Neurology - cerebellar PULSE: Preparation for Finals Tutor name
TuBS attendance • https://tutorialbooking.com/
Session overview • Common cerebellar pathologies • How to present your findings • Demonstration of clinical signs • Case presentations and OSCE questions
What is the purpose of an OSCE? “This station tests a student’s ability to perform an appropriate focussed physical examination, demonstrating consideration for the patient, and to report back succinctly describing the relevant findings. It also tests a student’s clinical judgement i.e. the ability to decide the differential diagnosis, choose investigations and formulate a management plan.”
Presenting your findings • What were you asked to do? • What were your key positive findings? • What were the important negative findings? • What does this mean? • How would you complete your examination, and what investigations would you do?
Common cerebellar conditions in the OSCE • Tremor • Speech difficulties - dysarthria • Balance problems - ataxia
Cerebellum • What it does: motor control and co-ordination • Findings in cerebellar disorder: DANISH • Common conditions linked with cerebellar disorder
What are the signs of cerebellar dysfunction? • DANISH! • Dysdiadochokinesis • Ataxia • Nystagmus • Intention tremor • Slurred/stacatto/slow speech • Hypotonia
How would you tell a central from a peripheral cerebellar lesion? • Hemisphere - ipsilateral deficits such as dysmetria, disdiadochokinesis, intention tremor • Vermis - generalised or truncal deficits such as ataxic gait, dysarthria, nystagmus, vertigo
What are the causes of cerebellar dysfunction? • POCS/ Tumour/Para-neoplastic syndromes • MS • Arnold-Chiari malformation • Friedrichs ataxia • Alcohol/ Thiamine deficiency • Anti-epileptic medications
Example case presentation • 60 year old man, looks unkempt. Asked to examine his cerebellar system.
Cerebellar examination • WINDEC • STAND BACK INSPECT (comment on any obvious findings)
What are the different patterns of speech disturbance? • Dysphasia; Brocas (expressive/non-fluent), Wernickes (receptive/fluent), conduction, mixed • Dysarthria; cerebellar, extrapyramidal, bulbar/pseudobulbar palsy • Dysphonia; extrapyramidal, myaesthenia, GuillaineBarre
Hands – both hands shaky at rest, evidence of past pointing and dysdiadochokinesis. Upper limb tone slightly reduced. • Face and speech – eye movements appear normal but patient has difficulty following demands. Speech is slurred. Skin has a yellow tinge. • Gait – broad based ataxic gait, furniture walking to door. Please present your findings.
Completing your examination • Full neurological examination of the limbs and cranial nerves • You will still elicit cerebellar signs if you perform neuro limb examination • Early identification of clear cerebellar signs may allow you to perform focused cerebellar examination • Focused history • Speech
Gait disturbance • How would you classify disturbances in gait?
Gait disturbance • Asymmetrical • Hemiplegic (unilateral pyramidal) • Foot drop • Antalgic • Functional • Symmetrical • Normal pace • Cerebellar ataxia (BROAD-based) • Spastic paraparesis (scissoring) • Sensory ataxia (HIGH-stepping) • Proximal myopathy (waddling) • Frontal (apraxic) • Small pace • Parkinsonian (festinent)
