Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

YEAR 2 SYSTEMS REVIEW - NEUROLOGY

YEAR 2 | PAGE 50C - LOCALIZE -> TIME COURSE -> VASCULAR / ELECTRICAL / INFLAMMATORY / DEGENERATIVE -> TEST -> THERAPY

NEURO SPINE: DEFICIT -> ANATOMIC LEVEL + SIDE -> TRACT / TERRITORY -> TEMPO -> MECHANISM -> CT / MRI / EEG / CSF / EMG AS APPROPRIATE -> THERAPY. DO NOT LET A FAMILIAR DISEASE NAME REPLACE LOCALIZATION. G. NEUROLOGY CLOSED-BOOK REVIEW MAP

LANE	MUST RETRIEVE WITHOUT NOTES	HIGH-DISCRIMINATION TRANSFER
Localization	Cortex/subcortex, brainstem, cord, root/plexus, peripheral nerve, NMJ, muscle; UMN vs LMN; cranial nerves and crossing logic.	Name level + side before disease; predict associated findings that should travel with the lesion.
Stroke / acute neuro	Vascular territories, ischemic vs hemorrhagic pattern, imaging sequence concepts, edema/herniation and emergency priorities.	Use focal deficit + time course + territory; instability/emergency findings change sequencing.
Seizure / headache	Focal vs generalized semiology; provoked vs unprovoked; status; primary headache vs SAH/meningitis/mass/ICP red flags.	Classify the syndrome and danger state before picking an antiseizure or headache drug.
Movement / demyelination	Parkinson, essential tremor, Huntington, cerebellar syndromes; MS vs peripheral demyelination.	Use movement phenotype, localizing signs and MRI/CSF context rather than one association.
NMJ / neurodegeneration	MG vs Lambert-Eaton vs botulism; neuropathy vs myopathy; Alzheimer/Lewy body/FTD/vascular/prion tempo and domains.	Reflexes, sensation, fatigability, autonomics, cognition domain and tempo are decisive discriminators.

H. TOP 10 MOST-MISSED SYSTEM CONCEPTS - #6 TO #8

# / CONCEPT	DEEP EXPLANATION	WHY STUDENTS MISS IT	EASIEST CLUE
6. Localization before diagnosis	A neurologic syndrome becomes tractable when you first decide central vs peripheral, then level, side and pathway/territory. Disease names are downstream of anatomy.	Recognizable labels such as stroke, MS or neuropathy tempt learners to skip the anatomic proof.	Ask where is the lesion? and predict one companion finding before naming the disease.
7. Crossing determines the side of the deficit	Motor, dorsal-column and spinothalamic pathways cross at different levels; brainstem lesions can produce crossed cranial-nerve/long-tract patterns.	Students remember pathway names but not the exact decussation level.	Trace receptor -> first neuron -> crossing -> destination; then place the lesion relative to the crossing.
8. Tempo is a neurologic diagnostic test	Seconds-to-minutes suggests vascular/electrical processes; hours-days may fit inflammatory/infectious/toxic; weeks-months can suggest mass/degenerative processes, though exceptions exist.	Learners focus on symptom content and ignore the time course that reshapes pretest probability.	After localization, ask how fast did it evolve? before choosing the mechanism.

SCHOOL-EXAM GATE	BOARD / COMLEX TRANSFER
• Localize an unfamiliar lesion before disease naming. • Interpret vascular territory, seizure/headache danger and neuromuscular pattern.	• Integrate neuroanatomy + pathology + pharmacology. • Explain side/crossing logic, not just buzzwords.
• Use imaging/EEG/CSF/EMG conceptually as confirmatory tools. 2026/27 systems-review expanded edition - align with school objectives and verify official exam updates before testing	• Use timed mixed cases with CT/MRI-style patterns and emergency sequencing.
