Neuro

A boards-focused map of stroke syndromes: anterior-circulation (ACA/MCA/PCA) cortical patterns and lacunar syndromes, the medial-vs-lateral "rule of 4" for crossed brainstem syndromes (Wallenberg, AICA, medial medullary, locked-in), and the acute CT-then-thrombolysis/thrombectomy management pathway.

A boards-focused walkthrough of seizures and epilepsy — from excitation/inhibition pathophysiology and 2017 ILAE classification through syndrome-specific semiology, EEG signatures, and first-line drugs, to first-seizure workup and status epilepticus next-best-step decisions.

A Step 2 CK-focused headache lesson that walks pathophysiology → pattern recognition → diagnosis → acute and preventive management for migraine, cluster, and tension-type headache, with red-flag vignettes and next-best-step decisions for dangerous secondary causes.

A boards-focused neurology lesson on dementia and neurodegenerative disease, moving from proteinopathy pathophysiology through pattern-based localization, comparison of the major dementias (Alzheimer, vascular, Lewy body, frontotemporal, NPH, prion), and the classic next-best-step decisions tested on Step 1 and Step 2 CK.

A Step 1 pairing of Parkinson and Huntington disease as opposite ends of the basal ganglia circuit — pathophysiology, TRAP vs chorea presentation, Lewy bodies vs caudate atrophy, and levodopa vs VMAT2-inhibitor management, with next-best-step vignette logic and a side-by-side comparison.

A high-yield STEP 1/CK lesson on multiple sclerosis and the CNS demyelinating differential — pathophysiology, localization buzzwords (optic neuritis, INO, Lhermitte, Uhthoff), McDonald/MRI/CSF diagnosis, and next-best-step management including the classic NMOSD interferon trap.

A high-yield boards lesson on peripheral neuropathy patterns and Guillain-Barré syndrome, moving from pathophysiology and localization through CSF/NCS diagnosis to the emergency management decisions (respiratory monitoring, IVIG vs plasma exchange, and the classic steroid trap). Includes a GBS-vs-CIDP comparison, Miller Fisher recognition, and real vignette buzzwords with next-best-step logic. Reviewed and corrected for clinical accuracy: the myelin image was changed from a CNS oligodendrocyte to a Schwann-cell (peripheral) diagram to match GBS localization.

A board-focused walk through myasthenia gravis and Lambert–Eaton syndrome — pathophysiology (postsynaptic AChR vs presynaptic P/Q-type Ca²⁺ channel), the use-dependent weakness discriminator, antibody and electrodiagnostic diagnosis, tumor associations (thymoma vs small cell lung cancer), and next-best-step management including myasthenic crisis. Anchored by vignettes, a comparison table, and legitimate memory hooks.
