Iraqi Board Neurology common mistakes
Iraqi Board Neurology · Understand the traps and how to avoid them.
On EEG items, describing the record only in terms of 'epileptiform vs normal' and skipping the systematic sequence (background frequency and reactivity, symmetry, montage/field of each discharge, then the specific pattern name such as generalized 3 Hz spike-wave, temporal intermittent rhythmic delta, or PLEDs), then choosing an answer that names a syndrome rather than the pattern actually shown.
Candidates study epilepsy clinically and treat EEG as a visual-recognition test, so they pattern-match the first striking feature and stop. They also under-practise describing fields and montage logic, which are what the item is really testing.
What to do instead
Before answering, write a five-line read on the scratch sheet: (1) background frequency and reactivity, (2) symmetry and focal slowing, (3) each discharge's morphology, frequency, field and montage behaviour, (4) activation/state at the time, (5) pattern name. Only then look at the options. Drill 20 records this way, including normal variants (wicket spikes, 14-and-6 positive bursts, rhythmic mid-temporal theta) so you do not overcall them.
In EMG/NCS items, jumping straight to a diagnosis (for example 'axonal neuropathy') without first classifying the study: sensory vs motor, upper vs lower limb, which nerve, and whether the abnormality is conduction block/demyelination, axonal loss, or a myopathic pattern (short small polyphasic MUAPs with early recruitment).
Candidates memorise disease-level facts but not the stepwise electrodiagnostic algorithm, and they confuse 'reduced amplitude' with 'axonal' without checking conduction velocity, distal latency, and the presence of conduction block or temporal dispersion.
What to do instead
Build a one-page decision tree: abnormal SNAP only = sensory/ganglionopathy; abnormal CMAP with normal SNAP = motor axon or anterior horn; slowing with block = demyelinating; myopathic MUAPs with normal NCS = muscle. Practise with numbers, not pictures: given latency, amplitude and velocity, state the category before naming a disease.
In stroke items, choosing thrombolysis or thrombectomy based on the clinical syndrome alone, without explicitly checking and stating the time window, last-known-well time, contraindications (recent surgery, anticoagulation/INR, platelet count, blood pressure, prior haemorrhage), and imaging findings such as haemorrhage on non-contrast CT or large-vessel occlusion with salvageable penumbra.
The dramatic clinical story pulls attention, and candidates under-rehearse the checklist format. Time-window and contraindication details are also updated periodically, so older study material misleads them.
What to do instead
Answer every acute stroke item by writing the four gates first: last-known-well and window, contraindications, BP and glucose, imaging. Only then select the intervention. Re-verify current window and imaging-selection criteria from a current guideline summary rather than memory.
Treating 'seizure' and 'epilepsy' as interchangeable and defaulting to a single broad-spectrum antiseizure medication for every scenario, without classifying seizure type (focal vs generalized onset, aware vs impaired awareness, motor vs non-motor), identifying the epilepsy syndrome, and checking drug suitability for that syndrome (for example avoiding sodium-channel blockers in generalized epilepsies with myoclonic or absence features).
Candidates learn drugs by list rather than by indication matrix, and they do not practise the ILAE classification steps under time pressure, so they skip the classification that determines the correct answer.
What to do instead
For each epilepsy item, state seizure type, then syndrome, then first-line drug, then drugs to avoid, then counselling points (driving, pregnancy, adherence). Build a small table of narrow- vs broad-spectrum agents and the syndromes where each is contraindicated or preferred.
On headache items, diagnosing migraine or tension-type headache without first excluding red flags and secondary causes, and without applying explicit diagnostic criteria (attack duration, number of attacks, associated features, and the distinction between aura and non-aura).
Headache feels like a 'soft' domain, so candidates rely on gestalt. They also skip the secondary-headache screen because it feels like a separate topic, when the item often hinges on one red flag such as thunderclap onset, fever, papilloedema, or age over 50 with new headache.
What to do instead
Use a fixed two-step template: red flags first (SNOOP-type list), then formal criteria for the primary headache. For every headache vignette, write whether imaging or lumbar puncture is indicated and why. Learn the criteria verbatim enough to count attacks and duration.
In movement disorder items, describing tremor or parkinsonism vaguely ('rest tremor, rigidity') instead of separating the cardinal features and using the discriminating signs: true rest tremor with re-emergent component, bradykinesia with decrement, lead-pipe vs cogwheel rigidity, postural instability timing, asymmetry at onset, response to levodopa, and presence of atypical features (early falls, vertical supranuclear gaze palsy, autonomic failure, apraxia) that argue against Parkinson disease.
Candidates learn Parkinson disease as a single prototype and do not rehearse the atypical parkinsonism discriminators, so they cannot separate the options when the vignette deliberately includes one atypical feature.
What to do instead
For each vignette, list the positive and negative findings in a two-column table and ask specifically: is onset asymmetric, is tremor truly at rest, is there early postural instability, are there gaze or autonomic features? Match the feature pattern to the syndrome before choosing a drug or diagnosis.
In demyelinating disease items, answering from the clinical episode alone without applying dissemination in space and time, and without checking for red flags that argue against multiple sclerosis (age at onset, progressive course from onset, normal CSF with atypical features, systemic disease, or better explanation such as neuromyelitis optica spectrum disorder with longitudinally extensive cord lesion or optic neuritis with severe bilateral visual loss).
The classic 'young woman with optic neuritis' template dominates study, so atypical presentations are misclassified. Candidates also confuse attack treatment with disease-modifying therapy.
What to do instead
For each case, state dissemination in space and time explicitly, list the alternative diagnoses you excluded and the test that excluded each, then separate acute attack management from long-term prevention. Memorise the serological and imaging discriminators for MS vs NMOSD vs MOG antibody disease.
In neuroinfectious and tropical neurology items, choosing empiric antimicrobials without first committing to a syndrome and a diagnostic plan (CSF opening pressure, cell differential, protein, glucose ratio, Gram stain and culture, PCR, and when imaging must precede lumbar puncture), and ignoring regionally prevalent diseases and their specific exposures.
Candidates treat this domain as a list of organisms and skip the CSF interpretation framework, and they do not link exposure history (animal contact, water, ticks, travel, immunosuppression) to the differential.
What to do instead
Practise a CSF interpretation grid: bacterial vs viral vs tuberculous vs fungal vs autoimmune patterns, with expected opening pressure and glucose. For each vignette, state the syndrome, the top three organisms given the exposure, the first-line test, and the empiric regimen with the reason for each agent. Always state whether imaging is needed before lumbar puncture.
In pediatric neurology items, applying adult thresholds and adult disease prototypes to children, for example misclassifying a benign neonatal or febrile seizure as epilepsy, missing developmental milestones and age-specific examination norms, or forgetting age-dependent causes (metabolic disease, congenital infection, genetic syndromes) and the different dosing and contraindication profile in children.
Most adult-neurology study material is not age-stratified, so candidates carry adult frameworks into pediatric vignettes and do not check the developmental history that the item is built around.
What to do instead
For every pediatric item, first state the age and the expected milestone or examination norm at that age. Then classify the event as provoked vs unprovoked, and consider age-specific aetiologies in order (congenital, metabolic, genetic, infectious, traumatic). Keep a separate short list of pediatric-specific prescribing cautions.
In behavioural neurology and neuro-oncology items, choosing a diagnosis from the cognitive or imaging description without localising the lesion or naming the syndrome (for example failing to separate fluent vs non-fluent aphasia, to distinguish delirium from dementia, or to link a ring-enhancing lesion with oedema and mass effect to a differential that includes metastasis, high-grade glioma and abscess with the test that discriminates them).
Candidates treat these as vocabulary topics and do not practise lesion-to-syndrome mapping or the imaging-to-differential step, so they recognise the words but cannot apply them to a case.
What to do instead
For cognitive cases, state the affected domain, the bedside test that demonstrates it, and the anatomical correlate before choosing. For imaging descriptions, list the discriminating features (number, location, enhancement pattern, oedema, calcification, restricted diffusion) and the single next test. Rehearse a short aphasia and delirium-vs-dementia algorithm until it is automatic.
