Neurology 1 Flashcards
condition that can cause severe intention tremor
MS
what might chorea in the face be a sign of
Huntingtons disease
excessive stratum activity due to dopaminergic drugs used to treat parkinsons
myoclonus
muscle jerks
dystonia
repetitive contractions lead to abnormal posture
- primary: born with it
- secondary: caused by pathology e.g. stroke
what is affected in foot drop that leads to abnormal gait
weakness in ankle dorsiflexion
- LMN lesion to lower limb
what is a pyramidal gait
toe dragging along floor when they walk, upper limbs flexed
- caused by UMN problem
how do people compensate for pyramidal gait
swing leg out at the hip
where is the lesion if a patient cannot perform heel to toe test
VERMIS of cerebellum
essential tremor
autosomal dominant inheritance
symmetrical
not seen at rest
how can dystonia be treated
botox / surgery
inheritance of Wilsons disease
autosomal recessive
inheritance of muscular dystrophy
X linked recessive
inheritance of myoclonic epilepsy with ragged red fibres
mitochondrial
when is a myopathic gait seen
proximal muscle weakness
features of juvenille myoclonic epilepsy
early morning seizures triggered by - sleep deprivation - flashing lights - alcohol
what is focal onset epilepsy associated with
hippocampal sclerosis
treatment of focal onset epilepsy
carbamazepine
features of absense seizures
common in children
starting into space/ subtle eyelid/body movements
tonic seizure
stiffening of muscles in back/arms/legs
atonic seizures
loss of muscle control causing collapse
clonic seizures
rhythmic jerking
