Management and Treatment of Asthenia (Weakness or Lack of Energy)
The management of asthenia requires a systematic diagnostic approach to identify and treat the underlying cause, as up to 50% of cases are related to depression, while the remaining cases may be due to various medical conditions requiring specific interventions. 1
Diagnostic Evaluation
Differentiate true asthenia (subjective feeling of weakness not necessarily related to effort) from related symptoms such as weakness, dizziness, or dyspnea, as patients often confuse these sensations 1
Classify asthenia based on duration:
- Prolonged fatigue: lasting more than one month
- Chronic fatigue: persisting longer than 6 months 1
Consider chronic fatigue syndrome (CFS) as a diagnosis of exclusion when symptoms persist for more than 6 months without identifiable cause, using the 1994 international consensus criteria 1
Common Causes of Asthenia
Depression is the most common cause, accounting for approximately 50% of all cases 1
Other frequent causes include:
Treatment Approach
The most effective treatment strategy is to identify and address the underlying cause, though approximately 20% of patients may remain without a definitive diagnosis 1
For depression-related asthenia:
For cardiovascular or cerebrovascular-related asthenia:
For post-viral asthenia:
For senile asthenia syndrome:
Monitoring and Follow-Up
Regular assessment of symptom improvement is essential, with follow-up appointments scheduled based on severity and underlying cause 5
Monitor for development or worsening of cognitive disorders, which frequently accompany asthenia 4
Evaluate treatment response and adjust therapy as needed, particularly for chronic cases 5
Patient Education
Explain the nature of asthenia as a defense mechanism signaling energy resource depletion 4
Provide realistic expectations about recovery timeframes based on the underlying cause 1
Emphasize the importance of adequate rest, proper nutrition, and appropriate physical activity levels 6
Discuss the significant social and economic impact of untreated asthenia to encourage adherence to treatment plans 1
