Subtypes of delusions
delusional disorders
A
grandiose
persecutory
Erotomania
2
Q

A
The presence of delusion (of a famous person being in love with them) with the absence of other psychotic symptoms
3

Hold ‘odd’ beliefs and display bizarre behaviours but do not hold their beliefs with delusional conviction
4

7
Q
Alcohol withdrawal - mechanism, features and management
A
Mechanism:
- chronic alcohol consumption enhances GABA mediated inhibition in the CNS (similar to benzodiazepines) and inhibits NMDA-type glutamate receptors
- alcohol withdrawal is thought to be lead to the opposite (decreased inhibitory GABA and increased NMDA glutamate transmission)
Features:
- symptoms start at 6-12 hours: tremor, sweating, tachycardia, anxiety
- peak incidence of seizures at 36 hours
- peak incidence of delirium tremens is at 48-72 hours: coarse tremor, confusion, delusions, auditory and visual hallucinations, fever, tachycardia
Management
- patients with a history of complex withdrawals from alcohol (i.e. delirium tremens, seizures, blackouts) should be admitted to hospital for monitoring until withdrawals stabilised
- first-line: benzodiazepines e.g. chlordiazepoxide. Lorazepam may be preferable in patients with hepatic failure. Typically given as part of a reducing dose protocol
- carbamazepine also effective in treatment of alcohol withdrawal
- phenytoin is said not to be as effective in the treatment of alcohol withdrawal seizures

Q
Common features of PTSD

9
Q
Post-traumatic stress disorder - features and management
A
Features:
- re-experiencing: flashbacks, nightmares, repetitive and distressing intrusive images

- emotional numbing - lack of ability to experience feelings, feeling detached
from other people:

Management:
- following a traumatic event single-session interventions (often referred to as debriefing) are not recommended
- watchful waiting may be used for mild symptoms lasting less than 4 weeks
- military personnel have access to treatment provided by the armed forces
- trauma-focused cognitive behavioural therapy (CBT) or eye movement desensitisation and reprocessing (EMDR) therapy may be used in more severe cases
- drug treatments for PTSD should not be used as a routine first-line treatment for adults. If drug treatment is used then venlafaxine or a selective serotonin reuptake inhibitor (SSRI), such as sertraline should be tried. In severe cases, NICE recommends that risperidone may be used

NICE suggest a step-wise approach:
step 1: education about GAD + active monitoring
step 2: low intensity psychological interventions (individual non-facilitated self-help or individual guided self-help or psychoeducational groups)
step 3: high intensity psychological interventions (cognitive behavioural therapy or applied relaxation) or drug treatment.
step 4: highly specialist input e.g. Multi agency teams
- Drug treatment
NICE suggest SERTRALINE should be considered the first-line SSRI
interestingly for patients under the age of 30 years NICE recommend you warn patients of the increased risk of suicidal thinking and self-harm. Weekly follow-up is recommended for the first month
63
Management of panic disorder?
A stepwise approach:
step 1: recognition and diagnosis

NICE recommend either cognitive behavioural therapy or drug treatment
SSRIs are first-line. If contraindicated or no response after 12 weeks then imipramine or clomipramine (TCA) should be offered
64
What needs to be considered before a diagnosis of psychotic disorder?
Organic causes must be considered and excluded before the psychosis can be attributed to a primary psychotic disorder.
A CT head scan should be considered in elderly patients with new sudden onset psychosis to rule out an organic cause for their presentation

The presence of psychotic symptoms and significant functional impairment - mania
66

71
What is the management of bipolar?
- psychological interventions specifically designed for bipolar disorder may be helpful
- LITHIUM remains the mood stabilizer of choice. An alternative is valproate
- management of mania: consider STOPPING antidepressant if the patient takes one; ANTIPSYCHOTIC THERAPY e.g. olanzapine or haloperidol
- management of depression: talking therapies (see above); FLUOXETINE is the antidepressant of choice
- address co-morbidities - there is a 2-3 times increased risk of diabetes, cardiovascular disease and COPD
72
What is the management of schizophrenia?

An eating disorder
characterised by episodes of uncontrolled consumption (binging) followed by purgative behaviours (which incise inducing vomiting , taking laxatives or diuretics, or intensely exercising)
88
Define anorexia nervosa
Fasting which is defined as restricting or ceasing eating
89
DSM 5 diagnostic criteria for a diagnosis of bulimia nervosa
- recurrent episodes of binge eating (eating an amount of food that is definitely larger than most people would eat during a similar period of time and circumstances)
- a sense of LACK OF CONTROL over eating during the episode
- recurrent inappropriate compensatory behaviour in order to prevent weight gain, such as self-induced vomiting, misuse of laxatives, diuretics, or other medications, fasting, or excessive exercise.
- the binge eating and compensatory behaviours both occur, on average, at least once a week for three months.
- self-evaluation is unduly influenced by body shape and weight.
- the disturbance does not occur exclusively during episodes of anorexia nervosa.
90
Management of bulimia nervosa
- referral for specialist care is appropriate in all cases
- NICE recommend bulimia-nervosa-focused guided SELF - HELP for adults
If bulimia-nervosa-focused guided self-help is unacceptable, contraindicated, or ineffective after 4 weeks of treatment, NICE recommend that we consider individual eating-disorder-focused cognitive behavioural therapy (CBT-ED)
- children should be offered bulimia-nervosa-focused FAMILY THERAPY (FT-BN)
- pharmacological treatments have a limited role - a trial of high-dose FLUOXETINE is currently licensed for bulimia but long-term data is lacking

100
When is lithium used?
Most commonly prophylactically in bipolar disorder
| Also used as an adjunct in refractory depression
101
What electrolyte disturbance may be seen in bulimia nervosa?
The low chloride suggests the cause of this metabolic alkalosis is loss of hydrochloric acid from the stomach (through vomiting). Severe vomiting would also account for the hypokalaemia shown on ECG.
This patient's ECG shows features of hypokalaemia. This is likely the cause of the palpitations.
102

hypOnatraemia
103

104
What is aripiprazole?
Antipsychotic usually used in the treatment of schizophrenia and the manic phase of bipolar disorder
105
What would differentiate a psychosis from an obsessive-compulsive disorder?
Obsessive-compulsive disorder can be differentiated from psychosis by the level of INSIGHT into their actions
- In OCD the patients normally have a good level of insight into their condition and understand that if they did not perform the acts their obsessive though would not come true. However, they still get the urge to perform them anyway, just to put their mind at ease.
- E.g. if someone think that if they didn't perform certain acts their obsessions wouldn't come true.

- SAD should be treated the same way as depression
- Psychological therapies and follow up with the patient in 2 weeks to ensure that there has been no deterioration.
- Following this an SSRI can be given if needed.
- You should NOT give the patient sleeping tablets as this can make the symptoms worse
110
When should you stop an antidepressant?
If a patient makes a good response to antidepressant therapy they should continue on treatment for at least 6 MONTHS after remission as this reduces the risk of relapse.
111
