Children may be born with apraxia; its cause is unknown, and symptoms are usually noticed in the early stages of development. Apraxia occurring later in life, known as acquired apraxia, is typically caused by traumatic brain injury, stroke, dementia, Alzheimer's disease, brain tumor, or other neurodegenerative disorders.

Constructional apraxia is common after right parietal stroke and it continues after visuospatial symptoms have subsided. [5] Patients with posterior and parietal lobe lesions tend to have the most severe symptoms. [9] In Alzheimer's disease research, the AT8 antibody has proven to be an early indicator of tau protein pathology.
Developmental verbal dyspraxia (DVD), also known as childhood apraxia of speech (CAS) and developmental apraxia of speech (DAS), [3] [4] is an inability to utilize motor planning to perform movements necessary for speech during a child's language learning process. Although the causes differ between AOS and DVD, the main characteristics and ...
Apraxia of speech (AOS) is a neurological disorder that affects the brain pathways involved in planning the sequence of movements involved in producing speech. Source: ITV, The Diary Of A CEO ...
An example is commissural disconnect in adults which usually results from surgical intervention, tumor, or interruption of the blood supply to the corpus callosum or the immediately adjacent structures. Callosal disconnection syndrome is characterized by left ideomotor apraxia and left-hand agraphia and/or tactile anomia, and is relatively rare.
Ideomotor apraxia is hypothesized to result from a disruption of the system that relates stored tool use and gesture information with the state of the body to produce the proper motor output. This system is thought to be related to the areas of the brain most often seen to be damaged when ideomotor apraxia is present: the left parietal lobe and ...
Ideational apraxia is a condition in which an individual is unable to plan movements related to interaction with objects, because they have lost the perception of the object's purpose. [2] Characteristics of this disorder include a disturbance in the concept of the sequential organization of voluntary actions.
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]
