Q

Depression investigations/diagnosis

A

DSM-5 (diagnostic and statistical manual of mental disorders)
Presence of at least 5 out of 9 defining symptoms for at least 2 weeks or severe enough to impair social, occupational or other important areas of functioning. Classified as mild, mod or severe, determined by both number of symptoms, persistence, presence of other symptoms as well as degree of functional and social impairment
PHQ9 (patient health questionnaire 9) rates severity: 0-4 = none. 5-9 mild. 10-14 mod. Mod severe 20-27. 28+ severe.

Depression categories

A

Subthreshold: between 2-5 symptoms
Mild: >5 symptoms but only result in minor functional impairment
Mod: if symptoms or functional impairments between mild and severe
Severe: Most symptoms and markedly interferes with functioning. Can occur without psychotic symptoms
Dysthymia (persistent subthreshold depression): subthreshold symptoms for more days than not for at least 2 years which is not consequence of partially resolved major depression
Seasonal affective disorder: episodes of depression which recur annually at same time each year with remission in between (usually appearing in winter and remitting in spring)

Q

Depression management (medications)

A

Medications:
Selective serotonin reuptake inhibitor (SSRI): sertraline (tends to have less side effects), citalopram, fluoxetine (start on any drug there is no first line, discuss what’s best for pt and start on low dose and work up)
Serotonin-norepinephrine reuptake inhibitors (SNRIs): venlafaxine, duloxetine
Tricyclic antidepressants TCA: amitriptyline
Monoamine oxidase inhibitors MAOIs: not used much
Consider medications for mod/severe depressions.
Consider drug interactions with other medications and patient preference (side effects disturb sleep etc)
Pt compliance is extremely important: must take OD for effectiveness, impress importance on pt
May feel worse in first week of taking
Can take 2-4 wks to feel benefit
Need to be taken daily ideally for at least 4 wks before dose change
Regularly review esp for suicidal pts
Side effects: usually settle after a few wks

Q

Depression management (psychological interventions)

A

Cognitive behavioural therapy CBT
High intensity therapies: interpersonal therapy (IPT) or behavioural activation
Counseling and short term psychodynamic therapy
Electroconvulsive therapy (ECT)
CBT: help to change the way people think, feel and behave
Problem focused and practical
Can be delivered to individuals, couples, families or groups
ECT: reserved for severe depression if persons life at risk and need urgent treatment
OR mod-severe depression when no other treatment has helped
ECT involved passing electric current through the brain so is always given in hospital under general anaesthetic
Some people have temporary memory problems after ECT
Suicide risk: important to ask and clarify thoughts, plans, intent
Assess would pt need same day admission
If actively suicidal review medications that may worsen this (SSRIs and SNRIs are associated with increased risk of suicidal thinking and self harm particularly <30 years)
Abuse of alcohol or drugs also increases

Q

Acute reaction to stress

A

Acute reaction following an unexpected life crisis; serious accident; sudden bereavement or other traumatic event
Symptoms develop and resolve quickly
Events triggering are usually very severe and acute stress reaction typically occurs after unexpected life crisis
Trigger can include: Assault, serious accident, sudden loss, traumatic events
Difference between this and depression would be large life factor trigger and acute duration of symptoms

Q

Bipolar management

A

primary care:
Referral to mental health team to confirm diagnosis
Refer urgently for mental health assessment if severe mania, severe depression or danger to themselves or others
Assess safeguarding of pt and any defendants - vulnerable to exploitation or violence
Review medications - antidepressants can worsen mania episodes

Secondary care:
1st line oral antipsychotic: haloperidol, olanzapine, quetiapine or risperidone
2nd line: lithium or sodium valproate (caution women at childbearing age) risk of foetal malformations and adverse neurodevelopmental outcomes after any exposure during pregnancy.
During depressive episode: quetiapine alone (mood stabiliser) or fluoxetine with olanzapine or olanzapine alone or lamotrigine alone
Constantly have to take these medications. Review all regularly (unlikely to change doses; more for psychiatrists)

Q

Schizophrenia diagnosis

A

ICD-10 criteria: symptoms present most of time for at least 1 month with one or more of following features:
Hallucinatory voices
Thought echo, thought insertion or withdrawal and thought broadcasting
Delusions of control, influence, passivity, clearly referred to body or limb movements or specific thought, actions or sensations
Persistent delusions of other kinds that are culturally inappropriate and completely impossible, such as religious or political identity, superhuman powers and abilities or being in communication with aliens

Or any two of the following:
Persistent hallucinations in any form, when accompanied by fleeting or half-formed delusions without clear affective content, or by persistent overvalued ideas (similar to preoccupations), or when occurring every day for weeks or months on end.
Breaks or interpolations in the train of thought, resulting in incoherence or irrelevant speech, or neologisms (invented words).

Catatonic behaviour, such as excitement, posturing, or waxy flexibility; negativism; mutism; and stupor.

Negative symptoms, such as marked apathy, reduced speech, and blunting or incongruity of emotional responses, usually resulting in social withdrawal and lowering of social performance; it must be clear that these are not due to depression or to antipsychotic medication.

A significant and consistent change in the overall quality of some aspects of personal behaviour, manifest as loss of interest, aimlessness, idleness, a self-absorbed attitude, and social withdrawal.

Q

Anti-psychotic guidance

A

There is no first-line antipsychotic drug suitable for all people with psychosis, and (bar clozapine) little meaningful difference in efficacy.
• Clozapine is generally offered to people who do not respond adequately to two other antipsychotics and is always initiated and monitored in secondary care.
Response to antipsychotics is variable
Dosage and intervals are decided on case by case basis according to persons response
1st gen: thought to work by blocking dopamine 2 receptors in brain and can cause extrapyramidal symptoms (EPS) and wide range of other adverse effects
2nd gen: act on range of receptors and associated with fewer EPS than 1st gen. Associated with several other important adverse effects: weight gain, glucose intolerance, hyperprolactinaemia
Have significant effects on acetylcholine, histamine, noradrenaline and serotonin pathways! Never quickly remove drugs, always taper off!!

Choice depends on:
Patient preference
Medication history, 
Degree of sedation required, 
Risk of particular adverse effects
Degree of negative symptoms (2nd-generation antipsychotics may be more beneficial).

Q

Extrapyramial symptoms (EPS)

A

Caused by antipsychotics
Dystonic reactions (abnormal movement of face and body) and pseudoparkinsonism (tremor, bradycardia, rigidity) these can be alleviated by antimuscarinic drugs like procyclidine (not routinely prescribed)
Akathisia (motor restlessness): improved by reducing dosage
Tardive dyskinesia: rhythmic involuntary movements, usually lip-smacking, tongue rotating, although can affect limbs and trunk.
Late onset symptoms that can worsen on treatment withdrawal!

Q

Drug overdose and investigations

A

Medical emergency
Common causes: paracetamol, alcohol, salicylate (commonly aspirin), opioid overdose
Caustic agents: agents with potential to cause tissue destruction, alkaline substances cause liquefactive necrosis, resulting in deep tissue penetration

Investigations:
Bloods: paracetamol, salicylate levels, blood glucose
ABG
U+Es
LFTs and eGFR
Urine sample
Gastric aspirate or vomitus

Q

Drug overdose management

A

ABCDE: Eyes (dilated pupils indicate tricyclics, cocaine, amphetamine; pinpoint pupils indicate opiates; nystagmus indicates alcohol, benzodiazepines, phenytoin) Breath (bitter almond smell of cyanide indicates alcohol or organic solvents) burns around mouth (corrosive substances like paraquat, glue) hyperventilation (salicylates) needle marks (recreational drug abuse)
Identify substance: if pt is unconscious, third party evidence of what has been taken. Time of ingestion, associated alcohol consumption, past and current medical history (esp if renal or liver disease), symptoms noticed since poisoning (vomiting may have removed some substance already, hematemesis caused by iron overdose, salicylates, alcohol)
Elimination: activated charcoal (decontamination) decreases absorption within 1 hr of digestion (preferred), antidote administration, gastric lavage (no longer recommended due to aspiration risk; only indicated in life threatening amount ingested within previous hr and poison cannot be removed via other methods. May be useful for drugs such as lithium and iron which aren’t charcoal absorbed), dialysis (peritoneal, haemodialysis), diuresis (alkaline, acid change urinary pH to increase substance excretion in urine) whole bowel irrigation (when substance would not be absorbed by activated charcoal)
Specific and general treatment of pt condition
Period of observation
Psychiatric assessment

Q

Charcoal for drug treatment

A

Single-dose activated charcoal is the preferred method of decontamination in many cases.
Patients should have had a significant overdose, be co-operative, without impairment of consciousness and not thought to be likely to fit imminently.
Ideally it is used in a 10:1 ratio with the ingested drug - the usual dose is 50 g for an adult (children: 1 g/kg).
It may be repeated in one hour if necessary (oral, nasogastric tube). Its large surface area adsorbs many drugs but has its limitations.
It may not be be effective if given after the first hour or in cases of poisoning with iron, lithium, boric acid, cyanide, ethanol, ethylene glycol, methanol, malathion, DDT, carbamate, hydrocarbon or strong acids or alkalis.

Mostly affects children (1%); 2-8% prevalence among siblings
More boys diagnosed than girls
More heritable of childhood onset neuropsychiatric disorders (90%)
70% those diagnosed have other impaired psychological functioning such as ADHD and Anxiety disorders
Can be diagnosed in young people and adults if meet criteria (ICD-10 and DSM-5)
DSM-5 refers to autism spectrum disorder as a single condition with different levels of symptom severity in 2 core domains:
•1) deficits in social communication and social interaction and
•2) restricted repetitive behaviours (RRBs), interests, and activities and sensory anomalies
Learning disability: IQ <70 occurs in approx 50% people with autism
Others may not have learning disability or learning delay but just need special educational needs (SEN)

Presence of anticipatory anxiety

95
Q

Top ten phobias

A

Arachnophobia: The fear of spiders. This phobia tends to affect women more than men.
Ophidiophobia: The fear of snakes.
Acrophobia: The fear of heights.
Agoraphobia: The fear of situations in which escape is difficult. This may include crowded areas, open spaces, or situations that are likely to trigger a panic attack. People will begin avoiding these trigger events, sometimes to the point that they cease leaving their home. Approximately one third of people with panic disorder develop agoraphobia.
Cynophobia: The fear of dogs. This phobia is often associated with specific personal experiences, such as being bitten by a dog during childhood.
Astraphobia: The fear of thunder and lightning.
Trypanophobia: The fear of injections. Like many phobias, this fear often goes untreated because people avoid the triggering object and situation.
Social Phobias: The fear of social situations. In many cases, these phobias can become so severe that people avoid events, places, and people that are likely to trigger an anxiety attack.
Pteromerhanophobia: The fear of flying. Often treated using exposure therapy, in which the client is gradually and progressively introduced to flying. [Denis Bergcamp]
Mysophobia: The fear of germs or dirt. May be related to obsessive-compulsive disorder.

105
Q

Panic disorder diagnostic criteria

A

Panic attacks must be associated with:
>1 month duration of subsequent and persisting anxiety about recurrence of attack and consequences of attack
Or significant behavioural changes associated with attacks
A fundamental characteristic of panic disorder is the presence of recurring, unforeseen panic attacks followed by at least 1 month of persistent worry about having another panic attack and concern about the consequences of a panic attack, or a significant change in behaviour related to the attacks.
At least 2 unexpected panic attacks are necessary for diagnosis.
Attacks should not be accounted for by the use of a substance, a general medical condition or another psychological problem.

106

108
Q

PTSD

A

Traumatic event (usually major threat to physical, emotional or psychological safety of themselves, loved ones etc) causing the person to develop PTSD as a result of overwhelmed coping and defence mechanisms
Can be experienced directly, witnessed in person, learning of traumatic events occurring to someone close, or experiencing repeated or extreme exposure to details of traumatic events (common in first responders, emergency personnel, police)
25-30% people experiencing a traumatic event develop PTSD
Thought to result from the HPA axis and noradrenaline is main transmitter involved
Reconsolidation (the way the brain reconstructs memories and associated emotional responses) appears to be important in PTSD

109
Q

PTSD presentation

A

Re-experiencing
Vivid, distressing memories of the event or flashbacks, known as intrusive symptoms. (most common)
PTSD cases often have nightmares related to the trauma that affect their sleep.
2.Avoidance or Rumination
Avoidance of trauma-related reminders or general social contact.
People with PTSD often try to push memories of the event out of their mind and avoid thinking or talking about it in detail.
They may also reflect excessively on questions that prevent them from coming to terms with the event - for example, why it happened to them, how it could have been prevented, or how they could take revenge.
3.Hyperarousal or Emotional numbing
Alterations in arousal and reactivity: irritable behaviour and angry outbursts - reckless or self destructive behaviour – hypervigilance - exaggerated startle response - problems with concentration etc

110
Q

PTSD time of presentation

A

Often develop immediately following event
But in 15% cases onset is delayed
May not present for months, years despite experiencing considerable distress
Comorbidities often common with prolonged PTSD suffering (depression, anxiety, substance abuse)

Management:
Treatable even for those presenting years later
Multidimensional approach
Psychological therapies: trauma focused CBT (TF-CBT), eye movement and reprocessing (EMDR) and stress management
Education and supportive measures (emotional hygiene; positive thoughts, self appreciation, less rumination on bad thoughts)
Medications: paroxetine, mirtazapine, clonidine

Associated disease:
Erotomania
Occasionally associated with other delusions of grandiose, jealous or somatic
Epilepsy or frontal lobe lesions

Management:
Manage any secondary associated disorder
Successful management is difficult: psychotherapies and antipsychotics
Pimozide, risperidone and ECT if severe may have varying degrees of success

124
Q

Substance addiction/dependence

A

Alcohol
Drugs
Tobacco
Key points:
Higher incidences in areas of social deprivation
UK has one of the highest morbidity and mortality rates
Heroin most common main problem drug in adults, cannabis and alcohol main problem drugs under age 18
Drug misusers may have multiple social and medical problems (increasing mortality)
Drug misusers are at high risk of: hep C, HIV and hep B

125
Q

Substance dependence investigations

A

Good initial assessment is essential: via MDT, try to engage pt in their own care
Gain confirmation of drug history
Examine patient for needle marks or signs of withdrawals
Urine analysis for drugs testing
Bloods: Hep B, C, HIV screening
Assess risks to children, risk to themselves or to others
Full physical health checks
Refer for full psychiatric health checks

126
Q

Substance dependence management

A

Needs assessed in terms of health, social functioning and criminal involvement

Draw up individual healthcare plan and review regularly

Named person should manage and deliver individuals care (key worker)
If detoxification or substitute prescribing needed refer to local specialist community drug services and ensure care plan is shared between facilities

Regular drug testing to monitor compliance and treatment outcome

Therapies: IPT, CBT high intensity, counselling and supportive care (AA groups etc)
If cannabis, hallucinogen and stimulant abuse (including cocaine) then psychological interventions are the main treatment
For opioid, alcohol and polydrug misuse psychological interventions can be used in conjunction with drug treatment

Medical interventions:
Methadone and buprenorphine are both effective as maintenance treatment (recommended NICE)
Oral methadone maintenance associated with reduction of drug related behaviours with high risk HIV transmission but less effect on reduced sexual risk taking
Combined buprenorphine and naloxone (Suboxone) doesn’t interfere with therapeutic effect of buprenorphine

Before prescribing: need to see evidence that patients are drug dependent and motivated to change. Do not prescribe too rapid increase in dose (overdose)
Consider Vaccinating against hep A, B, C and HIV, TB and tetanus

127
Q

Common phenomenon 
For example, headaches caused by stress
Other symptoms include:
Chest pains
Fatigue
Dizziness
Back pain
Nausea
Diarrhoea
128
Q

Somatoform disorders

A

Somatoform disorders arise at the extreme ends of the scale of somatisation. Physical symptoms persist long term or are severe but no physical disease can fully explain the symptoms
Relatively rare, hypochondriasis and body dysmorphic disorder are slightly more common
Thought to have some genetic as well as social and environmental factors which all contribute
Common in people who abuse drugs and alcohol so these may also both cause and contribute to the disorders themselves as well as sufferers are more likely to misuse substances
Types:
Hypochondriasis
Conversion disorder
Pain disorder
Body dysmorphic disorder
Somatoform disorder not otherwise specified

129
Q

Somatoform disorders presentation

A

Fearing minor symptoms may be due to serious disease
Eg minor headache may be caused by brain tumour or mild rash is sign of skin cancer
Even normal bodily functions such as stomach noises may be thought of as illnesses
People with disorder have many fears and spend a lot of time thinking about their symptoms
This disorder is similar to somatisation disorder but the difference being hypochondirasis pts may accept the symptoms are minor but believe or fear they’re caused by serious disease.
Doctoral reassurance usually does not help as they often fear they just haven’t found the diagnosis

131
Q

Conversion disorder

A

Condition where person has symptoms suggesting serious disease of brain or nerves e.g. loss of vision, deafness, weakness, paralysis or numbness of arms or legs

Some people experience repeated episodes from time to time

132
Q

Treat and screen for any other mental health disorders which may or may not be present
CBT therapy and other psychiatric interventions may help pt to understand their symptoms and develop appropriate coping mechanisms to prevent these effects
Medications for underlying anxiety or depression if present and needed but not often related to these disorders

134
Q

Alcohol dependence

A

Alcohol abuse: consumption of alcohol at a level sufficient to cause physical, psychiatric and/or social harm
Binge drinking: drinking over twice the recommended level of alcohol per day (>8 units male />6 units females
Harmful alcohol use: drinking above safe levels with evidence of alcohol-related problems (>50 units/wk males and >35 females)
Recommended unit intake per wk for both sexes is 14 units/wk
Social learning theory suggests that drinking behaviour is modelled on imitation of relatives or friends.
Operant condition states positive or negative reinforcements from effects of drinking will either perpetuate or deter drinking habits
Males have increased risk of alcohol abuse and increased metabolism of alcohol allowing consumption of higher quantities
Younger adults are more prone to alcohol abuse
Higher risk of dependency with relatives also affected
Premorbid antisocial behaviour has been found to predict alcoholism
Risk of alcoholism decreases in those who show facial flushing with alcohol as this indicates they metabolise more slowly so less likely (more common in east asian populations)

135
Q

Alcohol dependence pathophysiology

A

Affects neurotransmitter GABA systems causing anxiolytic and sedative effects
Pleasure effects from mediation via dopaminergic pathway
Repeated excessive alcohol ingestion sensitises this pathways leading to development of dependence on alcohol
Long-term exposure can cause adaptive changes in neurotransmitters (dow regulation of inhibitory neuronal GABA, up regulation of excitatory glutamate receptors causing hyperexcitability when alcohol is withdrawn)
Pt with alcohol use disorders often experience craving linked to dopaminergic, serotonergic and opioid systems that mediate positive reinforcement and to GABA, glutamatergic and noradrenergic systems that mediate withdrawal

136
Q

Tobacco dependence and immediate effects

A

Smoking increases risk of cardiac disease, lung disease, cancers and many other health problems
Nicotine is addictive substance present in tobacco
Remains leading cause of preventable disease and death globally
2 out of 3 long term smokers will die prematurely of disorders caused by smoking
Immediate nicotine effects:
Activates pleasure centre in brain
Increases energy, concentration
Decreases appetite
Once addicted, will cause relaxation feeling from relieving nicotine withdrawal
Overdosing: nausea, vomiting, diarhoea, sweating and weakness (green tobacco sickness)

152

153
Q

Smoking cessations

A

Smoking cessation clinics: talk about the cost of smoking, reasons to quit healthwise, social wise (increase activity and longevity or seeing family etc)

Treatment of symptoms of withdrawal via nicotine patches, routine hygiene (change routine to avoid smoking triggers eg coffee in the morning if they always smoke after having a coffee, have no smoking around them, engage in rewarding activities smoke free to encourage good feelings)

Withdrawal symptoms: nausea, irritability, lack of concentration, restlessness, tremor, sweating, dizziness, headaches, abdominal pains, disrupted sleep (tend to be most intense within first 2-3 days then subside within 2-4 weeks)

Pts quitting may gain weight, food will taste and smell better, exercise helps prevent weight gain and may reduce nicotine cravings

Drinking water recommended along with other strategies for oral cravings: toothpicks, chewing on straw or carrot sticks etc or nicotine gum to help delay weight gain

Temporary cough may develop as lungs begin to heal themselves

Nicotine replacement therapy:
Variety of formulations: patch, gum, lozenge, inhaler, nasal spray
All provide nicotine to brain without cigarette quick hit feeling
Speed of drug reaching the brain increases addictive potential therefore very unlikely to become addicted to replacement therapies

Cautions: jaw disorders cannot chew gum, skin sensitivity should not use patch, may be harmful in pregnancy, those with recent MI or blood vessel disorders should discuss with dr before going on one of these products

Bupropion or nortriptyline: antidepressant helps with smoking cessation if used in combo with nicotine replacement.

Varenicline: lessens cravings and withdrawal symptoms works by blocking nicotinic receptors and stopping nicotine attaching to receptors so they find it less rewarding

154

The enduring pattern is inflexible and pervasive across a broad range of personal and social situations
The enduring pattern leads to clinically significant distress or impairment in social, occupational, or other important areas of functioning.
The pattern is stable and of long duration, and its onset can be traced back at least to adolescence or early adulthood.
The enduring pattern is not better accounted for as a manifestation or consequence of another mental disorder.
The enduring pattern is not due to the direct physiological effects of a substance (e.g., a drug abuse, a medication) or a general medical condition (e.g., head trauma).
