Neurology Flashcards
Management suspected TIA
300mg aspirin OD until diagnosis established (or 14 days) or DOAC if AF
Refer TIA clinic urgently for CT head, carotid doppler
If bleeding disorder urgent CT head
Clopidogrel 75mg OD lifelong
Atorvastatin 80mg
Bloods- FBC, U+E, lipids, LFT, CRP, HbA1c, and random glucose.
INR if on warfarin, or clotting screen if considering DOAC.
ECG, looking for AF or recent MI
Driving advice stroke and TIA
1xTIA must not drive for 1 month but need not notify DVLA.
Multiple TIAs must not drive for 3 months and must notify DVLA. Stroke must not drive for 1 month but may not need to notify DVLA. Driving may resume after 1 month if there has been satisfactory clinical recovery. DVLA does not need to be notified unless there is residual neurological deficit 1 month after the episode and, in particular: visual field defects, cognitive defects, impaired limb function.
Management acute stroke
Admit, 999 if<4.5hrs
Thrombolysis if <4.5hrs
Thrombectomy if <6hrs or wake up stroke
Differentials of TIA
Hypoglycaemia
Migraine aura
Hypotension with or without syncope
Confusion
Isolated vertigo

Anxiety
Transient global amnesia
Drop attacks
CFS symptoms

Un-refreshing sleep
Orthostatic intolerance
Ix for CFS

If associated with a viral illness: EBV, CMV, HIV
If bacterial infections, inflammatory joint pain, muscle pain, or lupus or vasculitis: immunoglobulins,
ANA, RF, anti-CCP,
CK, cortisol
Treatment CFS
Education, support groups
CFS MDT
Energy management
Graded exercise
If fibromyalgia consider amitriptyline/duloxetine
Increased salt intake, compression socks for POTS
Differentials in CFS
Anaemia
Malignancy (weight loss/night sweats)
OSA (snoring/stopping breathing)
Cardiac (syncope, during exercise SOB)
Autoimmune condition (RF/SLE)
Addison’s
Diabetes
HIV/CMV/EBV
Hypothyroidism
Neuro symptoms to screen for in dementia assessment
Gait, balance, vision, speech and language, Parkinsonism, upper motor neuron symptoms.
Definition of dementia
Progressive impairment 2+ cognitive domains (memory, language, behaviour, or visuospatial or executive function) leading to significant functional decline (enough to affect ADLs) that cannot be explained by another disorder or adverse effects of medication
Behavioural symptoms to ask about in dementia testing
Apathy, sleeping problems, restlessness, agitation, calling out, repetitive behaviour, wandering, socially inappropriate behaviour, aggression, disinhibition, changes in eating and drinking behaviour.
Cognitive symptoms to ask about in dementia testing
Memory, language, insight, judgement, problem-solving, processing speed, concentration and attention, ability to use objects.
ADL impairments to ask about in dementia testing
Continence and toilet hygiene, bathing, eating and drinking, cooking, shopping, dressing, shaving and hair care, socialising, housework, gardening, transport, managing money, employment.
Risks of dementia
Safety in the home, financial mismanagement, wandering, elder abuse, aggression towards others, inappropriate or unwanted sexual behaviour, alcohol and drug misuse, medication adherence issues, dangerous driving, self neglect
Ix for ?dementia
Bloods (FBC U+E LFT, bone, TFTs, B12, folate)
CT head
?syphilis/HIV
Screen of polypharmacy, alcohol/drugs
Referral criteria adult memory impairment
Routine memory team ref unless:
Age<65 with prominent:
psychiatric symptoms or uncertain diagnosis, CMHT
Age>65 prominent psychiatric symptoms or complex challenging behaviour- older adults mental health

When can epilepsy be diagnosed?
2+ unprovoked epileptic seizures, >24 hrs apart or
one unprovoked (or reflex) seizure with>60% probability of further seizures, or
identified epilepsy syndrome.
