Q

features of temporal lobe seizure

A

May occur with or without impairment of consciousness or awareness

An aura occurs in most patients
typically a rising epigastric sensation

also psychic or experiential phenomena, such as déjà vu, jamais vu

less commonly hallucinations (auditory/gustatory/olfactory)

Seizures typically last around one minute

automatisms (e.g. lip smacking/grabbing/plucking) are common

Q

key features of MND

A

asymmetric limb weakness is the most common presentation of ALS

the mixture of lower motor neuron and upper motor neuron signs

wasting of the small hand muscles/tibialis anterior is common
fasciculations

the absence of sensory signs/symptoms

vague sensory symptoms may occur early in the disease (e.g. limb pain) but ‘never’ sensory signs

doesn’t affect external ocular muscles

no cerebellar signs

abdominal reflexes are usually preserved

sphincter dysfunction if present is a late feature

Q

how is a chronic subdural managed?

A

an incidental finding or if it is small in size with no associated neurological deficit can be managed conservatively with the hope that it will dissolve with time.

If the patient is confused, has an associated neurological deficit or has severe imaging findings then surgical decompression with burr holes is required.

Q

features of Anterior Inferior Cerebellar Artery (AICA) i.e. Lateral Pontine Syndrome stroke

A

ipsilateral auditory deficits e.g. deafness
vertigo and vomiting
ipsilateral facial paralysis
ipsilateral cerebellar dysfunction.

This is due to the involvement of the facial and vestibulocochlear nerves within the brainstem and cerebellum.

97
Q

how does mononeuritis multiplex present

A

acute or subacute loss of sensory and motor function of individual nerves.

The pattern of involvement is asymmetric, however, as the disease progresses, deficit(s) becomes more confluent and symmetrical, making it difficult to differentiate from polyneuropathy.
