✍️ Sample NCS Questions & Answers
1. What are the signs of increased intracranial pressure?
Rising ICP requires urgent intervention to prevent brain herniation.
2. Which characteristic distinguishes peripheral vestibular nystagmus from central vestibular nystagmus?
Peripheral vestibular nystagmus is direction-fixed (fast phase does not change direction with gaze) and is suppressed by visual fixation, distinguishing it from central causes.
3. What is multiple sclerosis?
MS damages the myelin sheath around nerve fibers, disrupting signal transmission and causing diverse symptoms.
4. Which neurotransmitter imbalance is primarily implicated in the pathophysiology of schizophrenia?
The dopamine hypothesis of schizophrenia posits that the positive symptoms of the disorder, such as hallucinations and delusions, are primarily associated with excessive dopamine activity in certain brain regions. Antipsychotic medications, the cornerstone of treatment, primarily work by blocking dopamine D2 receptors. While other neurotransmitters are involved, dopamine dysregulation remains a central focus in understanding and treating schizophrenia.
5. Ketamine's analgesic mechanism in chronic pain states primarily involves:
Ketamine blocks NMDA receptors, interrupting the glutamate-driven central sensitization and wind-up that perpetuate chronic pain states.
6. A patient with refractory chronic migraine is being considered for occipital nerve stimulation (ONS). What is the theoretical basis for its analgesic effect?
ONS modulates the trigeminocervical complex where occipital afferents converge with trigeminal pain signals, reducing migraine pain through neuromodulation.
