Thiamine deficiency from chronic alcohol use can cause Wernicke’s encephalopathy, which is classically marked by ocular motor abnormalities and gait ataxia. The statement describing paralysis of the eye muscles along with ataxia best fits this condition because eye movement problems (ophthalmoplegia or nerve palsies affecting the ocular muscles) together with impaired coordination are the hallmark features you’d expect to see in this scenario. The other options don’t specifically align with this syndrome: nausea and vomiting, abdominal pain, or dyspnea can appear in many conditions but are not characteristic signs of thiamine deficiency presenting with ocular symptoms and ataxia. Remember that this deficit arises because thiamine is essential for brain energy metabolism; in alcohol users, stores are depleted, leading to dysfunction in brain regions that control eye movements and balance. Prompt thiamine treatment is important to prevent progression.
