A detailed understanding of neuroanotomy, although useful in precisely localizing
lesions, pinpointing d iagnoses, and i mpress i n g/bori ng colleagues
during rounds, is not required to make basic differentials. The simplest method is
to sta rt at the m uscle and work bock anatom ica lly to the cerebral cortex.
Examples of on anatomic differential for "weakness" are in parentheses:
1 . Muscle ( polymyositis)
2 . Neuromuscular j unction ( myasthenia gravis)
3 . Peripheral nerve (Guillain-Barre)
4. Nerve plexus (brachial amyotrophy)
5 . Nerve root (disc herniation)
6. Meninges/subarachnoid space (arachnoiditis)
7. Spinal cord (spinal cord tumor)
8. Brainstem ( pontine infarction)
9. Subcortical structures - basal ganglia, thalamus (lacunar infarction - internal
capsule)
1 0. Cortical structu res - cerebr u m , cerebellum ( m iddle cerebral a rtery
i nfarction
