Paralytic idiocy is a term used in medical literature to describe a severe cognitive impairment and physical disability in individuals. However, it is important to note that the use of this term has become outdated and is no longer favored due to its derogatory connotation. Nowadays, professionals and society prefer more respectful and inclusive terminology. Some synonymous terms that are used to describe similar conditions include profound intellectual disability, severe cognitive impairment, profound mental retardation, and severe developmental delay. These terms are more sensitive and reflect a greater understanding and empathy towards individuals who may be experiencing such challenges.
