Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system [1] and is characterized by poor articulation of phonemes. [2] It is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words.
Occlusion of AICA is considered rare, but generally results in a lateral pontine syndrome, also known as AICA syndrome.The symptoms include sudden onset of vertigo, vomiting, nystagmus, dysarthria, falling to the side of the lesion (due to damage to vestibular nuclei), and a variety of same-side features including hemiataxia, loss of all types of sensation of the face (due to damage to the ...

Dysarthria is a motor speech disorder caused by damage to the central and/or peripheral nervous system, and it is related to degenerative neurological diseases, such as Parkinson's disease, cerebrovascular accident (CVA), and traumatic brain injury (TBI). [13]
Arteries of the brain. Anterior cerebral artery labeled at the left (twice) The anterior cerebral artery is divided into 5 segments. Its smaller branches: the callosal (supracallosal) arteries are considered to be the A4 and A5 segments. [1] [2] A1 originates from the internal carotid artery and extends to the anterior communicating artery (AComm).
Unlike the topographic maps of the senses, the neurons of the motor cortex are efferent neurons that exit the brain instead of bringing information to the brain through afferent connections. The motor system is responsible for initiating voluntary or planned movements ( reflexes are mediated at the spinal cord level, so movements associated ...

Flaccid dysarthria is a motor speech disorder resulting from damage to peripheral nervous system (cranial or spinal nerves) or lower motor neuron system. Depending on which nerves are damaged, flaccid dysarthria affects respiration, phonation, resonance, and articulation. It also causes weakness, hypotonia (low-muscle tone), and diminished ...
