You are babysitting a 7-year-old child with a known history of seizure activity. You notice they appear flushed and seem unresponsive. You ask if they are feeling alright and they stare at you blankly. After a few seconds they act as if nothing happened and return to play. Is this a generalized or focal seizure? Based upon this description, what specific type of seizure did this individual experience? - Answer generalized absence seizure Describe the importance of brain activity that occurs during REM sleep. - Answer During this phase of sleep, incoming sensory input is blocked; the brain cannot process it. However, internalized sensory tracts are stimulated allowing previously formed memories to replay in one's mind. Studies have shown that adequate time spent in REM sleep is necessary for normal physiologic and psychologic functioning during periods of wakefulness. A patient reports to the emergency department where you are working at 7 pm. They report that earlier that morning they began to experience numbness in their right leg. They had walked more than usual the day before, so they ignored their symptoms. As the day went on, they noticed that the numbness got worse, and they began to slur their words. By the time they are evaluated, their symptoms begin to subside. The numbness disappears, and their speech returns to normal. What do you suspect this patient has experienced? What is the clinical significance? - Answer This patient has experienced a TIA as their symptoms subsided in less than 24 hours without intervention. However, this should not be ignored as TIAs serve as a warning sign that a stroke can occur in the future. Underlying pathology such as atherosclerosis, etc. must be addressed for prevention.

A 75-year-old male is brought to the emergency department by their spouse at 8 pm. The spouse reports that they were cleaning up after dinner at approximately 6:30 pm, and she noticed that her husband's speech was very unclear. When she asked him what was going on, he said that he didn't know and that the entire right side of his face felt numb. She reports that he is very active, but he has a past medical history of atrial fibrillation. Based upon these symptoms and past medical history, what do you suspect this patient is experiencing? How would you confirm this diagnosis? What treatment should be administered? Explain why you chose that treatment. - Answer This patient is more than likely experiencing an ischemic stroke. A CT scan and MRI would be needed to determine if a clot was blocking blood flow to the brain tissue and to rule out a hemorrhagic stroke. If a clot is found, this patient should receive tPA drugs as they are within the 3-4.5 hour treatment window. A patient is being seen in your office with a primary complaint of daytime fatigue that has lasted for the past 2 months. They go on to tell you that they are having difficulty with work performance and are constantly on edge. You suspect they have chronic insomnia. What are the 4 primary symptoms of insomnia? Describe a nonpharmacologic treatment plan that you can prescribe for this patient. - Answer The 4 primary symptoms of insomnia are: Difficulty initiating sleep Difficulty maintaining sleep Waking up too early Chronic nonrestorative or poor sleep You would educate the patient on proper sleep hygiene and encourage them to evaluate possible stressors that may need to be removed from their daily routine. Sleep hygiene involves the establishment of consistent sleep patterns (going to bed at the same time each night and only sleeping as long as one needs to feel refreshed during the day), creating a comfortable sleeping environment (optimal room temperature), avoidance of screens and excessive light right before bed, and finally, avoidance of stimulants (caffeine) several hours prior to normal bedtime.
