What is neurasthenia?

Neurasthenia is the term given in psychiatry to a neurotic disorder that manifests itself as an unexplained exhaustion that occurs after physical or mental exertion. Its name comes from the words "neuro" (which refers to the nervous system and particularly the mind) and "asthenia" (which is a feeling of weakness or physical exhaustion).

Neurasthenia is also known by other names such as chronic asthenia, Da Costa syndrome, functional cardiovascular disease, soldier’s heart among others. This disorder decreases the ability to perform daily activities and if its duration is prolonged for a long time, can lead to other disorders such as depression and anxiety.

It is often thought to be hereditary or caused by a very strong emotional disorder. The causes of neurasthenia can be very trivial, such as frequent conflict at work, severe work fatigue, or loss of a loved one.

Sexual neurasthenia is sometimes characterized by sexual dysfunction.

Regardless of it causes, it is important to take early action to prevent this disorder from causing irreparable health damage.
