Neuro: Cerebelar and Basal Ganglia disorders Flashcards
Cerebellar of Basal Ganglia Disorder?
asynergia
cerebellar pathology
the loss of ability to associate muscles together for complex movements
Cerebellar of Basal Ganglia Disorder?
resting tremor
basal ganglia disorder
an involuntary, rhythmic, oscillatory movement observed at rest
Cerebellar of Basal Ganglia Disorder?
Ataxic Gait
cerebellar disorder
Wide - based gait, uncoordinated gait, clumsy and unsteady, zigzag gait
Cerebellar of Basal Ganglia Disorder?
Choreoathetosis
basal ganglia disorder
both chorea & athetosis: slow, involuntary, writhing, twisting, “worm-like” movements (UE>LE & neck, face, tongue, trunk) combined with involuntary, rapid, irregular and jerky movt’s
Cerebellar of Basal Ganglia Disorder?
hypotonia
cerebellar disorder
Decreased in tone (resistance to passive movement), DTR’s normal
Cerebellar of Basal Ganglia Disorder?
Dyssynergia
Cerebellar disorders
Inability to associate muscles together for complex movements
Cerebellar of Basal Ganglia Disorder?
chorea
Basal ganglia disorder
involuntary, rapid, irregular and jerky movt’s
Cerebellar of Basal Ganglia Disorder?
Bradykinesia
basal ganglia disorder
-decreased amplitude and velocity of voluntary movement
Cerebellar of Basal Ganglia Disorder?
akinesia
basal ganglia disorder
inability to initiate movement
Cerebellar of Basal Ganglia Disorder?
rebound phenomenon
cerebellar pathology
is the loss of the check reflex, or check factor, which functions to halt forceful active movements when resistance is eliminated
Cerebellar of Basal Ganglia Disorder?
Dysdiadochokinesia
cerebellar disorder
Inability to perform rapid, alternating supination pronation movements.
unable to stop ongoing movement
Cerebellar of Basal Ganglia Disorder?
Dysmetria
cerebellar disorder
Underestimation or overestimation of necessary movement toward a target
Cerebellar of Basal Ganglia Disorder?
Nystagmus
cerebellar pathology
is a rhythmic, quick, oscillatory, back-and-forth movement of the eyes
Cerebellar of Basal Ganglia Disorder?
Ataxia
Cerebellar disorder
Voluntary movement is clumsy & uncoordinated
Cerebellar of Basal Ganglia Disorder?
asthenia
is generalized muscle weakness associated with cerebellar lesions
