MS and MND Flashcards
What is multiple sclerosis?
Neurological condition autoimmune destruction of myelin sheath of neurones in CNS
- loss of myelin sheath - demyelination
Aetiology unknown - genetic/environmental factors likely
Neurological signs and symptoms disseminated in time and site
Where in the world is MS most common?
Females or males?
Age of onset?
Most common near the poles of the earth
- women > men
- mean onset age 30 years
What are the clinical features of MS?
Depends of area of demyelination
- loss of vision in one eye, double vision (optic neuritis)
- changes in sensation
- ataxia
- weakness
Initial recovery is common
What are the two types of MS disease?
Relapsing/remitting:
- different areas affected at different times
- partial/complete recovery in between
- increasing treatment options in this variant
Chronic/progressive
- cumulative damage
How is MS diagnosed?
Treated?
Diagnosis:
- clinical, lumbar puncture, MRI scan mainstay
Treatment:
- high dose steroids in acute relapse
- disease modifying drugs reduce relapses and slow progression of disability in relapsing remitting disease e.g. betaferon, glatiramer
Ongoing disease:
- rehabilitation and supportive care, specialist nurses
- support for independent living and for carers
What is Motor Neurone Disease?
List some clinical features:
MND - destruction of motor neurones - cause unknown
Clinical features:
- limb weakness
- swallowing problems
- respiratory muscle weakness
How is MND diagnosed?
Treatment?
Prognosis?
Diagnosis:
- clinical, neurophysiology
Treatment:
- medication - limited value
- mainly supportive - feeding tubes, mobility aids, couh assist, communication aids, high levels of care in later stages of illness
Prognosis - usually <5yrs so support from specialist nurse, neurologist, GP, palliative care for pt and family is required
