Czech Neurology Board Examination common mistakes
Czech Neurology Board Examination · Understand the traps and how to avoid them.
When asked to localise a lesion, the candidate names a single anatomical structure without first walking through a systematic localisation algorithm (which level: muscle, nerve, plexus, root, cord, brainstem, hemisphere), so a lesion at the conus medullaris is attributed to a peripheral nerve or a cortical lesion is placed in the brainstem.
Czech neurology training heavily rewards pattern recognition from classic textbook syndromes, and candidates memorise syndromes as labels rather than as derivations. Under time pressure the label arrives before the reasoning, and the step where the level of the lesion is established gets skipped entirely.
What to do instead
Before answering any localisation question, write the localising signs you have extracted (which muscles, which reflex, which sensory level, which cranial nerve) and explicitly state the level that explains all of them, then the level that would be excluded. Practise by taking ten case vignettes and forcing yourself to name the level and the two alternative levels before the diagnosis.
On vascular-territory questions, the candidate attributes a syndrome to the wrong artery because they match on a single prominent sign (for example assigning any hemiparesis with aphasia to the middle cerebral artery, or any crossed cranial nerve sign to the posterior inferior cerebellar artery) without checking the full constellation.
Territory syndromes are taught with a few flagship features, and candidates remember the flagship rather than the discriminating features. The classic 'crossed signs' mnemonic is over-applied, so lateral medullary and lateral pontine syndromes are conflated, and MCA versus internal carotid versus anterior choroidal distinctions are lost.
What to do instead
Build a one-page table of territories with columns for the discriminating feature that separates it from its nearest neighbour (for example, lateral medullary versus lateral pontine: which cranial nerve nuclei, presence of Horner, pattern of ataxia, hearing). Recite the discriminating column, not the flagship signs, when revising.
In epilepsy questions, the candidate classifies a seizure by its most dramatic motor feature and then selects a drug from that label, ignoring the distinction between focal and generalised onset, the presence of structural lesion, age, sex and childbearing potential, and comorbidity.
Semiology is visually memorable while classification and pharmacology are abstract, so the motor picture dominates recall. Candidates also default to the drug most recently studied rather than the drug matched to the syndrome, and they forget that the same semiology can arise from focal or generalised onset.
What to do instead
For every seizure question, state three things before choosing treatment: onset (focal, generalised, unknown), syndrome if identifiable, and patient-specific constraints (sex, pregnancy plans, renal or hepatic function, interaction risk). Learn one first-line and one contraindication per syndrome rather than a drug list per seizure type.
On nerve conduction and EMG interpretation, the candidate reads a single abnormal number (for example a prolonged distal latency) and declares demyelination, without checking whether the abnormality is in the appropriate range for demyelination, whether it is uniform or non-uniform, whether amplitude loss explains the slowing, and whether the finding is technically artefactual.
Electrodiagnostic criteria are numerical and candidates memorise thresholds without the logic of how they interact. Temperature, age, height and technical factors shift values, and candidates do not routinely apply the correction factors, so borderline values are over-read.
What to do instead
Adopt a fixed reading order for every study: temperature and technical adequacy, then sensory before motor, then amplitude before conduction velocity, then the pattern of abnormality (axonal versus demyelinating versus mixed), then the distribution (mononeuropathy, mononeuropathy multiplex, length-dependent polyneuropathy). State the pattern before the diagnosis.
In headache questions, the candidate diagnoses migraine or cluster headache from the severity of pain alone and does not apply the full criteria count, nor do they screen for red flags (thunderclap onset, new onset after 50, fever, focal deficit, papilloedema, positional character, change in established pattern).
Headache is treated as a low-stakes topic during preparation, so criteria are skimmed. Candidates also fear missing a secondary headache and over-diagnose it, or fear over-investigating and under-diagnose it, without a structured screening approach.
What to do instead
Memorise the criteria counts as numbers (for example how many attacks, how long untreated, how many of the pain characteristics, how many associated symptoms) and recite them. For every headache vignette, explicitly list which red flags are present or absent before naming a primary headache.
On movement disorder questions, the candidate labels any tremor or any rigidity as Parkinson's disease and does not test the discriminating features: true rest tremor versus postural, asymmetry, response to dopaminergic therapy, presence of atypical features (early falls, early dementia, autonomic failure, vertical gaze palsy, alien limb), and drug-induced causes.
Parkinson's disease is the archetype taught first and most, so it becomes the default answer. Atypical parkinsonian syndromes are taught later and in less detail, and candidates do not have a checklist for the features that argue against Parkinson's disease.
What to do instead
Keep a short 'against Parkinson's disease' list and apply it to every parkinsonism vignette: early falls, early dementia, symmetry at onset, poor levodopa response, autonomic failure, supranuclear gaze palsy, cerebellar signs, alien limb. Also always check the drug history for dopamine antagonists before diagnosing a neurodegenerative cause.
In demyelinating disease questions, the candidate diagnoses multiple sclerosis on the basis of a single clinical event plus nonspecific white matter lesions, without applying dissemination in space and time criteria, without excluding mimics (neuromyelitis optica spectrum disorder, MOG antibody disease, small vessel disease, vasculitis, sarcoidosis, infection), and without checking the antibody status where it changes management.
The imaging appearance of white matter lesions is over-weighted relative to the clinical and temporal criteria, and the diagnostic criteria are remembered as a general idea rather than as countable requirements. Candidates also do not habitually consider the antibody-mediated mimics.
What to do instead
For every demyelination vignette, write out the dissemination in space count and the dissemination in time evidence separately, then list the mimic most likely given the specific features (optic neuritis with severe visual loss and poor recovery suggests aquaporin-4; conus involvement suggests aquaporin-4; MOG has different optic neuritis features). Practise counting criteria rather than recognising pictures.
In neuro-oncology and neuroinfection questions, the candidate answers with the diagnosis but omits the urgent management step or the diagnostic test that must come first (for example, naming a tumour without addressing steroid use and seizure prophylaxis, or naming bacterial meningitis without stating that blood cultures and lumbar puncture timing and the decision to give antibiotics before imaging are the actual question).
Candidates revise diseases as facts rather than as clinical pathways, so the recall stops at the name. Emergency management sequences are learned separately and are not integrated with the disease list.
What to do instead
For each high-yield emergency (meningitis, encephalitis, raised intracranial pressure, spinal cord compression, status epilepticus, acute stroke with thrombolysis decision), memorise a fixed ordered sequence of actions with the timing attached, and rehearse the sequence aloud. In any question, answer the pathway, not just the diagnosis.
On neurorehabilitation and neuropsychology questions, the candidate answers with a general principle ('early rehabilitation is beneficial', 'the patient needs cognitive rehabilitation') instead of naming the specific deficit, the specific assessment, the specific intervention and the realistic prognostic expectation, and they conflate delirium, depression and dementia.
These domains feel less 'testable' than acute neurology, so preparation is superficial. Candidates also underestimate how often the question asks about prognosis, capacity, or the difference between treatable and irreversible cognitive impairment.
What to do instead
Learn a small set of named scales and what each measures, and for each major deficit (aphasia, neglect, executive dysfunction, depression after stroke) know one assessment and one evidence-based intervention. Always distinguish delirium (acute, fluctuating, attention) from depression (mood, anhedonia, reversible) from dementia (progressive, multiple domains) explicitly in the answer.
On legal, ethical and organisational questions, the candidate answers from personal moral intuition rather than from the legal framework: they misapply informed consent and capacity assessment, they do not know the rules on driving and epilepsy or on reporting, they confuse the roles of the patient's wishes, the family's wishes and the statutory decision-maker, and they do not know the framework for end-of-life decisions and palliative sedation.
These topics are perceived as common sense and are skipped in revision. The legal framework is jurisdiction-specific and candidates assume their intuition matches the statute, which it often does not.
What to do instead
Learn the specific Czech legal rules for capacity, informed consent, refusal of treatment, advance directives, driving restrictions in epilepsy and other neurological conditions, and reporting obligations, and for each learn the one question that tests it. Answer with the legal test (for example, does the patient understand, retain, weigh and communicate the decision) rather than with a conclusion.
