Discussion
• What are the differential diagnoses ?

– No as P.V.D.• What referrals would you make?
– Physio; OT; S/worker; chiropody; diabetic nurse• What medication would you start?
– Calcichew D3 forte (?fludrocortisone if still postural bp drop)• Any other suggestions?
– Pendant alarm
Clinical scenario 3
• 78yr female
• Widow. Lives alone.
• Known HT,IHD,OA hips & knees
• Recurrent falls “Legs won’t do what I want them to do” “feet feel nailed to the floor” “my body turns but legs feel stuck & I fall over”
• 6/12 deterioration in walking
• Worsening memory – reliant on daughter
• New urinary incontinence – frequency, urgency,nocturia – too slow to WC

• SR Bp 140/86 – no drop
• Abdo – NAD
• Upper limbs normal
• Lower limbs – hypertonic, hyperreflexic
• Right upgoing plantar
• Eye movements / fundi - normal
Discussion
• What are the differential diagnoses?• What one investigation would you do?• What are her falls risk factors?• What are her osteoporosis risk factors?• What referrals would you make?• Which drugs need reviewing?• What drugs would you start?• What would you tell daughter?
• What are the differential diagnoses?– Arteriosclerotic parkinsonism; normal pressure hydrocephalus;
cervial myelopathy• What one investigation would you do?
– CT brain• What are her falls risk factors?
– >2 falls/yr; incontinence; >3 drugs; cognitive impairment; gait/balance abnormalities
• What are her osteoporosis risk factors?– Frail; housebound; falls risk
• What referrals would you make?– Physio; OT; continence service; S/worker; ?CPN
• Which drugs need reviewing?– Stop bendrofluazide (worsen incontinence); ?madopar trial

Clinical scenario 4
• 72 yr male• Good health• No medications• Colles # 2yrs ago• Smokes 10/day• Alcohol 4u/wk• Car crash – sudden swerve onto pavement and
then into wall.• Next thing ambulance arriving.
• Pt has no memory of events & no warning
• Denies L.O.C.
• A&E : Examination normal. ECG & cardiac enzymes normal - discharged
• Previous similar episode – Colles #
• Occas dizzy if looks up or turns quickly-lose sense of balance
Discussion
• What are the differential diagnoses?
• Why is this not epilepsy?
• What investigations would you want to carry out?
• What is the treatment of choice for this condition?
• What are the differential diagnoses?– Syncope:vaso-vagal,carotid sinus hypersensitivity,
arrhythmia
• Why is this not epilepsy?– See next slide
• What investigations would you want to carry out?– Postural bp; bloods; ECG; Tilt table; carotid sinus
massage
• What is the treatment of choice for this condition?– Pacemaker
Seizure v syncope
Seizure SyncopeAura N/V/sweaty/pallor
Prolonged confusion Quick recoveryProlonged tonic-clonic Short tonic-clonic(coincides with LOC) (After LOC)Tongue biting No tongue bitingBlue face(Incontinence)
Syncope made easy
• Make diagnosis by history• Examination incl postural bp• ECG• Possible diagnoses:
– Vasovagal syncope– Carotid sinus hypersensitivity– Postural hypotension– Cardiac arrhythmias– Structural cardiac/cardiopulmonary disease
Is heart disease present or absent?
• Based on Hx(supine,palps,exertion), examination or abnormal ECG
• If NO heart disease, excludes cardiac cause of syncope (low mortality)
• If heart disease present then strong predictor of cardiac cause(low specificity) – higher mortality
Clinical scenario 5
• 69yr female• 4 fits in 2 yrs and 3 unexplained falls• On sodium valproate – not controlling fits• Presents with #humerus post fit• Witness “Pallor” “Limbs jerking”• Dizzy pre-fits. Urinary incontinence.• Not confused on waking – “tired & washed out”• Examination - normal
What could be the diagnosis?
Give 5 possible diagnoses
What tests would you like to do?
What are her osteoporosis risk factors?
• Give 5 possible diagnoses– Uncontrolled epilepsy; hypoglycaemia; vaso-
vagal syncope; arrhythmia; C.S.H.
• What tests would you like to do?– Tilt table; carotid sinus massage; internal loop
recorder
• What are her osteoporosis risk factors?– Valproate; previous #
Clinical scenario 6
• 59yr female• Intermittent “dizziness” with associated loss of
balance.• Brought on by head movements(eg bending
forward or head extension) or turning over in bed• Recent viral illness• No medications• No alcohol/smoking• Examination - normal
Discussion
• What one question would you like to ask the patient?
• What possible diagnoses?
• What could you do to confirm the diagnosis?
• What is the treatment?
• What one question would you like to ask the patient?– Symptoms of vertigo?
• What possible diagnoses?– BPPV; postural hypotension; C.S.H.
• What could you do to confirm the diagnosis?– Dix-Hallpike manoeuvre
• What is the treatment?– Epley manoeuvre
Benign paroxysmal positional vertigo (BPPV)
• Commonest causes of vertigo
• Due to otoconial debris in semicircular canals
• Increases with age ; female>male
• Brief episodes (<1 min) vertigo (+/- imbalance) with specific head positions
• Episodic lasting few days – months
• Asymptomatic intervals months - yrs
Causes of BPPV
• Idiopathic
• Advanced age
• Post head trauma
• Vestibular neuritis
• Examination - normal
Dix-Hallpike manoeuvre
• Produces symptoms and torsional nystagmus
• Latent period
• Lasts 10-20 secs
