Movement Disorders (Hon) Flashcards
What are the 5 Akinetic Rigid Syndrome discussed in lecture?
AKA Bradykinetic (slow and stiff)
1. Parkinson’s Disease
2. Progressive Supranuclear Palsy (PSP)
3. Multiple Systems Atrophy (MSA)
4. Cortical Basal Degeneration (CBD)
5. Lewy body Disease
Pathophysiology of Idiopathic Parkinson’s Disease
depletion of dopamine in the nigrostriatal system; disrupts the balance of dopamine and acetylcholine (decreased inhibitor of the inhibitor (GABA) doesn’t allow for movement to occur)
What are the 3 cardinal features of Parkinson’s disease?
Tremor - resting tremor “pill-rolling”
Rigidity - increased resistance “cogwheel”
Bradykinesia -slowness of movement and difficulty initiating movement
Myerson’s sign
repetitive tapping on the forehead leads to sustained blink response - if present then, can indicate Parkinson’s disease
Progressive Supranuclear Palsy (PSP)
a Akinetic Rigid Syndrome; patients are slow and stiff; there will also be loss of voluntary control of eye movements (especially the vertical gaze)
Loss of vertical gaze is seen in which akinetic rigid syndrome?
Progressive Supranuclear Palsy (PSP)
Multiple Systems Atrophy (MSA)
AKA Shy-Drager Syndrome
a Akinetic Rigid Syndrome; PRONOUNCED autonomic dysfunction will be observed
Cortical Basal Degeneration (CBD)
a Akinetic Rigid Syndrome
characterized by both cortical and basal ganglionic dysfunction; may also see cortical sensory loss, apraxia, myoclonus or aphasia
Anti-Parkinsonian treatment
Dopamine agonists (Bromocriptine)
Levodopa
COMT inhibitors
Anticholinergics
Deep Brain Stimulation
In which akinetic rigid syndrome will you see PRONOUNCED autonomic dysfunction early and dramatically in the disease?
Multiple Systems Atrophy (MSA)
Chorea
irregular, brief “dance-like” movements
Athetosis
writhing, sinuous movements (often occur in combination with chorea)
Dystonia
sustained muscle contractions that produce twisting and repetitive movements and abnormal postures
Ballism
large amplitude, flinging movement; usually from the proximal extremities (hips and shoulders)
Tic
brief, rapid, repetitive, seemingly purposeless stereotyped action that may involve single or multiple muscle groups
