Acquired neurasthenia is a medical condition characterized by physical and mental exhaustion, caused by excessive stress, anxiety, and overwork. The word "acquired" implies that this condition is not inherited, but rather developed over time. The term "neurasthenia" derives from the Greek words "neuron" (nerve) and "asthenia" (weakness), meaning weakness of the nerves. Some of the antonyms for acquired neurasthenia include vitality, energy, strength, resilience, and robustness. These words represent the opposite of the symptoms associated with neurasthenia and suggest a state of well-being and optimal health. To avoid acquiring neurasthenia, it is essential to manage stress levels effectively, practice self-care, maintain a healthy lifestyle, and seek medical attention if symptoms persist.
