Final answer:
Sasha's severe intellectual disability, possibly caused by exposure to drugs, reflects significant limitations in intelligence and adaptive behavior.
Step-by-step explanation:
Sasha is diagnosed with a severe intellectual disability, which implies significant limitations in both intellectual functioning and in adaptive behavior, affecting many everyday social and practical skills. While the exact cause of Sasha's condition isn't stated, it's mentioned that situational factors such as exposure to drugs could be the likely cause. Intellectual disabilities can have various sources, including genetic conditions like Down syndrome, environmental factors such as exposure to drugs or alcohol during pregnancy, and sometimes birth complications or infections.
It's important to distinguish intellectual disability from learning disabilities and developmental disorders like Autism Spectrum Disorder (ASD), which have different characteristics and implications on an individual's learning and social abilities.
