Step-by-step explanation:
One historical case study is that of Helen Keller. Helen Keller was an American author, political activist, and lecturer who was both blind and deaf. Her vision and hearing loss resulted from an illness, most likely scarlet fever or meningitis, which she contracted at the age of 19 months. As a result of her dual sensory impairments, Helen Keller faced immense challenges in communication and understanding the world around her.
With the help of her teacher and companion, Anne Sullivan, Keller learned to communicate through a tactile manual alphabet. Over time, she not only mastered language but also went on to achieve significant academic accomplishments. She graduated from Radcliffe College, authored books, and became an advocate for people with disabilities.
Helen Keller's life is a powerful example of how determination, education, and support can overcome even the most profound neurological challenges, demonstrating the resilience of the human spirit.
