15. Clinical Approach to Movement Disorders Flashcards
What type of movement disorder is aka Akinetic Rigid Syndromes, which is MC parkinsons disease but encompasses idiopathic parkinson disease, postencephalitic, toxin induced (MC= carbon monoxide), drug induced (neuroleptics- haldol/prochlorperazine) and MPTP (meperidine) induce parkinsons symptoms?
Bradykinetic Disorders (lewy body dementia is a type)
What disease is caused by depletion of dopamine in the nigrostriatal system, disrupting the balance of dopamine and acetylcholine, asso w Cardinal findings= tremor (resting unilateral/pill rolling), rigidity (inc resistance to movement/cogwheel rigidity), and bradykinesia (slowness of movement-cant initiate movement)?
Idiopathic Parkinson’s Disease
Sx if Rx dont work= deep brain stimulation MC*
other common features of Idiopathic Parkinson’s Disease is postural instability, hypophonia, hypomimia (masked facies), decreased frequency of eye blink, myerson’s sign (tap on forehead leads to sustained blink), gait disturbance (festinating), dyautonomia (othostatic hypotension**MC, incontinence, impotence and anhydrosis) and many will develop?
Dementia
What akinetic rigid syndrome is assoc with bradykinesia and rigidity along with loss of voluntary control of eye movements (vertical gaze)- such that involuntary is intact (dr moving head) but voluntary when following finger- typically cannot look DOWN**?
Progressive Supranuclear Palsy PSP
What akinetic rigid syndrome is associated with bradykinesia and rigidity along with *pronounced autonomic dysfunction?
Multiple System Atrophy MSA (shy-drager syndrome)
What akinetic rigid syndrome is characterized by both cortical and basal ganglionic dysfunction, bradykinesia, rigidity, and may also see cortical sensory loss, apraxia, myoclonus or aphasia?
Cortical Basal (ganglionic) degeneration CBD
No treatment exists for akinetic rigid syndromes besides anti-parkinson tx - which do not work-but still try
Hyperkinestic movement disorders are associated with chorea (irregular brief dancelike movements), athetosis (writhing, sinuous movements), dystonia (muscle contractions that produce twisting and repetitive movements), ballism (large amplitude, flinging movement from proximal extremity) and tic which is what?
breif rapid repetitive, purposeless stereotyped action
What disease has gradual onset and progression of chorea and dementia by inherited trinucleotide repeat gene defect on chr 4, AD inhereitance, sx start ages 30-50 with lifespan of 15yrs after onset sx, genetic testing for dx, no known cure?
Huntington’s Disease
**Psych symptoms first
What type of chorea occurs mainly in children and adolescents as a complication of a previous infection with group A hemolytic strep, may be a form of arteritis, characterized by unilat choreiform movements which can be confused for restlessness/fidgeting, also see behavior changes- tx=bedrest and antibiotics?
Syndenham’s Chorea
What type of dystonia is characterized by dystonic movements and postures without other signs, may be inherited as AD, AR, or Xlinked recessive disorder, whose onset may be in childhood or later in life but remains throughout life?
Idiopathic Torsion Dystonia
Idiopathic Torsion Dystonia is associated with torticollis, blepharospasm (closure of eyelid), oromandibular dystonia (spasm muscle around mouth), arm may be help hyperpronated with wrist flexed and fingers extended, leg may be help in extension with pronation and?
inversion of the foot
Idiopathic Torsion Dystonia is treated with Carbamazepine, anticholinergics, benzodiazepines, neuroleptic drugs, baclofen, and what drug which is tried FIRST?
low doses of Levodopa
What type of dystonia has dystonia confined to a FOCAL AREA, associated with ONLY ONE OF THE FOLLOWING: blepharospasm, oromandibular dystonia, spasmodic torticollis, writers cramp, used same meds as idiopathic torsion dystonia but BOTOX** is treatment of choice to weaken muscles in this focal disease?
Focal Torsion Dystonia
EMG needle guidance to see most active muscle for injection with BOTOX
What is an AR disorder of copper metabolism that produces neurologic and hepatic dysfunction localized to chr13 (ATP7B gene), decreased binding of copper to ceruloplasmin leading to large amount of free copper deposited into tissues- presents in childhood or young adult life?
Wilson’s Disease
Wilson’s Disease has both bradykinetic and hyperkinetic** (imp) features, including resting or postural tremor, choreiform movements, rigidity, bradykinesia, dyarthria, dysphagia, ataxia, personality/behavioral changes, dementia and psychosis or?
