Question 1

Which imagine technique is most commonly used for the initial assessment of a suspected stroke?

Answer 1

CT scan

Question 2

In the context of diabetic neuropathy, what role does oxidative stress play in neuronal damage?

Answer 2

It leads to the accumulation of reactive oxygen species (ROS), damaging neuronal cells.

Question 3

Lewy bodies, a hallmark of Parkinson´s Disease, are primarily composed of which protein?

Answer 3

Alpha-synuclein

Question 4

Diabetic neuropathy can affect various types of nerves. What is a symptom of autonomic neuropathy?

Answer 4

Gastroparesis leading to nausea, vomiting and bloating

Question 5

Considering the pathpysiology of diabetic neuropathy, what describes the role of Vitamin B complex in its management?

Answer 5

It acts as an antioxidant, reducing oxidative stress on nerves, to neres

Question 6

Which is primarily responsible for the motor symptoms observed in Parkinson´s Disease?

Answer 6

Degeneration of dopaminergic neurons in the substantia nigra

Question 7

What is the role of alpha-synuclein in the pathogenesis of Parkinson´s disease?

Answer 7

Misfolds and aggregates, leading to neuronal death

Question 8

Which mechanisms is primarily involved in the pathogenesis of diabetic neuropathy?

Answer 8

Accumulation of advanced glycation end-products (AGEs) in nerve tissues

Question 9

Which pathophysiological changes is not typically associated with diabetic neuropathy?

Answer 9

Increased nerve growth factor (NGF) production

Question 10

Which symptoms is not typically associated with Parkinson´s disease?

Answer 10

Hyperreflexia

Question 11

How does the presence of Lewy bodies in various parts of the brain contribute to the range of symptoms experienced by Parkinson´s disease patients?

Answer 11

Contributing to the loss of neurons across different brain regions, affecting both motor and non-motor functions

Question 12

Which symptom is most indicative of a stroke affecting the cerebellum?

Answer 12

Ataxia

Question 13

The risk of developing diabetic neuropathy can be reduced by controlling hyperglycemia. What is the proposed mechanism for this effect?

Answer 13

Reduction in oxidative stress and inflammation in nerve tissues

Question 14

Answer 16

Demyelination of neurons in the central nervous system

Question 17

What is the primary reason for the increased risk of foot ulcers in patients with diabetic neuropathy?

Decreased sensation leading to unrecognized injury

Question 18

Which MRI finding is most indicative of MS?

Answer 18

Periventricular white matter lesions with an ovoid shape

Question 19

Considering the pathophysiology of MS, why is physical therapy often recommended as part of the treatment plan?
