Q

The most objective finding suggestive of an infection in the CSF analysis is:
a. Decreased protein
b. Increased protein
c. Decreased sugar
d. Pleocytosis
e. Turbidity

A

d. Pleocytosis

Pleocytosis refers to an increased number of cells in the cerebrospinal fluid (CSF), specifically an increase in white blood cells (WBCs). In the context of CSF analysis, pleocytosis is a strong indicator of an inflammatory response, including an infection in the central nervous system.
Other findings, such as changes in protein levels, sugar levels, or turbidity, can also be observed in CSF analysis during an infection, but pleocytosis is considered the most reliable and objective indicator in this context.

Destruction of the Medulla is NOT
manifested as:
a. Absent gag reflex
b. Irreversible apnea
c. Presence of agonal gaps
d. Presence of cough reflex

A

d. Presence of cough reflex

a. Absent gag reflex: The medulla is responsible for coordinating the gag reflex, so its destruction would typically result in the absence of the gag reflex.
b. Irreversible apnea: The medulla plays a crucial role in regulating breathing. Destruction of the medulla can lead to the loss of the respiratory centers, resulting in irreversible apnea (cessation of breathing).
c. Presence of agonal gaps: Agonal gaps are abnormal, irregular gasps or pauses in breathing that occur in the final moments before death. These can be a manifestation of medullary dysfunction or damage.
d. Presence of cough reflex: The cough reflex is primarily mediated by the medulla, and its destruction would typically result in the loss or absence of the cough reflex.

Q

Not casually related to development of PD:
a. Living in rural areas
b. Consumption of caffeine
c. Drinking of water from the well
d. Exposure to pesticides

A

b. Consumption of caffeine

b. Consumption of Caffeine - consumption of caffeine has actually been associated with a lower risk of developing Parkinson’s disease (PD). Several studies have suggested a potential protective effect of caffeine in reducing the risk of PD. However, it’s important to note that the exact mechanisms underlying this association are not fully understood.

a. Living in rural areas: There is some evidence to suggest that individuals living in rural areas may have a slightly higher risk of developing Parkinson’s disease. This could be due to increased exposure to certain environmental factors, such as pesticides or well water contaminated with toxins.

c. Drinking water from the well: The presence of certain toxins or contaminants in well water has been associated with an increased risk of Parkinson’s disease. Well water can sometimes
contain substances like manganese or other chemicals that may have neurotoxic effects.

d. Exposure to pesticides: Pesticide exposure has been identified as a potential risk factor for Parkinson’s disease. Certain pesticides, such as rotenone and paraquat, have been linked to an increased risk of developing the condition.

Q

Dementia is associated with deficiency of:
a. Folic Acid
b. Vitamin B12
c. Vitamin B1
d. Vitamin B6

A

b. Vitamin B12

A deficiency in vitamin B12 can lead to neurological symptoms, including cognitive impairment, memory loss, confusion, and even mood disturbances. It is particularly important to ensure adequate vitamin B12 intake, as it plays a crucial role in maintaining the health of the nervous system.

While deficiencies in other B vitamins, such as folic acid (a) and vitamin B6 (d), can also have an impact on neurological health, vitamin B12 deficiency is specifically associated with an increased risk of dementia.

Vitamin B1 deficiency is associated with another condition called Wernicke-Korsakoff syndrome, which can cause cognitive impairment but is not considered a direct cause of dementia.

b. Weakness: Weakness is the reduction in muscle strength and is a common positive motor symptom in peripheral nervous system diseases.

c. Calf Pain: While pain is not strictly a motor symptom, it is included in the list. Calf pain can be present in certain peripheral nerve disorders and is considered a positive symptom.

d. Hypertrophy: Hypertrophy refers to an increase in the size of muscle tissue and is not typically considered a positive motor symptom in peripheral nervous system diseases. It is more commonly associated with conditions such as muscle overuse or specific types of muscle disorders.

e. Muscle Cramps: Muscle cramps are involuntary and painful contractions of muscles. They are considered a positive motor symptom as they involve abnormal muscle activity.

b. Respiratory muscles usually spared
c. Associated most predominantly with calcium channel abnormality
d. Arms usually weaker than legs
e. Affects males more than females

A

c. Associated most predominantly with calcium channel abnormality

assoc with mutations in genes encoding sodium channels

Hypokalemic periodic paralysis (HPP) is a rare genetic disorder characterized by episodes of muscle weakness or paralysis caused by low levels of potassium in the blood

a. Onset of weakness usually before 25 years of age: This is true for hypokalemic periodic paralysis. The episodes of weakness typically begin in childhood or adolescence.

b. Respiratory muscles usually spared: This is generally true for hypokalemic periodic paralysis. During episodes of weakness, respiratory muscles are typically not affected, and breathing remains unaffected.

c. Associated most predominantly with calcium channel abnormality: This statement is not true. Hypokalemic periodic paralysis is primarily associated with mutations in genes encoding sodium channels, particularly the SCN4A gene. It is not predominantly associated with calcium channel abnormalities.

d. Arms usually weaker than legs: This is often observed in hypokalemic periodic paralysis. During an episode, the muscles of the arms are typically more affected than the muscles of the legs.

e. Affects males more than females: This is generally true for hypokalemic periodic paralysis. The condition is more commonly seen in males than females.

71
Q

A patient who is brain dead will NOT
manifest these:
a. (+) pupillary light reflex
b. (+) flexion withdrawal
c. Absent corneal reflex
d. Absent cough reflex

A

a. (+) pupillary light reflex

When a patient is determined to be brain dead, it means that there is complete and irreversible loss of all brain function, including the brainstem. As a result, certain reflexes and responses that rely on brainstem activity will be absent.

The Pupillary Light Reflex, which involves constriction of the pupils in response to light, is mediated by the brainstem. In a brain-dead patient, this reflex will be absent, and the pupils will not constrict when exposed to light.

75
Q

For corneal reflex, which are FALSE?
a. Has good prognostic value
b. (+) shows intact pontine function
c. May be elicited in both awake and comatose patients
d. (+) shows intact medullary brainstem function

A

d. (+) shows intact medullary brainstem function

a. Has good prognostic value: The corneal reflex can have prognostic value in certain clinical situations, such as coma or brainstem injury. Its absence or loss can indicate dysfunction or damage within the brainstem or cranial nerve V (trigeminal nerve).

b. (+) shows intact pontine function: This statement is false. The corneal reflex primarily involves the trigeminal nerve (cranial nerve V) and its connection with the facial nerve (cranial nerve VII). It is mediated by the brainstem, specifically the trigeminal sensory nucleus and the facial motor nucleus, which are located in the pons. Therefore, a positive corneal reflex does not specifically indicate intact pontine function but rather functioning of the brainstem structures involved.

c. May be elicited in both awake and comatose patients: The corneal reflex can be elicited in both awake and comatose patients, as long as the sensory and motor pathways involved in the reflex arc are intact. It does not rely on the patient’s level of consciousness.

d. (+) shows intact medullary brainstem function:
This statement is true. The corneal reflex involves the sensory input from the cornea traveling via the trigeminal nerve to the sensory nucleus of the trigeminal nerve, which is located in the pons. The motor output for the blink response is transmitted via the facial nerve, originating from the facial motor nucleus in the pons. Therefore, a positive corneal reflex indicates intact medullary brainstem function.

Q

Neurologic findings NOT suggesting a myopathy:
a. Facial dystonia
b. Intermittent fluctuating weakness within the day
c. Presence of waddling gait by inspection
d. Distal weakness < proximal weakness

A

a. Facial dystonia

a. Facial dystonia: Facial dystonia is a movement disorder characterized by involuntary muscle contractions and spasms in the face. It is not typically associated with myopathy, which refers to muscle disease or dysfunction.

b. Intermittent fluctuating weakness within the day:
Intermittent fluctuating weakness throughout the day is more characteristic of conditions such as myasthenia gravis, which is a neuromuscular junction disorder, rather than a myopathy.

c. Presence of waddling gait by inspection: A waddling gait is often observed in patients with proximal muscle weakness, which can be seen in certain myopathies such as muscular dystrophy or inflammatory myopathies.

d. Distal weakness < proximal weakness: Distal weakness that is less severe than proximal weakness can be seen in certain neuropathies, such as peripheral neuropathy, but is not typically associated with myopathy.

Q

Which of the following is the principal non-modifiable risk factor for lacunar infarction?

a. Hypercoagulable disorder
b. Smoking
c. Diabetes mellitus
d. Age
e. Hypertension

A

d. Age

Lacunar Infarction refers to a type of stroke that occurs due to the occlusion of small penetrating arteries in the brain. These arteries supply deep structures within the brain, such as the basal ganglia and internal capsule.
Among the options provided, age is considered the principal non-modifiable risk factor for lacunar infarction. As individuals age, the risk of developing lacunar infarcts increases. This is believed to be due to the cumulative effects of vascular changes, such as arteriosclerosis and small vessel disease, that occur over time.
While other risk factors such as hypertension (option e), smoking (option b), diabetes mellitus (option c), and hypercoagulable disorders (option a) can contribute to the development of lacunar infarction, age is considered the primary non- modifiable risk factor.

b. MS is approximately threefold more common in women than men
c. MS prevalence is ten to twenty folds higher in the tropics than in temperate zones
d. All are true

A

b. MS is approximately threefold more common in women than men

The age of onset for MS is typically between 20 and 40 years, and it is more common in temperate zones than in the tropics. However, MS is not ten to twenty folds higher in the tropics than in temperate zones. In fact, the prevalence of MS is much lower in the tropics than in temperate zones.
Statistics on the prevalence of MS:
* The global prevalence of MS is estimated to be 2.5 million people.
* The highest prevalence of MS is found in northern Europe, Canada, and the United States.
* The lowest prevalence of MS is found in Africa, South America, and Asia.
The reason for the higher prevalence of MS in temperate zones is not fully understood, but it is thought to be due to a combination of genetic and environmental factors.
