Neurological history taking Flashcards
3 key questions to ask when doing a ‘neuro clerking’?
- is there a lesion/pathology (structural vs functional; onset + course)
- where is the pathology/lesion
- what is the lesion/pathology
How to check for spasticity in the upper and lower limb?
Spasticity is velocity dependent -> need to perform QUICK movements to detect it
A. Upper limb -> quickly shake hand (few times - passive movement of pt’s hand)
B. Lower limb quickly check knee -> ‘throw that on bed’
Where is the weakness in Guillan Barre syndrome?
Bi-lateral + distal or proximal
What’s the weakness pattern following the stroke?
Unilateral
(not to the lesion but for example weakness in limbs + eyes homologous hemianopia)
3 main features of Parkinson’s
- Rigidity
- Resting tremor
- Bradykinesia
Tremor - possible types (3)
Tremor:
- cerebellar -> essential tremor
- extra- pyramidal
- resting tremor -> Parkinson’s
What may be meant by ‘blackout’?
- LOC
- loss of vision
- loss of memory
A patient comes and says they have got e.g. dizziness (or any other symptom), what do we need to ask?
Make sure you know exactly what they mean by the symptoms e.g. what happens when you feel dizzy?
What is onset?
What is course?
It’s extremely important to ask about the onset and course
- Onset - when it started
- Course - what has happened between the start of the symptoms and until now
What to ask in pt with TIA in terms of PMH/risk factors?
- AF
- hypertension
- high cholesterol
- CVD
What is Hoover’s sign in neurology? (in context of leg paresis = weakness)
(just what does it test for)
Hoover’s test -> help to distinguish between organic and non-organic (functional) nature of paresis
- it depends on synergistic contraction principle
How to perform Hoover’s test?
Patient lies on their back -> examiner holds and lifts (slightly) their heels
Ask patient to straight afected leg (lift it) and if we cannot feel a downwards pressure on the leg that is not lifted -> pt is not ‘trying’ -> functional weakness
(if we cannot feel the pressure = positive test)
If we can feel downward pressure on the opposite leg -> organic cause of weakness
Functional weakness
- causes
- management
- past trauma
- dissociation at brain level
- somatic symptoms
Management:
- CBT -> for cause/psychotherapy
- Physiotherapy -> for physical symptoms
Optic neuritis - what happens?
Management
Optic neuritis
Inflammation or compression of an optic nerve
Management: steroids -> to speed up the recovery
Characteristics of demyelination symptoms?
Sx worsen over days/ hours -> plateau for days -> spontaneously improve
