Aspergers is an autistic spectrum disorder but the patient will have normal language ability, cognitive development and intelligence.
IQ will be above 70, unlike other ASD.
Much better prognosis than autism.

61
Q

How would investigate this patient to rule out other possible diagnoses and confirm autism?

A

A more detailed history focusing on developmental and behavioural features consistent with the ICD 10 and DSM Criteria for ASD/Aspergers.
Collateral history from mum and also school.
Rule out other conditions such as depression and anxiety by using screening tools
Refer the child to the autism team who would then conduct autism diagnostic assessment.

62
Q

A

Support and education for the patient
Support and education for the family e.g. National Autistic Society.
Behaviour therapy - reinforce positive behaviours
Speech and language therapy

63

64
Q

Counsel a somatisation

A

Physical manifestation of psychological stresses. When your body is hurt, your brain detects this and sends out signals of pain to protect you. What is happening is your brain is detecting that you are emotionally hurt and sending out signals to the wrong places.
This DOESN’T mean the pain in not real, it is very real. It just means the solution isn’t as easy as if you break your arm
Tend to occur most when you are experiencing that stress eg going to school or just before school

65
Q

What is the management for a child with somatisation associated with school?

A

Don’t do graded return to school - they should attend as normal
Don’t reinforce taking time off/getting out of homework
“would like to invite your parents in to talk about this at a different point, can help explain that this isn’t you just making it up”
Distraction techniques - relaxation etc
Some people find mindfulness techniques/yoga v.helpful
Refer to psych to help in case this doesn’t go away with the techniques we’ve discussed but takes time, until then make a diary of symptoms and how you’re feeling at the time, what stresses you have coming up
Referral to CAHMS - CBT + Family therapy
CBT - you will have to attend multiple sessions for this to work so be prepared for this

66
Q

Counsel a lady on lithium and is pregnant

A

So although certain medications carry some risks to the baby in terms of congenital defects etc these are often small and frequently outweigh the risks of stopping the medication. Risk of stopping the medication include withdrawal symptoms and relapse which could actually result in more harm to both you and the baby. Often in pregnancy and after the birth, mental health conditions are worse this is because there’s lots of emotions and changes going on in your body and in your environment, and sometimes women who didn’t have mental health conditions before getting pregnant suffer from things like depression or psychosis and so this is another reason we sometimes like to continue medication.

There are 3 main options that we like to consider in this situation
Continue medication
Change medication to a different try or try psychological treatment
Stop the treatment all together

We on which option to take depending on risk to both mum and baby. From what you’ve told me so far about your history of bipolar and also relapses I think it is really important that you continue to take your lithium medication. If you feel really really strongly about not taking it we could discuss trying some of the different medications you may have tried before or high intensity psychological treatment such as CBT which you may have also had before but if these did not work in the past it is a risk that you would relapse if you switch to these methods.

67

T - usually normal
I - variable
C - usually normal

68
Q

A

Start:
You’ve really gone through a lot today. Would you mind telling me what happened?

Middle:
It sounds like you planned things through very carefully, how did you end up coming to hospital?

End:
How do you feel now?
Do you regret trying to hurt yourself?
Do you have any further plans to harm yourself?

SEE SAFE G

69
Q

After talking to patient who has attempted suicide what would you do for the investigation?

A

Document EVERYTHING
Formal capacity/MHA assessment
Physical assessment
Rule out head injury
Give antidote if needed (NAC/paracetamol, activated charcoal → decreases gut absorbance of some substances)
Wound healing of sutures
Analgesia
Risk assessment incl MSE (if not done already)
Meticulous planning, final acts, isolation at time, precaution to avoid being found, definite intent to die, believed method to be lethal, violent method, ongoing wish to die
Immediate
Admission if high risk
Try and remove immediate triggers
Plan for future similar thoughts - who to tell, how to get help
Crisis card
Follow up
1/52 appt
Treat any underlying disorders
If psychotic → refer to EIS
Benefit of HTT?
Biological therapies: antidepressants (short prescription and regular review to avoid stockpiling)
Psychological therapies: IAPT self referral, CBT, mentalisation treatment, transference focused therapy
Social therapies: sick note for time off work, support groups, family support
Coping strategies
Distraction techniques, mood raising activities
Harm reduction - not sharing blades, learn first aid
Prevention - sharps out of reach, avoid triggers, surround with support
Alternatives - squeeze ice, bit food, snap rubber bands, red food dye/marker pen for blood
