Ataxia with Oculomotor Apraxia Type 1 and Type 2 (AOA1 and AOA2) have also been identified. What is Sporadic Ataxia? There is a large group of people who have symptoms of Ataxia that usually begin in adulthood and who have no known family history of the disease.
Ataxia with oculomotor apraxia is a condition characterized by progressive problems with movement. The hallmark of this condition is difficulty coordinating movements (ataxia), which is often the first symptom. Most affected people also have oculomotor apraxia, which makes it difficult to move their eyes side-to-side.
Recessive Spastic Ataxias. Spastic ataxias are ataxias that have spasticity (muscle stiffness) in addition to ataxia. Some types of spastic ataxias are dominant and some are recessive. The recessive forms are described below. The acronym SPAX is used to name some of these ataxias (SPastic AtaXia).
Dominant Spinocerebellar Ataxias (SCA) There are many different types of Spinocerebellar Ataxia (SCA). These ataxias are all characterized by autosomal dominant inheritance. The primary feature of these disorders is ataxia (problems with balance, speech, and eye movements).
The word “ataxia” can also be used to describe a symptom of incoordination which can be associated with infections, injuries, other diseases, or degenerative changes in the central nervous system. This form of ataxia is different from the neurological disease.
Autosomal recessive spastic ataxia of Charlevoix-Saguenay, more commonly known as ARSACS, is a condition affecting muscle movement. People with ARSACS typically have abnormal tensing of the muscles (spasticity), difficulty coordinating movements (ataxia), muscle wasting (amyotrophy), involuntary eye movements (nystagmus), and speech difficulties (dysarthria).
