2022-08-17 08:26:01 A 33-year-old man with a history of multiple sclerosis is brought to the emergency department due to new-onset leg weakness, numbness, and urinary incontinence.
In the past, he has had several acute exacerbations of multiple sclerosis, causing vertigo, vision impairment, and upper
extremity weakness, all of which improved after glucocorticoid treatments. A year ago he stopped taking disease-modifying therapy due to severe adverse effects. His vital signs are within normal limits. Mental status and cranial nerve examination are normal. Muscle strength in the upper extremities is 5/5 and in the lower extremities is 3/5. Pinprick sensation is decreased below the nipple. Proprioception is decreased over both lower extremities. Babinski reflex is present bilaterally. Open / Comment

2022-08-16 21:26:01 Educational objective: Alcoholic cerebellar degeneration is caused by damage to the Purkinje cells of the cerebellar vermis. Manifestations typically include the slowly progressive onset of ambulation difficulties, including wide-based gait and postural instability. Truncal coordination (eg, tandem gait) is impaired, but limb coordination (eg, finger-nose test) is relatively intact. Open / Comment
