhoea in women and impotence in men. Libido is lost in both sexes. If AN begins before puberty, menarche and breast development are delayed or arrested.
Prognosis of anorexia:
After 10 years, 50% recover, 10% die and 40% ongoing problems
Bad prognostic factors for anorexia:
- Very low weight
- Later onset
- Bulimic features
- Longer illness duration
Complications of anorexia:
- Infertility
- Early death
- Osteoporosis
- Cardia arrhythmias and failure
Children management of anorexia

- Young onset (less than 19)
Indications of interpersonal therapy for ED:
- Longer history of illness
- Onset older (later-onset disease)
2nd line treatment of anorexia
- All if 1st line is unacceptable
- Eating-disorder-focussed Focal Psychodynamic Therapy (FPT)
- Adolescent-focussed psychotherapy (AFP)
- Motivational interviewing
1st Line treatment of anorexia
Offer any of these:
1) CBT-ED - 40 weekly sessions (address low self-esteem, perfectionism and control issues)
2) Maudsley Anorexia Nervosa Treatment in Adults (MANTRA) - 20 weekly sessions (focus on what the cause of anorexia is)
3) Specialist Supportive Clinical Management (SSCM) - 20 weekly sessions led by practitioner (explore problems of anorexia, educate on nutrition and eating habits, explore a future beyond anorexia)
Investigations of anorexia
- Height, weight, and BMI.
- Squat test: Ask the patient to squat down and rise to standing without using their arms (difficult with proximal myopathy).
- Essential blood tests
• ESR, TFTs—exclude most organic causes of weightloss, e.g. hyperthyroidism. ESR is normal or low in anorexia.
• FBC, U&E, phosphate, albumin, LFT, creatininekinase, glucose—evaluate nutritional state and risk. - ECG: Bradycardia, arrhythmias, and a prolongedQT interval.
- Other tests as indicated, e.g. DEXA scans (low bonedensity).
What are the different type of psychotherapies for eating disorders?
Psychotherapies
• Motivational interviewing is an important approach when trying to engage ambivalent patients who lack insight into their disorder—or hold positive views of their illness
• Family therapy—rather than simply focusing on the patient, this involves the whole family. Patients with a short history of early onset anorexia (onset before 19 years) show greatest response.
• Interpersonal therapy aims at improving social functioning and interpersonal skills. This is better for patients with later onset or longer duration of illness.
• Cognitive behavioural therapy—addresses control, low self-esteem, and perfectionism

What is PD associated with? (Fx history)
Personality disorder is associated with a family history of personality disorder, as well as a history of depression and alcohol dependency
What childhood temperament is associated with PD?
Children with ‘difficult’ temperaments have greater problems coping as adults, possibly because they find it harder to develop supportive relationships, and are more distressed by negative events. Early attachment difficulties are also associated with personality disorder
Childhood experience and PD?
Personality disorder is associated with insecure attachment and traumatic, neglectful, or chaotic upbringing.Many people experience traumatic childhoods, and it is not understood why most are resilient, whilst others develop a personality disorder or another mental illness(e.g. depression, eating disorders, or schizophrenia).

Poor sleep-wake cycle
What is the signs and symptoms of adolescents with LD?
Difficulty with peers
Inappropriate sexual behaviours
Difficulty transitioning
What is the signs and symptoms of adults with LD?

Needs extra support
What are the investigations for LD?
- Intellectual impairment: WAIS III (Wechsler Adult Intelligence Scale)
- Verbal IQ + Performance IQ = Full scale IQ
- Adaptive and social functioning: ABAS II (Adaptive behaviour assessment system) Clinical Interview (leave plenty of time) - establish presence in childhood Physical examinations (sight and hearing) School reports
What is the management of LD?
- Biopsychosocial MDT (psychiatrist, OT, SALT, specialist nurse, educational support, social support)
General help:
- Choice board
- Scheduling board
- Self-help board
- Communication aids
Medications: Start slow, go slow (treat co-morbid medical and psychiatric problems)
- Melatonin - helps with poor sleep cycles
Psychosocial interventions:

What are the complications of LD?
- Patients with LD have a higher prevalence of psychological symptoms than general population
- Can be difficulty diagnosing other psychological conditions due to language difficulties and atypical presentations
Is LD more prevalent in males than females?
Males
What is the clinical presentation of LD?
Learning disability usually presents in childhood, but may be missed if mild. Abilities can be delayed, reduced ,or absent in: • language • schooling • motor ability • independent living • employment • social ability
Behavioural difficulties may arise, secondary to a combination of communication problems, psychiatric or physical illness, epilepsy, or suboptimal support for individual needs. ‘Behavioural phenotypes’ are commonly recognized behaviours in particular syndromes, e.g. self-harm in Lesch-Nyhan syndrome.
What are the symptoms of a mild LD disorder?
- Language is usually reasonably good, although its development may be delayed.
- Problems may go undiagnosed, although individuals struggle through school or may be labelled with behavioural problems.
- With appropriate support, many people live and work independently.
What are the symptoms or a moderate LD?
- Language and cognitive abilities are less developed.
- Reduced self-care abilities and limited motor skills may necessitate support.
- May need long-term accomodation with their family or in a staff-supported group home.
- Simple practical work should be achievable in supported settings.
What are the symptoms or a severe LD?
- Marked impairment of motor function.
- Little/no speech during early childhood (some may develop during school years).
- Simple tasks can be performed with assistance.
- Likely to require their family home or 24-hour-staffed home.
What are the symptoms or a profound LD?
- Severely limited language, communication, self-care, and mobility.
- Significant associated medical problems.
- Usually require higher levels of support.
What is diagnostic overshadowing?
Diagnostic overshadowing describes the tendency to attribute everything to the learning disability itself. Changes in behaviour, mental state, or ability are dismissed, despite usually indicating physical or mental illness in people without a learning disability.
What are differential diagnosis for LD?
- Autistic spectrum disorders: people with Asperger’s syndrome (autism with normal intelligence) may have significant social deficits, communication difficulties, and difficulties in living independently
- Epilepsy may cause transient cognitive impairment. Very frequent uncontrolled seizures can mimic persistent cognitive impairment.
- Adult brain injury or progressive neurological conditions: learning disabilities are neurodevelopmental disorders, occurring while the brain is still developing. If the patient presents late, it is important to decide whether or not impaired intellect was present before any adult illness.
- Psychiatric: severe and enduring mental illness such as schizophrenia can lead to chronic cognitive impairment, reduced social functioning, and associated speech disorders—mimicking a learning disability. Exclude intellectual impairment prior to the onset of psychiatric symptoms.
- Educational disadvantage/neglect: lacking the opportunity to learn must be distinguished from a learning disability
What are the investigations you can carry out for LD?
- IQ testing
- Functional assessment of skills, strengths and weakness
- Detailed developmental history from parents
- FBC, U&E, LFT, TFT, bone profile—to exclude reversible disturbances.
- Additional blood tests for known LD causes
- Investigations for associated physical illnesses, e.g.EEG for epilepsy
- Genetic testing if appropriate
Treatment steps for LD?
- Prevention
- Education
- Improved antenatal/perinatal care
- Genetic counselling
- Early detection and treatment of reversible causes - Treat physical comorbidity
- Treat psychiatric comorbidity
- Educational support
- Psychological therapy
- Other support

What is dissociative disorder?
Disorders of physical functions under voluntary control and loss of sensation
- dissociation is a process of ‘separating off’ certain memories from normal consciousness
- in contrast to conversion disorder involves psychiatric symptoms e.g. Amnesia, fugue, stupor
- dissociative identity disorder (DID) is the new term for multiple personality disorder as is the most severe form of dissociative disorder
What is conversion disorder?
An internal conflict which is converted into physical manifestations
- typically involves loss of motor or sensory function
- the patient doesn’t consciously feign the symptoms (factitious disorder) or seek material gain (malingering)
- patients may be indifferent to their apparent disorder - la belle indifference - although this has not been backed up by some studies
What is somatisation disorder?
Disorders involving pain or autonomically-controlled sensations
- multiple physical SYMPTOMS present for at least 2 years
- patient refuses to accept reassurance or negative test results
Subtypes of dissociative disorder are?
- Dissociative amnesia: Loss of memory (too great to be explained by ordinary forgetfulness)
- Dissociative fugue: Dissociative amnesia + purposeful travel beyond everyday range (“Travel far and wide”)
- Dissociative stupor: Lack of voluntary movement/normal responses to external stimuli. Evidence of stress from recent events
- Trance and possession disorder: Temporary loss of personal identity and full sense of awareness of surroundings
- Dissociative motor disorders: Loss of ability to move whole/part of limbs. Close resemblance to ataxia, apraxia, akinesia, aphonia, dysarthria, dyskinesia and seizures.
- Dissociative convulsions: Mimic epileptic seizures (tongue biting, bruising from falls and incontinence is rare). Consciousness maintained or replace by a state of stupor or trance
- Dissociative anaesthesia: Areas of anaesthesia do not follow normal dermatomal distribution. May be accompanied by paresthesia.
Risk factors of dissociative disorders:
- Traumatic events
- Intolerable problems
- Disturbed relationships
Signs and symptoms of dissociative disorder:
Onset = acute, specific, dramatic, following sudden stress of conflict
Presentation:

- Fugue (loss of memory and wonder away from home)
- Psychogenic amnesia (loss of all memories, including own identity)
Investigations of dissociative disorder:
1st: Exclude organic cause
- raised prolactin after real seizure
- normal prolactin after dissociative convulsion
2nd: Identify and treat any co-morbid depression
Management of dissociative disorder:
- 75% of people have self-limiting spontaneous recovery
- Supportive therapy:
Encourage return to normal activity
Avoid reinforcing behaviour (providing a wheelchair for dissociative stupor/motor disorder)
Address physical stressors rather than focus on physical manifestations
What is somatisation? ICD-10 definition
- Multiple, recurrent and frequently changing physical symptoms of > 2 years.
- Have complicated history of contact with medical care –> many negative investigations carried out
- Symptoms may be referred to any part or system of the body
- The disorder is chronic and fluctuating –> disruption of social, interpersonal and family behaviour
Is somatisation more common in men or women?
10:1 Female to male
Subtypes of somatisation:
- Undifferentiated somatoform disorder: Multiple varying and persistent complaints of <2 years
- Hypochondrial disorder: Persistent preoccupation with idea of having a serious/progressive physical disorders. Normal sensations interpreted as abnormal or distressing. Co-morbid anxiety and/or depression common. Patient maintains their belief depite being told otherwise (overvalued idea) - Often cancer, pre-occupation with a single problem
- Somatoform autonomic dysfunction: Symptoms presented as if due to physical disorder of system/organ largely or completely under control of the ANS. Objective autonomic arousal (palpitations, sweating, flushing, tremor). Subjective non-specific (fleeting aches/pains, burning sensation, bloating)
- Persistent somatoform pain disorder: Persistent, severe and distressing pain (not otherwise explained). Evidence of emotional conflict of psychological problems
Signs and symptoms of somatisation:
- Multiple recurrent and frequently changing physical symptoms
- History of interactions with medical professionals without outcomes
- Social and occupational impacts
Investigations of somatisation:
- Full history and MSE (with physical examination)
- Exclude organic cause (eg stroke)
- Exclude co-morbid conditions (eg. with HADS for potential depression)
Management of somatisation disorder:
Make sure continuity of care - see by the same doctor each time
1st: Explain and reassure
2nd: CBT
Also treat co-morbid conditions (eg depression)
Definition of somatisation?
This is the unconscious expression of psychological distress through physical symptoms ,e.g. rather than anger, a patient experiences abdominal pain
Management of MUS?
- Assessment - history and examination
- Explain and reassure - Use the Reattribution Model:
• Ensure they feel understood.
• Broaden the agenda from a physical cause to a physical and psychological explanation.
• Make the link between symptoms and psycho-logical factors. - Avoid over-investigation, unnecessary specialist referral or medications
- Emotional support
- Encourage normal function
- Antidepressants - even without depression symptoms
- Treat co-morbid conditions
- CBT
- Graded exercise - helpful in some conditions eg fibromyalgia and CFS
Prognosis of MUS?
Shorter duration of MUS and milder symptoms are linked to better prognosis.

- If weak outcome due to lack of parental engagement, move to 2nd line
2nd: Child individual or group interventions focussed on problem solving and anger management
- Often, affected children do not have the motivation to engage with these well
Remedial educational teaching (for missed school)
Alternative peer activities
Prognosis of conduct disorder:
- 50% develop antisocial personality disorder Poorer prognosis: - Early onset - Family criminal record - Low IQ - Low socio-economic status - Co-morbidities - Poor parenting

- If they last longer than 1 month, consider PTSD
Onset of symptoms within minutes
How does ASD differ from PTSD?
- PTSD is diagnosed based on symptoms in clusters, not in totality
- PTSD has a dissociative sub-type, however, in ASD, depersonalisation and derealisation are symptoms
- PTSD includes non-fear based symptoms (risky behaviour) but ASD does not

- Tachypnoea
- Hypertension
- Partial or complete amnesia may be present
- Depersonalisation
- Derealisation

CBT with trauma focus: offer to all patients with moderate-severe PTSD, presenting > 1 month
Eye movement desensitisation and reprocessing (EDMR): offer if moderate-severe PTSD, >3 months after non-combat relayed event
(patient recalls experience in as much detail as possible in a state of relaxation, whist their eyes are fixed on the therapists finger as it moves from side to side –> aids memory processing)
What is trauma focused CBT?
- Combination of exposure therapy and trauma-focused therapy
- Computerised or face-to-face
NB: immediate post-trauma formal debriefing actually increases risk of PTSD

- Melatonin for sleep difficulties
- Methyphenidate (Ratilin) for attention difficulties
- SSRIs for obsessional behaviours
Symptoms and signs of Autism SD?
- Reciprocal social interaction: Autistic children are not interested in people; they appear aloof, tend to play alone, and lack the ability to ‘read’ emotional states in others. Attachments are impoverished, with-out mutuality or warmth; these children do not turn to parents for comfort. Eye contact may be odd, either avoidant or ‘looking through’ you.
- Communication abnormalities: Expressive speech and comprehension are delayed or minimal. Ideas are taken literally (concrete thinking). Gestures are usually absent (e.g. pointing, waving goodbye). Later, speech may consist of monologues, interminable questions, or echolalia (repeating what has been said), but there is no exchange. Classically ‘I’ and ‘me’ are confused with ‘you’, ‘he’, and ‘she’ (pronominal reversal)
- Restricted behaviours and routine: Autism is characterised by repetitive, stereotyped behaviours and restricted interests—rather than imaginative play. Even small changes in routine (e.g. the wrong spoon) can result in intense tantrums.
Differential diagnosis for Autism SD?
- Deafness causes poor language acquisition.
- Asperger’s syndrome
- Specific language disorder: delayed speech but normal IQ and social ability.
- Learning disability: IQ problems but relatively intact social skills.
- Rare disorders, e.g. childhood schizophrenia, Rett’ss syndrome.
- Neglect can lead to language delay and poor socialization—reversible unless severe
Investigations for Autism SD?
- Hearing tests.
- Speech and language assessment.
- Neuropsychological testing—assess IQ and confirm diagnosis.
Management of Autism SD?
- Support and advice for families, e.g. the National Autistic Society.
- Behaviour therapy —reinforce positive behaviours
- Speech and language therapy.
- Special education.
- Treat comorbid problems (e.g. epilepsy).
- Antipsychotics or mood stabilizers are occasionally used for extreme aggression or hyperactivity.
Prognosis of Autism SD?
Only 1–2% of adults gain full independence, with most needing lifelong support and care. Good prognostic indicators are an IQ over 70 and acquisition of some useful language
What is aspergers?
- An autistic spectrum disorder.
- Male:female = 8:1.
- Poor social skills and restricted interests.
- Normal language and IQ.
- Tendency to literal interpretation of language and difficulty in reading social cues.
- Management: advice, support, routine, social skills training.
- Prognosis is much better than for autism.
What is Tic disorder?
Tics are repetitive, involuntary, and purposeless movements or vocal utterances. They are categorised as simple(e.g. blinking, throat-clearing) or complex (e.g. self-hitting, swearing). Transient simple tics affect 10% of children, and are three times more common in boys.There is often a family history of problems and obsessive–compulsive disorder is commonly comorbid. Stress or stimulant medications usually worsen tics. They recede when the sufferer is concentrating on something else.Tics can be voluntarily suppressed at the cost of internal tension, which is relieved by their expression. Reassurance and stress management are effective treatments but clonidine (adrenergic agonist) or haloperidol(antipsychotic) are also useful.

Symptoms of ADHD?
- Hyperactivity
Children are boisterous with excessive energy. They seem constantly on the move: running, jumping, climb-ing, unable to sit still for any length of time without fidgeting, squirming, or wandering about. They are usually noisy and garrulous.
-Inattention
Children are distractible and unable to concentrate, flitting chaotically between activities and leaving tasks unfinished.
-Associated features.
These children are impulsive and reckless, rarely stopping to consider the consequences of their actions. This can result in risky behaviour, e.g. poor road safety. They tend to be clumsy and accident prone, and may be dis-obedient, although often through impulsivity rather than deliberate naughtiness. Additionally, they are socially disinhibited, paying little attention to normal social conventions; they interrupt others and find it hard to wait their turn. Learning disability and conduct disorder are associated.
Differentials for ADHD?
- Depression/anxiety—both can cause agitation.
- Mania (extremely rare in childhood).
- Conduct disorder
Management of ADHD?
- Family: education on ADHD; advice on parenting and boundaries.
- Behavioural management
- Support for teachers: appropriate schooling placement.
- Family therapy.
- Stimulant medication (e.g. methylphenidate, dexamphetamine). This increases monoamine pathway activity, improving concentration and allowing learning and maturation. Adverse effects include appetite suppression and insomnia. ‘Drug holidays’ (weekends and school holidays) limit growth retardation to 1cm. Stimulant medications are not addictive in ADHD
What is conduct disorder?
Behaviour is persistently antisocial, not merely ‘rebellious’,e.g. bullying, stealing, fighting, fire-setting, truancy, and cruelty to animals or people. In socialized CD the child has a peer group (often sharing in the antisocial behaviour). Children with unsocialized CD are rejected by other children, which often makes them more isolated and hostile.
Differential diagnosis of Conduct disorder?
- Oppositional defiant disorder: a milder form of CD, occurring in children under 10, with provocative, angry, and disobedient behaviour towards adults. No extreme antisocial behaviour is present.
- ADHD
- Depression: some children present with antisocial behaviour.
Management of conduct disorder?
- Family education: the family members need to understand CD and recognize that they may reinforce problems.
- Parent management training: teaches parents to reward good behaviour and deal constructively with negative behaviours.
- Family therapy: the family meets with a skilled therapist to discuss current problems. They are helped to cooperate in problem solving.
- Educational support.
- Anger management for the child.
- Treat comorbid problems, e.g. ADHD.
Prognosis of conduct disoder?
50% develop substance misuse disorder or dissocial personality disorder as adults.

- choking sensation
- pins and needles
- depersonalisation
- shaking
- dizziness/faints

Therapy: Desensitisation approach
(1) : patient identifies goal and constructs hierarchy of feared situations
(2) patient tackles hierarchy from least to most frightening
(3) aim to stay in situation until anxiety subsidised –> challenges existing thoughts
CBT: reduce patient’s expectation of threat, and behaviours that maintain threat-related beliefs
- explore the actual likelihood and impact of the anticipated catastrophe
- test the feared situation and their belief in a catastrophic outcome using behavioural experiments
- improves self confidence of the patient

- if still using heroin –> low-dose methadone
- If wanting to stop heroin completely –> high-dose methadone or buprenorphine
- Offer naloxone to take home with them and training on when/how to use it
Detoxification: (must be committed to stopping)
- Must be on stable OST maintenance before you start detox
- Last 12 weeks as an outpatient
- Inform them they will lose tolerance so if they start again, they should take a lot less
- 1st line: Methadone (liquid) or buprenorphine (sublingual) and offer naloxone to take home with them and training on when/how to use it
- 2nd line: Lofexidine (alpha 2 agonist), indications: rapid detox, mild dependance, preference

- ECG (QTc) for those with methadone
- Check other drug use (urine drug screens)
- CBT (to reduce relapse chance)
- Contingency management (through frequent screening –> less frequent screenings as time goes on) - incentive for -ve drug test results, urinalysis preferred
What is Alzheimer’s?
- Most common form of dementia with steady progression
- APP= amyloid precursor protein
