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.
Apraxia of speech can be either acquired or present from birth. Acquired apraxia is due to damage in parts of the brain that are used for speech production, and the causes of apraxia from birth are not clear. Some symptoms of apraxia are: Distortion of sounds (such as vowels) Inconsistent errors in speech; Errors in tone, stress, or rhythm ...
Ideomotor Apraxia, often IMA, is a neurological disorder characterized by the inability to correctly imitate hand gestures and voluntarily mime tool use, e.g. pretend ...
Individuals with developmental verbal apraxia encounter difficulty saying sounds, syllables, and words. The difficulties are not due to weakness of muscles, but rather on coordination between the brain and the specific parts of the body. [2] [3] Apraxia of speech is the acquired form of this disorder caused by brain injury, stroke or dementia.
