Question

this progressive disorder causes degeneration of neurons in the part of the brain that controls movement and leads to tremors, shuffling gait and slowness of movement is called:

muscular dystrophy
parkinsons disease
cerebral palsy
none of the above

Explanation:

Analyze the clinical symptoms

The question describes a progressive disorder characterized by the degeneration of neurons in a brain region controlling movement. The key clinical signs presented are:

• Tremors (resting tremors)
• Shuffling gait (difficulty walking with short, dragging steps)
• Slowness of movement (bradykinesia)

Match symptoms to neurodegenerative disorders

Using our knowledge of Neurodegenerative Disorders, we evaluate the options:

• Muscular Dystrophy: A genetic muscle-wasting disease, not primarily a degeneration of brain neurons.
• Parkinson's Disease: A progressive nervous system disorder affecting movement due to loss of dopamine-producing neurons in the substantia nigra. Classic symptoms include resting tremors, bradykinesia (slowness of movement), rigidity, and a characteristic shuffling gait.
• Cerebral Palsy: A congenital, non-progressive movement disorder caused by abnormal brain development or damage before, during, or shortly after birth, rather than a progressive adult-onset degeneration.

Confirm the correct diagnosis

The clinical triad of tremors, shuffling gait, and bradykinesia is the hallmark presentation of Parkinson's disease. Therefore, the correct option is Parkinson's Disease.

Answer:

• Muscular Dystrophy
• Parkinson's Disease (Correct answer)
• Cerebral Palsy
• None of the above
