Final answer:
The symptoms described for Benjamin Titus—right foot-drop and advanced spasticity of his left arm—are most indicative of (B) Cerebral Palsy (CP). CP is characterized by impaired movement and muscle control, which aligns with Benjamin's symptoms, distinguishing it from other conditions listed such as Muscular Dystrophy, Down Syndrome, and Autism Spectrum Disorder.
Step-by-step explanation:
Given the information about Benjamin Titus, a 14-year-old with right foot-drop and advanced spasticity of his left arm, the most likely diagnosis from the options provided would be B) Cerebral Palsy. A collection of conditions known as cerebral palsy (CP) impact a person's mobility, balance, and posture. A person's inability to coordinate their muscles due to improper brain development or brain damage during development is the cause of cerebral palsy (CP). This is consistent with the symptoms mentioned, such as spasticity, a condition in which particular muscles are always tightened, and foot-drop, a condition in which elevating the front portion of the foot is difficult. This contraction can impair speech, gait, and mobility by causing the muscles to stiffen or tighten.
While there are other conditions such as Muscular Dystrophy and Down Syndrome that can affect muscle function and development, the symptoms of foot-drop and spasticity align more closely with those of Cerebral Palsy. Autism Spectrum Disorder (ASD) primarily affects social interaction and behavior, rather than motor function.
It is also important to note that foot-drop can also be associated with other neurological conditions, but given the specific symptom of left arm spasticity in addition to the foot-drop, Cerebral Palsy is the most fitting diagnosis from the provided options.
