Notes on Meaning

• Clinical vs. General Use: While "asthenia" is a formal medical term, its core meaning of "abnormal weakness" is its primary definition. It is distinct from simple tiredness, implying a more profound or pathological loss of energy.
• Symptomatic Nature: It is crucial to understand that asthenia is a symptom. A diagnosis seeks to find the underlying cause (e.g., anemia, infection, chronic fatigue syndrome) of the asthenia.
