Truncal ataxia (or trunk ataxia) is a wide-based "drunken sailor" gait characterized by uncertain starts and stops, lateral deviations and unequal steps. It is an instability of the trunk and often seen during sitting. [2]

The differential diagnosis of sporadic ataxia cases that include truncal ataxia can be complicated, given the wide variety of diseases and conditions that present with similar symptoms: chronic alcohol use, exposure to toxic agents, immune-mediated inflammation (paraneoplastic cerebellar degeneration, anti-glutamic acid decarboxylase antibodies ...

For example, damage to midline cerebellar structures usually presents with gait and truncal ataxia, while damage to the unilateral cerebellar hemisphere usually causes ipsilateral cerebellar ataxia. Understanding this neuroanatomy and correlation to …

Truncal ataxia. Patients may present with truncal instability in the form of oscillation of the body while sitting (worse with arms stretched out in front) or standing (titubation). Limb ataxia. Limb ataxia is often used to describe ataxia of the upper limbs resulting from incoordination and tremor and can be better described by functional ...

2016年8月8日 · Grade 2-3 ataxia was 92.9% sensitive and 61.1% specific to detect AICA/PICA stroke in patients with AVS, with 100% sensitivity to detect AICA stroke. In turn, two signs (nystagmus of central origin and grade 2-3 Ataxia) had 100% sensitivity and 61.1% specificity.

The primary symptoms consist of progressive truncal ataxia, oculo-cutaneous teleangectasias, polyneuropathy, hypotonia and oculomotor apraxia. Teleangectasia is more frequently localized on the conjunctivae but is also found in ear lobes and the popliteal fossa (Fig. 6 ).

We found acute truncal ataxia-without nystagmus-in 15% (n = 14) of our overall cohort. Lesions involved stroke syndromes affecting the posterior inferior cerebellar artery, anterior inferior cerebellar artery, and superior cerebellar artery, thalamic stroke, cerebral hemisphere stroke, multiple sclerosis, and a cerebellar tumour.

Cayman cerebellar ataxia (ATCAY) is an autosomal recessive neurologic disorder characterized by hypotonia from birth, variable psychomotor retardation, and cerebellar dysfunction, including nystagmus, intention tremor, dysarthria, ataxic gait, and truncal ataxia.

Truncal instability and tremor of the body or head may occur, especially with cerebellar midline disorders. 1 Ataxia can arise from disorders that involve cerebellum, spinal cord, brain stem, vestibular nuclei, thalamic nuclei, cerebral white matter, cortex (especially frontal), and …

2023年2月23日 · Ataxia is impaired coordination in the absence of weakness. Acute ataxia is a neurological emergency, and vascular lesions of the cerebellum (infarction, hemorrhage) must be considered/ excluded. Causes. Acute onset (minutes/ hours) cerebellar hemorrhage or infarction (particularly suspect this if hemiataxia or other brainstem signs)
