Seeking info and medication for nervous asthenia

Dear Ask The Doctor: Can you offer me more info about nervous asthenia and any medication I can take?

Dear Rebeca: Nervous fatigue or neurasthenia is a psychological disorder characterized by chronic fatigue and weakness, loss of memory, and generalized aches and pains, formerly thought to result from exhaustion of the nervous system. Neurasthenia is a complex phenomenon involving the central nervous system (CNS) and muscle. It is though that increase in the levels of 5-HT, serotonin and cytokines may bring about the disorder.  Though there may be no definite therapy, a balanced diet, moderate exercise, and muscle and stress relaxation techniques like meditation may help.
