52
How does Mirtazapine work? What is it used for?
Mirtazapine is a NaSSA: noradrenergic and specific serotonergic antidepressant. It blocks a-2 adrenergic receptors, serotonin 5HT receptors, and histamine H1 receptors. Its strongest activity is blocking H1. This causes sedative and hypnotic effects. After a period of use, these effects wear off. It is primarily used to treat mood disorders such as depression.

56
What is a section 4?
A section 4 is an emergency measure which allows you to detain a patient for up to 72 hours, if they have a mental disorder, it is urgently necessary for them to be admitted, and waiting for the second doctor would cause an undesirable delay. One doctor and one AMHP needed.
57
What is a section 5 (2)? When used?
Allows one doctor to detain an informal patient or inpatient for up to 72 hours while waiting for a second doctor and AMHP to assess for section 2/3. The doctor must be F2 and above.
58
What is a section 5 (4)? When used?
Allows a mental health trained nurse to detain a voluntary mental health patient for up to 6 hours or until the section 12 approved doctor arrives. Applicable if: patient needs to be kept in hospital for their own/others safety, or it is so urgent that it is not practicable for a report to be provided to the hospital managers.
59

62
What is the function of glutamate?
Glutamate is the most common excitatory neurotransmitter in the brain. It has a role in synaptic plasticity, which means it is involved with cognitive functions such as learning and memory.
63
What can happen if there is a buildup of glutamate in the brain?
It is neurotoxic and can lead to a loss of neuroplasticity.
64
How is stress harmful to the brain?
Stress causes a buildup of glutamate in the brain which is neurotoxic. It also neurotoxic via elevation of serum cortisol levels, especially in the hippocampus.

67
What are the pyramidal tracts?
Nerve fibres which run from the cerebral cortex to the brainstem (corticobulbar tract) or spinal cord (corticospinal tract), involved in controlling the voluntary motor functions of the body. They run through the medullary pyramids.
68
What are the extrapyramidal tracts?
Part of the motor system network causing involuntary actions. They target lower motor neurones in the spinal cord that are involved in reflexes, locomotion, complex movements and postural control.
They consist of the rubrospinal, reticulospinal, vestibulospinal and tectospinal tracts.
69

2. Change to another SSRI/ trazadone/ mirtazapine
3. SNRI eg venlafaxine
77
What are the issues with paroxetine?
Paroxetine has a short half life so needs to be taken more regularly and levels fluctuate. This increases the risk of discontinuation symptoms making it harder to come off. It also causes weight gain.

'Paradoxical reaction' in 1% of population - increased anxiety, disinhibition, hyperactivity and aggression. Similar reactions to other depressants eg alcohol, barbuturates.
214
An elderly lady with dehydration says she does not want IV fluids. The last time she was in hospital she had a UTI and her blood was taken against her will because she was deemed not to have capacity. Would you give her the fluids?
Autonomy vs best interests.
Capacity:
Understands the information, can retain it long enough to make the decision, weigh up the options and communicate their decision.
Capacity is assumed until proven otherwise. It is assessed on a decision-by-decision basis so the previous event does not mean she doesn't have capacity now.
Must be supported to make her own decisions including being given information in different ways - what is she worried about? If after all this she still refuses, don't treat her because she has the right to make unwise decisions.
If she doesn't have capacity, treatment must be in her best interests and the least restrictive option.
215
