Dementia Complex Acquired Immune Deficiency Syndrome is a medical condition that affects cognitive functions, immunity, and behavior. The term is a bit too specific to have antonyms, as it describes a unique set of symptoms and consequences associated with a particular illness. However, the words "dementia," "complex," "acquired," "immune deficiency," and "syndrome" all have antonyms that relate to their standard definitions. For instance, antonyms for dementia include clarity, sanity, and lucidity, while antonyms for complex could be simple or straightforward. Antonyms for acquired could be natural or inherent. Antonyms for immune deficiency may include healthy and robust, and antonyms for syndrome could be normality or usual state.
