Too many to answer. The spinocerebellar ataxias (sca) are inherited conditions with ataxia & other symptoms. I believe that nearly 60 different scas currently identified. The different scas involve different genes and have different symptoms. Some may look parkinsonian. Sca-17 has prominent dementia without knowing which sca, this question is impossible to answer. A local movement disorder neurologist can help you.
Part of the problem. There are different types of spino-cerebellar ataxia syndromes. Many of them have involvement of the autonomic nervous system producing problems with the normal function of many organs in the thorax, abdomen and pelvix, beside changes if the muscle tone and coordination. Genetic studies will determine the specific type. Thanks.
Surely. Classic model is Freidrich's ataxia, associated with scoliosis, cardiomyopathy, retinitis pigments, hearing loss, and cataracts. Another disorder. Olivopontocerebellar ataxia might cause autonomic issues, such as orthostatic hypertension. So, yes, we do encounter systemic associations with many of these disorders.
Archaic term and. Not used in academic settings due to confused terminology. Was used to describe both hereditary and sporadic neurodegenerative ataxias, but now classify these based on genetic and molecular markers. Amongst these, friedreich's ataxia, ataxia telangiectasia, sca 1-7, mitochondrial. Ataxia is incoordination of movement due to cerebellar dysfunction.
Variety of causes... The causes of spinocerebellar ataxia span several pages, but can be categorized as: hereditary, infectious, medication-related, alcohol-related, traumatic, vitamin deficiency related, etc. The start of an evaluation for ataxia includes a detailed neurological exam by a movement disorder specialist and a brain MRI to see whether the cerebellum is indeed shrinking.
17 people at least. Since there are probably at least 17 varieties of spinocerebellar ataxia (of which friedreich's is the most famous) 17 discoverers (or more) probably exist. Why does this matter?
Generic comments. Spinocerebellar ataxias are hereditary conditions, which may have features of Multiple Sclerosis, Parkinson's disease, and even blend into pernicious anemia signs.. Other disorders can indeed be confused with SCA's. However, most neurologists can skillfully sort out characteristics, and provide definitive conclusive testing to arrive at correct diagnosis.
Usually not similar. Motor neuron disease and spinocerebellar ataxia (sca) are very different diseases. The former affects motor neurons that control voluntary muscle activity, while the latter are a group (nearly 60 different ones currently) of disease that are progressive, degenerative, and affect coordination. Sca-36 does have ataxia in combination with motor neuron disease, but this is the exception not the rule.
Unsteadiness. Ataxia causes unsteadiness and falls can occur.
Many ways. Spinocerebellar ataxia (sca) is rare. There are many types of sca described. Some have mild symptoms with imbalance, numbness and clumsiness. Other types can lead to major disability. You doctor can run some test to determine the type of sca. Check http://neuromuscular. Wustl. Edu/ataxia/domatax. Html for updated information.
Unfortunately no. Unfortunately, there is no cure for spinocerebellar ataxia. Rehabilitation programs help people maintain function as the disease progresses.
