A neurological disease refers to any ailment of the central nervous system, including abnormalities of the brain, spinal cord and other connecting nerve fibres. [8] Where millions of people are affected by neurological diseases on a worldwide scale, [8] it has been identified that the number of different types of neurological diseases exceeds six hundred, [9] any of which an individual can incur.
Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is an autosomal recessive late-onset heredodegenerative multisystem neurological disease. The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present.
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 ]
A study using upright MRI found cerebellar tonsillar ectopia in 23% of adults with headache from motor-vehicle-accident head trauma. Upright MRI was more than twice as sensitive as standard MRI, likely because gravity affects cerebellar position. [22] Cases of congenital Chiari malformation may be explained by evolutionary and genetic factors.
Post-viral cerebellar ataxia also known as acute cerebellitis and acute cerebellar ataxia (ACA) is a disease characterized by the sudden onset of ataxia following a viral infection. [1] The disease affects the function or structure of the cerebellum region in the brain.
Spinocerebellar ataxia type 6 (SCA6) is a rare, late-onset, autosomal dominant disorder, which, like other types of SCA, is characterized by dysarthria, oculomotor disorders, peripheral neuropathy, and ataxia of the gait, stance, and limbs due to cerebellar dysfunction. Unlike other types, SCA 6 is not fatal.
Gillespie syndrome, also called aniridia, cerebellar ataxia and mental deficiency, [1] [2] [3] is a rare genetic disorder. The disorder is characterized by partial aniridia (meaning that part of the iris is missing), ataxia (motor and coordination problems), and, in most cases, intellectual disability .
Usually, individuals with this condition have cerebellar ataxia, areflexia, high-arched feet, optic nerve wasting/degeneration, sensorineural deafness. [5]These symptoms have variable onset, but they generally begin episodically after having a fever-causing infection such as the common cold, manifesting mainly as sudden-onset ataxic episodes and encephalopathy.
