what are some symptoms of myasthenia gravis
- intermittent double vision
- slurred speech
- difficulty swallowing
- symptoms are worse at the end of the day
what are some signs of myasthenia gravis
- ocular, facial and bulbar weakness
- fatiguable symptoms
- bilateral fatiguable ptosis
- bilateral facial weakness
- fatiguable dysarthria
- poor cough and neck flexion weakness
- mild fatiguable Proxima limb weakness
what is ptosis
- drooping of upper eyelid
what is the pathogenesis of myasthenia gravis
- autoimmune disorder = AB’s to EACh receptor at post-synaptic NMJ
- association with other autoimmune disorders
- may be associated with thyme hyperplasia or thymoma
- affects young women in 20’s and older men in 70’s
- fatiguable weakness of ocular, bulbar, neck, respiratory and/or limb muscles
- AB’s to ACh receptor present in 85% of cases
- single fibre EMG and repetitive nerve stimulation also present
what is the management of myasthenia gravis
- managed with pyridostigmine (anti-acetylcholine esterase) and immunosuppressive therapies (steroids and IV immunoglobulin)
if tongue is deviating towards the left what does that mean
- left hypoglossal nerve isn’t working
what can hypoglossal nerve damage be a complication of

what are some signs and symptoms of motor neurone disease
- progressive dysarthria/anarthia over months
- progressive dysphagia over months
- emotional lability and change in personality

- involved motor and speech tics
- involuntary vocalisations
- co-morbid and anxiety and obsessive symptoms
what can speech and motor difficulties be brought on by
- bacterial meningitis
what is a hemifacial spasms
- blood vessel that supplied posterior brain that crosses brainstem and touches nerve root for facial nerve on one side and irritates it and causes that continuous firing
- twitching of muscles of face
- gradually worsening
