Q

Lateralisation of cerebellar signs

A

Ipsilateral to lesion

Bilateral cerebellar signs more likely to represent a global pathology e.g. alcohol, MS, phenytoin

Q

Investigations for cerebellar syndrome

A

ECG: arrhythmia (DDx brainstem stroke)
Bloods: EtOH (FBC, U+E, LFTs), thrombophilia (clotting), Wilson’s (low caeruloplasmin)
CSF: oligoclonal bands
Imaging: MRI is best to visualise the posterior cranial fossa
Audiometry: CPA lesion (pure tone audiometry)
