38
Q

What is AN-focused family therapy ?

A

Non-blaming, stop accommodating patterns, family starts by taking contorl of the child’s eating, then moves to giving that control back to the child, finishes with relapse prevention

39
Q

When is CBT-ED useful?

A

CBT-ED or Adolescent-focused psychotherapy as a second option CBT-ED works well as an alternative (Craig et al., 2019)

food as the key element of treatment, single most important element is nutrition/exposure to foods (physical, cognitive, emotional and sociol benefits)

50
Q

What are the difference between underweight cases and unon underweight cases when looking at common elements of what works?

A

Underweight cases - not clear whether the rest of these therapies does much more (Waller & Raykos, 2019) and Non-underweight cases - extra value in the psychological element of therapy

51
Q

Who covers the therapies that are most strongly suppoted by the evidence?

A

Nice, which is why it should be used as a priority and in a resource limiting setting (everywhere), drives commissioning advice for NHS, addresses isseus around case management and patient expeirence

52
Q

What about other approaches not mentioned by NICE?

A

Not meeting the NICE criteria of enough high quality research. Not as effective as what the guidelines recommend. Still not including very weak research (e.g. dolphin therapy) or unsupported clinician opinion

53
Q

What are some ase/risk management that are needed?

A

Medical monitoring and management (addressing the risks covered last time), intensive tretments

54
Q

What are intensive treatments (in and day patients)

A

Use varies across cultures (e.g., almost universal in Germany, rare in UK). Necessary for management of high-risk cases. Can be good for weight restoration

55
Q

What are some limitation of intensive treatments

A

Almost no evidence of establishing recovery. Very expensive. Risk of creating dependence

56
Q

Some weaker aproaches could have been what - NICE?

A

Therapies that have been recommended in the past (NICE, 2004) but have not been retained (NICE, 2017) because they were overtaken by stronger evidence

57
Q

What are approahces that have weaker evidence ?

A

Medication, Physical intervention (neuromodulation, leucotomy) and other therapies (DBT, IPT, FIT) Mentalisation-based therpay, ACT, Mindfullness based approahces, family therapies not based on food/eating

58
Q

How can SSRI medication be used as a intervention for eating disorders?

A

SSRI medications (e.g., fluoxetine/Prozac) at high doses for BN: Enhances functional serotonin, Reduces binges for some people while taking it, but not for longer, Potential withdrawal effects (‘SSRI discontinuation syndrome’)

59
Q

How can novel antipsychotic for An be used as intervention for eating disorders?

A

olanzepine, quetiapine, risperidone. Reduce anxiety?? enhance weight gain through metabolic slowing????

60
Q

What are two meidcations that are used ?

A

SSRI and novel antipsychotics

61
Q

What are some physical interventions that have week evidence

A

Neuromodulation and leucotomy

62
Q

What are neuromodulation

A

Transcanial stimulation methods seem to reduce depression slightly, but no eviednce yet that this work specificall in ED

63
Q

What are leucotomies?

A

Brain surgery, rarely used, has been used for chronic anorexia nervosa with extreme OCD, evidence is annecdotal and poor

64
Q

Other psychological therapies with some evidence (weak)

A

dialectical behaviour therapy (DBT), Interpersonal psychodynamic approaches (FIT), Focused psychodynamic approaches (FIT), integrative cognitive affective therpy

65
Q

What is Dialectical behaviour therapy DBT

A

Reduces impulsive behaviours in BED/BN, but little change in core pathology. Evidence for anorexia nervosa is very limited

66
Q

What is interpersonal psychotehrapy (IPT)

A

works for BN, but slower and less effective than CBT

67
Q

What is Focused psychodynamic approach ?

A

effective for anorexia nervosa, but needs to be replicated in other countries

68
Q

Is Integrative cogntiive affective thepry effecitve?

A

less effective than CBT

69
Q

What are some Psychological therapies with little evidence so far (despite trying)?

A

Mentalisation-based therapy, ACT, mindfulness-based appraoches, family therpies that do not focus on food or eating

70
Q

What is mentalisation based therapy?

A

Mainly used in personality disorders, effectiveness for eating disorders lower than CBT, takes 18 months

71
Q

What is ACT

A

Acceptance and commitment therapy

72
Q

What are the limitations of deep brain stimulation?

A

Side effects. Not similarly effective for all. And, crucially, DBS also fails to deal with non-motor symptoms. Confounded by DBS typically being used in later stage disease. It may actually make some non-motor symptoms worse

73
Q

What are alpha synuclein?

A

another problematic protein (think back to amyloid with regards to Alzheimer’s disease)

74
Q

How does Alpha synuclein affect Lewy bodies?

A

Not sure what it does in health, but it appears that misfolding and aggregation (clumping) into what are called Lewy bodies, is a hallmark of PD

Happens throughout the brain. Dopamine neurons in substantia nigra may be particularly vulnerable. Crucially, this explanation may also account for non-motor symptoms

75
Q

How does the cerebellar dysfunction?

A

Like basal ganglia, no direct projection to the lower motor neurons – instead modulate activity of upper motor neurons

76
Q

What is the cerebellum?

A

Contains approx. half total number of CNS neurons. Just 10% of total brain weight. Projects to almost all upper motor neurons.

77
Q

What is dysarthria?

A

disruption of fine control of speech, slurring

78
Q

What happens when cerebellum is damaged?

A

When damaged, the resulting impairment in movement is often described as ataxia. Two types of impairment:
- Disturbances of posture or gait
- Decomposition of movement
Voluntary movement loses fluidity and appears mechanical, slow and robot-like. Intention tremor (not like the PD resting tremor) and Dysarthria

79
Q

What is ataxia?

A

A collection of disorders, unified by their symptoms, rather than their causes.
Can be defined most simply as a loss of voluntary co-ordination of muscles – it is thus a neurological finding in a patient, and not a disease (though it may be caused by various diseases)

Types: can be confusing as they are divided up in slightly different ways depending on what source you read

80
Q

What are the different types of ataxia?

A

Focusing on types of symptom: cerebellar, sensory, vestibular

Focusing on type of cause: acquired, hereditary, late onset cerebellar dysfunction

Focussing on more detailed diagnosis: Freidrich’s ataxia, ataxia-telangiectasia, spinocerebellar ataxia, episodic ataxia, vitamin-E deficiency related.

81
Q

What are the different types of distinct symptom pattenrs?

A

Gait problems, use of proprioceptive ifnor, impaired/altered reflexes (Fredreich’s ataxia)

Ataxia with oculomotor apraxia

Ataxia telangiectasia (rare genetic disorder): nystagmus (eye movement prob)

Oculoot Ataxia: impaired co ordination of eye and head movement

82
Q

What are motor neuron disease?

A

Motor neuron degeneration and muscle wasting.
Why muscle wasting? Degenerative, progressive incurable
Causes? ~10% of cases have genetic component – environmental, toxic, viral and other factors implicated in the other 90% - i.e. we don’t know!

83
Q

What is the motor neuron disease incidence?

A

Anyone, but more common in men. But risk strongly modulated by age. About 5,000 people in the UK have it right now. Symptoms, rate of progression and life expectancy highly variable.

84
Q

What are the different types of motor neuron diseases?

A

MND is used interchangeable with ALS (amyotrophic lateral sclerosis). ALS is subtyp of MND (most common)

SUbtype relates to effect on either upper or lower or both motor neurons.

ALS affects both: all motor neurons, all muscles.

There is often also altered cognitive function (usually mild), ability to communicate, and affective changes
Complications arising due to impaired respiratory function is often the cause of death

85
Q

What are the treamtent and latest research for motor neuron disease?

A

Identify biomarkers (early diagnosis)
Identify risk factors
Novel neuroprotective drugs
Gene therapies
Drug to cure, and slow progression
Clinical & technological interventions to improve & prolong life
