OBJECTIVE To identify the genetic cause of a syndrome causing cerebellar ataxia and eye movement abnormalities. METHODS We identified 2 families with cerebellar ataxia, eye movement abnormalities, and global developmental delay. We performed genetic analyses including single nucleotide polymorphism genotyping, linkage analysis, array comparative genomic hybridization, quantitative PCR, and Sa...
1. The cerebellum has long been known to participate in movement control. One of the enduring theories of cerebellar function is that it "tunes" and coordinates sensorimotor traffic in other parts of the CNS. In particular, it has been implicated in the control of the sensitivity of muscle spindle stretch receptors through the fusimotor system. 2. The stretch sensitivity of spindle primary endi...
Abstract Background Cogan’s anterior internuclear ophthalmoplegia (INO) is characterized by INO with inability to converge and commonly thought be due rostral midbrain lesion. A lesion outside that causes unilateral combined upgaze palsy ataxia are rarely described. Case presentation 67-year old male presented left (INO), appendicular bilateral palsy. Magnetic Resonance Imaging (MRI) Angiograph...
BACKGROUND We describe the clinical characteristics of a Swedish family with autosomal dominant cerebellar ataxia, sensory and autonomic neuropathy, additional neurological features and unknown genetic cause. METHODS Fourteen affected family members were identified. Their disorder was characterized by neurological examination, MRI, electroneurography, electromyography, MIBG-scintigraphy, and ...
In October, 2012, a 37-year-old Rwandan businessman was transferred to our hospital from Nairobi, Kenya, where he had been investigated for subacute onset of progressive cerebellar ataxia and quadriparesis of unclear cause. He presented initially to a hospital in Nairobi in August, 2012, with a 2–3 week history of imbalance and weakness, as well as back pain and stiff ness, without cognitive or...
The cerebellar glucose metabolism of multiple system atrophy with predominant cerebellar ataxia (MSA-C) is known to be decreased but is not defined among areas of cerebellum. We encountered a 54-year-old man who developed dizziness and progressive ataxia followed by urinary incontinence and orthostatic hypotension, all of those symptoms progressed relentlessly and the symptoms responded poorly ...
IMPORTANCE Cerebellar ataxias are a diverse collection of neurologic disorders with causes ranging from common acquired etiologies to rare genetic conditions. Numerous genetic disorders have been associated with chronic progressive ataxia and this consequently presents a diagnostic challenge for the clinician regarding how to approach and prioritize genetic testing in patients with such clinica...
