Cerebellum & Atxia Flashcards
CP of Archi-Cerebellar Syndrome
CP of Neo-Cerebellar Syndrome
CP of Neo-Cerebellar Syndrome
- Disturbance of Integration of voluntary moter characterized by ….
CP of Neo-Cerebellar Syndrome
- Disturbance of compound movement:
- Asthenia (Usually subjective).
- Hypermetria and Hypometria.
- Decomposition of movement.
- Adiadochokinesia: Disturbance in patient’s ability to perform rapid alternative movements.
CP of Neo-Cerebellar Syndrome
- Disturbance of muscle tone:
Hypotonia
Def of Ataxia
- Incoordination of voluntary motor activity with or without disequilibrium in absence of
motor weakness.
Types of Ataxia
1) Cerebellar ataxia.
2) Sensory ataxia.
3) Vestibular ataxia.
4) Combined ataxia.
5) Hysterical ataxia.
Causes of Cerebellar Ataxia
- Heredofamilial (i.e. hereditary ataxia)
- Symptomatic
Causes of Cerebellar Ataxia
- Heredofamilial
Heredofamilial (i.e. hereditary ataxia)
- Friedreich’s ataxia.
- Marie’s ataxia.
Causes of Cerebellar Ataxia
- Symptomatic
CP in Friedrich’s Ataxia
Friedrich’s Ataxia is associated with …..
CP of Marie’s Ataxia
- Neo-cerebellar syndrome.
- Preservation of deep reflexes.
- Extensor planter response.
Marie’s Ataxia is associated with
- Ocular nerve palsies.
- Mental impairment.
- Extra-pyramidal syndromes.
INVx for Heredofamilial Ataxia
INVx for Heredofamilial Ataxia
- Non-Structural INVx
- deficiency diseases, metabolic disorders, genetic…etc.
INVx for Heredofamilial Ataxia
- Structural INVx
Brain CT:
* Cerebellar hematoma, Large mass.
Brain MRI:
* Demyelination, Infarction, Congenital… etc.
TTT of Heredofamilial Ataxia
- Physiotherary → For balance training.
- Specific treatments → In cases of well-known treatable causes.
- No specific pharmacotherapy → For hereditary ataxias.
Def of Sensory Ataxia
- It is due to interruption of the sensory pathways transmitting proprioceptive sensations.
