Degenerative and Neuromuscular Disease Walkthrough

Upper lesion: the cord loses cortical control. Expect spasticity, brisk reflexes, clonus and a positive Babinski sign . Bulk is kept early; any wasting is late, from disuse.
Lower lesion: the muscle loses its nerve. Expect flaccid tone, weak or absent reflexes, early wasting and fasciculations .

Trace the motor relay from cortex to muscle, localize the lesion from the bedside exam, watch FVC fall while oxygen saturation hides the danger, and follow Parkinson disease, multiple sclerosis, myasthenia gravis, Guillain-Barré syndrome, ALS and dementia through the nursing decisions that matter. Go at your own pace. Nothing here is graded.
