motor function Flashcards
motor neuron disease: summarise the pathophysiology of motor neuron disease
what is motor neurone disease (MND)
progressive neurodegenerative disorder of motor system (spectrum of disorders) that takes out both upper and lower motor neurones; can be genetic or sporadic
example of a motor neurone disease (MND)
amyotrophic lateral sclerosis (ALS)
6 upper motor neurone signs of a motor neurone disease
increased muscle tone (spasticity of limbs and tongue), brisk limbs and jaw reflexes (hyper-reflexia), Babinski’s sign, loss of dexterity (dyspraxia), dysarthria (problem speaking), dysphagia
5 lower motor neurone signs of a motor neurone disease
weakness, muscle wasting, tongue fasciculations and wasting, nasal speech, dysphagia
when can motor neurone disease (MND) cause death
degeneration goes from distal to proximal; death when affects respiratory muscles
