Q

Thoughts flow and form

A

Flow
o Amount and speed of thoughts.

Q

delusion: themes, content

A

o Themes of delusions
 e.g. disease, nihilism, poverty, sin, guilt typical in depression
 e.g. control, persecution, reference, religion, love typical in schizophrenia
 e.g. grandiosity, persecution, religion typical in mania
 Reference: innocuous events hold high significance. Two red cars sat at the traffic light which means the FBI are following me.
o Content of delusions
 the specific content is culturally defined
 a persecutor is often recognisable to society/culture as a danger/threat
• e.g. IRA, mafia, MI5, KGB, CIA, devil, evil spirits
 control is by ghosts / spirits in the past, but also now by XRay / radio transmitters
 feared disease: plague syphilis cancer AIDS
o Delusions - Origin
 Are often attempts to explain anomalous experiences e.g. hallucinations, passivity experiences, depression i.e. secondary delusions
 ”My thoughts do not see to be my own. They feel like they are coming from outside of me” is description of inner (abnormal) experience NOT a delusion.
 “they are being transmitted by the Mafia” is an explanatory delusion
 Intensity of certain thoughts can be challenged by asking “what would you say to someone if they were to say this wasn’t true”

o Auditory
 second person voices which directly address the patient
 third person voices which discuss the patient or provide a running commentary on his actions
 thought echo: the patient experiences his own thoughts spoken or repeated out loud
o Olfactory.

Q

SSRI examples and mechanism

A
  • Examples: Escitalopram, Sertraline, Fluoxetine, Paroxetine & Citalopram
  • Mechanism: Block specifically serotonin re-uptake from the synapatic cleft. The actual anti depressant effects are thought to be mediated by neuro – adaptive processes that reduce the amount of inhibitory controls of serotonin release.

Q

Tricyclics (TCA) examples and mechanism

A
  • Examples: Amitryptiline, Imipramine, Dosulepin, Norytrptiline, Lofepramine, Clomipramine.
  • Mechanism: Primarily block the reuptake of noradrenaline and serotonin from the synapse by blocking their transporters.
  • Also antagonize dopamine, histamine and muscarinic acetylcholine receptors, which is responsible for their side effect profile.

Q

Atypical anti-depressant drugs: Noradrenaline and serotonin specific antidepressant (NASSA) example and mechanism and side effects

A
  • Example: Mirtazapine.
  • Mechanism (mixed receptor effects): It is a noradrenergic and specific serotonergic antidepressant (NaSSA) that acts by antagonizing the adrenergic alpha2-autoreceptors and alpha2-heteroreceptors as well as by blocking 5-HT2 and 5-HT3 receptors.

Q

Monoamine oxidase inhibitors (MAOI) examples and mechanism and S/E

A

Examples:
o Reversible: Moclobemide.
o Non reversible: Phenelzine.
• Mechanism: block monoamine oxidase (MA0-A and B) which prevents the breakdown of serotonin and noradrenaline amongst other neurotransmitters. Additionally helps increase neurotransmitter levels

o Interacts with TCA and SSRI, so patient needs to be off of them for several weeks before starting as risk of hypertensive crisis.
o Requires dietary restriction if non reversible antagonist is used as dietary tyramine breakdown is prevented. Need to avoid foods like cheese, red wine and soy.

Q

Bipolar maintenance/prophlaxis

A

1) Lithium: may block phosphatidylinositol pathway (second messenger system) or inhibit Glycogen Synthase Kinase 3β or modulate NO signalling
- 12 hour
- therapeutic levels (0.4-1mmol/l)
- Toxic (>1.5 mmol/l)

CBT and psychoeducation

2nd line:
•Anti convulsants: Lamotragine (primarily depressed), Valporate (hypomanic/manic), Carbamazepine
o Mode of action: very unclear, perhaps potentiate GABA transmission and therefore block overactive pathways (kindling model of bipolar disorder)
o Side effects:
 Valproate & carbamazepine: drowsiness, ataxia, cardiovascular effects, induces liver enzymes
 Valproate: teratogenicity (neural tube defects)
 Lamotrigine: very small risk of Stevens-Johnson syndrome

• Anti-psychotics: usually atypical e.g. Quetiapine, Aripiprazole, Olanzapine, Lurasidone
o Mode of action: Dopamine antagonism + 5-HT antagonism
o Side effects:
 sedation, weight gain, metabolic syndrome
 extra-pyramidal side-effects (Aripiprazole)

Q

Anorexia Nervosa signs/symptoms

A

refusal to maintain body weight at or above 85 % of the expected range for weight and height (BMI 17.5 or below versus 20-25)
• Self-induced weight loss: strict dieting, vomiting, excessive exercise and medication e.g. laxatives to help them loose weight
• Intense fear of weight gain in spite of being underweight; disturbance of body image with abnormal perception of body size/shape; denial of the seriousness of the low weight; amenorrhoea; self-evaluation overly reliant on weight.
• However, some patients do not experience amenorrhoea even at very low body weights.
• Shopping and food preparation can become very time consuming with prolonged studying of the calorie content of food and weighing and measuring portion sizes.
• There may be an obsession with weighing themselves several times a day or a complete avoidance of knowing their weight.

Q

Physical Complications: signs/symptoms of AN

A
  • Electrolyte disturbances: hypokalaemia or hyponatraemia secondary to behaviours such as self-induced vomiting, excess fluid intake, laxative or diuretic misuse or severe malnutrition
  • Cardiac disturbances: low heart rate, low blood pressure, prolonged Qtc interval, arrhythmias, cardiac arrest.
  • Dental problems: dental caries can be severe in patients who induce vomiting and who consume large amounts of acidic or sugary foods; enlarged parotid glands.
  • Gastro-intestinal: abdominal discomfort, indigestion and bloating are common; oesophageal or gastric tears or rupture secondary to bingeing and vomiting, may be life threatening; constipation due to poor intake or stopping laxatives; diarrhoea and incontinence with laxative abuse; delayed gastric emptying in starvation.
  • Oedema and Dehydration: vomiting/laxatives/diuretics can cause dehydration then rebound water retention; oedema can greatly increase weight causing alarm and increased efforts to restrict; poor protein intake can also contribute to oedema.
  • Neurological: vitamin/mineral/potassium deficiencies can contribute to peripheral paraesthesia, tetany or seizures; brains scans show reduced grey matter and enlarged ventricular spaces.
  • Renal: renal damage secondary to chronic hypokalaemia; organ breakdown as body “eats” itself to obtain calories.
  • Endocrine: loss of body fat causes amenorrhoea as ovaries shut down to reduce fertility in absence of reliable food supply; not a reliable contraceptive; hypothalamus impaired; reduced body temperature; abnormal thyroid function tests.
  • Hepatic: raised LFTs as liver is broken down in starvation to provide energy; can lead to liver failure.
  • Dermatological: dry skin; hypercarotenaemia (too much carrots), lanugo hair; poor peripheral circulation (cold and blue); hair loss
  • Musculoskeletal: muscle wasting; weakness; osteopenia or osteoporosis; calluses on back of hand (Russell’s sign) from induced vomiting.
  • Haematological: low WBC common; reduced ability to fight infection; anaemia (iron, B12 deficiency); bone marrow suppression; thrombocytopaenia.

Refeeding syndrome

A

• potentially fatal shifts in fluids and electrolytes in malnourished patients undergoing rapid re-feeding. These shifts result from hormonal and metabolic changes, and may cause serious complications.
• Re-feeding syndrome can cause cardiac abnormalities, delirium, respiratory failure, status epilepticus, and suppression of the haematological system.
• The hallmark feature of re-feeding syndrome is hypophosphataemia. However, the syndrome is complex and may also feature hypokalaemia, hypomagnesaemia, abnormal fluid and sodium balance, changes in fat, glucose and protein, and thiamine deficiency.
Re-feeding oedema can be marked, occasionally leading to weight gain of up to 1kg per day
• Diuretics should be used with extreme caution, as they may precipitate further loss of potassium and cardiac arrest.
• Acute gastric dilation is a rare, but potentially lethal, complication of re-feeding. It presents with vomiting, and abdominal pain and distension. If recognised early, it responds to nasogastric aspiration and intravenous feeding.
• prevent by frequent blood monitoring and slow pace of initial refeeding

95
Q

Schizophrenia

A

• Common chronic relapsing condition often presenting in early adulthood with psychotic symptoms, disorganisation symptoms, negative symptoms and cognitive impairment

96
Q

Schizophrenia Aetiology

A

• Susceptibility genes (need environmental triggers): high risk for bipolar
• Best considered a genetically determined neurodevelopmental vulnerability later triggered by environmental stressors
• Neurochemical changes
o Changes in dopamine signalling within the brain, with this being confirmed by the fact that anti psychotics target dopamine receptors.
o Subcortical Dopamine hyperactivity leads to psychosis
o Mesocortical Dopamine hypoactivity leads to negative and cognitive symptoms
o Serotonin receptors also now thought to be significant
o Glutamate receptors (increasing evidence)
• Neurodevelopmental changes - enlarged ventricles, thinner cortices, reduced frontal lobe volume and frontal lobe grey matter (lack of dendrite growth

97
Q

Schizophrenia Risk factors

A

Drug use - heavy regular cannabis use
o Drugs which release Dopamine in the brain (e.g. amphetamine) or D2 receptor agonists (apomorphine) produce a psychotic state.
• Urban dwelling - up to 2-fold increase in risk
• Social adversity or deprivation
• Positive Family History – Biggest known risk factor
• Birth Complications
• Risk of schizophrenia increased by 50% by childhood viral CNS infection e.g. Mumps

98
Q

Schizophrenia diagnostic criteria

A

• At least one of the following (1)
o Thought echo, thought insertion or withdrawal, or thought broadcasting.
o Delusions of control, influence or passivity, clearly referred to body or limb movements or specific thoughts, actions, or sensations; delusional perception.
o Hallucinatory voices giving a running commentary on the patient’s behaviour, or discussing him between themselves, or other types of hallucinatory voices coming from some part of the body.
o Persistent delusions of other kinds that are culturally inappropriate and completely impossible (e.g. being able to control the weather, or being in communication with aliens from another world).
• (2) or at least two of the following:
o e) Persistent hallucinations in any modality, when occurring every day for at least one month, when accompanied by delusions (which may be fleeting or half-formed) without clear affective content, or when accompanied by persistent over-valued ideas.
o f) Neologisms, breaks or interpolations in the train of thought, resulting in incoherence or irrelevant speech.
o g) Catatonic behaviour, such as excitement, posturing or waxy flexibility, negativism, mutism and stupor.
o h) “Negative” symptoms such as marked apathy, paucity of speech, and blunting or incongruity of emotional responses (it must be clear that these are not due to depression or to neuroleptic medication).

o Difficulties in controlling substance use (craving)
o A physiological withdrawal state (some drugs have a psychological dependence)
o Evidence of tolerance: higher amounts to get the same effect
o Preoccupation with substance misuse: most of their thoughts are about it (Neglect of alternative pleasures)
o Persistent use despite harmful consequence

165
Q

Opiate misuse aetiology

A

Mesolimbic pathway is a motivating signal and incentivises behaviour (dopamine release)
o Due to repeated dopamine release, dopamine receptors down regulate. Threshold for rewards during abstinence is thus increased. Normal experiences don’t evoke adequate reward response. These changes persist despite prolonged abstinence from substance abuse. D2 receptors are decreased in addiction

Addictive drugs provide a potent signal that disrupts normal dopamine-related learning in the PFC
o Prefrontal cortex puts the brakes on the reward pathway
o Prefrontal cortex matures late and is vulnerable whilst developing (reduced in addition)

Stress
o Acute stress triggers release of dopamine in the neural reward pathway.
o Chronic stress leads to dampening of dopaminerigc activity through down regulation of D receptors.
o This reduces sensitivity to normal rewards
o Encourages exposure to highly rewarding behaviours
o Rapid increase in stress can motivate drug seeking in dependent individuals.

Relapse prevention OF ALCOHOL misuse

A

CBT and motivational enhancement therapy

Pharmacological

  • disulfram (antebuse): inhibits acetaldehyde dehydrogenase
  • acamprosate (acts on glutamate and GABA central systems) - reduces cravings
  • Naltrexone (1st line relapse: opioid antagonist and reduces reward from alcohol)

Q

Dementia

A

syndrome due to disease of the brain, usually of a chronic or progressive nature, in which there is disturbance of multiple higher cortical functions, including memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgement. Consciousness is not clouded. The impairments of cognitive function are commonly accompanied, and occasionally preceded, by deterioration in emotional control, social behaviour, or motivation

Q
Declarative Memory 
Procedural Memory 
Implicit memory 
Explicit memory 
“Semantic memory 
Episodic memory
A

• Declarative Memory – knowing that -know that Paris is the capital of France
• Procedural Memory –knowing how to – e.g. ride a bike
• Implicit memory – revealed when performance on a task is facilitated in the absence of conscious recollection
• Explicit memory – revealed when performance on a task requires conscious recollection of past experiences.
• “Semantic memory consists of the organised knowledge that we possess about language and about the world.
- episodic memory: events and experiences

178
Q
