Ataxia (from Greek α- [a negative prefix] + -τάξις [order] = "lack of order") is a neurological sign consisting of lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, and abnormalities in eye movements, that indicates dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum.
As a stand-alone condition, "ataxia is a degenerative disease of the nervous system," explains Andrew Rosen, chief executive officer of the National Ataxia Foundation. There are many types ...
Cerebellar ataxia is a form of ataxia originating in the cerebellum. [1] Non-progressive congenital ataxia (NPCA) is a classical presentation of cerebral ataxias. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. [ 2 ]
Ataxia in the upper and lower extremities at onset or at full development, asymmetric distribution of sensory loss, sensory loss not being restricted to the lower limbs (as in length dependent axonal polyneuropathy) are specific to sensory neuronopathies. [4]
Dysmetria of the extremities caused by hemispheric syndromes is manifested in multiple ways: dysrhythmic tapping of hands and feet and dysdiadochokinesis, which is the impairment of alternating movements. [5] Damage to the cerebellum makes a person slow to orient their extremities in space. [7] Motor control as a learning process
Hemiparesis or hemiplegia of the contralateral upper and lower extremities* [2] Sensory loss of the contralateral face, arm and leg* [2] Ataxia of contralateral extremities* [1] Speech impairments/aphasia: Broca's area, Wernicke's or Global aphasia as a result of a dominant hemisphere lesion (usually the left brain) [1] [2] [3]
As a result of this gait impairment, falling is a concern in patients with ataxia. [3] Truncal ataxia affects the muscles closer to the body such as the trunk, shoulder girdle and hip girdle. It is involved in gait stability. [3] Truncal ataxia is different from appendicular ataxia. Appendicular ataxia affects the movements of the arms and legs.
