Other Movement Disorders Flashcards
define tremor
involuntary, rhythmic, oscillating movements
is tremor hyperkinetic or hypokinetic
hyperkinetic
what kind of tremor occurs when the body is relaxed and supported by gravity
rest tremor
name the two types of action tremors
kinetic and postural
what kind of tremor would be seen in someone trying to complete a finger-to-nose test?
intention tremor (type of kinetic)
what kind of tremor is seen with someone that occurs when the walk forward?
task-specific tremor
what descriptors are important in determining phenomenology of a tremor (5 things)
location laterality frequency amplitude situation in which it occurs
what is an essential tremor?
postural + kinetic
are men or women more likely to develop head tremors?
women
epidemiology of essential tremor
bimodal age onset
5% of population
no gender preference
what tremor improves with alcohol
essential tremor
does essential tremor have increased mortality?
no, but 2-4 times the risk of developing parkinson’s
treatment of essential temor
reduce caffeine
sleep
propanolol 40mg BID (can titrate up to 320mg)
Primadone 12.5- 25mg (can titrate up to 250mg)
define dystonia
sustained of intermittent muscle contractions causing twitching postures, repetitive movements, or both.
difference between the movements in dystonia vs chorea or myoclonus
longer in duration, patterned
treatment of dystonia
chemodenervation, oral medications (dopaminergics, anticholinergics, dopamine depleting, muscle relaxants), and deep brain stimulation
define tic
brief, stereotyped movement or vocalization
3 key features of a tic
urge
relief
suppressible
when does a tic not always warrant a work up
in children- can be transient
define Tourette’s
multiple motor tics
at least one vocal tic
starts before age 21
occurs at least daily for at least one year
list of drugs we have to know for hyperkinetic movement disorders (from the neuro section drug list, just an FYI)
Ropinirole Levodopa Risperidone Olanzepine Propranolol
Rx treatment for tics
risperidone
olanzepine
in restless leg syndrome what does U.R.G.E. stand for
urge
rest (makes worse)
getting active (makes better)
evening (makes worse)
what are the physical exam findings with restless leg syndrome
none, it is normal
what are the common secondary causes of restless leg syndrome
pregnancy, iron deficiency, peripheral neuropathy, ESRD, chronic lung disease, gastric surgery, parkinson’s
what is the primary cause of restless leg syndrome
unknown,
more common in elderly
genetic probably (3-5 times higher risk with a 1st degree relative)
treatment of restless leg syndrome
iron
dopamine agonist
off-label drugs (gabapentin, levodopa, pregabalin, opiates, benzos, topiramate)
what is wilson’s disease
rare, autosomal recessive disorder
50% present with movement disorder
50% present with liver disease
fatal if untreated
