In contrast, the occurrence of asthenic disorders due to a more diverse and often associated with other available pathological causes. Sam asthenic syndrome status as "abnormal exhaustion after normal activity, reducing power to solve problems that require effort and attention, or generalized decrease in ability to act", consists of three components: - the actual manifestation of asthenia - disorder caused by the underlying pathological fatigue state - disorder caused by the reaction of the individual to the disease.
