Q

What is the Pathophysiology of Major Depressive Disorder?

E.g. Parkinson’s disease, dementia, and multiple sclerosis.

Endocrine disorders especially thyroid dysfunction and hypo/hyperadrenalism (e.g., Cushing’s and Addison’s disease).

Substance use or medication side effects
e.g. steroids, isotretinoin, alcohol, beta-blockers, benzodiazepines, and methyldopa.

Chronic conditions

Q

Describe the cycle of anxiety seen in OCD?

A

Obsessions lead to anxiety, which leads to the compulsive behaviour, which leads to a temporary relief in the anxiety.

Shortly after the temporary improvement in anxiety the obsession reappears, leading to further anxiety, further compulsive behaviour with a temporary relief.

This cycle continues and each time gets more engrained in the person’s behaviour. Without doing the compulsions, the person feels they cannot get relief from their anxiety.

Q

Explain Schizophrenia in simple terms

A

Schizophrenia is a condition that affects how the brain processes information.

Normally, the brain is very good at understanding reality, deciding what is important and what is not, and organising thoughts in a structured way.

With schizophrenia, the brain struggles to understand the world, makes mistakes in deciding what information is important and organises thoughts in a confused way.

This can lead to strong beliefs that do not fit with reality, called delusions. They may also experience voices that are not there, called hallucinations.

The disorganised thoughts can lead to unusual speech and behaviours, which is called thought disorder.

When these symptoms occur, it is called psychosis.”

Q

What are the specific features of Schneiders first rank symptoms?

A

Auditory Hallucinations:

  • Thought Echo: Hearing one’s own thoughts spoken aloud, as if they are echoing back.
  • Voices Commenting: Hearing voices that provide a running commentary on the person’s actions or thoughts.
  • Voices Conversing: Hearing multiple voices talking to each other, usually discussing the person in the third person.

Thought Disorder

  • Thought Insertion: The belief that thoughts are being inserted into one’s mind by an outside force.
  • Thought Withdrawal: The belief that one’s thoughts are being taken out or removed by an external force.
  • Thought Broadcasting: The belief that one’s thoughts are not private but are being broadcasted or accessible to others.

Delusional Perception:

  • The person has a normal perception (like seeing a particular object or event) but interprets it with delusional significance, such as thinking the perception has a unique or personal meaning (e.g., seeing a red car and concluding that it means they are being watched).

Passivity Phenomena (or Delusions of Control):

  • Made Actions: Belief that one’s actions are controlled by an external force, as though someone else is “making” them move.
  • Made Impulses: Belief that impulses to act are not one’s own but are imposed by an external force.
  • Made Feelings and Emotions: Belief that one’s emotions or sensations are being controlled or influenced by someone else.

when schizophrenia is resistant to other antipsychotics (2 have been tried)

A
  • Selective Serotonin Reuptake Inhibitors (SSRIs)
  • Serotonin and Noradrenaline reuptake inhibitors (SNRIs)
  • Tricyclic Antidepressants (TCAs)
  • Others: Mirtazapine, Vortioxetine
230
Q

What is the mechanism of action of TCAs?

A

TCAs block the reuptake of serotonin and noradrenaline by the presynaptic membrane.

They also have additional actions, including blocking acetylcholine, alpha adrenergic and histamine receptors, which give them anticholinergic and sedative side effects.

231
Q

What is the mechanism of action of SSRIs and SNRIs?

A

SSRIs work by blocking the reuptake of serotonin by the presynaptic membrane on the axon terminal. This results in more serotonin in the synapses throughout the central nervous system, boosting the communication between neurones.

SNRIs work by blocking the reuptake of serotonin and noradrenaline by the presynaptic membrane. This results in more serotonin and noradrenaline in the synapses throughout the central nervous system.

232
Q

Give examples of some SSRIs

A

Sertraline
Citalopram

Fluoxetine
Paroxetine

233
Q

  • Citalopram: prolong QT interval leading to torsades de pointes. bad in heart disease
  • Fluoxetine: long half life and safe in children
  • Paroxetine: cause weight gain and discontinuation symptoms but safer in pregnancy
234
Q

What are the key side effects of SSRIs?

A

SSRIs

Stomach issues - Diarrhoea, nausea, vomiting, increased risk of GI bleeding
Sexual dysfunction - loss of libido, ED, orgasms
Risk of suicidal thoughts and actions increased
Irritability, agitation, anxiety (in first weeks)
SIADH leading to hyponatraemia

235

Antagonism of muscarinic receptors

  • dry mouth
  • blurred vision
  • constipation

A

Those with a history of heart disease and high blood pressure

241
Q

What kind of antidepressant is Mirtazapine?

What is its mechanism of action?

What are the key side effects?

A

Noradrenergic and specific serotonergic antidepressant (NaSSA)

  • Blocking α2-adrenergic receptors, which increases the release of norepinephrine and serotonin.
  • Acting as an antagonist at specific serotonin (5-HT2 and 5-HT3) receptors, which helps reduce side effects commonly seen with SSRIs (such as nausea).
  • Also blocks H1 histamine receptors, which contributes to its sedative effects.

Highly Sedative and causes increased appetite/weight gain

242
Q

What are some considerations when starting antidepressants?

A

Brain has reward pathway mesolimbic pathway
Primary neurotransmitter is dopamine

Addictive substances and behaviours release dopamine within the mesolimbic pathway providing a pleasurable reward.

Repeated exposure reduces number and sensitivity of dopamine receptors requiring an increasingly strong stimulus

Cues for substance or behaviour are embedded in the amygdala. stress and other events can act as cues triggering cravings.
