    • A.

      MS

    • B.

      Parkinson's

    • C.

      Huntington's

    • D.

      ALS

    Correct Answer
    B. Parkinson's
    Explanation
    Parkinson's disease is a progressive degenerative disorder that primarily affects motor function. It is characterized by the loss of extra pyramidal activity, which refers to the dysfunction of the basal ganglia, a part of the brain involved in motor control. This leads to symptoms such as tremors, rigidity, and bradykinesia (slowness of movement). The other options, MS (multiple sclerosis), Huntington's disease, and ALS (amyotrophic lateral sclerosis), are not specifically associated with the loss of extra pyramidal activity or basal ganglia dysfunction.

    • B.

      Parkinson's

    • C.

      Huntington's

    • D.

      ALS

    Correct Answer
    C. Huntington's
    Explanation
    Huntington's disease is a genetic disorder characterized by degenerative progressive atrophy of the brain. It is caused by a mutation in the huntingtin gene, leading to the production of a toxic protein that damages nerve cells in the brain. This results in a gradual decline in motor control, cognitive abilities, and psychiatric symptoms. The disease typically manifests in mid-adulthood and progresses over time, ultimately leading to severe disability and death. Therefore, Huntington's disease is the correct answer in this case.

    Muscle wasting disease due to degenerative hardening of the corticospinal tract

    • A.

      ALS

    • B.

      Huntington's

    • C.

      Parkinson's

    • D.

      MS

    Correct Answer
    A. ALS
    Explanation
    ALS, or Amyotrophic Lateral Sclerosis, is a neurodegenerative disease that causes muscle wasting due to the degenerative hardening of the corticospinal tract. This condition affects the motor neurons in the brain and spinal cord, leading to the progressive loss of muscle control and eventual paralysis. ALS is characterized by muscle weakness, difficulty in speaking, swallowing, and breathing, and it ultimately leads to death. While Huntington's, Parkinson's, and MS are also neurodegenerative diseases, they do not specifically cause degenerative hardening of the corticospinal tract like ALS does.

    Pathophysiology involved with Multiple sclerosis is

    • A.

      Basal ganglia disfunction

    • B.

      Degeneration of neurons

    • C.

      Depletion of neurotransmitters

    • D.

      Demyelination

    • E.

      Hardening of corticospinal tract

    Correct Answer
    D. Demyelination
    Explanation
    The correct answer is demyelination. Multiple sclerosis is a chronic autoimmune disease where the immune system mistakenly attacks the protective covering of nerve fibers called myelin. This leads to the destruction of myelin, causing interruptions in the normal flow of electrical impulses along the nerves. Demyelination is a key feature of multiple sclerosis and is responsible for the various neurological symptoms experienced by individuals with the condition.

    • B.

      ALS

    • C.

      Huntington's

    • D.

      Parkinson"

    Correct Answer
    A. MS
    Explanation
    Plaque is found in multiple sclerosis (MS). MS is a chronic autoimmune disease that affects the central nervous system, including the brain and spinal cord. Plaque refers to the accumulation of damaged nerve fibers, immune cells, and other substances in the affected areas. These plaques disrupt the normal functioning of neurons, leading to various neurological symptoms such as muscle weakness, coordination difficulties, and cognitive impairment. While plaques can also be found in other neurodegenerative disorders like ALS, Huntington's disease, and Parkinson's disease, MS is specifically known for its characteristic plaques.

    • C.

      Huntington's

    • D.

      Parkinson's

    Correct Answer
    C. Huntington's
    Explanation
    Huntington's disease is an inherited neurological disorder caused by a dominant gene. This means that if one parent has the gene mutation, there is a 50% chance of passing it on to their children. The disease is not sex-linked, so it can be inherited from either the mother or the father. Symptoms usually appear in adulthood and include involuntary movements, cognitive decline, and psychiatric problems.

    High doses of corticosteroids is a treatment for

    • A.

      ALS

    • B.

      Parkinson's

    • C.

      MS

    • D.

      Huntington's

    Correct Answer
    C. MS
    Explanation
    High doses of corticosteroids are a treatment for multiple sclerosis (MS) because they help reduce inflammation and suppress the immune system. In MS, the immune system mistakenly attacks the protective covering of nerve fibers in the central nervous system, leading to inflammation and damage. Corticosteroids, such as prednisone or methylprednisolone, can help reduce this inflammation and alleviate symptoms during a relapse or flare-up of MS. However, it is important to note that corticosteroids are not a long-term solution for MS and are typically used for short periods to manage acute symptoms.

    • A.

      ALS

    • B.

      MS

    • C.

      Huntington's

    • D.

      Parkinson's

    Correct Answer
    B. MS
    Explanation
    Visual problems are often associated with multiple sclerosis (MS). MS is a neurological condition that affects the central nervous system, including the optic nerves responsible for vision. Visual symptoms such as blurred or double vision, eye pain, and difficulty focusing are common in MS. These visual problems can be helpful in diagnosing MS, as they are often one of the initial symptoms experienced by individuals with the condition. Other conditions listed, such as ALS, Huntington's, and Parkinson's, may have their own distinct symptoms but are not typically associated with visual problems as a prominent diagnostic feature.

    Rate this question:

  • 16. 

    ALS affects UMN's in the cerebral cortex and LMN's in the brainstem and spinal cord.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    ALS (Amyotrophic lateral sclerosis) is a neurodegenerative disease that affects both the upper motor neurons (UMNs) in the cerebral cortex and the lower motor neurons (LMNs) in the brainstem and spinal cord. This leads to the progressive degeneration and loss of muscle control and function. The statement correctly states that ALS affects UMN's in the cerebral cortex and LMN's in the brainstem and spinal cord, making the answer true.

    Rate this question:

  • 17. 

    UMN's damage with ALS cause all but......

    • A.

      Decreased muscle tone

    • B.

      Spastic paralysis

    • C.

      Hyperreflexia

    • D.

      Weakness in hands and arms

    Correct Answer
    A. Decreased muscle tone
    Explanation
    UMN's damage with ALS causes decreased muscle tone. This means that the muscles become less tense or rigid, resulting in a loss of muscle strength and coordination. This is a characteristic symptom of ALS, as the upper motor neurons (UMNs) responsible for initiating voluntary muscle movements are damaged. Other symptoms mentioned in the options, such as spastic paralysis, hyperreflexia, and weakness in hands and arms, are not associated with UMN damage in ALS.

    Rate this question:

  • 18. 

    LMN damage with ALS causes flaccid paralysis, decreased muscle tone and decreased reflexes.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true. ALS, or amyotrophic lateral sclerosis, is a neurodegenerative disease that affects the nerve cells responsible for controlling voluntary muscle movement. When the LMN (lower motor neurons) are damaged in ALS, it leads to flaccid paralysis, which is characterized by weak and floppy muscles. This condition also results in decreased muscle tone and decreased reflexes.

    • A.

      ALS

    • B.

      MS

    • C.

      Huntington's

    • D.

      Parkinson's

    Correct Answer
    D. Parkinson's
    Explanation
    The symptoms described in the question, such as bradykinesia (slowness of movement) and festinating gait (shuffling gait), are classic signs of Parkinson's disease. Parkinson's disease is a neurodegenerative disorder that primarily affects individuals over the age of 60. The substantia nigra, a region of the brain involved in movement control, is typically affected in Parkinson's disease. ALS (Amyotrophic lateral sclerosis) is a motor neuron disease characterized by muscle weakness and atrophy, MS (Multiple sclerosis) is an autoimmune disease affecting the central nervous system, and Huntington's disease is a genetic disorder causing the progressive breakdown of nerve cells in the brain.

    Treatment may include dopamine replacement

    • A.

      ALS

    • B.

      MS

    • C.

      Parkinson's

    • D.

      Huntington's

    Correct Answer
    C. Parkinson's
    Explanation
    Treatment for Parkinson's disease often involves dopamine replacement therapy. Parkinson's is a neurodegenerative disorder that affects dopamine-producing cells in the brain. Dopamine is a neurotransmitter that plays a crucial role in movement and coordination. As the disease progresses, the brain produces less dopamine, leading to symptoms such as tremors, stiffness, and difficulty with balance and coordination. Dopamine replacement therapy aims to supplement the brain's dopamine levels by administering medications that can mimic its effects. This treatment can help alleviate the motor symptoms associated with Parkinson's and improve the patient's quality of life.
