dementias and movement disorders Flashcards
Binswanger’s disease - type of dementia
Small vessel vascular dementia
Binswanger’s disease symptoms
4 Ds - Dementia, dysexecutive synd, delay (slow), depletion (apathy and amotivation)
Binswanger’s disease MRI
periventricular white matter abnormalities
Vascular dementia
4 Ds - Dementia, dysexecutive synd, delay (slow), depletion (apathy and amotivation)
Binswanger’s disease
Tauopathies
Alzheimer, FTD, CBD, PSP
alpha-synuclinopathies
Parkinson’s, MSA, lewy body dementia
Alzheimer’s pathology
Neuritic plaques, neurofibrillary tangles
Donepezil treats? Function? side effects
Alzheimer’s
cholinesterase inhib
insomnia, muscle cramp
Galantamine treats? Function? side effects
Alzheimer’s
cholinesterase inhib
wt loss, avoid with bad liver/kidney
Rivastigmine treats? Function, side effects
Alzheimers and Parkinson’s dementia
cholinesterase inhib
minimal - no liver mtab, no drug intxn
Memantine tx, function, side effects
Alzheimers
NMDA antagonist
Few side effects or interactions
Lewy body dementia sx
Fluctuating cognition
visual hallucinations
parkinsonism (after cognitive)
Parkinson’s disease DA agonists
Ropinirole
Pramipexole
Rotigotine
Apomorphine
Corticobasal degeneration sx
- L-dopa unresponsive parkinsonism
- alien hand
- asymmetric limb dystonia, apraxia, myoclonus, neglect, cortical sensory loss
- FT type dementia
Corticobasal degen imagine
asymmetric cortical atrophy
PSP sx
Axial rigidity dysphagia early falls vertical (esp down) gaze palsy FT type dementia
PSP imaging
Midbrain atrophy (hummingbird sign)
MSA sx
Parkinsonism and/or cbl dysfxn
severe autonomic dysfxn
MSA imaging
“hot cross bun”
Dopa-responsive dystonia sx
Twisted foot, gait abnormality worse in evening poss parkinsonism child/young adult very responsive low dose L-dopa
Wilson’s disease gene & inheritance
Gene ATP7B copper transporter
AD
Wilson’s disease dx
Dysarthria, gait change
tremor, dystonia, parkinsonism
psych disease, dementia
Wilson’s disease imaging
T2 hyper, T1 hypo basal ganglia
Wilson’s disease labs
24hr urine copper high, ceruloplasmin low
Wilson’s disease treatments
Penicillamine
trientine
zinc
Huntington’s gene
CAG trinuc repeat huntingtin gene, chr 4
Huntington’s sx
Hyperkinetic mvt (chorea, myoclonus)
Poor voluntary mvt (dex, slurred speech)
Difficulty swallowing, falls
Subcortical cognitive - loss speed and flexibility
Huntington’s tx
Tetrabenazine (only helps hyperkinetic mvts)
Ataxia telangiectasia gene
ATM, chr 11. Immune!
Ataxia telangiectasia sx
Ataxia
tiny red spidery veins (esp face), dilated vessels eyes
Frequent sinopulmonary infxns
Ataxia telangiectasia labs
increased AFP, CEA
Decreased Ig G, A, E
Neuroacanthocytosis sx
lip/tongue biting –> oral “eating’ dystonia, tics, chorea
akinetic/rigid feet
vertical ophthalmophegia
