Cerebral Palsy Indian Medical PG Practice Questions and MCQs

Question 1: A 55-year-old male, known smoker, complains of calf pain while walking. He experiences calf pain while walking but can continue walking with effort. Which grade of claudication does this patient fall under?

A. Grade I (Mild claudication)
B. Grade II (Moderate claudication) (Correct Answer)
C. Grade III (Severe claudication)
D. Grade IV (Ischemic rest pain)

Explanation: ***Grade II (Moderate claudication)*** - **Grade II claudication** is characterized by **intermittent claudication** where the patient experiences pain while walking but can **continue walking with effort**. - This level of claudication reflects a moderate degree of peripheral arterial disease, where blood flow is sufficiently compromised to cause pain with exertion but not severe enough to force immediate cessation of activity. - The patient in this scenario can continue ambulation despite discomfort, which is the defining feature of this grade. *Grade I (Mild claudication)* - **Grade I claudication** involves discomfort or pain that the patient can **tolerate without significantly altering their gait or pace**. - In this stage, the pain is minimal, and the patient may perceive it as a dull ache or mild fatigue rather than true pain. - Walking can continue without significant effort or limitation. *Grade III (Severe claudication)* - **Grade III claudication** is marked by pain that is **severe enough to stop the patient from walking within a short distance** (typically less than 200 meters). - The pain forces the patient to rest and recover before they can resume walking. - This represents significant functional limitation in daily activities. *Grade IV (Ischemic rest pain)* - **Grade IV**, also known as **critical limb ischemia**, involves **pain even at rest**, especially in the feet or toes, often worsening at night when the limb is elevated. - This stage indicates severe arterial obstruction and is frequently associated with **ulcers, non-healing wounds, or gangrene**. - This represents advanced peripheral arterial disease requiring urgent intervention. **Note:** This grading system is a simplified clinical classification. The standard medical classifications for peripheral arterial disease are the **Fontaine classification** (Stages I-IV) and **Rutherford classification** (Categories 0-6).

Question 2: Match the following drugs in Column A with their contraindications in Column B. | Column A | Column B | | :-- | :-- | | 1. Morphine | 1. QT prolongation | | 2. Amiodarone | 2. Thromboembolism | | 3. Vigabatrin | 3. Pregnancy | | 4. Estrogen preparations | 4. Head injury |

A. A-1, B-3, C-2, D-4
B. A-4, B-1, C-3, D-2 (Correct Answer)
C. A-3, B-2, C-4, D-1
D. A-2, B-4, C-1, D-3

Explanation: ***A-4, B-1, C-3, D-2*** - **Morphine** is contraindicated in **head injury** as it can increase intracranial pressure and mask neurological symptoms. - **Amiodarone** is contraindicated in patients with **QT prolongation** due to its risk of inducing more severe arrhythmias like Torsades de Pointes. - **Vigabatrin** is contraindicated during **pregnancy** due to its potential for teratogenicity and adverse effects on fetal development. - **Estrogen preparations** are contraindicated in patients with a history of **thromboembolism** due to their increased risk of blood clot formation. *A-1, B-3, C-2, D-4* - This option incorrectly matches **Morphine** with QT prolongation and **Estrogen preparations** with head injury, which are not their primary contraindications. - It also incorrectly links **Vigabatrin** with thromboembolism and **Amiodarone** with pregnancy. *A-3, B-2, C-4, D-1* - This choice incorrectly associates **Morphine** with pregnancy and **Vigabatrin** with head injury, which are not the most critical or direct contraindications. - It also misaligns **Amiodarone** with thromboembolism and **Estrogen preparations** with QT prolongation. *A-2, B-4, C-1, D-3* - This option incorrectly matches **Morphine** with thromboembolism and **Amiodarone** with head injury, which are not their most significant contraindications. - It also incorrectly links **Vigabatrin** with QT prolongation and **Estrogen preparations** with pregnancy.

Question 3: A newborn developed periventricular leukomalacia following ischemic infarction. What can be the most common sequelae in this child?

A. Hypotonia
B. Spastic quadriplegia
C. Spastic diplegia (Correct Answer)
D. Intellectual disability

Explanation: ***Spastic diplegia*** - **Periventricular leukomalacia (PVL)** primarily damages the **white matter** adjacent to the ventricles, including descending motor tracts controlling leg movement. - This specific damage pattern often leads to **spasticity predominantly in the lower limbs**, characteristic of spastic diplegia. *Hypotonia* - While hypotonia may be present acutely in some hypoxic-ischemic injuries, it is not the **most common chronic sequela** of PVL. - PVL specifically damages **upper motor neuron pathways**, predominantly leading to spasticity rather than hypotonia in the long term. *Spastic quadriplegia* - Spastic quadriplegia implies **severe motor impairment** in all four limbs, usually resulting from more widespread or extensive brain damage. - PVL typically affects the motor tracts to the legs more severely, making spastic diplegia a more common and specific outcome. *Intellectual disability* - While **cognitive impairment** can be a complication of PVL, it is not the most common **motor sequela**. - **Motor disorders**, particularly spastic diplegia, are the hallmark clinical presentation following PVL.

Question 4: The type of cerebral palsy characterized by constant and uncontrolled motion of involved muscles is called:

A. Athetosis (Correct Answer)
B. Rigidity
C. Spasticity
D. Ataxia
E. Hypotonia

Explanation: ***Athetosis*** - **Athetoid cerebral palsy** is characterized by **involuntary, slow, writhing movements** affecting the limbs and often the face and trunk. - These uncontrolled movements are due to damage to the **basal ganglia**, responsible for motor control and coordination. *Rigidity* - **Rigidity** is a form of hypertonia characterized by a constant, uniform resistance to passive movement throughout the range of motion. - It does not specifically describe constant and uncontrolled motion, but rather **increased muscle tone** that hampers movement. *Spasticity* - **Spasticity** is a type of hypertonia characterized by a velocity-dependent increase in muscle tone, often with a "clasp-knife" phenomenon. - It involves **exaggerated reflexes** and muscle stiffness, which is different from continuous, uncontrolled movements. *Ataxia* - **Ataxia** refers to impaired coordination and balance, leading to unsteady gait and difficulty with fine motor skills. - It is caused by damage to the **cerebellum** and typically involves a lack of smooth, coordinated movement rather than uncontrolled motion of involved muscles. *Hypotonia* - **Hypotonia** refers to decreased muscle tone, resulting in floppiness and reduced resistance to passive movement. - It is the opposite of the uncontrolled, involuntary movements seen in athetosis and is sometimes seen in early infancy before other CP types become apparent.

Question 5: In a 9-month-old child, which of the following reflexes is considered most abnormal?

A. Parachute reflex
B. Righting reflex
C. Asymmetric tonic neck reflex (ATNR) (Correct Answer)
D. None of the options

Explanation: ***Asymmetric tonic neck reflex (ATNR)*** - The **ATNR** (fencing reflex) typically **disappears by 6 months of age**. Persistence beyond this age, especially at 9 months, is a critical indicator of potential neurological dysfunction or developmental delay. - Its presence can hinder normal development, such as rolling, crawling, and reaching milestones like bringing hands to midline, and is therefore considered the **most abnormal** at this age. *Parachute reflex* - The **parachute reflex** (forward protective extension) typically emerges between **6 to 9 months of age** and persists throughout life. - Its presence at 9 months indicates a normally developing protective mechanism and is therefore **normal**, not abnormal. *Righting reflex* - The **righting reflex** (which includes various head and body righting reactions), allows the infant to maintain an upright head position and orient the body relative to the head and gravity. - These reflexes gradually develop and are often well-established by **6-12 months**, being crucial for independent sitting and balance, making its presence at 9 months **expected and normal**. *None of the options* - This option is incorrect because the **Asymmetric Tonic Neck Reflex (ATNR)** is indeed considered abnormal if present at 9 months of age, indicating a potential developmental concern.

Question 6: Scissor gait is seen in which of the following conditions:

A. Polio
B. Cerebral palsy (Correct Answer)
C. Hyperbilirubinemia
D. Hyponatremia

Explanation: ***Cerebral palsy*** - **Scissor gait** is a characteristic presentation in individuals with **spastic cerebral palsy**, due to hyperactivity of adductor muscles, causing the legs to cross over each other. - This **spasticity** often results from damage to the brain's motor control centers during development. *Polio* - **Polio** primarily causes **flaccid paralysis** due to damage to anterior horn cells, leading to muscle weakness and atrophy, not spasticity. - The gait in polio is often characterized by muscle weakness, leading to a **waddling or steppage gait**, not scissoring. *Hyperbilirubinemia* - Severe **hyperbilirubinemia** in neonates can lead to **kernicterus**, causing **choreoathetosis**, dystonia, and hearing loss. - While it affects motor control, it typically results in involuntary movements and muscle rigidity (dystonia), but **scissor gait** is not a hallmark. *Hyponatremia* - **Hyponatremia** is an electrolyte imbalance that can cause neurological symptoms such as confusion, seizures, and coma. - It does not directly cause specific gait abnormalities like **scissor gait**; any gait disturbances would be secondary to altered mental status or seizures.

Question 7: What is the significance of the persistence of the asymmetric tonic neck reflex in a 9-month-old infant?

A. Decreased muscle tone
B. Increased muscle tone (Correct Answer)
C. Normal phenomenon
D. None of the options

Explanation: ***Increased muscle tone*** - The **asymmetric tonic neck reflex (ATNR)** should integrate by **6 months of age**, and its persistence beyond this period is a sign of **neurological dysfunction**. - Persistent primitive reflexes, including ATNR, are often associated with **upper motor neuron lesions** and can manifest as increased muscle tone or **spasticity**. *Decreased muscle tone* - **Decreased muscle tone**, or **hypotonia**, is typically associated with **lower motor neuron lesions** or certain genetic conditions, not the persistence of primitive reflexes. - While some neurological conditions can cause hypotonia, persistent ATNR is a hallmark of problems leading to **hypertonia**. *Normal phenomenon* - The persistence of the ATNR beyond **6 months of age** is considered abnormal and indicates a potential developmental delay or neurological issue. - In a **9-month-old**, the reflex should have fully integrated, and its presence warrants further investigation. *None of the options* - As the persistence of the ATNR is indeed a significant finding, associated with increased muscle tone, this option is incorrect.

Question 8: Which of the following are tools commonly used in the evaluation of children with cerebral palsy for motor function and spasticity assessment? I. Gross Motor Function Classification System II. Medical Research Council System III. Modified Connors Scale (Connors-II) IV. Modified Ashworth Scale Select the correct answer using the code given below:

A. III and IV
B. I and IV (Correct Answer)
C. I and II
D. II and III

Explanation: ***Correct: I and IV*** - The **Gross Motor Function Classification System (GMFCS)** is the gold standard tool to classify gross motor function in children with **cerebral palsy** based on self-initiated movement and functional limitations across five levels (I-V). - The **Modified Ashworth Scale** is the most widely used clinical tool for assessing **spasticity** and muscle tone in cerebral palsy, grading resistance to passive movement on a 0-4 scale. - These two tools directly address **motor function classification** and **spasticity assessment** as required in the question. *Incorrect: III and IV* - While the **Modified Ashworth Scale (IV)** is correctly identified for spasticity assessment, the **Modified Connors Scale (Connors-II)** is used exclusively for evaluating **Attention-Deficit/Hyperactivity Disorder (ADHD)**, not motor function or spasticity in cerebral palsy. *Incorrect: I and II* - The **GMFCS (I)** is correctly identified for motor function classification in cerebral palsy. - However, the **Medical Research Council (MRC) System** is primarily used for **muscle strength grading** (0-5 scale) in conditions like peripheral neuropathy, stroke, or myopathy—not for motor function classification or spasticity assessment specific to cerebral palsy. *Incorrect: II and III* - Both tools are inappropriate for the stated purpose: the **MRC System** assesses muscle strength (not CP-specific motor function classification), and the **Modified Connors Scale** evaluates ADHD symptoms. - Neither tool is standard for evaluating motor function or spasticity in cerebral palsy.

Question 9: Which of the following is a FALSE statement regarding Cerebral Palsy?

A. Cerebral palsy occurs due to one time insult to developing fetal brain
B. Periventricular leucomalacia causes spastic diplegia
C. Persistent cortical thumb after 3 months of age is seen in spastic cerebral palsy
D. Birth trauma is the most common cause of cerebral palsy (Correct Answer)

Explanation: ***Birth trauma is the most common cause of cerebral palsy*** - While birth trauma can contribute to brain injury, **prematurity** and **intrauterine growth restriction** are actually more frequent risk factors for cerebral palsy. - The majority of cerebral palsy cases originate from prenatal or perinatal events, with **birth asphyxia** being a less common cause than historically believed. *Cerebral palsy occurs due to one time insult to developing fetal brain* - Cerebral palsy is defined by a **non-progressive disturbance** in the developing fetal or infant brain, which is indeed a "one time insult" rather than a degenerative process. - This insult can occur before, during, or shortly after birth, leading to permanent but **non-worsening** motor impairments. *Periventricular leucomalacia causes spastic diplegia* - **Periventricular leucomalacia (PVL)**, a type of white matter brain injury, is strongly associated with **spastic diplegia**, particularly in premature infants. - PVL damages the periventricular white matter that contains descending motor tracts to the lower limbs, hence causing a **diplegic** (legs more affected than arms) presentation. *Persistent cortical thumb after 3 months of age is seen in spastic cerebral palsy* - A **cortical thumb**, where the thumb is held adducted and flexed across the palm, can be a sign of **upper motor neuron lesion** or spasticity. - Its persistence beyond 3 months of age is an indicator of neurological dysfunction and is often observed in infants who develop **spastic cerebral palsy**.

Question 10: In a small child diagnosed with H. influenzae meningitis, what investigation must be done before discharging him from the hospital?

A. Hearing assessment (Correct Answer)
B. CT scan
C. X-ray skull
D. MRI

Explanation: ***Hearing assessment*** - **Sensorineural hearing loss** is a significant and common complication of *H. influenzae* meningitis, occurring in up to 30% of children. - Early detection through a **hearing assessment** is crucial for intervention and to minimize long-term developmental impact. *CT scan* - A CT scan is typically performed during the acute phase of meningitis to rule out complications like **hydrocephalus** or **brain abscess**, not routinely before discharge for long-term sequelae. - While it can identify structural abnormalities, it does not directly assess **auditory function**. *X-ray skull* - An X-ray of the skull has very limited utility in the diagnosis or follow-up of meningitis. - It does not provide information about brain pathology or potential **hearing damage**. *MRI* - MRI is a more sensitive imaging modality than CT for detecting subtle brain parenchymal changes and is sometimes used in complicated cases of meningitis. - However, like CT, it is not the primary investigation required to assess for **hearing loss** as a post-meningitis sequela before discharge.
