neural and neuromuscular diseases Flashcards
primary muscle disorders
dystrophy
myotonia
myasthenia
myositis
muscular dystrophies
1) progressively degenerative diseases of skeletal muscle
2) basic disorder is within the muscle fiber
- nerves and neuromuscular junctions are normal
3) no dystrophin
- sarcomere unstable
- cell death
- fat and fibrous replace
- eventually spreads and fatal
myotonia
?
myasthnia
1) weakness
2) Neuromuscular transmission at the level of the NMJ via fault in Ach
3) autoantibodies
4) associated with thymoma
myositis
1) multiple etiology
2) metaplasia
3) trauma
trauma
1) concussion
2) contusion
- coup
- contrecoup
3) hematomas
- epi
- sub
- intraparenchymal
4) plegias
- C4
5) quad, hemi, para
cerebral palsy
1) spastic most common
2) 50% cognitive impairment
3) non progressive motor deficits with paralysis and spastic movements
4) degree of severity is dependent ?
cerebrovascular injuries
1) hypoxia
- seconds changes to neuron, mins irreversible brain damage
2) stroke
- hypertension, diabetes, atherosclerosis, hypercholesterolemia are risk factors
3) types of infarction
- hemorrhagic
- non hemorrhagic
- anticoagulation medications
demyelinating
1) neurologic inflammatory conditions
2) activated immune cells invade CNS
2) myelin sheath is resorbed
4) charcots triad
- intention tremor
- nystagmus
- dysarthria
Alzheimers
1) sporadic > familial
2) autopsy finds amyloid plaques and neurofibrillary tangles
degenerative
1) parkinsons disease
2) extrapyramidal diorders/show extrapyramidal features
2) automatic sensorimotor integration
3) chief pathologic change is depigmentation of substantia nigra (dopamine)
amyotrophic lateral sclerosis
1) affect motor neurons
2) muscle weakness and atrophy
3) bunina bodies
4) salivation, dysphonia, dysphagia, dysarthria
infections
1) meningitis
- bacterial
- dura, arachnoid, pia
2) encephalitis
- viral
- parenchyma
3) spongiform encephalopathies
- prion, spongiform change
- creutzfeld jakob
- bovine spongiform encephalopathy
epilesy
1) generalized
- motor (unconscious, tonal clonic, aura)
- non motor (consciousness, absent, repeated movement)
2) gingival hyperplasia
- phenytoin
- carbamezepine
neuralgic pain
1) paroxymal pain extending along the course of one or more sensory nerves
2) artery compression
3) cluster headaches, blood shot eyes, lacrimation, nasal congestion
