Which symptom is characteristic of Parkinson's disease?
Resting tremor
Intention tremor
Chorea
Hemiballismus
Parkinson's disease involves dopaminergic neuron loss leading to a resting tremor, typically seen when the limb is at rest. Intention tremor is associated with cerebellar dysfunction, chorea with basal ganglia disorders like Huntington's, and hemiballismus with subthalamic nucleus lesions.
Multiple sclerosis is primarily characterized by which pathological process in the central nervous system?
Demyelination of neurons
Axonal degeneration of peripheral nerves
Neurotransmitter excess
Amyloid plaque deposition
Multiple sclerosis is an autoimmune condition that targets myelin in the central nervous system, leading to demyelination. Peripheral nerve axonal degeneration occurs in conditions like Guillain-Barré syndrome, and amyloid plaques are seen in Alzheimer's disease.
What is the most common acute presentation of an ischemic stroke?
Sudden onset unilateral weakness
Gradual bilateral numbness
Progressive memory loss
Intermittent headaches
Ischemic strokes often present suddenly with focal neurological deficits, most commonly unilateral weakness due to interrupted blood flow. Gradual symptoms, memory loss, or intermittent headaches are less typical for an acute ischemic event.
Which of the following best defines epilepsy?
Recurrent unprovoked seizures
Headaches with aura
Transient ischemic attacks
Progressive muscle weakness
Epilepsy is defined by recurrent, unprovoked seizures due to abnormal electrical activity in the brain. Headaches with aura describe migraines, TIAs are transient ischemic events, and progressive muscle weakness suggests neuromuscular disorders.
Which symptom is most typical of a migraine headache?
Throbbing unilateral headache with photophobia
Sharp bilateral headache worsened by coughing
Band-like constriction headache
Headache relieved by lying down
Migraines typically present as throbbing, unilateral headaches accompanied by photophobia and sometimes aura. A band-like constriction is characteristic of tension headaches, and headaches worsened by coughing or relieved by lying down suggest other etiologies.
A lesion in the internal capsule affecting the corticospinal tract typically results in which clinical sign?
Contralateral spastic paralysis
Ipsilateral flaccid paralysis
Bilateral lower limb weakness
Generalized muscle atrophy
The corticospinal tract decussates at the medullary pyramids, so a lesion in the internal capsule causes contralateral upper motor neuron signs like spastic paralysis. Ipsilateral flaccid paralysis suggests peripheral nerve injury, and muscle atrophy develops over time with LMN lesions.
Which clinical finding most strongly suggests a lower motor neuron lesion rather than an upper motor neuron lesion?
Fasciculations
Spasticity
Hyperreflexia
Extensor plantar response
Fasciculations represent spontaneous muscle fiber twitches and are characteristic of lower motor neuron damage. Spasticity, hyperreflexia, and an extensor plantar response (Babinski sign) are features of upper motor neuron lesions.
What is considered the most effective first-line pharmacological treatment for motor symptoms in Parkinson's disease?
Levodopa/carbidopa
Selegiline
Amantadine
Bromocriptine
Levodopa combined with carbidopa remains the most effective therapy for improving motor symptoms in Parkinson's disease by replenishing central dopamine. Other agents like selegiline, amantadine, and dopamine agonists are used adjunctively or when symptoms are mild.
Which concept is central to the McDonald criteria for the diagnosis of multiple sclerosis?
Dissemination in time and space of CNS lesions
Presence of peripheral demyelinating lesions
Elevated amyloid in CSF
Positive anti-dsDNA antibodies
The McDonald criteria require evidence that demyelinating lesions are separated in both time and space within the central nervous system. Peripheral lesions and CSF amyloid or anti-dsDNA antibodies are unrelated to multiple sclerosis.
Which class of medication is commonly used for abortive (acute) treatment of migraine headaches?
Serotonin 5-HT1B/1D agonists (triptans)
Beta-blockers
Calcium channel blockers
Statins
Triptans are serotonin 5-HT1B/1D receptor agonists that constrict intracranial blood vessels and inhibit trigeminal nerve activation, making them effective acute migraine treatments. Beta-blockers and calcium channel blockers are used prophylactically, and statins have no role in migraine management.
Which clinical feature helps differentiate essential tremor from Parkinsonian tremor?
Improvement with small amounts of alcohol
Resting tremor
Rapid fatigue of tremor with movement
Presence of rigidity
Essential tremor often improves transiently with small amounts of alcohol, whereas Parkinsonian tremor is typically a resting tremor with associated rigidity. Rapid fatigue and rigidity are more characteristic of Parkinson's disease.
A patient cannot raise their eyebrow or wrinkle their forehead on one side but has normal limb strength. Which diagnosis is most likely?
Bell's palsy (facial nerve palsy)
Middle cerebral artery stroke
Myasthenia gravis
Lambert-Eaton syndrome
Bell's palsy, a facial nerve (VII) lower motor neuron lesion, causes paralysis of both the upper and lower face on one side. In a central stroke, the forehead often remains unaffected due to bilateral cortical innervation. Myasthenia gravis and Lambert-Eaton syndrome typically present with muscle weakness rather than isolated facial paralysis.
A lesion in Broca's area of the dominant hemisphere would most likely result in which clinical finding?
Non-fluent expressive aphasia
Fluent but nonsensical speech
Loss of comprehension
Loss of visual fields
Broca's area is responsible for speech production, so damage leads to non-fluent expressive aphasia with relatively preserved comprehension. Fluent nonsensical speech (Wernicke's aphasia) and impaired comprehension are seen with Wernicke's area lesions. Visual field loss is not a language deficit.
Which of these is a significant pharmacokinetic concern when prescribing carbamazepine for seizure control?
Hepatic enzyme induction causing drug interactions
Renal excretion without metabolism
Narrow therapeutic index unaffected by other drugs
Primarily excreted in bile unchanged
Carbamazepine induces cytochrome P450 enzymes, increasing the metabolism of itself and other drugs, leading to complex interactions. It is metabolized hepatically and has a narrow therapeutic index; it is not excreted unchanged in bile or solely by the kidneys.
Huntington's disease is characterized by degeneration of which brain structure leading to choreiform movements?
Caudate nucleus
Substantia nigra
Cerebellar vermis
Anterior horn cells
Huntington's disease involves selective degeneration of neurons in the caudate nucleus and putamen, leading to chorea and psychiatric manifestations. The substantia nigra is primarily affected in Parkinson's disease, the cerebellar vermis in certain ataxias, and anterior horn cells in motor neuron diseases like poliomyelitis.
Which finding helps distinguish amyotrophic lateral sclerosis (ALS) from a peripheral neuropathy?
Preserved sensory nerve conduction studies
Presence of decreased reflexes
Marked distal sensory loss
Elevated cerebrospinal fluid protein
ALS affects upper and lower motor neurons without sensory involvement, so sensory nerve conduction remains normal. Decreased reflexes and sensory loss suggest peripheral neuropathy, and elevated CSF protein is common in Guillain-Barré syndrome.
In Lambert-Eaton myasthenic syndrome, repetitive nerve stimulation typically shows which electromyography (EMG) finding?
Incremental increase in amplitude with high-frequency stimulation
Decremental response with low-frequency stimulation
Normal responses at all frequencies
Fibrillation potentials at rest
Lambert-Eaton syndrome involves impaired presynaptic calcium channels leading to low initial amplitude that increases (facilitation) on high-frequency stimulation. A decremental response at low frequency is characteristic of myasthenia gravis, while fibrillations indicate denervation.
Which antibody is most specific for neuromyelitis optica spectrum disorder when differentiating it from multiple sclerosis?
Anti - aquaporin-4
Anti - myelin basic protein
Anti - AQP1
Anti - demyelinating glycoprotein
Anti - aquaporin-4 antibodies (NMO-IgG) are highly specific for neuromyelitis optica and help differentiate it from multiple sclerosis. Antibodies to myelin basic protein or other glycoproteins are not specific markers for NMO.
Which type of nystagmus is most suggestive of a central cause of vertigo rather than a peripheral vestibular disorder?
Direction-changing gaze-evoked nystagmus
Unidirectional horizontal nystagmus
Rotary torsional nystagmus
Peripheral positional nystagmus
Direction-changing gaze-evoked nystagmus suggests central pathology, as the fast component changes direction with gaze. Peripheral vestibular disorders typically produce unidirectional horizontal nystagmus that is suppressed by visual fixation.
A hemisection lesion (Brown-Séquard syndrome) at T10 on the left side would result in which pattern of sensory and motor loss?
Ipsilateral motor paralysis and contralateral loss of pain and temperature below T10
Ipsilateral loss of pain/temperature and contralateral motor paralysis below T10
Bilateral loss of proprioception only
Contralateral loss of all modalities below T10
Brown-Séquard syndrome causes ipsilateral upper motor neuron signs (motor paralysis) due to corticospinal tract disruption and contralateral pain/temperature loss beginning a few segments below the lesion due to spinothalamic decussation. Proprioception is lost ipsilaterally, not bilaterally.
