Ataxia vs. Apraxia

Ataxianoun

(pathology) Lack of coordination while performing voluntary movements, which may appear to be clumsiness, inaccuracy, or instability.

Ataxianoun

(chemistry) The condition of a polymer in which the orientation of the subunits is random

Ataxianoun

(obsolete) Disorder; irregularity.

Ataxianoun

Disorder; irregularity.

Ataxianoun

Irregularity in disease, or in the functions.

Ataxianoun

Loss of coordination in the voluntary muscles, especially the limbs; an inability to coordinate voluntary muscle movements; it results in unsteady movements and a staggering gait. See also locomotor ataxia, an ataxia which occurs when attempting to perform coordinated muscular movements.

Ataxianoun

inability to coordinate voluntary muscle movements; unsteady movements and staggering gait

Ataxianoun

the loss of full control of bodily movements.

Ataxia

Ataxia 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. Ataxia is a clinical manifestation indicating dysfunction of the parts of the nervous system that coordinate movement, such as the cerebellum.

Apraxianoun

(neurology) Total or partial loss of the ability to perform coordinated movements or manipulate objects in the absence of motor or sensory impairment; specifically, a disorder of motor planning.

Apraxianoun

inability to make purposeful movements, but without paralysis or loss of sensory function.

Apraxianoun

inability to make purposeful movements

Apraxianoun

inability to perform particular purposive actions, as a result of brain damage

Apraxia

Apraxia is a motor disorder caused by damage to the brain (specifically the posterior parietal cortex or corpus callosum) which causes difficulty with motor planning to perform tasks or movements. The nature of the damage determines the disorder's severity, and the absence of sensory loss or paralysis helps to explain the level of difficulty.
